comment #6.

I actually have no idea in what other ways it may be used, though I didn't
think that running syzkaller was the only use case. It always feels like most
bugs in the kernel are in obscure drivers, but then most of the kernel code
consists of obscure drivers ;-)
Here are some warnings in code that is actually being run. For the full output
I see on linux-next, have a look at https://pastebin.com/CMJiUsuR. There
are a couple of other warnings mixed in there as well that I'm working on
addressing, but it's mainly the stack overflow once I turn on
CONFIG_KASAN_EXTRA.

Let me decrypt how clang generates the red zones. I can probably quickly come
up with a patch that will do the dynamic red zone size allocation. Having that
you'll be able to rebuild kernel and catch remaining issues.

The fix for pr83823 seems to have fixed the problems reported in
comment #0 and comment #2 for 8.0 trunk. The issues persist up to
7.2 (haven't checked 7.3).

--- Comment #3 from Evan Nemerson <evan@coeus-group.com> ---
(In reply to Jakub Jelinek from comment #2)
> _OPENMP_SIMD is a bad idea, that namespace is reserved for OpenMP, so unless

Fair enough, I'll propose it to the OpenMP people:
http://forum.openmp.org/forum/viewtopic.php?f=23&t=2031
> Why do you need a macro? Just use #pragma omp simd etc. unconditionally,
> compilers that don't have support for such pragmas will just ignore those.
Not necessarily; often they'll emit warnings (for GCC, -Wall even includes
-Wunknown-pragmas). I'd much rather use the preprocessor in my code than teach
people to disable warnings.
I need to support alternatives in my code. For example, for SIMDe
(<https://github.com/nemequ/simde>), I try to support OpenMP SIMD and Cilk
Plus, as well as compiler-specific pragmas for GCC (GCC ivdep), ICC (simd), and
clang (clang loop ...), and I'd be happy to add more as necessary. I'd rather
not end up with something like
#pragma omp simd
#pragma simd
#pragma GCC ivdep
#pragma clang loop vectorize(enable)
for (...) { ... }
I'd much rather just have a few macros which will expand to the right pragma
based on preprocessor macros. Right now I'm stuck using the much less
expressive ivdep syntax for GCC unless *full* OpenMP support is enabled (or
someone defines a macro manually to indicate OpenMP SIMD support).

0
10
If using "= default" on a constexpr copy/move assignment operator, an constexpr
evaluation involving this operator produces an invalid result. In this case,
m_value contains 0 instead of 10.
Its usage in a non-constexpr context yields the expected value.

Note that _REENTRANT is a no-op with glibc 2.25 or later unless you
specifically select an old standard version (in which case it's an alias
for _POSIX_C_SOURCE=199506L).

David,
This appears to be fixed on trunk, and broken on the
6 and 7 branches. I don't have older versions lying
around to test.
gfcx -o z a.f90 && ./z
123456789

troutmask:sgk[206] gfc6 -o z a.f90 && ./z
123456789

I'm not sure if a back port of the patch (if one can even
be identified) can be applied to branches due to changes
in how strings are handled.
I'll mark this as NEW and hopefully others can chime in.

--- Comment #11 from Jeffrey A. Law <law at redhat dot com> ---
Just to record some thoughts.
The implementation of the "clobbered by longjmp" warning essentially looks at
the objects that are live at the setjmp point. In theory we can do better when
we're dealing with setjmp/sigsetjmp (but not getcontext for example).
In theory we can look at the code after the setjmp for this kind of pattern:
(insn 15 14 21 2 (set (reg:SI 91 [ <retval> ])
(reg:SI 0 ax)) "j.c":18 86 {*movsi_internal}
(expr_list:REG_DEAD (reg:SI 0 ax)
(nil)))
(insn 21 15 22 2 (set (reg:CCZ 17 flags)
(compare:CCZ (reg:SI 91 [ <retval> ])
(const_int 0 [0]))) "j.c":18 7 {*cmpsi_ccno_1}
(nil))
(jump_insn 22 21 23 2 (set (pc)
(if_then_else (eq (reg:CCZ 17 flags)
(const_int 0 [0]))
(label_ref 28)
(pc))) "j.c":18 672 {*jcc}
(expr_list:REG_DEAD (reg:CCZ 17 flags)
(int_list:REG_BR_PROB 719407028 (nil)))
-> 28)
Since in the longjmp case, we know this will fallthru, we look at the what's
live-in in the fallthru successor. If the test were inverted we'd (of course)
look at the live in of the target of the branch. THat live-in set is what we
want to use to compute setjmp_crosses rather than what's actually live at the
setjmp (which is overly-conservative as it is the union of what's live on both
paths after the setjmp, only one of which we care about).
The implementation would be somewhat gross. It'd have to account for the
differences between setjmp/sigsetjmp and things like savectx, vfork, and
getcontext. It might be somewhat fragile since we'd be matching a series of
insns which could look radically different on some targets. *But* a proof of
concept does seem to work. I'm going to try to polish that up.
I haven't check if that addresses any of Florian's concerns from 61118.
There's a reasonable chance it will.
Alternately this could be done on gimple, but I suspect factoring of the
abnormal dispatcher as well as the inaccurate CFG will kill us.

--- Comment #9 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
Pardom for taking so long to chime in.
I suspect the source of the problem is the lack of internal view reset
computations. Without that, the assembler gets an uninterrupted chain of
symbolic views, in which each view is computed based on the view before it and
the offset between the addresses in which they were issued. Depending on the
order in which the assembler attempts to resolve each view to a constant, it
could get expensive. It was never meant for this kind of use: it was expected
that most views would be zero-asserts, so this wouldn't arise.
This also points at the solution: to define the target hook that tells the
compiler which insns are reset points, so that the compiler can use the
assembler .loc view support in the way it was designed to be used.
If insn lengths, as computed by gcc, are enough to determine whether or not an
insn takes up any code space, defining the reset_location_view target hook to
just return zero will do; otherwise, if more elaborate decisions are needed, it
may return 1 or -1 to override the length-based computation.

--- Comment #10 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
I forgot to mention, compiling with -ginternal-reset-location-views will issue
view resets where GCC would place them if the hook were defined so as to just
return zero, so we can easily confirm whether my guess as to the source of the
problem is correct, and whether insn lengths, as defined in GCC, are defined
correctly, at least as far as the current testcase goes.

Thanks! I was wondering if the patch also fixes the same thing for x86-64
(i.e., -m64); in which case we would have something like this:
__uint128_t func(__uint128_t a, unsigned shift)
{
return a << (shift & 63);
}

On it. At least in the x86_64 testcase in c3, the problem is that we have a
gomp function without line info, but with var loc bindings. The bindings end
up as locview lists referencing a view that is never emitted, because there's
no line info to attach it to.

--- Comment #11 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
FYI, the patch I'm working on for PR 84404 will add forced view resets at
function entry points, which should alleviate this somewhat, assuming there's
more than one function in the testcase.

Tentative patch

This patch caches affine_iv info before calling loop_version, and then uses
that cached info in canonicalize_loop_ivs. This fixes the ICE.

Yes this happens because the functions in <stdatomic.h> are defined as macros
which use the __atomic_xxx built-in functions, and they can operate on normal
non-atomic variables.

This is an issue with gcc 5.3.1
This is _not_ an issue with gcc 6.3.1 or gcc 7.3
I'm thinking this was addressed in the significant refactoring for bug #66653

Bug ID: 84497
Summary: link errors with trivial external thread_local
variables
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: P at draigBrady dot com
Target Milestone: ---
In some cases extern thread_local vars will generate a reference
to a tls_init function, when there is none generated for the translation unit
defining the variable, essentially due to it being std::is_trivial.
This used to work with gcc-5.3.1 and gcc-6.3.1,
the reason being that they were less efficient and
always exported the tls_init function, even for these std::is_trivial vars.
With gcc-7 the tls_init function is not emitted for these types,
but there is a mismatch in the logic determining if the extern thread_local
should call the tls_init function.
Specifically, in the module local to the var
if DECL_NONTRIVIALLY_INITIALIZED_P is false
then the tls_init function is not generated.
However in a translation unit that references such
an extern tls variable and TYPE_NEEDS_CONSTRUCTING is true
then a non weak call to the tls_init function is generated,
resulting in a link error.
$ cat a.cpp
#include <atomic>
struct Test { std::atomic<int> x; };
thread_local Test t;
$ cap main.cpp
#include <atomic>
struct Test { std::atomic<int> x; };
extern thread_local Test t;
int main() {
return t.x.load();
}
$ g++ -std=c++11 a.cpp main.cpp

--- Comment #28 from Martin Liška <marxin at gcc dot gnu.org> ---
(In reply to Martin Liška from comment #27)
> Let me decrypt how clang generates the red zones. I can probably quickly
> come up with a patch that will do the dynamic red zone size allocation.
> Having that you'll be able to rebuild kernel and catch remaining issues.
So the functions looks as follows:
static size_t VarAndRedzoneSize(size_t Size, size_t Granularity,
size_t Alignment) {
size_t Res = 0;
if (Size <= 4) Res = 16;
else if (Size <= 16) Res = 32;
else if (Size <= 128) Res = Size + 32;
else if (Size <= 512) Res = Size + 64;
else if (Size <= 4096) Res = Size + 128;
else Res = Size + 256;
return alignTo(std::max(Res, 2 * Granularity), Alignment);
}
It's bit confusing as it's size of variable plus red zone in shadow memory. So
to calculate just the size of redzone one has to subtract Size. And there's
some rounding up according to alignment.
I've prepared table with size of variable and corresponding middle end red zone
size:
+---------------+-----+------+---------+
| Variable size | GCC | LLVM | ratio |
+---------------+-----+------+---------+
| 1 | 63 | 15 | 23.81% |
| 4 | 60 | 12 | 20.00% |
| 8 | 56 | 24 | 42.86% |
| 12 | 52 | 20 | 38.46% |
| 16 | 48 | 16 | 33.33% |
| 32 | 32 | 32 | 100.00% |
| 40 | 56 | 40 | 71.43% |
| 50 | 46 | 46 | 100.00% |
| 64 | 32 | 32 | 100.00% |
| 96 | 32 | 32 | 100.00% |
| 128 | 32 | 32 | 100.00% |
| 129 | 63 | 79 | 125.40% |
| 196 | 60 | 76 | 126.67% |
| 256 | 32 | 64 | 200.00% |
| 257 | 63 | 79 | 125.40% |
| 511 | 33 | 65 | 196.97% |
| 512 | 32 | 64 | 200.00% |
| 1024 | 32 | 128 | 400.00% |
| 1025 | 63 | 143 | 226.98% |
| 2048 | 32 | 128 | 400.00% |
| 4096 | 32 | 128 | 400.00% |
| 8192 | 32 | 256 | 800.00% |
+---------------+-----+------+---------+
As seen (and mentioned by you), for small variables we have bigger red zones.

This looks like a duplicate of PR81116, fixed by r251125.
This is not a regression, and in genereal (we have played loose with
this rule) we are not supposed to backport.
Opinions?

--- Comment #1 from Romain Geissler <romain.geissler at amadeus dot com> ---
Hi,
I looked at the code. Actually all happens in tree-ssa-strlen.c, you have both
handle_builtin_stxncpy and maybe_diag_stxncpy_trunc. It happens that the logic
where you look at the next statement to check if its like "array[arraySize -1]
= '\0' is only implemented in maybe_diag_stxncpy_trunc. Somehow the very same
logic should be implemented in handle_builtin_stxncpy around line 2103 where
you throw this warning.
Cheers,
Romain

Bug ID: 84498
Summary: [nvptx, openacc] Don't generate state-propagation
inbetween subsequent worker/vector loops
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Consider a openacc parallel region with two subsequent worker loops, with no
code inbetween the two loops.
We have the following sequence of state transitions:
1. worker single
2. worker partitioned
3. worker single
4. worker partitioned
5. worker single
At the transition from worker single to worker partitioned (1 -> 2 and 3 -> 4),
we propagate the set of live registers from the worker single thread to all the
worker threads.
At the first transition, we need to propagate all registers, because they
haven't been initialized yet in all the workers.
At the second transition however, we only need to propagate the registers that
have been modified during 3. To do this on a per-register base is more
complicated, but if no code is executed during 3, then we know no register was
modified inbetween, and we can skip the propagation of all registers.

This is silent wrong code. IMO this should be back ported.

--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This applies to all diagnostics, not just -Wconversion:
class X {
X() : bad(1),
good(1)
{ }
void* bad;
int good;
};
i.cc: In constructor ‘X::X()’:
i.cc:3:11: error: invalid conversion from ‘int’ to ‘void*’ [-fpermissive]
good(1)
^
As Manu said, it's unlikely that the member name can be printed easily, because
the code that checks the initialization works with types, and the name of the
variable isn't known at that point. There are also dozens of different errors
and warnings that can happen there (not just -Wconversion) so they would all
need to be updated.
If the location was correct and shown with a range marking the variable that
would remove the need for printing the name:
i.cc: In constructor ‘X::X()’:
i.cc:2:11: error: invalid conversion from ‘int’ to ‘void*’ [-fpermissive]
X() : bad(1),
^~~~~~
I'm changing the priority from enhancement to normal, because printing the
wrong location is a bug.

Yes. That patch was applied. But that patch is only a support patch and not the
full patch to fix this. I was actually going to working on this again but it
won't go in until gcc 9.

Understood, but I would prefer to test the exact options that the build is
going to use.

Summary: Argument corruption when passing empty templated

Created attachment 43483

Minimal example
Hi,
we've discovered a strange problem when passing many function arguments where
one argument is an alias (using = ...) for a templated struct which has no
members (e.g. std::integer_sequence).
When building in non-optimized mode or with -O1/-O2, all arguments starting
from argument #7 seem to be corrupt. Building with -O3 seems to solve the
issue.
I've attached a small example program.
Correct output:
---------------
$ ~/gcc-8/bin/g++ -O3 -o repro repro.cpp && ./repro
0, 1, 2, 3, 4, 5, 6, 7
Wrong outputs:
--------------
$ ~/gcc-8/bin/g++ -O2 -o repro repro.cpp && ./repro
0, 1, 2, 3, 4, 5, 7, 0
$ ~/gcc-8/bin/g++ -O1 -o repro repro.cpp && ./repro
0, 1, 2, 3, 4, 5, 7, 0
$ ~/gcc-8/bin/g++ -O0 -o repro repro.cpp && ./repro
0, 1, 2, 3, 4, 5, 7, 2088590376
gcc version (freshly built):
----------------------------
$ ~/gcc-8/bin/g++ -v
Using built-in specs.

--- Comment #1 from patrick.schlangen at bmw dot de ---
Note: This problem does not happen with gcc 7.2.1.
The problem can also be reproduced with -O3 when the empty struct object passed
to the function is actually used in the function. (So it is not optimized out.)

Release Manager would probably say that it is up the Fortran
Maintainers on whether something should be backported. If I
have a patch on trunk that applies to the branch(es) with
minimum effort, I tend to backport to keep code in sync.

--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This is caused by -fabi-version=12 (which is the default for GCC 8). You can
get the old handling of empty structs with -fabi-version=11
The bug only seems to happen when the empty struct is a class template.
Reduced, this fails at -O0 but not any other optimization level, or with
-fabi-version=11:
template<typename T>
struct EmptyTemplatedStruct { };
using X = EmptyTemplatedStruct<int>;
void func(X, int a1, int a2, int a3, int a4, int a5, int a6, int a7, int a8)
{
if (a1 != 0)
__builtin_abort();
if (a2 != 1)
__builtin_abort();
if (a3 != 2)
__builtin_abort();
if (a4 != 3)
__builtin_abort();
if (a5 != 4)
__builtin_abort();
if (a6 != 5)
__builtin_abort();
if (a7 != 6)
__builtin_abort();
if (a8 != 7)
__builtin_abort();
}
int main()
{
func(X{}, 0, 1, 2, 3, 4, 5, 6, 7);
}

--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Can be reproduced also on x86_64-linux with -O3 -fno-tree-vectorize
-fno-ivopts.
For the latter, I wonder what's the point in using TARGET_MEM_REF in:
MEM[(long int *)p_28] = 0;
MEM[(long int *)p_28 + 8B] = 0;
MEM[(long int *)p_28 + 16B] = 0;
MEM[(long int *)p_28 + 24B] = 0;
MEM[(long int *)p_28 + 32B] = 0;
MEM[(long int *)p_28 + 40B] = 0;
MEM[(long int *)p_28 + 48B] = 0;
, isn't that something that MEM_REF can express too? store-merging doesn't
handle TARGET_MEM_REFs and only handles MEM_REFs. So, for stage1 shall it
handle also TARGET_MEM_REFs that only have base and optionally constant disp
and nothing else, or shall ivopts pass instead just generate MEM_REFs in those
cases?

In this similar case the C front end gets the location right, and also prints a
note with the name of the field:
#include <stddef.h>
struct X { int i; int j; };
struct X x = {
NULL,
2
};
$ gcc -Wall s.c -c

--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Because the C front end gets the location info right in recent versions of GCC
it also marks the bad initializer with carets:
bug.c:4:3: warning: initializer-string for array of chars is too long
"Christopher",
^~~~~~~~~~~~~
bug.c:4:3: note: (near initialization for 'sc_me.name')
bug.c:5:3: warning: initializer-string for array of chars is too long
"Yeleighton" };
^~~~~~~~~~~~
bug.c:5:3: note: (near initialization for 'sc_me.surname')
This is ideal, as it shows both the bad initializer, and the field it's trying
to initialize.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The bug is in the way we handle overlapping stores. The problem is that all we
do if there is overlap is:
if (IN_RANGE (info->bitpos, merged_store->start,
merged_store->start + merged_store->width - 1))
{
/* Only allow overlapping stores of constants. */
if (info->rhs_code == INTEGER_CST
&& merged_store->stores[0]->rhs_code == INTEGER_CST)
{
merged_store->merge_overlapping (info);
continue;
}
}
otherwise we:
/* |---store 1---| <gap> |---store 2---|.
Gap between stores or the rhs not compatible. Start a new group. */
/* Try to apply all the stores recorded for the group to determine
the bitpattern they write and discard it if that fails.
This will also reject single-store groups. */
if (!merged_store->apply_stores ())
delete merged_store;
else
m_merged_store_groups.safe_push (merged_store);
merged_store = new merged_store_group (info);
But the statements here are sorted primarily by bitpos and we emit statements
for the group at the location of the last statement (highest order) in the
merged store group. So I think we need to check before adding another store if
it is not rhs_code INTEGER_CST, whether there is any overlap with following
stores. Overlap is fine if the order of all the overlapping statements is
higher than MAX (merged_store->last_order, info->order), because then we know
we'll start a new group right after info and the merged stores of the current
group will come before any overlapping stores (whether merged successfully with
something or not), but otherwise we just shouldn't add info into the current
group.

Thanks for the test case. The root cause is the same as in bug 84474. The
warnings in both of these test cases are issued in gimple-fold.c (see
gimple_fold_builtin_strncpy), long before the code in tree-ssa-strlen.c has
run.
The difference between this case and the one in bug 84474 is that here the next
statement is already available. With that, I think there may be a way to avoid
the subset of the warnings in this report.

See also bug 82914 that points out cases where GCC silently ignores all
attributes, misspelled or otherwise. (It's a different problem than this one
and the solutions are different as well.)

Confirmed. I think the warning would be the most informative and the least
vague if it instead used the name of the array type, and also mentioned the
size of the initializer in case it's hidden behind a macro:
warning: initializer-string for an object of 'wchar_t[3]' has 5 elements
as long as there is a way to get at the name of the typedef. Otherwise,
printing the underlying type would be an alternative.

xemacs package starting with r254391
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
I'm still reducing the test-case, but with:
$ gcc -O2 -m32 alloc.i -funroll-loops -fdump-tree-optimized=/tmp/bad.txt -c -o
/tmp/bad.s -S -fno-strict-aliasing
I see following difference in tree-optimized dump:
$ diff -u /tmp/good.txt /tmp/bad.txt -U20

I suspect later 2 stores:
+ MEM[(void *)FFT_ptr_15] = 3735928389;
+ MEM[(unsigned int *)FFT_ptr_15 + 4B] = 3735928559;
which overwrite:
MEM[(struct Lisp_Free *)FFT_ptr_15].chain = marker_free_list.705_1;
It's probably connected with aliasing analysis that allows store motion after
the *.chain store.

--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
The warning on a2 is clearly bogus. ISTM we ought to get a warning on fd, but
don't because it's associated DECL_RTL is not set.
It almost feels like instead of walking over the variables in the blocks we
ought to iterate over the pseudos and check which of them map back to user
variables via REG_EXPR.
I'm going to re-open -- this is not entirely a duplicate of 21161 as there's a
missed warning here.

--- Comment #4 from Maxim Kuvyrkov <mkuvyrkov at gcc dot gnu.org> ---
Update from Charles:
===
When I tried to bootstrap the compiler with the patch, it failed because of
issues with -fPIC. I'm not sure it's worth pursuing the amount of work required
to resolve the -fPIC issue.

--- Comment #22 from Jeffrey A. Law <law at redhat dot com> ---
I don't think this is a duplicate of 21161.
AFAICT the core of the problem here is the multiple static assignments to the
pseudos holding cancel_arg and cancel_routine.
They set the objects to the same value, but the multiple-assignment nature is a
key aspect of the longjmp clobbering analysis.
I think the multiple assignment largely steps from the PHIs in this block:
;; basic block 5, loop depth 0, count 536656163 (estimated locally), maybe
hot
;; prev block 4, next block 6, flags: (NEW, REACHABLE, IRREDUCIBLE_LOOP,
VISITED)
;; pred: 4 [always (guessed)] count:268328082 (estimated locally)
(FALLTHRU,IRREDUCIBLE_LOOP,EXECUTABLE)
;; 6 [always (guessed)] count:1716613 (estimated locally)
(ABNORMAL,DFS_BACK,IRREDUCIBLE_LOOP,EXECUTABLE)
;; 3 [50.0% (guessed)] count:268328082 (estimated locally)
(IRREDUCIBLE_LOOP,FALSE_VALUE,EXECUTABLE)
# __cancel_routine_9(ab) = PHI <cleanup_fn(4), __cancel_routine_10(ab)(6),
cleanup_fn(3)>
# __cancel_arg_12(ab) = PHI <_1(4), __cancel_arg_13(ab)(6), _1(3)>
_24 = __sigsetjmp (&__cancel_buf.__cancel_jmp_buf, 0);
goto <bb 7>; [99.96%]
This happens in CCP1 and FRE1 for cancel_routine and cancel_arg respectively.
(replacinging a cancel_{arg,routine} with an equivalent). Once replaced, it's
exceedingly hard to undo. One could easily argue that we shouldn't to the
replacement in an abnormal PHI.
Regardless, this is separate from 21161. There is a slim chance that fixing
21161 is a requirement to fix this BZ, but they are not duplicates AFAICT.

--- Comment #6 from Manuel López-Ibáñez <lopezibanez at gmail dot com> ---
If I remember correctly, the problem here is constants and other
non-expression nodes don't have a location, so diagnostics use
input_location, which points to the end of the initializer. Something like
X+1 should work.
If so, David started fixing this problem, but this code may need fixes
similar to these: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00660.html
Otherwise, the problem is more insidious, and the nodes are probably built
with the wrong location.

Is there a reason this option doesn't extend to the C frontend? The same
problem with useless static_casts occurs with conventional C casts, too.

Summary|Dropped side effect with |Lost side effect when
|combination of statement |struct initializer
|expression and struct |expression uses comma
|initializer |operator
--- Comment #3 from Dave Pagan <dave.pagan at oracle dot com> ---
When emitting initializer elements (output_init_element), the left hand
expression of a comma operator with result size zero is not evaluated. It
should be, however, if the expression is marked as having side effects.

I can confirm https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84503#c3 fixes the
issue, thus it's dup.
Great work Jakub!

--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
(In reply to Ramana Radhakrishnan from comment #4)
Setting -march=armv7-a doesn't make a difference.
The root cause is that initializers of locally defined aggregates such as
struct { char a[N]; } S s = { "12345" };
are represented in one of two ways in GIMPLE:
a) as an assignment of the string to s.a, or
b) as a copy from a label (e.g., 's = *.LC0')
and the strlen pass only knows how to deal with (a) but not (b).
AFAICS, whether form (a) or form (b) is chosen depends on the size of the size
of the aggregate. Some targets use a lower threshold for (b) than others. As
far as I can see, x86_64 appears to cut over at 257 bytes, while arm-none-eabi
always uses (b).

It's the second part of the patch to resolve.c that offends. Clearly, the
possession of a iso_bind_c type component is the problem.
I will investigate more on Friday, when I have some time.

--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
(In reply to Martin Sebor from comment #5)
The cutoff between (a) and (b) also depends on whether or not a function is
being optimized for speed or for size, so at -Os, the x86_64 target also uses
(b) for all sizes.
Here's a test case and its output with an x86_64 compiler:
$ cat t.c && gcc -S -Wall -fdump-tree-optimized=/dev/stdout t.c
#pragma GCC optimize ("O2")
int f (void)
{
struct A { char a[4]; } a = { "123" };
return __builtin_strlen (a.a);
}
#pragma GCC optimize ("Os")
int g (void)
{
struct B { char b[4]; } b = { "123" };
return __builtin_strlen (b.b);
}
;; Function f (f, funcdef_no=0, decl_uid=1957, cgraph_uid=0, symbol_order=0)
__attribute__((optimize ("O2")))
f ()
{
<bb 2> [local count: 1073741825]:
return 3;
}
;; Function g (g, funcdef_no=1, decl_uid=1963, cgraph_uid=1, symbol_order=1)
__attribute__((optimize ("O2", "Os")))
g ()
{
struct B b;
long unsigned int _1;
int _4;
<bb 2> [local count: 1073741825]:
b.b = "123";
_1 = __builtin_strlen (&b.b);
_4 = (int) _1;
b ={v} {CLOBBER};
return _4;
}

This appears to be related to PR44290.
There is a fairly long discussion. The conclusion in that PR
suggests that you example is invalid. I'm not so sure that
is correct.
The EBNF in F2018, 10.2.2 to me seems to permit what
you are trying to do, but I don't use pointers so would
need to spend too much time unraveling the subtleties.

The error is present with with the top of trunk. The first revision that fails
to compile the code is r223301 (gcc 6.0.0). It refers to DR 1391 but I'm not
sure that the DR has a bearing on whether the test case is valid. Other
compilers including Clang, EDG, Intel ICC, and MSVC, successfully compile the
code so I'll confirm this report as valid on that basis.

--- Comment #5 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
(In reply to Martin Sebor from comment #0)
There are several issues conflated here.
> t.c: In function ‘f’:
> t.c:3:46: warning: signed and unsigned type in conditional expression
> [-Wsign-compare]
> unsigned char c = i ? (-__SCHAR_MAX__ - 1) : 1U;
This warning should be moved to where -Wsign-conversion is handled to avoid
emitting both.
The reason we cannot simply remove -Wsign-compare is because -Wsign-conversion
is not enabled by neither -Wall nor -Wextra, while -Wsign-compare is.
The reason -Wsign-conversion is not enabled by neither -Wall nor -Wextra is
because it has annoying false positives like PR40752. Clang doesn't have those.
> t.c:3:46: warning: negative integer implicitly converted to unsigned type
> [-Wsign-conversion]
This is same warning as Clang gives, just less informative than Clang's.
Printing the types should be easy.
> t.c:3:21: warning: conversion to ‘unsigned char’ alters ‘unsigned int’
> constant value [-Wconversion]
> unsigned char c = i ? (-__SCHAR_MAX__ - 1) : 1U;
This warning is a bug in my opinion. Probably the patch in PR40752 silences it.

--- Comment #4 from Sriram Swaminarayan <sriram at pobox dot com> ---
OK, I will admit that my knowledge here is pretty limited so if someone could
point out what I'm missing, I'd appreciate it.
On reading the other thread [PR45290] it appears it deals with pointers being
initialized with other pointers, be they procedure or data.
This compile error has to do with not being able to deal with a specific return
type for a function (i.e. those functions that return pointers). The return
type of a function should have no bearing on whether or not the initialization
should succeed.

This probably got fixed when early folding was fixed:
gcc 8.0 -Wsign-conversion -Wparentheses -Wall -Wextra -Wconversion gives:
<source>:3:48: warning: suggest parentheses around comparison in operand of '^'
[-Wparentheses]
unsigned short s = ~0x4578ADBCAA1DE677LL ^ a == 0;

unsigned short s = ~0x4578ADBCAA1DE677LL ^ a == 0;
~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~
The fix-it notes for -Wparentheses and having some warnings enabled by default
would be nice, but they are a different topic altogether.

Bug ID: 84506
Summary: INQUIRE(pos=) always sets pos=0 with
-fdefault-integer-8
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: albandil at atlas dot cz
Target Milestone: ---
INQUIRE(pos=...) seems to set 'pos' to zero when the unit number is 64bit
integer. This can be illustrated on the following example, which writes four
characters to a stream file and then INQUIRES position:
program TestInquire
implicit none
integer :: iUnit, iPos
open(newunit=iunit, file='output.txt', access='stream',
position='append', form='unformatted')
write(iUnit) 'TEXT'
inquire(iUnit, pos=iPos)
print *, iPos
end program TestInquire
The expected output is '5', which can be obtained by compilation using the
command
gfortran -ffree-form -std=f2008 inquire.f -o inquire
However, when the following command is used to compile the program, the output
is '0':
gfortran -ffree-form -std=f2008 inquire.f -o inquire -fdefault-integer-8
Both 4-byte and 8-byte mode produce '5' when Intel Fortran Compiler 17.0.1 is
used,
ifort -free -stand=f08 inquire.f -o inquire
ifort -free -stand=f08 inquire.f -o inquire -i8

--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
In 7.x this exact problem doesn't really exist, so the issue must be different
there.
I'd think it might be something fixable by PR82916 - like patch, but haven't
actually tried that yet.

Use
integer(4) :: iUnit, iPos
-fdefault-integer-8 converts iUnit and iPos to integer(8) while open and
inquire expect default integer, i.e., 4.
IMO this PR should be closed as INVALID.

--- Comment #3 from Steve Ellcey <sje at gcc dot gnu.org> ---
I tried digging into this some but was not able to come up with a fix.
I compared x86, which gives the expected error messages with aarch64
which gives different errors and tried to find out where they diverged.
I tracked it down to get_odr_type in ipa-devirt.c. Just before:
if (val->type != type
&& (!val->types_set || !val->types_set->add (type)))
I added this print statement:
fprintf(stderr,"%p %p %p\n", (void *) type, (void *) val->type, (void *)
val->types_set);
On x86 I see:
0x7f98aa018dc8 0x7f98aa018930 (nil)
0x7f98aa0189d8 0x7f98aa018d20 (nil)
0x7f98aa0189d8 0x7f98aa018d20 0x32c9610
0x7f0222cbfc78 0x7f0222cbf9d8 (nil)
0x7f0222cbfa80 0x7f0222cbfa80 (nil)
On Aarch64 I see:
0x4002c859aaa0 0x4002c859a758 (nil)
0x4002c859a6b0 0x4002c859a6b0 (nil)
0x4002c859a6b0 0x4002c859a6b0 (nil)
0x4001f45aa9f8 0x4001f45aa758 (nil)
0x4001f45aa800 0x4001f45aa800 (nil)
I think the second line where type and val->type are the same
for Aarch64 but not for x86 is where the problem is but I am not
sure why we have this difference.
I think it may be a bug in the odr hash function with an accidental
hash collision but I am not sure.

There isn't a problem with OPEN. The dump
(removing clutter) looks like
testinquire ()
{
integer(kind=8) ipos;
integer(kind=8) iunit;
{
struct __st_parameter_open open_parm.0;
integer(kind=4) newunit.1;
open_parm.0.newunit = &newunit.1;
_gfortran_st_open (&open_parm.0);
iunit = (integer(kind=8)) newunit.1;
}
Here open uses a INTEGER(4) internally and assigns
to the promoted INTEGER(8).
The INQUIRE is however broken for POS, which looks like
{
struct __st_parameter_inquire inquire_parm.3;
integer(kind=8) D.3764;
inquire_parm.3.strm_pos_out = &ipos;
inquire_parm.3.common.unit = (integer(kind=4)) iunit;
_gfortran_st_inquire (&inquire_parm.3);
}
}
inquire_parm.3.strm_pos_out is likely an INTEGER(4) and
gfortran is passing a pointer to an INTEGER(8) ipos.
At one point in time, there was a warning that
-fdefault-integer-8 changes the ABI and possibly
causes problems with libgfortran. I cannot find
the warning now. Documentation states
'-fdefault-integer-8'
Set the default integer and logical types to an
8 byte wide type.
which means gfortran should compile and execute
this code. In fact, gfortran appears broken.
From F03, 9.9.1, R930 has
inquire-spec is [ UNIT = ] file-unit-number
or POS = scalar-int-variable
Note that does not state scalar-default-int-variable.
Changing the original code to use INTEGER(8) instead of
using the -fdefault-integer-8 shows the same program.

--- Comment #3 from Steve Kargl <sgk at troutmask dot apl.washington.edu> ---
Upon closer inspection, gfortran's dump is correct
for both INTEGER and INTEGER(8) for
program TestInquire
integer :: iUnit, iPos
! integer(8) :: iUnit, iPos
open(newunit=iunit, file='output.txt', access='stream', status='replace')
write(iUnit) 'TEXT'
inquire(iUnit, pos=iPos)
print *, iPos
end program TestInquire
INTEGER gives 5 and INTEGER(8) gives 0.
Looks like a Jerry issue. :)

--- Comment #23 from Jeffrey A. Law <law at redhat dot com> ---
Note that if we fix the abnormal handler to target the block after the setjmp
rather than the setjmp itself all the problems magically disappear. That's
actually a more accurate CFG and arguably the right thing to do.
The concern is whether or not there are assumptions, particularly in the
gimple->rtl phase that fixing the CFG would break.

--- Comment #4 from Steve Kargl <sgk at troutmask dot apl.washington.edu> ---
The problem is related to UNIT.
program TestInquire
implicit none
integer(4) :: iUnit
integer(8) :: iPos
open(newunit=iunit, file='output.txt', access='stream', status='replace')
write(iUnit) 'TEXT'
inquire(iUnit, pos=iPos)
print *, iPos
end program TestInquire
The above gives the expected result.

It related to the automatic allocate of UNIT numbers with NEWUNIT.
If I do
iunit = 10
open(unit=iunit, file='output.txt', access='stream', status='replace')
One gets the right answer.
Looking in io/inquire.c, one has
void
st_inquire (st_parameter_inquire *iqp)
{
gfc_unit *u;
library_start (&iqp->common);
if ((iqp->common.flags & IOPARM_INQUIRE_HAS_FILE) == 0)
{
u = find_unit (iqp->common.unit);
inquire_via_unit (iqp, u);
}
(gdb) p iqp->common
$1 = {flags = 8192, unit = 10, filename = 0x4a6180 "d.f90", line = 9,
iomsg_len = 4806240, iomsg = 0x2008d0010 "", iostat = 0xc}
(gdb) p u
$2 = (gfc_unit *) 0x200ce6f00
Now with newunit.
(gdb) p iqp->common
$1 = {flags = 8192, unit = -3, filename = 0x4a6140 "d.f90", line = 9,
iomsg_len = 4806192, iomsg = 0x2008d0010 "", iostat = 0xc}
(gdb) p u
$2 = (gfc_unit *) 0x0
Whoops. u = 0x0, then runs into line 228-229.
if ((cf & IOPARM_INQUIRE_HAS_STRM_POS_OUT) != 0)
*iqp->strm_pos_out = (u != NULL) ? u->strm_pos : 0;
and there's your 0.

Target Milestone: ---
According to Intel
(https://software.intel.com/sites/landingpage/IntrinsicsGuide), there are no
alignment requirements for _mm_load_sd, _mm_store_sd and _mm_loaddup_pd. For
example, from _mm_load_sd:
Description
Load a double-precision (64-bit) floating-point element from
memory into the lower of dst, and zero the upper element.
mem_addr does not need to be aligned on any particular boundary.

__m128d is a tad bit cleaner. It does not require the casts.

--- Comment #7 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
The problem is not related to the newunit functions or neunit alloc stuff.
In the call to st_inquire we are passing the correct value of -10 for the unit
number. However, the dump-original we have:
{
struct __st_parameter_inquire inquire_parm.3;
integer(kind=8) D.3772;
inquire_parm.3.common.filename = &"pr84506.f90"[1]{lb: 1 sz: 1};
inquire_parm.3.common.line = 7;
inquire_parm.3.strm_pos_out = &ipos;
inquire_parm.3.common.flags = 8192;
inquire_parm.3.common.unit = (integer(kind=4)) iunit;
D.3772 = iunit;
if (D.3772 < 0 || D.3772 > 2147483647)
{
inquire_parm.3.common.unit = -3;
}
_gfortran_st_inquire (&inquire_parm.3);
}
The test is checking the range to be within a kind=4 integer limits and we are
passing -3 to the inquire statement.
The correct unit number is -10 as provided by newunit.

--- Comment #8 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
With iUnit as kind=4, the dump ford not have the check.
{
struct __st_parameter_inquire inquire_parm.2;
inquire_parm.2.common.filename = &"pr84506.f90"[1]{lb: 1 sz: 1};
inquire_parm.2.common.line = 7;
inquire_parm.2.strm_pos_out = &ipos;
inquire_parm.2.common.flags = 8192;
inquire_parm.2.common.unit = iunit;
_gfortran_st_inquire (&inquire_parm.2);
}
So we need to adjust the range check to include possible negative unit numbers.
In other words, change the test to:
if (D.3772 < -some-reasonable-value || D.3772 > 2147483647)
{
inquire_parm.3.common.unit = -3;
}
_gfortran_st_inquire (&inquire_parm.3);
It could be something like -32768 simply because the check is to make sure the
value used fits within kind=4 common.unit number.

Is the range check intended as a guard of inquiring on

--- Comment #11 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Tentative patch. Testing now. The intent originally was to prevent unit numbers
that don't fit into kind=4. It use to be we had no negative unit numbers. With
newunit, now we do.
I need to see if this patch allows any invalid code.

Summary: STOP and PAUSE statements with -fdefault-integer-8 and
large stop code
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: jb at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Consider the program
! compile with -fdefault-integer-8
program test
stop 12345678901
end program test
Compiling this with -fdefault-integer-8 and running it results in
STOP -539222987
This is because the value is larger than 2**31-1 and is typecasted to an
INTEGER(kind=4) before calling the stop function in libgfortran.
The same happens for the ERROR STOP and PAUSE statements as well.
(Not sure this is actually worth fixing since with -fdefault-integer-8 we're
throwing standards conformance out of the window anyway)

"The way _mm_load_sd is currently implemented in gcc, yes, sanitizers are right
to complain. Intel could have named the thing _mm_loadu_sd if that's what they
meant. It would be simple to change if we decide to do so, please file a PR in
bugzilla.
Workaround: define a typedef for double with __attribute__((__aligned__(1))),
and use _mm_set_sd(*(newtype*)p), that's how it will likely be done if we
change emmintrin.h."

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I don't see how this is related to sanitizer, sanitizer just checks what it
sees.
Say _mm_load_sd is implemented as
/* Create a vector with element 0 as *P and the rest zero. */
extern __inline __m128d __attribute__((__gnu_inline__, __always_inline__,
__artificial__))
_mm_load_sd (double const *__P)
{
return _mm_set_sd (*__P);
}
and so pedantically requires aligned load, it is like any other double *
dereference.
If these intrinsics really allow misaligned loads, then we need to use
something different, not sure if e.g.
struct S __attribute__((packed)) { double d; } const *p = (struct S const *)
(void *) __P;
return _mm_set_sd (p->d);
would be ok from aliasing POV or if we'd need to introduce a builtin to load a
potentially misaligned float or double. I guess the most important would be
that it doesn't slow down code.

I don't think we really support misaligned loads from non-aggregates, there
have been lengthy discussions about that in the past.

Is there any progress about it? It's blocking chromium build right now..

Bug ID: 84510
Summary: C front-end does not utilise -Wuseless-cast
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: bje at gcc dot gnu.org
Target Milestone: ---
The -Wuseless-cast option only applies to C++ and Objective C. It would also be
useful in the C front-end, particularly for finding 'do nothing' casts and
casts of literals, which the compiler can do itself by inferring the type of
the literal.

Started with r236615 and got fixed on the trunk with r253600.
Reduced testcase:
// PR c++/84496
// { dg-do compile { target c++14 } }
template <typename T, T n> struct C { static constexpr T D = n; };
struct E : C<bool, false> {};
template <typename> struct F : C<bool, false> {};
template <typename T> T foo ();
template <typename> struct H { typedef int G; };
template <typename> class I;
struct L;
template <typename, typename> struct J;
template <bool, bool, typename...> struct K;
struct R {
template <typename M, typename... N>
static J<decltype (foo<M> () (foo<N>...)), L> o;
};
template <typename P, typename... Q> struct K<false, false, P, Q...> : R {
typedef decltype (o<P, Q...>) G;
};
template <typename P, typename... Q>
struct D : K<E::D, F<typename H<P>::G>::D, P, Q...> {};
template <typename P, typename... Q> struct I<P (Q...)> : D<P, Q...> {};
template <typename> class function;
template <typename S, typename... Q> struct function<S (Q...)> {
template <typename T, typename = typename I<T (Q...)>::G> struct C;
template <typename, typename> using U = int;
template <typename P, typename = U<int, void>, typename = U<C<P>, void>>
function (P);
};
template <typename S, typename... Q>
template <typename P, typename, typename>
function<S (Q...)>::function (P)
{
}
void bar (function<void (int)>);
void
baz ()
{
auto a = [] {
static int counter;
bar ([] (auto) { counter++; });
};
}
Will commit the testcase to trunk now to make sure we don't regress it again.

We already use
typedef long long __m128i_u __attribute__ ((__vector_size__ (16),
__may_alias__, __aligned__ (1)));
_mm_loadu_si128 (__m128i_u const *__P)
{
return *__P;
}
So if that doesn't work, it needs fixing in a number of places...

Bug ID: 84511
Summary: Internal compiler error from directly printing return
of C_LOC
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: h.ratcliffe at warwick dot ac.uk
Target Milestone: ---
Created attachment 43487
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43487&action=edit
Tarball of 2-file working example
Directly printing return from C_LOC causes an internal compiler error if C_LOC
is called on a type defined in a module in a separate file. Capturing the
return and then printing succeeds.
Full error report is
f951: internal compiler error: Bad IO basetype (10)
0x5cbd3f gfc_internal_error(char const*, ...)
../../src/gcc/fortran/error.c:1348

Same error arises on gfortran 5.4 and 7.2.0 on Ubuntu and 6.3.0 on OSX, but
4.3.4 on SLES 11 (SP4) succeeds.
The error does not occur if module TWO defining the type is in the file where
C_LOC is called.

Any update on this, or any way I could help in getting this fixed?
It would be nice if we could finally switch OpenWrt to a more recent GCC
version soon.

--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This causes a regression for:
const char* err() { return "Error in "__FILE__; }
file.cc: In function ‘const char* err()’:
file.cc:1:28: error: unable to find string literal operator
‘operator""__FILE__’ with ‘const char [10]’, ‘long unsigned int’ arguments
const char* err() { return "Error in "__FILE__; }
^~~~~~~~~~~~~~~~~~~
With GCC 7 this gave a warning about not finding a literal operator, and then
continued as the author intended, i.e. concatenating the two strings.

Bug ID: 84513
Summary: gfortran -M generates circular dependency
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: eh.toussaint at gmail dot com
Target Milestone: ---
When using the -M option to let gfortran generate a rule for inclusion in
makefiles, the following code (all in one file) results in a circular
dependency for the .mod file.
$ cat foobar.f90
module bar
end module
program foo
use bar
end program
---end foobar.f90
$ gfortran -cpp -M foobar.f90
foobar.o bar.mod: foobar.f90 bar.mod
It's not a major problem, because (GNU) Make simply drops it with the following
message, but I'd still like to report it for the sake of neatness.
make: Circular bar.mod <- bar.mod dependency dropped.

There seem to be some missed opportunities reusing condition register over
extended asm (that does not clobber cc).

--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Is there a way to check if it's a pre-defined macro?
Or just change the condition to allow starting with two underscores, but not
allow starting with one (since user-defined UDLs must start with a single
underscore, and must not start with two).

--- Comment #3 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
I am working on this PR. The patch will be ready today or tomorrow.
The problem is that the move insn has one alternative with early clobber and
this move insn is processed on a fast path which ignores that other
alternatives might have no early clobbers.

Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: nsz at gcc dot gnu.org
Target Milestone: ---
i expected f1 and f2 to compile to the same code:
unsigned g;
void f1(unsigned count) {
unsigned i;
for (i = 0; i < count ; i++) g++;
}
void f2(unsigned count) {
unsigned i;
for (i = 0; i < count/2; i++) g++;
for ( ; i < count ; i++) g++;
}
but with -O3 the asm is
f1:
testl %edi, %edi
je .L1
addl %edi, g(%rip)
.L1:
ret
f2:
movl %edi, %eax
shrl %eax
je .L8
addl %eax, g(%rip)
.L8:
cmpl %eax, %edi
jbe .L7
subl %eax, %edi
addl %edi, g(%rip)
.L7:
ret
(on aarch64 even the address of g is recomputed for the second loop with adrp)

--- Comment #17 from Tom Tromey <tromey at gcc dot gnu.org> ---
The results in comment #13 seem to be missing some compilations --
I would have expected to see more files from libcpp in there.
As it is I only see directives.o and line-map.o.

Bug ID: 84516
Summary: bitfield temporaries > 32-bits have wrong type
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gnu at mllr dot cc
Target Milestone: ---
(Disclaimer: I'm not a compiler guy, so I may accidentally use the wrong
terminology)
Example: https://godbolt.org/g/brhTMw
#include <iostream>
struct A {
long x : 32;
long y : 33;
};
int main() {
A a;
std::cout << a.x; // OK
std::cout << a.y; // OK
std::cout << +a.x; // OK
std::cout << +a.y; // BREAKS on gcc
}
The problem is the last line. The type of the expression `+a.y` is 'long
int:33', which is not a type that operator<<() has an overload for. The type of
the expression `a.y` is 'long int' and so op<<() has an overload and works.
This issue seems to be affected by
(a) The size of the bit field; <= 32 bits works, > 32 bits breaks.
(b) Whether the bitfield is used in an expression producing a temporary;
>32-bit size AND a temporary breaks, <= 32-bit size and an lvalue works.
I confirmed this behavior on x86-64 gcc trunk using godbolt.org. (link again:
https://godbolt.org/g/brhTMw)

--- Comment #1 from Greg Miller <gnu at mllr dot cc> ---
The issue is not related to iostream. So, here's perhaps a simpler reproduction
example that may focus more on the issue at hand.
Link: https://godbolt.org/g/vA2rPN
struct A {
long x : 32;
long y : 33;
};
void F(int) {}
void F(long) {}
template <typename T>
void F(T) = delete;
int main() {
A a;
F(a.x); // Calls F(long)
F(+a.x); // Calls F(int)
F(a.y); // Calls F(long)
F(+a.y); // error: use of deleted function 'void F(T) [with T = long
int:33]'
}
Here we can see that the type of the expression `+a.y` is `long int:33`, which
I suspect is a problem. I think the type of that expression should be `long
int`.

This patch changes the libgfortran API for the PAUSE statement. By
passing a GFC_INTEGER_8 it handles -fdefault-integer-8, and for the
character version passing the length as a size_t.
Regtested on x86_64-pc-linux-gnu, committed as obvious.

Log:
PR 78534, 84509 Fix libgfortran API for PAUSE statement
This patch changes the libgfortran API for the PAUSE statement. By
passing a GFC_INTEGER_8 it handles -fdefault-integer-8, and for the
character version passing the length as a size_t.
Regtested on x86_64-pc-linux-gnu, committed as obvious.

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I guess this regressed with r253238 when these builtins were introduced.
I actually see multiple issues with these builtins:
1) as written above, lrintsfsi2 condition is TARGET_SF_FPR && TARGET_FPRND,
ditto lrintsfdi2 and lrintdfdi2 condition is TARGET_DF_FPR && TARGET_FPRND.
The builtins def file says just RS6000_BTM_HARD_FLOAT as the requirement, which
isn't enough, we also need TARGET_FPRND and for one of the builtins
TARGET_SF_FPR, for the other TARGET_DF_FPR. Changing
BU_FP_MISC_1 to require even (RS6000_BTM_HARD_FLOAT | RS6000_BTM_CELL)
doesn't work, then the builtin is refused on all CPUs but -mcpu=cell.
So, do we need to introduce two new RS6000_BTM_* values for these two builtins
and arrange for the right tests for them to be done?
2) with -mcpu=power6 or -mcpu=power7
long
f1 (float x)
{
return __builtin_fctid (x);
}
long
f2 (double x)
{
return __builtin_fctid (x);
}
int
f3 (float x)
{
return __builtin_fctiw (x);
}
int
f4 (double x)
{
return __builtin_fctiw (x);
}
ICEs in LRA instead:
pr83964.c: In function ‘f3’:
pr83964.c:24:1: error: unable to generate reloads for:
}
^
(insn 7 6 8 2 (set (reg:SI 124)
(unspec:SI [
(reg:DF 121 [ _1 ])
] UNSPEC_FCTIW)) "pr83964.c":23 419 {lrintsfsi2}
(expr_list:REG_DEAD (reg:DF 121 [ _1 ])
(nil)))
during RTL pass: reload
pr83964.c:24:1: internal compiler error: in curr_insn_transform, at
lra-constraints.c:3884
0xdc05c5 _fatal_insn(char const*, rtx_def const*, char const*, int, char
const*)
Either the rs6000 builtins expansion code for __builtin_fctiw float_truncate
the operand so that it is SFmode rather than DFmode, or it shouldn't use
lrintsf* code, but some other for an expander that adds the float_truncate.
What is the point of these builtins, i.e. what is the advantage of them over a
C cast from float or double to int or long?

Log:
i386: Add __x86_indirect_thunk_nt_reg for -fcf-protection -mcet
nocf_check attribute can be used with -fcf-protection -mcet to disable
control-flow check by adding NOTRACK prefix before indirect branch.
When -mindirect-branch=thunk-extern -mindirect-branch-register is added,
indirect branch via register, "notrack call/jmp reg", is converted to
call/jmp __x86_indirect_thunk_nt_reg
When running on machines with CET enabled, __x86_indirect_thunk_nt_reg
can be updated to
notrack jmp reg
at run-time to restore NOTRACK prefix in the original indirect branch.
Since we don't support -mindirect-branch=thunk-extern, CET and MPX at
the same time, -mindirect-branch=thunk-extern is disallowed with
-fcf-protection=branch and -fcheck-pointer-bounds.
Tested on i686 and x86-64.

Version: 8.0

Target Milestone: ---
const char* err() { return "Error in "__FILE__; }
With GCC 7 this gave a warning:
file.cc:1:28: warning: invalid suffix on literal; C++11 requires a space
between literal and string macro [-Wliteral-suffix]
const char* err() { return "Error in "__FILE__; }
^
But GCC 8 now rejects it:
file.cc: In function ‘const char* err()’:
file.cc:1:28: error: unable to find string literal operator
‘operator""__FILE__’ with ‘const char [10]’, ‘long unsigned int’ arguments
const char* err() { return "Error in "__FILE__; }
^~~~~~~~~~~~~~~~~~~
This was caused by r254443 for PR 80955
I'm not going to add the "rejects-valid" keyword, because technically the code
is invalid, but we accept it as an extension because there is no matching UDL.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Which means this really is not a regression.
If you replace the v[0] + v[1] + v[2] + v[3] part that is only accepted
starting from r186994, it will be accepts-invalid all the way to the
introduction of vector_size attribute.
The clang++ error looks bogus as well, there is no reason why I can't do:
template <class T>
int f (T x)
{
T __attribute__((vector_size (16))) v = { x };
v[0] += 1;
...
return v[0];
}
int x = f (5);
What doesn't work is that 1) we don't really have mangling for template
parameter with attributes on it 2) something else is broken for parameter
passing of these, e.g.
template <class T>
int f (T v __attribute__ ((vector_size (16))))
{
return 0;
}
int main ()
{
return f<int> ((int __attribute__ ((vector_size (16)))) { 1, 2, 3, 4} );
}
where we really don't need deduction fails too and 3) deduction doesn't work
with these. So, I think we should instead reject just what we can't support
and sorry about stuff we don't want to support right now.

I would like to really help you. But it's really problematic to have a mips
qemu machine with working network. Having that I would be able to run e.g.
https://people.debian.org/~aurel32/qemu/mips/
and I would be able to debug that locally. Any help how to play with?

Ah, I can reproduce with -mtune=silvermont or -mtune=atom, it works fine with
-mtune=generic or e.g. -mtune=silvermont -fno-vect-cost-model.
I'd just add -mtune=generic to the 2 test's dg-options.

Target Milestone: ---
In F2018 the STOP and ERROR STOP statements take and extra QUIET= specifier, a
logical value determining whether any information should be printed to the
screen or not.
For GCC 8, it would be good to have this in the library API even though the
parsing could well be postponed to a later release.

Also the new testcase for this bug has undefined behaviour. _ID is a reserved
name so the program cannot use it to define a macro or a UDL.

--- Comment #4 from Will Schmidt <willschm at gcc dot gnu.org> ---
Tried to re-create locally, I've gotten two ICE's using the provided testcode
snippet, neither look quite like the originally reported issue. (thus I don't
know if this is actually the same issue).
Neither of these require the -fgraphite-identity option be specified. -m32 or
-m64 doesn't seem to matter for me.

We actually do *not* need TARGET_FPRND; fctiw and fctid are ISA 1.xx insns.
Before power8 we do not allow putting SImode in FPRs.

The downstream bug report here:
https://bugzilla.redhat.com/show_bug.cgi?id=1545239
describes a problem seen on aarch64 with gcc 8 that breaks the build of Ruby at
-O1 and above.
Bisection shows that the problem started with r254815, which made
-fomit-frame-pointer the default.
Jakub reported:
> It is actually much older, I get the same crash if vm.c is compiled with
> -mlittle-endian -mabi=lp64 -g -grecord-gcc-switches -O1 -Wall -Werror=format-security
> -fexceptions -fPIC -fstack-protector -fno-strict-overflow -fexcess-precision=standard -fomit-frame-pointer

The issue is that the code generated for __builtin_longjmp reads a value for
x29 (the frame pointer) from the jmp_buf, but the code generated for
__builtin_setjmp doesn't actually write x29 to the jmp_buf, leading to
corruption of x29 when a longjmp occurs.
This corruption seems to be short-lived when -fno-omit-frame-pointer (the old
default), as every function restores x29 from the stack on exit.
With the new default of -fomit-frame-pointer the corruption can survive long
enough to cause crashes.
There's a lot more analysis at the downstream bug report in the URL above.
I'm about to attach a reproducer.
I'm marking this as "[8 Regression]" since although this is appears to be a
long-standing bug, the change of default in r254815 exposes it by default.

Created attachment 43489
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43489&action=edit
Reproducer
When compiled with:
gcc -DDUMP -g -O0 -fstack-protector-strong -Wall test.c
this runs to completion, and the x29 values show the function calls/returns:
x29 = 0x7ff2977910 : main : start of main
x29 = 0x7ff29778d0 : test_2 : start of test_2
x29 = 0x7ff29776a0 : test_1 : start of test_1
x29 = 0x7ff29776a0 : test_1 : zero return
x29 = 0x7ff2977690 : uses_longjmp : in uses_longjmp
x29 = 0x7ff2977740 : test_1 : non-zero return
x29 = 0x7ff2977690 : after_longjmp : after raise
x29 = 0x7ff2977740 : test_1 : end of test_1
x29 = 0x7ff29778d0 : test_2 : end of test_2
x29 = 0x7ff2977910 : main : end of main
On adding -fomit-frame-pointer, it crashes, and the x29 values show a
corruption after "uses_longjmp" which becomes a crash when the x29 value is
later used:
x29 = 0x7fff4709c0 : main : start of main
x29 = 0x7fff470960 : test_2 : start of test_2
x29 = 0x7fff470960 : test_1 : start of test_1
x29 = 0x7fff470960 : test_1 : zero return
x29 = 0x7fff470720 : uses_longjmp : in uses_longjmp
x29 = 0x7fff4707d0 : test_1 : non-zero return
x29 = 0x7fff4707d0 : after_longjmp : after raise
x29 = 0x7fff4707d0 : test_1 : end of test_1
x29 = 0x7fff4707d0 : test_2 : end of test_2

--- Comment #2 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> ---
It is a bug that we have changed to -fomit-frame-pointer by default for
AArch64. That changes a long standing ABI decision made at the dawn of the
port, and promised as a feature of the architecture. I would like to see this
fixed for GCC 8.
Ramana was testing a patch to fix this and change us back to
-fno-omit-frame-pointer, it (or someone else's patch achieving the same) would
be appreciated as the immediate fix for this issue.
I haven't validated the longer-term problem you mention with
-fomit-frame-pointer.
Ramana, can you pick this up and set us back to the appropriate default?
Otherwise, I can spin a patch. We should fix this urgently, or we miss the good
value that comes from whole-distribution testing.

--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It is the expand_member_init's current_template_parms check that matters here,
with
- if (current_template_parms
- || same_type_p (basetype, current_class_type))
- return basetype;
+ if (/* current_template_parms
+ || */same_type_p (basetype, current_class_type))
+ return basetype;
both testcases from this PR are properly rejected and no ICEs.
That breaks other stuff though, like:
/usr/src/gcc/obj/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/allocator.h:134:9:

To me any use of __builtin_setjmp/__builtin_longjmp is almost always incorrect.

--- Comment #12 from Jeffrey A. Law <law at redhat dot com> ---
I've got something that is working on most targets. I'm still refining a bit,
but I'm pretty confident we'll be able to fix in this cycle.
As expected scanning RTL from the setjmp point to figure out where the longjmp
will go (so that we can use the live-in set at the longjmp target rather than
the live set at the setjmp point) is a bit hairy.
It's almost certainly the case that the scanning is not going to work on all
targets. For example MIPS inserts an unspec sequence to fiddle the GOT after
the call and I really don't want to ignore an insn we don't understand. But
again, what I've currently got works on most targets and there's still some
refinements to do to improve coverage.

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Is the requirement just for functions that contain setjmp? If so, the backend
could just force frame pointers in cfun->calls_setjmp functions.
If not, even if the default is tweaked again to be -fno-omit-frame-pointer on
aarch64, the code is still wrong with explicit -fno-omit-frame-pointer, even
before that change.
The test uses __builtin_setjmp, can't reproduce it when using normal setjmp,
so is it just __builtin_setjmp that requires frame pointers? I think we don't
really have a flag about uses of __builtin_setjmp right now, but it could be
added next to calls_setjmp (calls_builtin_setjmp). Marking the function with
__builtin_setjmp with __attribute__((optimize ("no-omit-frame-pointer"))) fixes
it too.

count==1 might be the difficult case, since it's the only situation in which
the second loop does something but the first loop doesn't. But the code for:
void f2(unsigned count) {
unsigned i;
if (count <= 1) {
g += count;
} else {
for (i = 0; i < count/2; i++) g++;
for ( ; i < count ; i++) g++;
}
}
is also poor.

(completely untested) would require frame pointers for all setjmp calls, not
just __builtin_setjmp.
I agree pretty much all uses of __builtin_setjmp are a bug, but somebody needs
to explain it to the ruby authors. It is even weirder because they are using
the builtin with jmp_buf variable, jmp_buf is for the libc setjmp, for
__builtin_setjmp I think it is just void *buf[5]; or something similar.
BTW, does __builtin_return_address really work on aarch64 without frame
pointers? Various other targets require frame pointers when
cfun->machine->access_prev_frame (i.e. when SETUP_FRAME_ADDRESSES () has been
used).

That's the correct approach indeed, however aarch64_frame_pointer_required is
no longer used, this now needs to added to aarch64_layout_frame:
/* Force a frame chain for EH returns so the return address is at FP+8. */
cfun->machine->frame.emit_frame_chain
= frame_pointer_needed || crtl->calls_eh_return;
> BTW, does __builtin_return_address really work on aarch64 without frame

It only supports returning the return address of the current function (and even
that is most likely a bug rather than useful). When level != 0 it always
returns 0.

cfun->has_nonlocal_label instead of cfun->calls_setjmp would cover
__builtin_setjmp.
aarch64_frame_pointer_required would force frame_pointer_needed and thus be
true in that case too. But sure, if it works, we can change:
/* Force a frame chain for EH returns so the return address is at FP+8. */
cfun->machine->frame.emit_frame_chain
- = frame_pointer_needed || crtl->calls_eh_return;
+ = frame_pointer_needed || crtl->calls_eh_return ||

Note I'm not convinced this is sufficient. I tried compiling
testsuite/gcc.c-torture/execute/pr60003.c and it appears to mess up the frame
pointer so it no longer points to a frame chain:
baz:
adrp x1, .LANCHOR0
add x0, x1, :lo12:.LANCHOR0
stp x29, x30, [sp, -16]!
mov x29, sp
ldr x2, [x0, 8]
ldr x29, [x1, #:lo12:.LANCHOR0] // load of bad frame pointer
ldr x0, [x0, 16]
mov sp, x0
br x2
foo:
stp x29, x30, [sp, -176]!
adrp x2, .LANCHOR0
add x1, x2, :lo12:.LANCHOR0
mov x29, sp
add x3, sp, 176 // store of bad frame pointer
str x3, [x2, #:lo12:.LANCHOR0]
stp x19, x20, [sp, 16]
stp x21, x22, [sp, 32]
stp x23, x24, [sp, 48]
stp x25, x26, [sp, 64]
stp x27, x28, [sp, 80]
stp d8, d9, [sp, 96]
stp d10, d11, [sp, 112]
stp d12, d13, [sp, 128]
stp d14, d15, [sp, 144]
str w0, [sp, 172]
adrp x0, .L7
add x0, x0, :lo12:.L7
str x0, [x1, 8]
mov x0, sp
str x0, [x1, 16]
bl baz
.p2align 2
.L7:
ldr w0, [sp, 172]
ldp x19, x20, [sp, 16]
ldp x21, x22, [sp, 32]
ldp x23, x24, [sp, 48]
ldp x25, x26, [sp, 64]
ldp x27, x28, [sp, 80]
ldp d8, d9, [sp, 96]
ldp d10, d11, [sp, 112]
ldp d12, d13, [sp, 128]
ldp d14, d15, [sp, 144]
ldp x29, x30, [sp], 176
ret
What should happen is that it stores the actual sp/fp just before calling baz,
and baz then restores those before jumping to L7.

Bug ID: 84522
Summary: GCC does not generate cmpxchg16b when mcx16 is used
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: nruslan_devel at yahoo dot com
Target Milestone: ---
I looked up similar bugs, but I could not quite understand why it redirects to
libatomic when used with 128-bit cmpxchg in x86-64 even when '-mcx16' flag is
specified. Especially because similar cmpxchg8b for x86 (32-bit) is still used
without redirecting to libatomic.
80878 mentioned something about read-only memory, but that should only apply to
atomic_load, not atomic_compare_and_exchange. Right?
It is especially annoying because libatomic will not guarantee lock-freedom,
therefore, these functions become useless in many cases.
This compiler behavior is inconsistent with clang.
For instance, for the following code:
#include <stdatomic.h>
__uint128_t cmpxhg_weak(_Atomic(__uint128_t) * obj, __uint128_t * expected,
__uint128_t desired)
{
return atomic_compare_exchange_weak(obj, expected, desired);
}
GCC generates:
(gcc -std=c11 -mcx16 -Wall -O2 -S test.c)
cmpxhg_weak:
subq $8, %rsp
movl $5, %r9d
movl $5, %r8d
call __atomic_compare_exchange_16@PLT
xorl %edx, %edx
movzbl %al, %eax
addq $8, %rsp
ret
While clang/llvm generates the code which is obviously lock-free:
cmpxhg_weak: # @cmpxhg_weak
pushq %rbx
movq %rdx, %r8
movq (%rsi), %rax
movq 8(%rsi), %rdx
xorl %r9d, %r9d
movq %r8, %rbx
lock cmpxchg16b (%rdi)
sete %cl
je .LBB0_2
movq %rax, (%rsi)
movq %rdx, 8(%rsi)
.LBB0_2:
movb %cl, %r9b
xorl %edx, %edx
movq %r9, %rax
popq %rbx
retq
However, for 32-bit GCC still generates cmpxchg8b:
#include <stdatomic.h>
#include <inttypes.h>
uint64_t cmpxhg_weak(_Atomic(uint64_t) * obj, uint64_t * expected, uint64_t
desired)
{
return atomic_compare_exchange_weak(obj, expected, desired);
}
gcc -std=c11 -m32 -Wall -O2 -S test.c
cmpxhg_weak:
pushl %edi
pushl %esi
pushl %ebx
movl 20(%esp), %esi
movl 24(%esp), %ebx
movl 28(%esp), %ecx
movl 16(%esp), %edi
movl (%esi), %eax
movl 4(%esi), %edx
lock cmpxchg8b (%edi)
movl %edx, %ecx
movl %eax, %edx
sete %al
je .L2
movl %edx, (%esi)
movl %ecx, 4(%esi)
.L2:
popl %ebx
movzbl %al, %eax
xorl %edx, %edx
popl %esi
popl %edi

IIRC this was done because there is no atomic load/stores or a way to do
backwards compatible.

--- Comment #2 from Ruslan Nikolaev <nruslan_devel at yahoo dot com> ---
Yes, but not having atomic_load is far less an issue. Oftentimes, algorithms
that use 128-bit can simply use compare_and_exchange only (at least for
x86-64).

In other words, can atomic_load be redirected to libatomic while
compare_exchange still be generated directly (if -mcx16 is specified)?

--- Comment #6 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
The problem seems to be that gfc_conv_initalizer does not look
through
(gdb) p *expr
$1 = {expr_type = EXPR_STRUCTURE, ts = {type = BT_DERIVED, kind = 0,
to
(gdb) p *(expr->ts.u.derived->components->ts->u.derived)
$22 = {name = 0x7ffff7487080 "c_ptr", module = 0x7ffff7483410
"__iso_c_binding", declared_at = {nextc = 0x25672b8, lb = 0x2567280}, ts = {
type = BT_INTEGER, kind = 8, u = {derived = 0x256fc00, cl = 0x256fc00, pad
= 39255040}, interface = 0x0, is_c_interop = 1, is_iso_c = 1
It is, of course, open if it should need to... without adding the
vtab, gfc_conv_initializer does not even appear to be called.

I guess, in this case you would have to fall-back to lock-based implementation
for everything. But does C11 even require that atomic_load work on read-only
memory?

--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks for filing this report.
Confirmed. Both ICEs started with r253265.
The first ICE (testcase in comment #0) happens at line 446 of lambda.c in
build_capture_proxy here:
441 if (DECL_NORMAL_CAPTURE_P (member))
442 {
443 if (DECL_VLA_CAPTURE_P (member))
444 {
445 init = CONSTRUCTOR_ELT (init, 0)->value;
446 init = TREE_OPERAND (init, 0); // Strip ADDR_EXPR.
447 init = TREE_OPERAND (init, 0); // Strip ARRAY_REF.
448 }
where "init" is error_mark.
The second ICE (testcase in comment #1):
Happens at line 288 of lambda.c in is_normal_capture_proxy here:
288 gcc_assert (TREE_CODE (val) == COMPONENT_REF);
where val is a NOP_EXPR around a COMPONENT_REF (casting from T* to reference to
T[]).

--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
See also bug 70733, another bug with these types being user-exposed for
bit-fields for C++. For C++ (unlike C), the existence of these types
internally in the compiler should never be user-visible, because bit-field
width is explicitly not part of the type for C++.

These builtins were per a request from Steve Monroe. Not sure why he wanted

--- Comment #9 from Wilco <wilco at gcc dot gnu.org> ---
(In reply to Jakub Jelinek from comment #7)

Do non-local labels do the same odd thing? It seems to me if the mid-end
automatically inserts explicit writes to the frame pointer, it should also set
frame_pointer_needed. This may be a bug on other targets too.
Also a much better implementation would use a small landing pad in the function
that does the __builtin_setjmp (rather than inline it a different function), so
you avoid the frame pointer corruption. Eg.
baz:
...
ldr x1, [x0, 8]
br x1
L7_nonlocal: (landing pad in foo)
ldr x29, [x0, 16]
ldr sp, [x0]
b .L7
Or maybe we should get rid of these horrible hacks altogether?

Bug ID: 84524
Summary: -O3 causes behavior change
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: caleb.fujimori at gmail dot com
Target Milestone: ---
Created attachment 43491
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43491&action=edit
Preprocessed source
Compiling with -march=native -O3 causes an array initialization loop to fill
all elements with 61215. Disabling AVX512 with -mno-avx512f or -mno-avx512bw
creates the expected behavior.
Using built-in specs.

I think we should flip back fno-omit-frame-pointer on for gcc-8 as that breaks
the guarantee that we've had in the port for quite a while. I'm testing a patch
currently that I will get out first thing tomorrow to turn this back on.
If we want to turn it off that should be a conscious decision.

I think we should treat that as a separate but related issue.

The code is clearly incorrect even with the frame pointer is enabled, so this
has absolutely nothing to do with the frame pointer default. Like the eh_return
builtin, the implementation of these builtins is incorrect with or without a
frame pointer (and apparently has always been).

After more t(In reply to Andrew Pinski from comment #1)

After more thinking about it... Should not it be controlled by some flag
(similar to -mcx16 which enables cmpxchg16b)? This flag can basically say, that
atomic_load on 128-bit will not work on read-only memory. I think, it is better
than just unconditionally disabling lock-free implementation for 128-bit types
in C11 (which can is useful in a number of cases) just to accommodate some rare
cases when memory accesses must be read-only. That would also be more portable
and compatible with other compilers such as clang.

That testcase is invalid C, -fsanitize=undefined would even tell you.
__int128 requires 16-byte alignment and you're violating that.
You can use __int128 temp; memcpy (&temp, abc, sizeof (temp)); ... use temp ...
or __int128 in a __attribute__((packed)) structure etc. to read unaligned
objects.

--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Even when you find another PR for __builtin_longjmp (clearly RA related), that
doesn't mean that __builtin_{setjmp,longjmp} are totally broken and should not
be fixed on aarch64. As ruby (which for some cryptic reason has been using
those for quite some time) shows, it was working properly for years in
real-world cases, except on aarch64 with -fomit-frame-pointer. AFAIK this
issue is with __builtin_setjmp or what it is lowered into, not
__builtin_longjmp, so isn't really related to PR64242.
__builtin_setjmp/longjmp is described as saving/restoring fewer registers than
setjmp/longjmp but with the help of the prologue/epilogue of the frame
containing the __builtin_setjmp call. So if the help on aarch64 needs to be
frame pointer, let's add it, if it needs to be something else,
cfun->has_nonlocal_labels can be checked elsewhere too. Don't other non-local
gotos suffer a similar problem?

The fact that Ruby happen to work without crashes doesn't imply that
__builtin_longjmp/setjmp are 100% correct. The existing implementation breaks
the AArch64 ABI since it uses the frame pointer as an argument register. Using
the framepointer this way (broken frame chain) is explicitly disallowed by the
ABI. On x86 it can corrupt its own framepointer, but that's possible on other
targets too if you're unlucky.

Thanks for you explain.
It looks some weird to me.
If the type was int64_t or others, this can work.
Is there some specs to say that __int128 is 16-byte aligned?

No, it would be invalid too. It may appear to work.

Just check the __alignof__ (__int128) value?

Adjusted testcase for the testsuite:
void
foo (unsigned short *x)
{
unsigned short i, v;
unsigned char j;
for (i = 0; i < 256; i++)
{
v = i << 8;
for (j = 0; j < 8; j++)
if (v & 0x8000)
v = (v << 1) ^ 0x1021;
else
v = v << 1;
x[i] = v;
}
}
int
main (void)
{
unsigned short a[256];
foo (a);
for (int i = 0; i < 256; i++)
{
unsigned short v = i << 8;
for (int j = 0; j < 8; j++)
{
asm volatile ("" : "+r" (v));
if (v & 0x8000)
v = (v << 1) ^ 0x1021;
else
v = v << 1;
}
if (a[i] != v)
__builtin_abort ();
}
return 0;
}
I can confirm this is miscompiled even with current trunk at -O3 -mavx512bw.

Yes, you'er right.
Is there good way to assign value to unaligned int type except memcpy?

--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I wrote it above. memcpy or packed struct. And there is no reason to think
about memcpy as something inefficient, GCC will turn those single element
memcpy calls into efficient unaligned loads or stores.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
A side note, this shows how badly we need a type demotion pass, perhaps just on
the LOOP_VECTORIZED copy of loop before vectorization:
vect__27.7_175 = [vec_unpack_lo_expr] vect_v_16.5_173;
vect__27.7_176 = [vec_unpack_hi_expr] vect_v_16.5_173;
vect__28.8_177 = vect__27.7_175 << 1;
vect__28.8_178 = vect__27.7_176 << 1;
vect__29.9_179 = VEC_PACK_TRUNC_EXPR <vect__28.8_177, vect__28.8_178>;
or some match.pd patterns that will fix it after the vectorization. The above
is completely useless variant to just vector unsigned short << 1.

Log:
PR 84519 Handle optional QUIET specifier for STOP and ERROR STOP
Fortran 2018 adds a new QUIET specifier for the STOP and ERROR STOP
statements, in order to suppress the printing of signaling FP
exceptions and the stop code. This patch adds the necessary library
changes, but for now the new specifier is not parsed and the frontend
unconditionally adds a false value for the new argument.
Regtested on x86_64-pc-linux-gnu.

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It reproduces even with __attribute__((noipa)) on foo, so the problem is just
in that function. In assembly we can see:
vpsllw $8, %zmm6, %zmm5
addq $64, %rdi
vpmovzxwd %ymm5, %zmm0
vpcmpgtw %zmm5, %zmm2, %k1
vpslld $1, %zmm0, %zmm1
vextracti64x4 $0x1, %zmm5, %ymm0
vpmovzxwd %ymm0, %zmm0
vpslld $1, %zmm0, %zmm0
vpermt2w %zmm0, %zmm4, %zmm1
vpsllw $9, %zmm6, %zmm0
vpaddw %zmm7, %zmm6, %zmm6
vpxorq %zmm3, %zmm1, %zmm0
vpmovzxwd %ymm0, %zmm1
vpcmpgtw %zmm0, %zmm2, %k1
vpslld $1, %zmm1, %zmm5
vextracti64x4 $0x1, %zmm0, %ymm1
the compares into %k1 are useless, nothing really uses the %k1 afterwards, but
it should be used for conditional moves (the cond ? (v << 1) ^ 0x1021 : (v <<
9)
conditional moves). Looking into this.

Bug ID: 84527
Summary: missed optimization for special ternary operation
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ktietz at gcc dot gnu.org
Target Milestone: ---
The following sample:
int foo(int a, int b)
{
return a < b ? -1 : 1;
}
gets translated to
...
xorl %eax, %eax
cmpl %edx, %ecx
setge %al
leal -1(%rax,%rax), %eax
ret
...
There would be instead a better representation for such kind of patterns as
... cmpl %ecx, %edx
sbb %eax, %eax
orb $1, %al
ret
The missed patterns are 'result = COND ? -1 : VAL' and its permutations.
The same applies to the pattern 'result = COND ? VAL : 0' and its permuations,
which can be expressed as 'CMP a, b; SBB reg, reg; AND $VAL, reg;'

That hash would be from git://gcc.gnu.org/git/gcc.git
The SVN revision is r253252.
I asked on gcc-patches for a backport
(https://gcc.gnu.org/ml/gcc-patches/2018-02/msg00054.html)
I didn't get an explicit ok, but no objections either

For x86 we produce for sample:
movl 8(%esp), %eax
cmpl %eax, 4(%esp)
setge %al
movzbl %al, %eax
leal -1(%eax,%eax), %eax
ret
which could be expressed with one instruction less as
movl 4(%esp), %eax
cmpl %eax, 8(%esp)
sbbl %eax, %eax
orb $1, %al
ret

Summary: [8 Regression] gcc.c-torture/execute/960419-2.c -O3
fails with -fno-omit-frame-pointer
Product: gcc
Version: unknown

Haven't determined yet if this is related to PR 84521 but
gcc.c-torture/execute/960419-2.c fails when compiled with -O3
-fno-omit-frame-pointer whereas it didn't in GCC 7.
The good code from GCC 7 is:
main:
stp x29, x30, [sp, -48]!
add x29, sp, 0
add x0, x29, 20
stp xzr, xzr, [x0]
str xzr, [x29, 36]
ldr w0, [x29, 24]
cbnz w0, .L2
ldr w0, [x29, 28]

cbnz w0, .L2
ldr w0, [x29, 40]
cbnz w0, .L2

whereas the bad code from GCC 8 is:
main:
stp x29, x30, [sp, -48]!
mov x29, sp

We are about to turn fno-omit-frame-pointer back on for gcc-8 so this is
probably important.
Usually the RM's need to set this to P1 - so keeping this at P3 for an RM to
confirm this goes up to P1 or P2.

--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Slightly cleaned up testcase:
struct S { int a; char b[10]; } d;
__SIZE_TYPE__ s;
void
foo (void)
{
__builtin_strncpy (d.b, (char *) &d, s);
}
This code is a ticking bomb.
What is the base set builtin_memref::set_base_and_offset ?
Seems it is called with expr that is a pointer to something (i.e. arguments of
some strncpy-like function), but sometimes it sets base to the passed expr
(i.e. pointer to that memory), at other times to what it points to, at other
times to the get_inner_reference of what it points to. Without a clear
agreement of what it is obviously spots like the new:
tree basetype = TREE_TYPE (TREE_TYPE (dstref->base));
are wrong, because it doesn't know if base is the pointer pointing to something
(the TREE_TYPE (TREE_TYPE (dstref->base)) assumes that and assumes it is a
POINTER_TYPE_P), or not.
If you sometimes need the pointer and sometimes what it points to, then either
you should have a flag that determines what base is, or better use different
members for pointer and base of what it points to.
What is the TREE_OPERAND (expr, 0) in:
base = get_inner_reference (expr, &bitsize, &bitpos, &var_off,
&mode, &sign, &reverse, &vol);
poly_int64 bytepos = exact_div (bitpos, BITS_PER_UNIT);
HOST_WIDE_INT const_off;
if (!base || !bytepos.is_constant (&const_off))
{
base = get_base_address (TREE_OPERAND (expr, 0));
return;
}
doing? It doesn't seem you've checked what expr actually is before using
TREE_OPERAND (expr, 0) on it. The cases that fall through into this code are
either that expr is an operand of ADDR_EXPR, or SSA_NAME, or in theory some
constant. I don't think get_inner_reference ever returns NULL though.

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Indeed:
int f1 (int a, int b) { return a < b ? -1 : 1; }
int f2 (unsigned a, unsigned b) { return a < b ? -1 : 1; }
unsigned f3 (int a, int b) { return a < b ? -1 : 1; }
unsigned f4 (unsigned a, unsigned b) { return a < b ? -1 : 1; }
shows that we emit the code you want to see for f2 and f4, but that just means
it is not the right code for f1 and f3.

--- Comment #4 from Tiziano Müller <dev-zero at gentoo dot org> ---
There is an even simpler reproducer and slightly different twist, but I suspect
it's the same bug:
test.c:
void bar();
int main(int argc, char* argv[]) {
bar();
return 0;
}
works as expected with any version with gcc and the following Fortran file:
foo_c_standalone.f90:
module foo_c
use iso_c_binding
contains
subroutine bar()
write(*,*) "bar"
end
subroutine c_bar() bind(C, name="bar")
write(*,*) "c_bar"
call bar()
end
end module
while it terminates with a segfault due to the recursive call with gcc-5.3.1,
gcc-7.3.0 (and probably also gcc-4.9+) but works with gcc-4.8.5 with the
following code instead:
foo_c.f90:
module foo_c
use iso_c_binding
use foo
contains
subroutine c_bar() bind(C, name="bar")
write(*,*) "c_bar"
call bar()
end
end module
foo.f90:
module foo
contains
subroutine bar()
write(*,*) "bar"
end
end

But the machine is mips64:

GNU/Linux
Is it a target where I can reproduce the issue? Which --target option do you
use for a cross-compiler?

Changing that (__)? to ((__GI_)?__)? is preapproved if it works.
Those are just glibc internal aliases which are in the symbol table too though,
so if you have full debug info for libpthread.so rather than just what .dynsym
contains it is possible you get it instead.

Can't reproduce even before the revision, I must have the setup somehow broken.
But the package now builds, so it's fixed.

Bug ID: 84529
Summary: INQUIRE fails on "recycled" internal units
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libfortran
Assignee: unassigned at gcc dot gnu.org
Reporter: albandil at atlas dot cz
Target Milestone: ---
The following program fails with the error "Inquire statement identifies an
internal file" at the call to INQUIRE.
program TestRecycleInternalUnit
implicit none
integer :: iunit, ipos
character(len=10) :: sstream
write(sstream,'(I0)') 12345
print *, 'sstream = ', sstream
open(newunit=iunit, file='output.bin', access="stream", form="unformatted")
inquire(iunit,pos=ipos)
print *, 'n = ', ipos
close(iunit)
end program TestRecycleInternalUnit
I looked into the code of libgfortran/io/open.c (and around) and it seems that
OPEN reuses the cached internal unit (-10 in this case) used for writing to
string. However, the member "internal_unit_kind" of the unit structure is not
reset to 0 in the "st_open" function. This makes the subsequent INQUIRE think
that its argument is an internal unit.

Bah, this'll be https://gcc.gnu.org/ml/gcc-patches/2017-11/msg02061.html . I
hadn't realised that the -fomit-frame-pointer handling was the reason it was no
longer a problem.

Fixed on trunk. Does this actually fail on GCC 7? The regexp there should
work AFAICS.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
My understanding is that this is because cand->fn in this case (the B ctor) is
not DECL_DELETED_FN, but strip_inheriting_ctors (cand->fn) is, we somehow
haven't tried to instantiate it (bailed early) and when we get into
convert_default_arg, we try it with the non-instantiated A(T, T = 0) rather
than
with A(T, T = 0) [with T = int]. Returning error_mark_node from
convert_default_arg in that case doesn't work though, because the bug is not
diagnosed at all.

It fails on 7 (and always has). The fix for PR79455 needs to be applied before
this one can be.

Summary: c/c++: bogus warning for functions with different
argument lengths but compatible arguments
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: siddhesh at gotplt dot org
Target Milestone: ---
gcc trunk throws a bogus warning about incompatible function cast when the cast
target and the function have different argument lengths but the same arguments
for the common subset. An example of this is the PyCFunction <->
PyCFunctionWithKeywords cast in python.
Patch posted along with test case:

Right, that produced code depends on the sign of the condition arguments seems
to be pretty wrong

No, signed comparison is very different from unsigned comparison, and only
unsigned comparison < is usable for this. Borrow flag reflects unsigned signed
comparison result rather than signed.

--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
The affected bit of code assumes dstref->base is an array and doesn't check to
see if it's something else. In both of these cases it's a VAR_DECL so
TREE_TYPE (TREE_TYPE (dstref->base)) returns null.

This bit was left over from the previous version that used
get_addr_base_and_unit_offset() where the function can return null. If
get_inner_reference() cannot return null and if the byte offset is guaranteed
to be constant the code can be removed. (I made the change based on your
suggestion in bug 84095 and asked you to review it multiple times before I
committed it.)

get_inner_reference can't return NULL, just see what it does. bytepos in
theory could be non-constant on aarch64 with SVE, still, what do you know about
expr that you think you can safely use the operand of it (it couldn't have
one).
Why don't you treat non-constant bytepos as var_off? Why do you think var_off
must be non-negative? Perhaps if base is a DECL in correct programs it should
be, but if base is a MEM_REF it can be anything.
And again for if (TREE_CODE (base) == MEM_REF) you set base = TREE_OPERAND
(base, 0);, so what used to be at that point the base of the reference becomes
its address; though if base is instead say a DECL_P or something even
different, you don't do that.

Moved Power 8 vec_float2, vec_signed2 and vec_unsigned2 builtin tests to new
file builtins-3-runnable-p8.c. Fixed ICE for vec_signed2 and vec_unsigned2
which were found in builtins-3-runnable.c once the vec_float2 test was moved to
a P8 test file. Commit 257937.

Bug ID: 84532
Summary: [7/8 Regression] std::thread::__make_invoker
prematurely unwraps reference_wrappers
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: rs2740 at gmail dot com
Target Milestone: ---
std::thread::__make_invoker uses make_tuple, which unwraps reference_wrappers,
so instead of passing a DECAY_COPY'd reference_wrapper<T> rvalue to __invoke,
it (incorrectly) passes a T lvalue instead.
This means that we accept invalid code like
int i = 0;
std::thread t([](auto&){}, std::ref(i));
It's not too hard to come up with code that changes meaning and valid code that
gets rejected either.
This is a 7/8 regression: previously the now-removed __bind_simple was used,
which correctly just does a simple decay.

--- Comment #12 from Paul Thomas <pault at gcc dot gnu.org> ---
The original regression is now fixed. The testcases of comments 2 and 7 have
been fixed on trunk but remain on 6- and 7-branches. I will await advice from
the list as to whether to backport or not and so will keep the PR open.
Neil, you were right about the common origin. Thanks for the report.

Modifying line 33 to
if (allocated (rc% spots(k)% vm)) print *, "hello"
it appears that it is the test that fails for me (on a 32-bit system).
I tried to compare the dump-tree-original of 8-trunk to 7.2, but
failed to understand the differences, which are probably due to the
changes in array descriptors.

--- Comment #5 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Looking at the tree dump we have:
_gfortran_st_write (&dt_parm.0);
{
struct Pdtfoo_1 * D.3772;
D.3772 = &x;
_gfortran_transfer_integer_write (&dt_parm.0, &D.3772->k1, 4);
_gfortran_transfer_integer_write (&dt_parm.0, &D.3772->l1, 4);
_gfortran_transfer_integer_write (&dt_parm.0, &D.3772->n, 4);
}
_gfortran_st_write_done (&dt_parm.0);
And so in trans-io.c I am going to try:
diff --git a/gcc/fortran/trans-io.c b/gcc/fortran/trans-io.c
index 36adb034475..d492ed8cc4e 100644
--- a/gcc/fortran/trans-io.c
+++ b/gcc/fortran/trans-io.c

- transfer_expr (se, &c->ts, tmp, code, NULL_TREE);
+ if (c->attr.pdt_kind == 0 && c->attr.pdt_len == 0)
+ transfer_expr (se, &c->ts, tmp, code, NULL_TREE);
/* Reset so that the pdt string length does not propagate

Its not clear to me yet why printing x%n is coming out zero however. I will
explore some more.

#include <thread>
int main()
{
static_assert(!std::is_constructible<std::thread, std::thread, int>::value,
"");
}
This assertion fails. The standard requires the constructor to not participate
in overload resolution when the first argument is a std::thread.

--- Comment #5 from Harald Anlauf <anlauf at gmx dot de> ---
The code in comment#0 compiles with current trunk. The ICE is gone.
Not sure if the code is valid, but NAG accepts it
without complaining.
Adding a line
print *, a
prints
1 2
which I think is correct.

--- Comment #1 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
With a slightly modified testcase (namespace std instead of N) I get
a different stack-trace:

template<int> struct A {};
}
std::template A<> a;
===============================

Bug ID: 84538
Summary: Array of derived type elements incorrectly accessed in
function
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: abensonca at gmail dot com
Target Milestone: ---
The following code results in incorrect behavior with gfortran 8.0.1 (r257956):
module bugMod
public
type :: t
integer :: i
end type t
type, extends(t) :: te
integer :: j
end type te
contains
subroutine check(n)
implicit none
class(t), intent(inout), dimension(:) :: n
write (0,*) "FROM MODULE ",n%i
return
end subroutine check
end module bugMod
program bug
use bugMod
class(t), allocatable, dimension(:) :: n
allocate(te :: n(2))
n(1:2)%i=[8,3]
write (0,*) "FROM PROGRAM ",n%i
call check(n)
end program bug
$ gfortran -v
Using built-in specs.
COLLECT_GCC=gfortran
COLLECT_LTO_WRAPPER=/nfs/home/abenson/Galacticus/Tools/libexec/gcc/x86_64-pc-linux-gnu/8.0.1/lto-wrapper
Target: x86_64-pc-linux-gnu
Configured with: ../gcc/configure --prefix=/nfs/home/abenson/Galacticus/Tools
--enable-languages=c,c++,fortran --disable-multilib
Thread model: posix
gcc version 8.0.1 20180223 (experimental) (GCC)
$ gfortran bug.F90
$ a.out
FROM PROGRAM 8 3
FROM MODULE 8 0
I would expect the output to be the same from the module subroutine as from the
main program.

--- Comment #1 from Neil Carlson <neil.n.carlson at gmail dot com> ---
And same example but using character data. This compiles but gives a segfault
when run at the assignment statement.
class(*), allocatable :: x(:)
x = ['foo','bar']
select type (x)
type is (character(*))
if (any(x /= ['foo','bar'])) stop 1
end select
end

--- Comment #4 from Neil Carlson <neil.n.carlson at gmail dot com> ---
Note that if the sourced allocation in the comment 0 test case
allocate(x%v,source=['foo','bar'])
is replaced by the equivalent (I think) assignment
x%v = ['foo','bar']
Then the code produces a run time segfault instead:
$ gfortran --version
GNU Fortran (GCC) 8.0.1 20180224 (experimental)
$ gfortran -g -fbacktrace bug.f90
$ ./a.out
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 0x7f3c46fda94f in ???
#1 0x0 in ???
Segmentation fault (core dumped)
I think the problems here may be related to the simpler test cases in PR84539
which I just reported.

--- Comment #1 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
The suggested wild-card function type for functions taking 2 or more parameters
would be something like this:
PyObject * (*) (PyObject *, PyObject *, ...);
It is still necessary to cast it back to the correct type before calling.

--- Comment #2 from Paul Thomas <pault at gcc dot gnu.org> ---
Hi Andrew,
The testcase gives the same result if 'n' in the main program is a pointer.
However, if the dummy is given the allocatable/pointer attribute, as
appropriate, then the correct result is obtained.
Otherwise, using select type works correctly too.
Please use either of these as a temporary workaround.
I am hunting for where the dummy attribute has been missed in testing for the
need for pointer arithmetic in accessing the array elements.
Thanks for reporting this.
Paul

--- Comment #6 from Romain Geissler <romain.geissler at amadeus dot com> ---
Hi,
Tried to apply this patch on top of current trunk. During my build process, I
bootstrap a complete Linux/binutils/glibc/gcc toolchain following the Linux
From Scratch guidelines.
Without the patch, the bootstrap works fine. With the patch, the bootstrap
fails when using a newly built gcc 8, I try to build the Linux headers. Here
are the logs I have:
+ cd /workdir/src/linux-2.6.32.23
+ make mrproper
+ make INSTALL_HDR_PATH=dest headers_install
CHK include/linux/version.h
UPD include/linux/version.h
HOSTCC scripts/basic/fixdep
HOSTCC scripts/basic/docproc
HOSTCC scripts/basic/hash
HOSTCC scripts/unifdef
In file included from
/home/jenkins/workspace/OTF_Toolchain_release_4.0-YQJ6EBM33XTPWHNNQSFSZFEGBOIWUEOX32S2OZLINN43UBSUZTJA/output/build/temporary-system/install/include/string.h:630,
from scripts/unifdef.c:72:
scripts/unifdef.c: In function 'Mpass':
scripts/unifdef.c:377:28: internal compiler error: Segmentation fault
static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); }
^~~~~~~
scripts/unifdef.c:377:28: internal compiler error: Aborted
gcc: internal compiler error: Aborted signal terminated program cc1
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
scripts/Makefile.host:118: recipe for target 'scripts/unifdef' failed
make[1]: *** [scripts/unifdef] Error 4
Makefile:1089: recipe for target '__headers' failed
make: *** [__headers] Error 2
I expect that you would be able to reproduce the same error by downloading the
Linux headers
(https://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.32.23.tar.gz) and then:
make mrproper
make INSTALL_HDR_PATH=dest headers_install
This file is actually pretty simple. See
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/scripts/unifdef.c?h=v2.6.32.23#n377
...
static void Pelif (void) { print(); ignoreoff(); state(IS_PASS_MIDDLE); }
...
static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); }
...
Maybe the fact that the instruction that follows strncpy is a function call
makes gcc seg faults ?
Cheers,
Romain

--- Comment #6 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
The patch fixes the first part of the problem so the write will ignore the kind
and len parameters.
The component n is simply not being initialized at all. I am searching code for
where this ought to happen. I was thinking possibly in build_struct in decl.c,
but I am not sure yet.

the kernel file that GCC faults on?

Bug ID: 84542
Summary: missing -Wdeprecated-declarations on a redeclared
function template
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
Redeclaring an ordinary function with the deprecated attribute makes the
attribute effective on subsequent uses of the function.
However, redeclaring a function template with the same attribute has no effect
(regardless of whether the template has been defined).
$ cat a.C && gcc -S -Wall a.C
void f ();
void __attribute__ ((deprecated)) f ();
void ff ()
{
f (); // -Wdeprecated-declarations (good)
}
template <class T>
void g ();
template <class T>
void __attribute__ ((deprecated)) g ();
void gg ()
{
g<void>(); // missing warning
}
template <class T>
void __attribute__ ((deprecated)) g () { }
void ggg ()
{
g<void>(); // missing warning
}
a.C: In function ‘void ff()’:
a.C:7:6: warning: ‘void f()’ is deprecated [-Wdeprecated-declarations]
f (); // -Wdeprecated-declarations (good)
^
a.C:3:35: note: declared here

This never worked correctly in GCC so it's not a regression. It works as
expected in Clang and ICC, and with [[deprecated]] also in MSVC.

I stumbled across this problem while reducing an actual error to a minimal test
case (PR84539). I wasn't going to bother reporting it (it seems a bit too
silly) but reconsidered. Maybe this means something significant to a developer;
I'll let you decide.
$ cat bug.f90
class(*), allocatable :: x
x = 42
end
$ gfortran bug.f90
/tmp/cclHGRhz.o:(.rodata+0x60): undefined reference to `__copy_INTEGER_4_.3788'
collect2: error: ld returned 1 exit status
And similar with a real or character value, and presumably with any of the
kinds that gfortran supports. The link error goes away if you add a TYPE IS
clause for the type of the value; e.g.
class(*), allocatable :: x
x = 42
select type (x)
type is (integer)
end select
end

--- Comment #11 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
At the place where the ICE happens:
gcc_checking_assert (precision == x.get_precision ());
(gdb) p precision
$1 = 64
(gdb) p x
$2 = (const generic_wide_int<wide_int_storage> &) @0x7fffffffca10:
{<wide_int_storage> = {val = {-1, 140737340585456, 140737340585456}, len = 1,
precision = 32}, static is_sign_extended = <optimized out>}
Looking up the call chain, the following can be found:
gimple_simplify_174 (res_code=0x7fffffffcbcc, res_ops=0x7fffffffcbd0,
type=0x7ffff7168b28, captures=0x7fffffffcad0, cmp=EQ_EXPR,
valueize=0xad6320 <no_follow_ssa_edges(tree_node*)>, seq=0x7fffffffcd18) at
gimple-match.c:7605
so it can be assumed that the type of a comparison goes wrong.
Hmm... there is no difference visible in the tree dumps. However,
there is the line
if (x->_vptr->_hash == 64409183)
in the dump. Maybe the types on the left and right hand sides do
not agree?

--- Comment #12 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
_hash is an integer(4) in all cases:
$ gfortran -fdefault-integer-8 -fdump-fortran-original a.f90 2>/dev/null |
grep hash
(_hash (INTEGER 4) () PRIVATE)
(_hash (INTEGER 4) () PRIVATE)
$ gfortran -fdump-fortran-original a.f90 2>/dev/null | grep hash
(_hash (INTEGER 4) () PRIVATE)
(_hash (INTEGER 4) () PRIVATE)
Probably the constant has the wrong type.

Note that compiling with trunk
type keyword
character(60), allocatable :: c(:) ! works but should it?
end type keyword
...
allocate(character(80) :: kw(1)%c(10))
gives the error
allocate(character(80) :: kw(1)%c(10))
1
Error: Allocating kw at (1) with type-spec requires the same character-length
parameter as in the declaration
> I think that the is now fixed and can be closed.
Agreed, closing.

The opening sentence was incorrect. The *_sd functions do not have alignment
requirements. Searching through the Intrinsic Guide reveals the following
functions do not have the alignment requirements:
* _mm_load_sd
* _mm_store_sd
* _mm_load_ss
* _mm_loadh_pi
* _mm_loadl_pd
* _mm_loadl_pi
* _mm_loadu_pd
* _mm_loadu_ps
* _mm_loadu_si128
* _mm_store_sd
* _mm_store_ss
* _mm_storeu_pd
* _mm_storeu_ps
* _mm_storeu_si128
All the functions listed above specifically state "mem_addr does not need to be
aligned on any particular boundary."
The remaining functions have natural alignment or 16-byte alignment
requirements.

--- Comment #4 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Just to clarify. Are you saying that this: invalid
type t(a)
integer, len :: a
character(len=a) :: c
end type
should be: valid
type t(a)
integer, len :: a = 2
character(len=a) :: c
end type
a is a parameter and c is a component.
?
Some of the I/O touches on pr84143.

No, both of those are valid. The constraint is on component initialization, and
type parameters are *not* components. So something like this would be invalid
by F08:C458
type t(a)
integer, len :: a
character(len=a) :: c = 'foo'
end type

--- Comment #5 from Paul Thomas <pault at gcc dot gnu.org> ---
The if statement is generating the code:
struct array01_t_spot D.3815;
if ((real(kind=4)[0:] * restrict) ((struct t_spot *)
(rc->spots.data + (sizetype) ((rc->spots.offset + SAVE_EXPR <(integer(kind=8))
k> * rc->spots.dim[0].stride) * D.3815.span)))->vm.data != 0B)
You will see that D.3815's span is being used but is never set.
This temporary is being generated at trans-array.c:3664. It should produce an
assignment of the array descriptor to the temporary, as well as the
declaration.
Somewhere, the se->pre is not being retained so that the assignment disappears.
I am onto it.

Thanks, I can reproduce it with that test case. Checking for the basic block
being null fixes the SEGV for me. Let me retest this and post an update for
review.

Forgot to say that the ICE requires a compiler configured with
--enable-checking=yes.

Great! Also, another interesting case (with the same idea for -m64 and
__uint128_t) would be this:
gcc -m32 -Wall -O2 -S test.c
unsigned func(unsigned long long a, unsigned shift)
{
return (unsigned) (a >> (shift & 31));
}
In this case, clang generates just a single 'shrd' instruction.

Bug ID: 84544
Summary: Missing warning when returning a reference to internal
variable inside a lambda
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jpakkane at gmail dot com
Target Milestone: ---
Suppose you have a C++14 method like this:
auto f1() {
int x = 3;
auto l = [&]() -> int& { return x; };
return l;
}
Here the returned lambda contains a reference to the stack allocated integer
that goes out of scope. Gcc does not give a warning for this. If you call
function f1 like this:
int& f2() {
auto l = f1();
return l();
}
Then Gcc does print the following warning (but only with -O2 or higher):
<source>: In function 'int& f2()':
<source>:9:14: warning: function returns address of local variable
[-Wreturn-local-addr]
return l();
^
<source>:2:9: note: declared here
int x = 3;
^
Compiler returned: 0
It would be useful if gcc generated a warning for f1 already.

use any_vector_type
implicit none
class(*), allocatable :: x
character(*), parameter :: vec(*) = ['foo','bar']
allocate(x, source=any_vector(vec))
select type (x)
type is (any_vector)
select type (xvec => x%vec)

--- Comment #2 from Siddhesh Poyarekar <siddhesh at gotplt dot org> ---
There's also a PyCFunctionWithoutArgs that takes just one parameter so it'll
have to be one arg onwards but I don't know the impact on it's API. I'm going
to test that when I get back home tonight and propose a fix in Python. I kinda
understand the rationale behind not diluting the warning, but I'd like to keep
this open pending conclusion of the discussion on the ML.

Bug ID: 84547
Summary: Suboptimal code for masked shifts (ARM64)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: nruslan_devel at yahoo dot com
Target Milestone: ---
Partially related to the Bug 84431 (see description of the problem there) but
observed on ARM64 instead of x86/x86-64. (Not sure about ARM32.)
Test example:
__uint128_t func(__uint128_t a, unsigned shift)
{
return a << (shift & 63);
}
aarch64-linux-gnu-gcc-7 -Wall -O2 -S test.c
GCC generates:
func:
and w2, w2, 63
mov w4, 63
sub w5, w4, w2
lsr x4, x0, 1
sub w3, w2, #64
lsl x1, x1, x2
cmp w3, 0
lsr x4, x4, x5
orr x1, x4, x1
lsl x4, x0, x3
lsl x0, x0, x2
csel x1, x4, x1, ge
csel x0, x0, xzr, lt
ret
While clang/llvm generates better code:
func: // @func
// BB#0:
and w8, w2, #0x3f
lsr x9, x0, #1
eor x11, x8, #0x3f
lsl x10, x1, x8
lsr x9, x9, x11
orr x1, x10, x9
lsl x0, x0, x8
ret
Another interesting case when __builtin_unreachable() is used:
__uint128_t func(__uint128_t a, unsigned shift)
{
if (shift > 63)
__builtin_unreachable();
return a << shift;
}
But in this case, neither clang/llvm, nor gcc seem to be able to optimize code
well.

--- Comment #3 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
Actually the warning on PyCFunctionWithoutArgs
is _not_ a false positive:
I am looking at Python-3.6.1 right now.
What I see is that functions with no arguments
have the signature "PyObject * (*)(PyObject *)"
but on the call side the Call passes two arguments
see Python-3.6.1/Objects/methodobject.c:
case METH_NOARGS:
size = PyTuple_GET_SIZE(args);
if (size != 0) {
PyErr_Format(PyExc_TypeError,
"%.200s() takes no arguments (%zd given)",
f->m_ml->ml_name, size);
return NULL;
}
res = (*meth)(self, NULL);

Bug ID: 84550
Summary: [8 Regression] stepping through gcc does not work with
gdb 8.0.1
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: tkoenig at gcc dot gnu.org
Target Milestone: ---
Not sure if this is a gdb or a gcc problem.
With gdb 8.0.1, stepping through functions after breakpoints is often
broken. This makes it hard to debug gcc itself.
Example:
ig25@linux-d6cw:/tmp> cat a.f90
type foo
integer n
end type
type bar
type(foo) array(2)
end type
type(bar) b
associate (n_array => b%array%n)
end associate
end
ig25@linux-d6cw:/tmp> gdb ~/Gcc/trunk-bin/gcc/f951

This is a rather old regression, r247548 already has it.

--- Comment #4 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
Also these look like more like invalid casts than bogus warnings:
../Python-3.6.1/Objects/frameobject.c:586:5: Warnung: cast between incompatible
function types from »void (*)(PyFrameObject *)« {alias »void (*)(struct _fra
me *)«} to »int (*)(PyObject *)« {alias »int (*)(struct _object *)«}
[-Wcast-function-type]
(inquiry)frame_tp_clear, /* tp_clear */
^
../Python-3.6.1/Objects/funcobject.c:408:18: Warnung: cast between incompatible
function types from »PyObject * (*)(PyFunctionObject *)« {alias »struct _obj
ect * (*)(struct <anonym> *)«} to »PyObject * (*)(PyObject *, void *)« {alias
»struct _object * (*)(struct _object *, void *)«} [-Wcast-function-type]
{"__code__", (getter)func_get_code, (setter)func_set_code},
^
../Python-3.6.1/Objects/funcobject.c:408:41: Warnung: cast between incompatible
function types from »int (*)(PyFunctionObject *, PyObject *)« {alias »int (*
)(struct <anonym> *, struct _object *)«} to »int (*)(PyObject *, PyObject *,
void *)« {alias »int (*)(struct _object *, struct _object *, void *)«} [-Wcast-
function-type]
{"__code__", (getter)func_get_code, (setter)func_set_code},
^
And unfortunately the last two would be suppressed by the proposed patch.

--- Comment #7 from Paul Thomas <pault at gcc dot gnu.org> ---
Quite why this testcase worked before revision r257065 I cannot for the life of
me understand.
The line trans-array.c:3664
decl = gfc_evaluate_now (se->expr, &se->pre);
was never being added to the function pre block and so the pointer span was in
principle not available.
Anyway, this rather trivial patch fixes the problem.
Thanks for the report.
Paul

--- Comment #8 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
For the record:
> Caused by revision r257065.

Actually I think this was exposed by r257065 but caused by r251949.
The following variant is OK with r251946
program gfcbug148
implicit none
type t_spot
real, allocatable :: vm(:,:,:)
end type t_spot
type t_rowcol
integer :: nh
type(t_spot), pointer :: spots(:) =>NULL()
end type t_rowcol
type(t_rowcol) :: col
call construct (col, 80)
call destruct (col)
print *, "OK"
!========================================================================
contains
!========================================================================
subroutine construct (rc, nh)
type(t_rowcol) ,intent(out) :: rc ! row or column to set
integer ,intent(in) :: nh ! number of spots in a row
rc% nh = nh
allocate (rc% spots (nh))
end subroutine construct
!------------------------------------------------------------------------
subroutine destruct (rc)
type(t_rowcol) ,intent(inout) :: rc ! row or column to free
integer :: k
if (associated (rc% spots)) then
print *, "### destruct: size(rc% spots)=", size(rc% spots)
if (size(rc% spots) > 1) then
print *, "### destruct: allocated (vm) =", allocated(rc%spots(1)%vm)
end if
print *, size(rc% spots)
do k=1, size(rc% spots)
print *, k, allocated (rc% spots(k)% vm)
end do
print *, "before deallocate"
endif
nullify (rc% spots)
end subroutine destruct
end program gfcbug148
but gives with r251980
### destruct: size(rc% spots)= 80
### destruct: allocated (vm) = F
80
1 F
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
when compiled with -fsanitize=undefined.

-fno-caller-saves -fno-plt -msoft-float
remquo.c: In function 'remquo':

Most targets check if -falign-* is already set before messing with it at -Os.

On the original test case, it generates this code:

400690: 8c830008 lw v1,8(a0)
400694: 24020001 li v0,1

4006a0: 8c830000 lw v1,0(a0)

4006a8: 28630002 slti v1,v1,2
4006ac: 1060000a beqz v1,4006d8 <mytest+0x48>

4006b8: 00000000 nop

4006cc: 00000000 nop
4006d0: 0045102b sltu v0,v0,a1
4006d4: 00021023 negu v0,v0
4006d8: 03e00008 jr ra

4006e4: 2402ffff li v0,-1
4006e8: 03e00008 jr ra
4006ec: 24020001 li v0,1
It looks to me like it's generating lots of useless nop instructions after lw

Never mind, it seems that gcc 5.5 is doing that as well. I will run some more

r241528 fails, r241527 does not, so rr241528 it is.

From pr64273:
Tobias Burnus 2014-12-11 16:29:56 UTC
Follow up to PR44054 and PR53552. See also related bugs PR28662, PR62226,
PR53934.
There are two possibilities, either to use a real
#pragma warning
or to make it more Fortran-like and use
!GCC$ warning directive
See PR44054 and PR53552.

Yuck!-(I think there are a lot of really more important things to do. In any
case choose the latter).

Yes, the nops are preexisting and counter-measures for pipeline hazards, but I
don't know the MIPS port enough to say much more than that.

--- Comment #11 from Romain Geissler <romain.geissler at amadeus dot com> ---
Hi,
Indeed this version of the patch doesn't have any segv. However it seems that
it doesn't fix anymore the initial bug report. Does it actually passes the new
tests you introduced in your patch ?
Unless I am mistaken (I am pretty sure I have applied the patch), the following
code extracted from your tests still emit a warning with -O2
<<EOF
#define strncpy __builtin_strncpy
struct A
{
char a[4];
};
void succ (struct A *p, const struct A *q)
{
/* Verify that the assignment suppresses the warning for the conditional
strcnpy call. The conditional should be folded to true since the
address of an array can never be null (see bug 84470). */
if (q->a)
strncpy (p->a, q->a, sizeof p->a - 1); /* { dg-bogus
"\\\[-Wstringop-truncation" } */
p->a[sizeof p->a - 1] = 0;
}
EOF

relocations.
collect2: error: ld returned 1 exit status
Used version:
binutils-2.30 (older 2.29 is also affected), gcc-HEAD (older 6.4.0 is also
affected)
I'm not sure who exactly is at fault here: gcc or binutils.
What happens here is:
'const struct e' (with .text pointer) is placed into '.rodata' by gcc and
later is merged into '.text'.
What I suspect should happen:
'const struct e' (with .text pointer) is placed into '.data.rel.ro' by gcc
and later is merged into '.data'?

==============
ERROR! The versions of gmp.h (5.0.5) and libgmp (4.3.1) do not match.
The possible causes are:
* A bad configuration in your include/library search paths.
* An inconsistency in the include/library search paths of
your development environment; an example:
http://gcc.gnu.org/ml/gcc-help/2010-11/msg00359.html
* GMP has been upgraded after the first "make check".
In such a case, try again after a "make clean".
* A new or non-standard version naming is used in GMP.
In this case, a patch may already be available on the
MPFR web site. Otherwise please report the problem.
In the first two cases, this may lead to errors, in particular with MPFR.
If some other tests fail, please solve that problem first.

Summary: strncpy warnings (and friends) are not ignorable with
pragmas when inlined
Product: gcc
Version: 8.0.1

Severity: normal

Hi,
I have hit this case today. Let's consider that for any reason, you have a
wrapper around strncpy (and friends). Then it looks like that #pragma diagnotic
that are used around the call site of the wrapper are ignored in -O2 when gcc
does some inlining.
Example (built with -Wall -Werror -Wextra -O2):
<<EOF
char* strncpy_wrapper(char* dest, const char* source, int size)
{
return __builtin_strncpy(dest, source, size);
}
void f()
{
char buff[3];
# pragma GCC diagnostic push
# pragma GCC diagnostic ignored "-Wstringop-truncation"
strncpy_wrapper(buff, "123", 3);
# pragma GCC diagnostic pop
}
EOF
Of course, here this is a degenerate example. But in real code, this kind of
cases might happen, you know what you want to do, and want to ignore gcc errors
just for specific cases, but you can't.
Cheers,
Romain

This example emits:
error: ‘char* __builtin_strncpy(char*, const char*, long unsigned int)’ output
truncated before terminating nul copying 3 bytes from a string of the same
length [-Werror=stringop-truncation]
return __builtin_strncpy(dest, source, size);
~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~
cc1plus: all warnings being treated as errors
while one would expect that no warning is emitted here.

--- Comment #12 from Martin Sebor <msebor at gcc dot gnu.org> ---
Yes, all the relevant tests pass with the patch. There is no warning for
either the test case in comment #0 or the one in comment #11. The change from
v1 of the patch is just the addition of test for null to avoid the ICE.

Confirmed with 8.0, 7.4, and 6.4 regardless of optimization or similar options.
I'm not sure what revision introduced the ICE but based on bisection it
doesn't seem the code was ever accepted. It needs to be reduced to a smaller
test case to tell for sure.

--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can confirm this doesn't work as you would expect. Unfortunately, the
problem isn't limited to just -Wstringop-truncation but affects many if not all
middle-end warnings. Here's another example with -Wformat-truncation.
-Wnonnull has the same problem.
$ cat b.c && gcc -O2 -S -Wall b.c
void g (char *d, unsigned n, const char *s, int i)
{
__builtin_snprintf (d, n, "%s-%i", s, i);
}
char a[8], b[8];
void h (int i)
{
#pragma GCC diagnostic ignored "-Wformat-truncation"
g (a, sizeof a, b, i);
}
b.c: In function ‘h’:
b.c:3:33: warning: ‘%i’ directive output may be truncated writing between 1 and
11 bytes into a region of size between 0 and 7 [-Wformat-truncation=]
__builtin_snprintf (d, n, "%s-%i", s, i);
^~
b.c:3:3: note: ‘__builtin_snprintf’ output between 3 and 20 bytes into a
destination of size 8
__builtin_snprintf (d, n, "%s-%i", s, i);

Bug ID: 84561
Summary: -Wstrinop-truncation with -O2 depends on strncpy's
size type
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization

Target Milestone: ---
Hi,
There is another -Wformat-truncation that I don't understand with -O2. It looks
like I may or may not get the warning if the inlined size type used in strncpy
is 32 bits or 64 bits, and really can't figure out why that even matters wrt
warnings. Reproducer built with -Wall -Wextra -Werror -O2 on x86_64:
<<EOF
typedef unsigned long size_t;
template <size_t N> class String
{
public:
String();
void set(const char* string, size_t len = N)
{
if (len > N)
{
len = N;
}
__builtin_strncpy(_string, string, len);
_string[len] = 0;
}
private:
char _string[N + 1];
};
class A
{
public:
A() {}
void setStringSize_t(const char* string, size_t len)
{
_string.set(string, len);
}
void setStringUnsignedInt(const char* string, unsigned int len)
{
_string.set(string, len);
}
private:
String<3> _string;
};
class B
{
public:
B() {}
A& getA()
{
return _a;
}
private:
A _a;
};
void f(A& a)
{
a.setStringUnsignedInt("123", 3); //No warning here.
a.setStringSize_t("123", 3); //No warning here.
}
void f(B& b)
{
b.getA().setStringUnsignedInt("123", 3); // Unexpected warning here.
b.getA().setStringSize_t("123", 3); // No warning here.
}
EOF
I am getting this error/warning:
error: ‘char* __builtin_strncpy(char*, const char*, long unsigned int)’ output
truncated before terminating nul copying 3 bytes from a string of the same
length [-Werror=stringop-truncation]
__builtin_strncpy(_string, string, len);
~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
As you can see, using either "size_t" or "unsigned int" for parameter "len"
seems to influence the gcc warning, despite everything is fully inlined. Is
this expected ?
Cheers,
Romain

Just a note. I'm tracking a separate problem with delay slot filling that
looks like it's related to handling of debug insns. I doubt it's the same
problem, but if you stumble over it, be aware I'm testing a fix.

Created attachment 43501
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43501&action=edit
minimal example for both cases (int and array-of-char*)
(Minimal test case attached as source tar.gz, as the problem is inherently
multi-compilation-unit and doesn't involve any headers. Snippets below for
illustration.)
Compiling the following code with -c -O2...
__attribute__((weak)) const int y = 0;
void foo(void) {
for (i = 0; i < y; i++) {
write(2, "X", 1);
}
}
yields an empty foo() even though 'y' is weak (which I consider a bug, as
linking with another unit with a proper symbol 'y' with nonzero value will Do
The Wrong Thing and not even issue a warning - -fsanitize=undefined cannot help
either, as the whole loop is optimized away).
In a similar case, having
__attribute__((weak)) const char *arr[] = { NULL };
[...]
for (i = 0; arr[i]; i++) {
in one unit and overriding 'arr' in another with
const char *arr[] = { "abc", "def", NULL };
causes related problems: this time the loop doesn't disappear completely, so
-fsanitize=undefined complains about illegal array accesses - but I don't
believe this is justified, unless the different implicit array size is illegal
by the C standard; I couldn't find anything on that.
Tested with Debian gcc7 (7.3.0) and gcc8 (8.0.1) on x86_64, thus assigning to
the latest version.

--- Comment #13 from Romain Geissler <romain.geissler at amadeus dot com> ---
Hi,
It looks like that the code in #comment 11 works when you build just with -O2,
but not when you add debug symbols: -O2 -g. Do we have a way to ignore debug
statements when looking for the next statement in the next basic block ?
Cheers,
Romain

Summary: GCC interpretation of C11 atomics (DR 459)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: nruslan_devel at yahoo dot com
Target Milestone: ---
I know, there are related issues already but decided to open a new issue
because it primarily relates to the interpretation of DR 459 by GCC and
response from C11/WG14.
(I also posted the same on the mailing list.)
I have read multiple bug reports (Bug 84522, Bug 80878, Bug 70490), and a past
decision regarding GCC change to redirect double-width (128-bit) atomics for
x86-64 and arm64 to libatomic. Below I mention major concerns as well as the
response from C11 (WG14) regarding DR 459 which, most likely, triggered this
change in more recent GCC releases in the first place.
If I understand correctly, the redirection to libatomic was made for 2 reasons:
1. cmpxchg16b is not available on early amd64 processors. (However, mcx16 flag
already specifies that you use CPUs that have this instruction, so it should
not be a concern when the flag is specified.)
2. atomic_load on read-only memory. DR 459 now requires to have 'const'
qualifiers for atomic_load which probably resulted in the interpretation that
read-only memory must be supported. However, per response from C11/WG14 (see
below), it does not seem to be the case at all. Therefore, previously filed Bug
70490 does not seem to be valid.
There are several concerns with current GCC behavior:
1. Not consistent with clang/llvm which completely supports double-width
atomics for arm32, arm64, x86 and x86-64 making it possible to write portable
code (w/o specific extensions or assembly code) across all these architectures
(which is finally possible with C11!).
The behavior of clang: if mxc16 is specified, cmpxchg16b is generated for
x86-64 (without any calls to libatomic), otherwise -- redirection to libatomic.
For arm64, ldaxp/staxp are always generated. In my opinion, this is very
logical and non-confusing.
2. Oftentimes you want to have strict guarantees (by specifying mcx16 flag for
x86-64) that the generated code is lock-free, otherwise it is useless.
Double-width atomics are often used in lock-free algorithms that use tags
(stamps) for pointers to resolve the ABA problem. So, it is very useful to have
corresponding support in the compiler.
3. The behavior is inconsistent even within GCC. Older (and more limited, less
portable, etc) __sync builtins still use cmpxchg16b directly, newer __atomic
and C11 -- do not. Moreover, __sync builtins are probably less suitable for
arm/arm64.
4. atomic_load can be implemented using read-modify-write as it is the only
option for x86-64 and arm64 (see below).
For these reasons, it may be a good idea if GCC folks reconsider past decision.
And just to clarify: if mcx16 (x86-64) is not specified during compilation, it
is totally OK to redirect to libatomic, and there make the final decision if
target CPU supports a given instruction or not. But if it is specified, it
makes sense for performance reasons and lock-freedom guarantees to always
generate it directly.

Response from the WG14 (C11) Convener regarding DR 459: (I asked for a
permission to publish this response here.)
-----------------------------
Ruslan,
Thank you for your comments. There is no normative requirement that const
objects be suitable for read-only memory. An example and a footnote refer to
read-only memory as a way to illustrate a point, but examples and footnotes are
not normative. The actual nature of read-only memory and how it can be used
are outside the scope of the standard, so there is nothing to prevent
atomic_load from being implemented as a read-modify-write operation.
David
------------------------------
My original email:
----------------------
Dear David Keaton,
After reviewing the proposed change DR 459 for C11: http://www.open-std.org/
jtc1/sc22/wg14/www/docs/ summary.htm#dr_459 ,
I identified that adding const qualifier to atomic_load (C11 implements its
without it) may actually be harmful in some cases.
Particularly, for double-width (128-bit) atomics found in x86-64 (cmpxchg16b
instruction), arm64 (ldaxp/staxp instructions), it is currently only possible
to implement atomic_load for 128 bit using corresponding read-modify-write
instructions (i.e., potentially rewriting memory with the same value, but, in
essence, not changing it). But these implementations will not work on read-only
memory. Similar concerns apply to some extent to x86 and arm32 for double-width
(64-bit) atomics. Otherwise, there is no obstacle to implement all C11 atomics
for corresponding types in these architectures. Moreover, a well-known
clang/llvm compiler already implements all double-width operations for x86,
x86-64, arm32 and arm64 (atomic_load is implemented using corresponding
read-modify-write instructions). Double-width atomics are often used in data
structures that need tagging for pointers to avoid the ABA problem (e.g., in
lock-free stacks and queues).
It is my understanding that C11 aimed to make atomics more or less portable
across different microarchitectures, while at the same time provide an ability
for a compiler to optimize code well and utilize all potential of the
corresponding microarchitecture.
If now it is required to support read-only memory (i.e., const qualifier) for
atomic_load, 128-bit atomics are likely be impossible to implement in any
meaningful and portable way. Thus, anyone who wants to use them will have to go
with assembly fallbacks (or compiler extensions), thus, partially defeating the
purpose of C11 atomics. One way to address this concern would be to state that
atomic_load on read-only memory is implementation-defined and may not be
supported for all types. That would also mean to go with the previous C11
definition (i.e., without the const qualifier) to implement atomic_load rather
than what was proposed in the DR 459 change.
I am ready to submit a more formal proposal if this is something that can be
considered by the committee.

(In reply to Martin Liška from comment #3)
> I see the same problem (reduced from Chromium package):
Fixed. I suspect that this doesn't address the original issue because it
mentions GCC 8 failing as well. To address that we'll need a testcase that
fails with GCC 8.

Yeah that doesn't look good. I had not done a cpython build; I had started
with a gem5 build (which builds python modules) and only superficially looked
at cpython.
I thought about this over the weekend and agree that silencing the warning will
only hold us back indefinitely. I'll look at the cpython build a bit closer
and try to fix it there when I have time for it. Thanks for looking into this.

So I can really confirm that. There're 2 functions starting on the same line &
column:
gcov-dump -l x.gcno | grep
_ZN24CryptDefaultProviderTest15addTestsToSuiteERN7CppUnit27TestSuiteBuilderContextBaseE
x.gcno: 01000000: 52:FUNCTION ident=851573668, lineno_checksum=0x94de0233,
cfg_checksum=0xb3ccce62,
`_ZN24CryptDefaultProviderTest15addTestsToSuiteERN7CppUnit27TestSuiteBuilderContextBaseE'
/home/dimhen/src/CSPbuild/CSP/unittest/CpCapi20UnitTest/CryptDefaultProviderTest.h:18:5:20
gcov-dump -l x.gcno | grep _ZN24CryptDefaultProviderTest14getTestNamer__Ev
x.gcno: 01000000: 42:FUNCTION ident=1044446335, lineno_checksum=0x6adcbc1d,
cfg_checksum=0x44818b72, `_ZN24CryptDefaultProviderTest14getTestNamer__Ev'
/home/dimhen/src/CSPbuild/CSP/unittest/CpCapi20UnitTest/CryptDefaultProviderTest.h:18:5:18
It would really help me if you could attach pre-processed source file (using -E
option).

New Revision: 257984
URL: https://gcc.gnu.org/viewcvs?rev=257984&root=gcc&view=rev
Log:
[Patch AArch64] Turn on frame pointer / partial fix for PR84521
This fixes a GCC-8 regression that we accidentally switched off frame
pointers in the AArch64 backend when changing the defaults in the common
parts of the code. This breaks an ABI decision that was made in GCC at
the dawn of the port with respect to having a frame pointer at all
times. If we really want to turn this off lets have a discussion around
that separately.
For now turn this back on and I believe this will leave PR84521 latent
again with -fomit-frame-pointer and (hopefully) make the ruby issue go
away. I'm asking Sudi to pick that up.
Bootstrapped and regression tested on AArch64-none-linux-gnu but I see
one regression in gcc.c-torture/execute/960419-2.c which needs to be
looked at next (PR84528, thanks Kyrill).
Ok to put in and then look at PR84528 ?

--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
So fixed? I agree that IPA mucking with functions relying on inlining (all
functions with __builtin_va_arg_pack_* stuff are supposed to be always_inline!)
is pointless.
Of course at the time of IPA those functions should already be inlined
everywhere and we shouldn't end up emitting their bodies un-inlined. In
fact the bodies should have been reclaimed and not entered IPA? Of course
if it is "IPA" SRA then yeah, that should simply ignore all always-inline
functions anyway.

--- Comment #7 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I am not sure it is really fixed. We no longer ICE, howeverw we need
backporting to release branches and also I think we miss fortification whenever
we fail to inline (that is with -Os). I have some patches to inline more of
these fortify wrappers, but still not all of them.

I thought we now force all always-inline inlining to happen during
early inlining? So I wonder how this happened...
For me open is (with -D_FORTIFY_SOURCE=2)
extern __inline __attribute__ ((__always_inline__)) __attribute__
((__gnu_inline__)) __attribute__ ((__artificial__)) int
open (const char *__path, int __oflag, ...)
{
if (__builtin_va_arg_pack_len () > 1)
__open_too_many_args ();
if (__builtin_constant_p (__oflag))
{
if ((((__oflag) & 0100) != 0 || ((__oflag) & (020000000 | 0200000))
== (020000000 | 0200000)) && __builtin_va_arg_pack_len () < 1)
{
__open_missing_mode ();
return __open_2 (__path, __oflag);
}
return __open_alias (__path, __oflag, __builtin_va_arg_pack ());
}
if (__builtin_va_arg_pack_len () < 1)
return __open_2 (__path, __oflag);
return __open_alias (__path, __oflag, __builtin_va_arg_pack ());
}
but of course also declared before that as
extern int open (const char *__file, int __oflag, ...) __attribute__
((__nonnull__ (1)));
so I wonder how the firefox issue manifests itself exactly...

Hi Tom,
Sorry for my general lack of engagement I'm struggling to do much at all to
support the community at the moment.
I have set off a couple of builds to target MIPS16; I don't have any recipe for
bootstrapping with MIPS16 enabled so the most efficient way I can give some
assurance is just the GCC testsuite run cross compiled with a simulator. I've
started two build of GCC without and with the patch and will aim to report back
on the testsuite runs as soon as I can.
Matthew

Sorry, I cannot reproduce this. I've built a cross-compiler from today's trunk
via 'configure --target aarch64-linux-gnu && make all-gcc' (i.e. just to
cc1plus, no binutils etc.) and it doesn't abort.
If possible please add 'g++ -v' output, svn revision, and any other info that
can help me reproduce the issue.

Bug ID: 84569
Summary: g++ -g -O3 consumes all memory
Product: gcc
Version: 6.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jorrit at jorrit dot de
Target Milestone: ---
Created attachment 43503
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43503&action=edit
reduced test case
Compiling the attached reduced test-case with -g -O3 eats more than 14G memory
(at which point I killed the compilation).
Compiling with -g -O2 or with -g -O3 -fno-var-tracking works fine.
This bug behaves similar to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77844
and was triggered the same of our unit tests, except that the reduced test of
77844 does not trigger with g++ 6.3.
Bug triggers with:
- g++ (Ubuntu 5.4.1-2ubuntu1~16.04) 5.4.1 20160904 from Ubuntu 16.04.3

Bug ID: 84570
Summary: [og7, openacc, nvptx] Unused offloaded function
parameters
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Consider the following openacc program:
...
static
void foo(int n, int p[N][N])
{
int i, j, k;
#pragma acc parallel copy(p[0:N][0:N])
for (k = 0; k < n; k++)
{
#pragma acc loop gang
for (i = 0; i < n; i++)
for (j = 0; j < n; j++)
p[i][j] = ...;
}
}
...
The variables that are copied from host to accelerator are: n, i, j, k and *p.
The variables i, j and k are not initialized before the parallel region, nor is
the uninitialized value read in the parallel region, so the copy of these
variables is superfluous.
With the old approach where offloading functions where called with a single
pointer-to-struct argument, we wasted some global memory with this.
With the new "Use functional parameters for data mappings in OpenACC child
functions" approach in the og7 branch, we waste .param space with this.
Depending on the implementation, this may be global memory, but also something
else, which may make the wasting more costly.
Either way, the fact that all the arguments are now individually listed in the
function prototype makes it much easier to spot unused parameters.

--- Comment #9 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
I suppose the same changes ("abort" -> "stop") should also be applied to the
libgomp Fortran test cases?
$ git grep -i abort upstream/trunk --
libgomp/testsuite/libgomp.{,oacc-}fortran/ | wc -l
2016
$ git grep -i fall-intrinsics upstream/trunk --
libgomp/testsuite/libgomp.{,oacc-}fortran/ | wc -l
2
Thus re-opened.

--- Comment #10 from Martin Liška <marxin at gcc dot gnu.org> ---
Thank you very much for help. So I see 2 problems:
a) gcov.c wrong assumes that two functions starting at a same line must end on
the same line -> it's wrong
b) there's broken location map, because for your x.gcno file I see 2 functions
starting as same line & column:
CryptDefaultProviderTest.h:18:5:20 (addTestsToSuite)
and
CryptDefaultProviderTest.h:18:5:18 (getTestNamer__)
and each ending at different line. That should not be possible.
Is the project you are building public so I can build it locally and debug case
b) ?

Alas, its proprietary project :(
Maybe I may try to creduce it?
And, alas, I will need some guidance -- I never creduce --coverage issues, only
ICEs

Ok, give me some time to cook a patch. I would be interested in how the patched
GCC will then handle your project.

Patch candidate
For reduced test-case:
$ cat test.cc
struct A { static int foo () { return 1; }; static int bar () {
int x;
return 2; } };
int main()
{
return A::foo () + A::bar ();
}
I now have:
$ cat test.cc.gcov
-: 0:Source:test.cc
-: 0:Graph:test.gcno
-: 0:Data:test.gcda
-: 0:Runs:1
-: 0:Programs:1
2: 1:struct A { static int foo () { return 1; }; static int bar () {
-: 2: int x;
1: 3: return 2; } };
------------------
_ZN1A3fooEv:
1: 1:struct A { static int foo () { return 1; }; static int bar () {
------------------
_ZN1A3barEv:
1: 1:struct A { static int foo () { return 1; }; static int bar () {
-: 2: int x;
1: 3: return 2; } };
------------------
-: 4:
1: 5:int main()
-: 6:{
1: 7: return A::foo () + A::bar ();
-: 8:}
Which is correct in my opinion. Can you please Dmitry test the patch?

Is that PR debug/84545 or something related?

--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Confirmed. Our comparator breaks here:
/* Prefer SCHED_GROUP_P insns to any others. */
if (SCHED_GROUP_P (tmp_insn) != SCHED_GROUP_P (tmp2_insn))
{
if (VINSN_UNIQUE_P (tmp_vinsn) && VINSN_UNIQUE_P (tmp2_vinsn))
return SCHED_GROUP_P (tmp2_insn) ? 1 : -1;
/* Now uniqueness means SCHED_GROUP_P is set, because schedule groups
cannot be cloned. */
if (VINSN_UNIQUE_P (tmp2_vinsn))
return 1;
return -1;
}
when we have two non-unique insns such that one is in a sched group. That is
not supposed to happen actually, since SCHED_GROUP_P should imply
VINSN_UNIQUE_P. This invariant is broken when sched_macro_fuse_insns sets
SCHED_GROUP_P without looking at deps->readonly.
So while we could get rid of the issue by rewriting the problematic sel-sched
code in terms of SCHED_GROUP_P only, lack of deps->readonly check for
macro-fusion seems like a bigger issue and should be fixed too.

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That said, we accept:
void foo(int i)
{

}
clang++ rejects both: error: constexpr variable cannot have non-literal type
'char const[i]'

Reduced test-case:
$ cat gcov.c
int a, b;
void foo (int value)
{
if (value == 1 || value == 2 || (value >= 33 && value <= 44))
{
a = 1;
if (value == 2)
b = 2;
}
else
a = 4;
}
int main(int argc, char **argv)
{
foo (argc);
}
$ cat gcov.c.gcov
-: 0:Source:gcov.c
-: 0:Graph:gcov.gcno
-: 0:Data:gcov.gcda
-: 0:Runs:1
-: 0:Programs:1
-: 1:int a, b;
-: 2:
1: 3:void foo (int value)
-: 4:{
1*: 5: if (value == 1 || value == 2 || (value >= 33 && value <= 44))
-: 6: {
1: 7: a = 1;
2: 8: if (value == 2)
1: 9: b = 2;
-: 10: }
-: 11: else
#####: 12: a = 4;
1: 13:}
-: 14:
-: 15:
1: 16:int main(int argc, char **argv)
-: 17:{
1: 18: foo (argc);
-: 19:}
As you can see, there's a duplicate expression (value == 2) on lines 5 and 8.
Even with -O0 we do some optimizations and the expression is executed just
once. That's why we report line 8 twice.
Note that we have couple of similar issue caused by similar optimization.

It can explain why we see the strange locations. Note that when you invoke
gcc w/ --coverage, then it creates immediately *.gcno file (notes file) which
contains a timestamp. Then when you run an executable *.gcda file (data file)
is
created. Also included with a timestamp. And the note you see means basically
that
a data file was created before a notes file. Which should not be possible.
Isn't that
an old data file you forgot to remove?

Yes, but it's *.ii file and the x.{gcno,gcda} are related to *.cpp file. Please
attach the resulting gcov file.

Do the:
if (CALL_P (insn))
{
rtx note = find_reg_note (insn, REG_CALL_ARG_LOCATION, NULL_RTX);

remove_note (insn, note);
}

Log:
i386: Update -mfunction-return= for return with pop
When -mfunction-return= is used, simple_return_pop_internal should pop
return address into ECX register, adjust stack by bytes to pop from stack
and jump to the return thunk via ECX register.
Tested on i686 and x86-64.

Yes, although doing it only for the first insn therein is sufficient.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The aarch64_cmpeqdf instruction no longer matches, because the CONST0_RTX
(DFmode) operand doesn't match the aarch64_simd_reg_or_zero predicate.
Either aarch64_simd_reg_or_zero predicate should use
aarch64_simd_or_scalar_imm_zero rather than aarch64_simd_imm_zero, or the
aarch64_cmp<optab><mode> pattern with VHSDF_HSDF needs to use some other
predicate at least for the scalar modes.

--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
What are the "acats tests without -fno-reorder-blocks-and-partition still at
314 failures." failures? Runtime failures, or just failing to assemble or
failing to link? How do non-ada tests with -freorder-blocks-and-partition look
on this target? Perhaps block & partition reordering needs to be disabled,
either on the target for all compilation, or for Ada only, though of course it
would be nice to see why. Is that a regression though? I mean, has
-freorder-blocks-and-partition ever worked on this target for Ada, or just
nobody tested it before?

--- Comment #6 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
If I tweak the testcase like this:
struct seconds { int i_{0}; constexpr seconds (int) {} };
template <char... _Digits> constexpr seconds operator""_s() {
return seconds(0);
}
constexpr seconds operator""_s(long double i) {
return seconds(0);
}
template<class TYPE>
struct Param {
constexpr static inline seconds time_to_wait{10_s};
};
struct Empty {};
Param<Empty> p;
then it's accepted by clang++ and ICEs the same. And if I apply this then it's
accepted by G++, too:

-freorder-blocks-and-partition is just incompatible with SEH at the moment and,
since it's now the default, the end result is obviously a regression. I have
the beginning of a fix but it's still not sufficient.

Log:
Make fix for PR 83965 handle SLP reduction chains
This patch prevents pattern-matching of fold-left SLP reduction chains,
which the previous patch for 83965 didn't handle properly. It only
stops the last statement in the group from being matched, but that's
enough to cause the group to be dissolved later.
A better fix would be to put all the information about the reduction
on the the first statement in the reduction chain, so that every
statement in the group can tell what the group is doing. That doesn't
seem like stage 4 material though.

Bug ID: 84573
Summary: missing warning on an uninstantiated function template
returning T with no return statement
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
G++ diagnoses a return statement with a value in a function template returning
void even when the template is never instantiated, but it doesn't issue a
warning when a function template declared to return the template argument T.
Since the only valid specialization of such a template is one where T = void
it's likely that the missing return statement is a mistake that issuing a
warning for would be helpful.
$ cat z.C && gcc -Wall -Wextra -S z.C
template <class T>
void f () { return 1; } // error: return-statement with a value
template <class T>
T g () { } // missing warning
z.C: In function ‘void f()’:
z.C:2:20: error: return-statement with a value, in function returning ‘void’
[-fpermissive]
void f () { return 1; } // error: return-statement with a value

--- Comment #1 from James Clarke <jrtc27 at jrtc27 dot com> ---
This is a GCC bug. The function "d" here is non-static and thus exported as a
dynamic symbol. On ia64, function descriptors for dynamic symbols are always
allocated by the dynamic linker at runtime for canonicalisation (yes, there are
other things you could do, but this is what was chosen), and therefore are not
link-time constants, even though the contents of this function descriptor can
be determined at link-time (since this is linking an executable). GCC should
instead be placing this in a relro section like you said.

-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:
_Z1fP1C:
.LFB0:
.cfi_startproc

.cfi_def_cfa_offset 16

.LIND1:
call .LIND0

movq %rbx, %rdi
popq %rbx
.cfi_def_cfa_offset 8
movq 16(%rax), %rax
jmp __x86_indirect_thunk_rax
.cfi_endproc
x86-64 is supposed to have asynchronous unwind tables by default, but
there is nothing that reflects the change in the (relative) frame
address after .LIND0. That region really has to be moved outside of
the .cfi_startproc/.cfi_endproc bracket.
This patch adds TARGET_INDIRECT_BRANCH_REGISTER to force indirect
branch via register whenever -mindirect-branch= is used. Now,
-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:
_Z1fP1C:
.LFB0:
.cfi_startproc
pushq %rbx
.cfi_def_cfa_offset 16
.cfi_offset 3, -16
movq (%rdi), %rax
movq %rdi, %rbx
movq 16(%rax), %rax
call __x86_indirect_thunk_rax
movq (%rbx), %rax
movq %rbx, %rdi
popq %rbx
.cfi_def_cfa_offset 8
movq 16(%rax), %rax
jmp __x86_indirect_thunk_rax

Confirmed. The warning suppression code sees the following statements:
<bb 2> :
_8 = &b_3(D)->_a;
_9 = _8;
...
_6 = &MEM[(struct String *)_1]._string;
__builtin_strncpy (_6, "123", len_7);
MEM[(struct String *)_1]._string[len_7] = 0;
but it doesn't have the smarts to figure out that _6 is &MEM[(struct String
*)_1]._string.

gcc/testsuite/gcc.target/powerpc/sse2-pmuludq-1.c
Test requres Power 8 as a minimum. Compiling with -mcpu=power7 generates an
ICE but the test requires Power8. So the ICE shouldn't be an issue under
normal testing conditions.

Summary: Function return thunks shouldn't be aliased to
indirect branch thunks
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Target: x86-64
Function return thunks shouldn't be aliased to indirect branch thunks
since indirect branch thunks are placed in COMDAT section and a COMDAT
section with indirect branch may not have return thunk:

void
foo (void)
{
}
[hjl@gnu-skx-1 xxx]$ cat y.i
extern void foo (void);
int
main ()
{
foo ();
return 0;
}

Coming out of SSA for hand_benchmark_cache_ronly(), we seem to be calculating:
((index + 1) * 8) + x
((index + 2) * 8) + x
((index + 3) * 8) + x
etc
After slsr we have:
(index * 8) + x
(((index * 8) + 8) + x)
((((index * 8) + 8) + 8) + x)
And finally after forwprop4:
(index * 8) + x
(((index * 8) + 8) + x)
(((index * 8) + 16) + x)
Are you suggesting we reassociate the above as:
((index * 8) + CONSTANT) + x
Is there a preferred place to put this kind of transformation? A separate pass
after forwprop4? Much earlier? Is there a pass that already does this kind of
juggling?
BTW, it seems like a pass like tree-ssa-reassoc, tries to precisely convert:
x + (y + constant) INTO (x + CONSTANT) + y
which is the opposite of what we want.

Summary: g++: internal compiler error: Segmentation fault
(program cc1plus)
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vegard.nossum at gmail dot com
Target Milestone: ---
The following is obviously not a valid C++ program but crashes the compiler:
a(){[](class{
Output:
<source>:1:3: error: ISO C++ forbids declaration of 'a' with no type
[-fpermissive]
a(){[](class{
^
<source>: In function 'int a()':
<source>:1:13: error: types may not be defined in parameter types
a(){[](class{
^
<source>:1:13: error: expected '}' at end of input
<source>:1:13: error: expected ',' or '...' at end of input
<source>:1:13: error: expected ')' at end of input
g++: internal compiler error: Segmentation fault (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
Compiler returned: 4
I used C-Reduce on a bigger program to find a smaller test case.

--- Comment #2 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
Paolo, you're right. Sorry for the noise.
The "-fconcept" parameter is a left-over from the larger testcase where this
snippet was derived from.
The ICE can be reproduced with GCC 4.9.0 and only needs "-std=c++14" or
"-std=c++1y" to be triggered.

Bug ID: 84577
Summary: snprintf with null buffer not eliminated when return
value is in a known range
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
The sprintf pass eliminates snprintf calls with a null buffer and zero size
when whose return value is a constant but it does not eliminate calls whose
return value is in some range. Both calls can be eliminated.
$ cat b.c && gcc -O2 -S -Wall -Wextra -fdump-tree-optimized=/dev/stdout b.c
void f (void)
{
int n = __builtin_snprintf (0, 0, "%hhx", 123); // eliminated
if (n < 0 || 2 < n)
__builtin_abort ();
}
void g (int i)
{
int n = __builtin_snprintf (0, 0, "%hhx", i); // not eliminated but could
be
if (n < 0 || 2 < n)
__builtin_abort ();

--- Comment #2 from Jim Wilson <wilson at gcc dot gnu.org> ---
rdynamic is a linker option that the compiler ignores, except to pass on to the
linker. As far as the compiler knows, you are building a non-pic application,
and hence the symbol is local. We can't assume that -rdynamic will be used at
compile time, and hence to make this work we must assume that any local symbol
might become global at link time.
We can fix this my modifying the ia64_reloc_rw_mask function to return 3 when
non-pic, same as it does when pic, to indicate that local symbols with relocs
aren't read-only.
I don't have access to ia64 hardware, so I don't have any easy way to test
this.
The symbol ends up in .data.rel.ro.local instead of .data.rel.ro, but
presumably that is OK.

Ah I see, that explains it.

That's what happens on hppa which has similar function descriptor behaviour, so
that should be fine.

Hi,
When you want to build a project where for some reason you want to use fat LTO
objects, but don't want to actually use it a link time (ie when you want to
experiment with LTO but still allow to easily disable it), you might end up
doing this:
gcc -flto -ffat-lto-objects -fPIC -o file.o -c file.c
gcc -fno-lto -fPIC -shared -o file.so file.o
with gcc 8 though, this leaves the symbol __gnu_lto_v1 which is unexpected to
remains in the final shared library:
gcc-nm -g file.so
0000000000201020 B __bss_start
w __cxa_finalize@@GLIBC_2.2.5
0000000000201020 D _edata
0000000000201028 B _end
0000000000000609 T f
000000000000060c T _fini
w __gmon_start__
0000000000201021 B __gnu_lto_v1
0000000000000508 T _init
w _ITM_deregisterTMCloneTable
w _ITM_registerTMCloneTable
Would it be possible to trim out __gnu_lto_v1 when we have fat inbound objects,
but lto is explicitly deleted with -fno-lto ?
Cheers,
Romain

--- Comment #2 from Ruslan Nikolaev <nruslan_devel at yahoo dot com> ---
Summary (from the mailing list):
Pros of the proposed approach:
1. Ability to use guaranteed lock-free double-width atomics (when mcx16 is
specified for x86-64, and always for arm64) in more or less portable manner
across different supported architectures (without resorting to non-standard
extensions or writing separate assembly code for each architecture). Hopefully,
the behavior may also be made more or less consistent across different
compilers over time. It is already the case for clang/llvm. As mentioned,
double-width lock-free atomics have real practical use (ABA tags for pointers).
2. More likely to find a bug immediately if a programmer tries to do something
that is not guaranteed by the standard (i.e., getting segfault on read-only
memory when using double-width atomic_load). This is true even if mcx16 is not
used, as most CPUs have cmpxchg16b, and libatomic will use it.On the other
hand, atomic_load implemented through locks may have hard-to-find and debug
issues in signal handlers, interrupt contexts, etc when a programmer
erroneously assumes that atomic_load is non-blocking
3. For arm64 the corresponding instructions are always available, no need for
mcx16 flag or redirection to libatomic at all (libatomic may still keep old
implementation for backward compatibility).
4. Faster & easy to analyze code when mcx16 is specified.
5. Ability to tell for sure if the implementation is lock-free by checking
corresponding C11 flag when mcx16 is specified. When unspecified, the flag will
be false to accommodate the worst case scenario.
6. Consistent behavior everywhere on all platforms regardless of IFFUNC, mcx16
flag, etc. If cmpxchg16b is available, it is always used (platforms that do not
support IFFUNC will use function pointers for redirection). The only thing the
mcx16 flag changes is removing indirection to libatomic and giving guaranteed
lock_free flag for corresponding types. (BTW, in practice, if you use the flag,
you should know what you are doing already)
7. Ability to finally deprecate old __sync builtins, and use new and more
advanced __atomic everywhere.
Cons of the proposed approach:
1. Compiler may place const atomic objects to .rodata. (Avoided by making sure
_Atomic objects with the size > 8 are not placed in .rodata + clarifying that
casting random .rodata objects for double-width atomics is undefined and is not
allowed.)
2. Backward compatibility concerns if used outside glibc/IFFUNC. Most likely,
even in this case, not an issue since all calls there are already redirected to
libatomic anyway, and statically-linked binaries will not interact with new
binaries directly.
3. Read-only memory for atomic_load will not be supported for double-width
types. But it is actually better than hiding the problem under the carpet
(current behavior is actually even worse because it is inconsistent across
different platforms, i.e. different for x86-64 in Linux and arm64). Anyway, it
is better to use a lock-based approach explicitly if for whatever reason it is
more preferable (read-only memory, performance (?), etc).

Bug ID: 84580
Summary: Equality and relational ops for containers behave
differently in Debug Mode
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
This passes in normal mode but fails the second assertion when compiled with
-D_GLIBCXX_DEBUG
#include <cassert>
#include <vector>
struct foo { };
typedef std::vector<foo*> vect;
bool operator==(const vect&, const vect&) { return true; }
int main() {
vect v1;
vect v2;
v1.push_back(nullptr);
assert(v1 == v2);
assert(!(v1 != v2));
}
The problem is that in Debug Mode (v1 != v2) doesn't call (v1 == v2) which
would use the custom ::operator== overload.
Instead it calls (v1.base() != v2.base()) which then calls operator==, but with
arguments of type std::__cxx1998::vector, and so won't use the ::operator==
overload.
I think we need to make std::__debug::operator!= use == so that ADL can find
the same overload as would be found in normal mode, and similarly for >, <= and
>= (from Table 77, Optional container operations).

Summary: GCC expects "override" keyword in incorrect grammar
position
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: myriachan at gmail dot com
Target Milestone: ---
GCC expects the "override" keyword in an incorrect position in the C++ grammar:
#define MEOW 256
struct Base {
virtual const char (&GetBuffer() const)[MEOW] = 0;
};
struct Derived : public Base {
// GCC requires this incorrect syntax...
virtual const char (&GetBuffer() const override)[MEOW];
// ...but the below is the correct syntax, which GCC rejects.
virtual const char (&GetBuffer() const)[MEOW] override;
};
In the C++ Standard, "override" is a virt-specifier in a virt-specifier-seq.
virt-specifier-seq optionally goes after the declarator. After the optional
virt-specifier-seq goes the optional pure-specifier.
Possibly related bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64794 (I
don't know whether "-> override" is sensible; just linking this in case that
bug's reporter is correct.)

Reduced:
struct Base {
virtual const char (&GetBuffer() const)[1] = 0;
};
struct Wrong : Base {
// GCC requires this incorrect syntax...
virtual const char (&GetBuffer() const override)[1];
};
struct Correct : Base {
// ...but the below is the correct syntax, which GCC rejects.
virtual const char (&GetBuffer() const)[1] override;
};
This gives:
o.cc:11:46: error: expected ‘;’ at end of member declaration
virtual const char (&GetBuffer() const)[1] override;
^
;
o.cc:11:48: error: ‘override’ does not name a type
virtual const char (&GetBuffer() const)[1] override;
^~~~~~~~
EDG behaves the same as G++ but Clang gets it right.

It's isolated from Firefox, hope it's a valid code:

static const long b = 0;
static const unsigned c = (b);
};
$ g++ RegExp.ii
RegExp.ii:3:31: error: non-constant in-class initialization invalid for static
member ‘a< <template-parameter-1-1> >::c’
static const unsigned c = (b);
^
RegExp.ii:3:31: note: (an out of class initialization is required)

Bug ID: 84583
Summary: -fdirectives-only does not handle CRLF properly
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: boris at kolpackov dot net
Target Milestone: ---
Created attachment 43515
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43515&action=edit
reproducing source code
The attached archive contains foo.c (as well as foo.p and foo.i, for reference)
that if preprocessed with -fdirectives-only on Windows (for example, using the
MinGW build of GCC) produces incorrect result:
gcc.exe -E -fdirectives-only -o foo.p foo.c
gcc.exe -E -fpreprocessed -fdirectives-only -x c foo.p >foo.i
foo.c:7:16: warning: missing terminating " character
foo.c:9:30: warning: missing terminating " character
It appears that in the first invocation GCC replaces each LF character with the
CRLF sequence thus ending up with CRCRLF sequences.
Will be happy to test a patch.

After rebuild all and re-run myproject' tests I can confirm
1) r257859 FAIL
2) r257859 + patch from c#14 PASS
3) there are NO "stamp mismatch with notes file" from c#17
Thank you, Martin!

Broken again!-(
And I cannot find anything relevant in

AFAICT the situation has not changed in F2018.
What should we do with this PR?

--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This change would meet the standard's requirement that a != b is equivalent to
!(a == b)
--- a/libstdc++-v3/include/debug/vector
+++ b/libstdc++-v3/include/debug/vector
@@ -725,7 +725,7 @@ namespace __debug
inline bool
operator!=(const vector<_Tp, _Alloc>& __lhs,
const vector<_Tp, _Alloc>& __rhs)
- { return __lhs._M_base() != __rhs._M_base(); }
+ { return !(__lhs == __rhs); }
template<typename _Tp, typename _Alloc>
inline bool
It would change the behaviour for this program:
#include <debug/vector>
#include <cassert>
struct foo { };
bool operator!=(std::vector<foo*> const& v1, std::vector<foo*> const& v2)
{ return &v1 != &v2; }
int main()
{
__gnu_debug::vector<foo*> v1, v2;
assert(v1 != v2);
}
Currently the operator!= for debug vectors calls the program-defined overload
for std::vectors, but with the patch above it would call operator== for debug
vectors which calls the standard operator== for std::vectors. This is probably
OK, the program above is pathologically contrived, and meeting the standard
requirements when _GLIBCXX_DEBUG is defined is more important, so that
_GLIBCXX_DEBUG doesn't change semantics.

You are right. I also cannot reproduce the original issue anymore w/ r257975.

--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
So the issue is
for (i = 0; i < N; i++)
{
y[i] = i;
for (j = 0; j < N; j++)
{
if (j > 500)
{
x[i][j] = i + j + 3;
y[j] = i*j + 10;
^^^
here we now verify that we can instantiate i*j + 10 at this point which
is (int) {10, +, {0, +, 1}_3}_4 and that fails the graphite_can_represent_scev
test because of
case POLYNOMIAL_CHREC:
/* Check for constant strides. With a non constant stride of
'n' we would have a value of 'iv * n'. Also check that the
initial value can represented: for example 'n * m' cannot be
represented. */
gcc_assert (loop_in_sese_p (get_loop (cfun,
CHREC_VARIABLE (scev)), scop));
if (!evolution_function_right_is_integer_cst (scev)
|| !graphite_can_represent_init (scev))
return false;
given CHREC_RIGHT is {0, +, 1}_3 and not an INTEGER_CST.
I think with graphite_can_represent_scev I used the wrong tool (it is supposed
to guard what extract_affine handles). Testing a patch.

I guess we haven't spelled that out in the docs, but the thought is that one
would use the __atomic builtins like one would use C11/C++11 atomics. In that
world, only "address-free" atomic types are guaranteed to work when mapped from
another process, for example, and only lock-free types are address-free. (That
doesn't quite cover all cases, such as when making process-private read-only,
but it gives at least some idea of what's the intent.)
Users should ensure that the particular type is lock-free (or that atomic ops
on that type are) to know that it's safe to use atomic loads on read-only
memory. The most recent GCC shouldn't declare the types to be lock-free just
because cmpxchg16b is available.
It might still use it under the covers, but the fact that it's not lock-free
indicates that the implementation is not just native atomic operations as
supported by the hardware, but something different.
I guess we need to spell this out in the docs.

We have

and cxx_constant_value -> maybe_constant_init_1 doesn't evaluate it now:
5154 if (!is_nondependent_static_init_expression (t))

and that CONVERT_EXPR isn't is_nondependent_static_init_expression.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Given:
class C {
static const long b = 0;
static const unsigned c = (b);
};
class D {
static const long b = 0;
static const unsigned c = b;
};
template <class> class A {
static const long b = 0;
static const unsigned c = (b);
};
template <class> class B {
static const long b = 0;
static const unsigned c = b;
};
we only reject the A case.
For D and B there is just INTEGER_CST, and for C and A we have:
(unsigned int) (long int) *(const long int &) &b
because of the parens.
The reason why it is accepted outside of template and not inside of it is that
cxx_constant_init calls is_nondependent_static_init_expression which calls
instantiation_dependent_expression_p and that is true in A::c.

4857 calls to backtrace()
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
I think the issue lies within libgfortran show_backtrace which does
lbstate = backtrace_create_state (NULL, __gthread_active_p (),
error_callback, NULL);
for each call to backtrace (). There doesn't seem to be a corresponding
backtrace_free_state API so we leak whatever is allocated here. Ian?
I suppose a workaround would be to make lbstate static and only initialize
it if NULL.

note the above is wrong when the __gthread_active_p () state changes.
Ian, I suppose there should be an API to deallocate the state?

gcc tells you when warning which switch you can use to disable the diagnostics.
There's a whole family of -Wformat-* options.

--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note that volatiles are not optimized and thus by having
typedef struct {
volatile unsigned int slock;
} arch_spinlock_t;
you might pessimize things. The code looks heavily dependent on inline asms
and
inlining so it's a bit hard to analyze as well.

Hmm, is p->a valid to compute if p is NULL? Is it valid to compute p->b if p
is NULL for
struct A { char a[4]; char b[4]; };
?
Because you say "could" in
if (p->a == 0) // could only be true when p is null
__builtin_abort (); // can be eliminated
which implies it would invoke undefined behavior?
ISTR we still want to not break old offsetof implementations using &(T
*)0->member
style computation?
But yes, wrapping rules say that &p->m is never NULL if m is not a member
at offset zero. See tree_single_nonzero_warnv_p for ADDR_EXPR handling.

warning: unknown conversion type character 'P' in format [-Wformat=]

This [-Wformat=] doesn't give me any clue.
What does this mean?
> There's a whole family of -Wformat-* options.
But I can't find -Wno-format-unknown-specifier,
am I missing something?

Started to ICE in between r152207 and r152360, seems endless recursion in

BTW, when using creduce, if the original is valid or has just one error or
something similar, please try to write the script such that it will not confirm
a reduction which has also other errors, otherwise you end up with testcases
like this which have just too many errors in it.

Would be interesting to see differences in -fopt-info-vec between those two

But that rev. should have a fix that made us consider using runtime alias check
at all? That part could be backported and this loop not vectorized.

Summary: Incorrect acess checking with inheritance

Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dllmain at yandex dot ru
Target Milestone: ---
Created attachment 43516
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43516&action=edit
preprocessed source(in version which cause error)
Consider the code:
#include <tuple>
#ifdef USING_SIMPLE_BASE
#define BASE base<T>
#else
#ifdef USING_DIFFERENT_NAME
#define NAME type_
#else
#define NAME type
#endif
#define BASE tuple_element_t<0,std::tuple<base<T>>>
#endif
//Simple trait for replacement of nested name
template<std::size_t I, typename T> struct tuple_element
:private std::tuple_element<I,T>::type
{
using NAME = typename std::tuple_element<I,T>::type;
};
template<std::size_t I, typename T>
using tuple_element_t = typename tuple_element<I,T>::NAME;
template<typename> struct base { protected: using type = int; };
template<typename T> struct derived :private BASE { using BASE::type; };
int main() { return derived<int>::type(0); }
It fails to compile until 'USING_SIMPLE_BASE' or 'USING_DIFFERENT_NAME' macros
would be defined:
$ g++ -xc++ -std=c++14 -pedantic-errors -DUSING_SIMPLE_BASE -o/dev/null
test.cxx
$ #build success
$ g++ -xc++ -std=c++14 -pedantic-errors -DUSING_DIFFERENT_NAME -o/dev/null
test.cxx
$ #build success
$ g++ -xc++ -std=c++14 -pedantic-errors -o/dev/null test.cxx
test.cxx: In function 'int main()':
test.cxx:27:35: error: 'using type = int' is protected within this context
int main() { return derived<int>::type(0); }
^~~~
test.cxx:23:61: note: declared protected here
template<typename> struct base { protected: using type = int; };
^
In all cases 'derived' inherits 'base', so 'base::type' is available in context
of 'derived' class. Using declaration in public section of 'derived' do
'derived<>::type' available in global context. However, g++ not accepts all
variants of code.
$ g++ -v

Thanks, I will try to do this in the future. I believe the original had only
one error.

--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. We're just hoisting the __builtin_assume_aligned call here but when
inserting it we do not apply its effect to the LHS. That's originally done
by the CCP pass only btw. but there's no further CCP instance after PRE.
Note PRE cannot easily transfer possibly conditional information along with
the expressions it moves.
The easiest fix^Whack would be to special-case BUILTIN_ASSUME_ALIGNED when
inserting the hoisted call in create_expression_by_pieces...

unaligned loads from non-aggregates should be fully supported these days even
on strict-align targets where they will result in bitfield extracts.

--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. This is another case where we vectorize one loop but not the other
and DOM doesn't handle removing vector loads against scalar stores. Later
store-merging aggregates the stores but nothig performs CSE after it.
The vectorizer decides that vectorizing the reduction is profitable while
vectorizing the init is not:
t.c:4:3: note: Cost model analysis:
Vector inside of loop cost: 68
Vector prologue cost: 8
Vector epilogue cost: 128
Scalar iteration cost: 16
Scalar outside cost: 0
Vector outside cost: 136
prologue iterations: 0
epilogue iterations: 2
t.c:4:3: note: cost model: the vector iteration cost = 68 divided by the scalar
iteration cost = 16 is greater or equal to the vectorization factor = 4.
t.c:4:3: note: not vectorized: vectorization not profitable.
With -fno-vect-cost-model we vectorize both loops and optimize the function
like clang does.
The issue with the cost model here is that for the scalar iteration cost
we end up using builtin_vectorization_cost () while for the vector cost
we use add_stmt_cost. Only the latter makes a difference between the
different kind of operations.
I have a patch.

--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
...with that we get the original ICE in PR84325 back:
internal compiler error: unexpected expression ‘(const
seconds){operator""_s<'1', '0'>()}’ of kind implicit_conv_expr
constexpr static inline seconds time_to_wait{10_s};
so that's another bug that needs to be fixed while at this.

Version:
xgcc (GCC) 8.0.1 20180204 (experimental)
built from git fdae6180ad24fa6303fa046114f3e4b66b8db34d
Version 7.3.0 doesn't seem to be affected AFAICS.
Test case was reduced using C-Reduce (preserving the number of errors in the
original input).
I've also submitted bug #84576 and bug #84585 which could be related.
You can also tweak the input slightly to get a different crash:
struct a {
void b() {}
void c(x = [] {
if (a a(int auto){})
;
}) {}
};

--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note we don't do loop merging here but final value replacement does it's job.
What is missing is jump-threading the two loop header copy checks count/2 != 0
and
i < count if that is easily possible. So we end up with
if (count/2 != 0)
g += count/2;
# tem = PHI <count/2, 0>
if (count > tem)
g += count - tem;
those loop header checks also stand in the way of loop fusion (well, it's not
classical fusion given the different iteration spaces).
Not sure why DOM doesn't consider threading the above. Eventually it's
a very special phiopt opportunity as well (but late phiopt runs too late).
<bb 2> [local count: 118111601]:
_20 = count_11(D) >> 1;
if (_20 != 0)
goto <bb 3>; [89.00%]
else
goto <bb 4>; [11.00%]
<bb 3> [local count: 105119325]:
<bb 4> [local count: 118111600]:
# i_22 = PHI <_20(3), 0(2)>
if (count_11(D) > i_22)
note phiopt already does
PHI i_22 reduced for COND_EXPR in block 2 to _20.
so we end up with
<bb 4> [local count: 118111600]:
# i_22 = PHI <_20(3), _20(2)>
if (count_11(D) > i_22)
goto <bb 5>; [89.00%]
but nothing simplifies it further on GIMPLE. Note that of course
count_11(D) > count_11(D) >> 1 isn't always true.

--- Comment #3 from Ian Lance Taylor <ian at airs dot com> ---
Yes, the intended use is certainly to create the state once per program. Each
time you create a new state and use it for a backtrace the code does a bunch of
initialization work reading the debug info. Much better to do that only once.
Plus there is the memory leak problem.
That said, yes, there should be a function to free a state. But this code
should really change to create the state once anyhow, if at all possible.

Bug ID: 84589
Summary: Failure to diagnose conflicting declaration of struct
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: accepts-invalid
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
void stat(struct stat*) { }
namespace ns
{
using ::stat;
struct stat { };
}
This should be ill-formed, because the function declaration also adds "struct
stat" to the global namespace, so the using-declaration adds that to ns, and
defining struct ns::stat should conflict.
Clang says:
using.cc:6:3: error: declaration conflicts with target of using declaration
already in scope
struct stat { };
^
using.cc:1:18: note: target of using declaration
void stat(struct stat*) { }
^
using.cc:5:11: note: using declaration
using ::stat;
^
1 error generated.
and EDG says:
"using.cc", line 6: error: class "stat" cannot be defined in the current scope
struct stat { };
^
1 error detected in the compilation of "using.cc".

The patch at https://gcc.gnu.org/ml/fortran/2018-02/msg00181.html fixes several
tests in this PR, but not the ones in comment 14
f951: internal compiler error: Segmentation fault: 11
and comment 15
end
internal compiler error: in output_constructor_regular_field, at varasm.c:5031
In addition, I don't understand why
type t
character :: z
end type t
type(t), parameter :: s(5) = t('a')
type b
character :: y(5) = transfer('abcde', s(1)%z)
end type
type(b) :: zz
print *, zz
print *, s(1)%z
end
prints
aaaaa
a
Should not it be
abcde
a
?

Probably related to us doing SCEV analysis w/o updating SSA form but
follow_copies_to_constant and degenerate_phi_result not honoring that.
The following would fix this:

--- Comment #2 from Jason Merrill <jason at gcc dot gnu.org> ---
The testcase has undefined behavior; the initializer_list array only lives
until the end of the initialization of 'a'.
11.6.4p6: The array has the same lifetime as any other temporary object (15.2),
except that initializing an initializer_list object from the array extends the
lifetime of the array exactly like binding a reference to a temporary.
15.2p6.9: A temporary object bound to a reference parameter in a function call
(8.5.1.2) persists until the completion of the full-expression containing the
call.
The code can be fixed by explicitly extending the initializer_list lifetime,
e.g.
std::initializer_list<const char> il = {'a', 'b', 'c'};
ArrayView<const char> a (il);

Thank you Jason for nice clarification ;)

Note I think all cases are on the border of being invalid. In C++ the ODR
forbids interposition with "different" objects.
You simply have to ensure to provide compatible definitions when interposing
others.

Warning-free testcase:

template <typename T>
struct bar : public base {

Confirmed. This isn't easy to do given only the linker can. When using GNU ld
one might be able to use filter objects or some custom linker scripts but don't
hold your breath.
I'd rather like to see those common symbols to die completely - though that's
equally hard given they have been hardcoded into binutils meanwhile... Using
ELF notes or simply keying on section names should be possible as well. It's
only the non-linker-plugin path which uses nm to look for objects with LTO
bytecode that might be harder to fix (well, use readelf or similar tools or
simply use a simple-object handler).

Bug ID: 84592
Summary: [openacc] lto1: ICE in input_varpool_node, at
lto-cgraph.c:1424: for CSWTCH symbol
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Consider the following openacc testcase:
...
/* { dg-additional-options "-ftree-switch-conversion" } */
#include <stdio.h>
#pragma acc routine seq
static int __attribute__((noinline)) foo (int n)
{
switch (n & 3)
{
case 0: return 4;
case 1: return 3;
case 2: return 2;
default:
return 1;
}
}
int
main (void)
{
int n[1];
n[1] = 4;
#pragma acc parallel copy(n)
{
n[0] = foo (n[0]);
}
printf ("n: %d\n", n[0]);
return 0;
}
...
When compiling this (by copying it into
libgomp/testsuite/libgomp.oacc-c-c++-common), we run into:
...
lto1: internal compiler error: in input_varpool_node, at lto-cgraph.c:1424^M
0x959ebb input_varpool_node^M
gcc/lto-cgraph.c:1422^M
0x959ebb input_cgraph_1^M
gcc/lto-cgraph.c:1544^M
0x959ebb input_symtab()^M
gcc/lto-cgraph.c:1858^M
0x5aceac read_cgraph_and_symbols^M
gcc/lto/lto.c:2891^M
0x5aceac lto_main()^M
gcc/lto/lto.c:3356^M
...
When running lto1 using gdb we find the node we're processing is:
...
(gdb) call debug_generic_expr ( node.decl )
CSWTCH.4
...
The CSWTCH.4 is a symbol introduced by -ftree-switch-conversion. If we use
-fno-tree-switch-conversion there's no ICE.

--- Comment #2 from Jan Nordholz <jnordholz at sect dot tu-berlin.de> ---
Hi,
sorry for reopening, but I don't think the comment properly addresses the bug
report.
a) This is not about C++ - the example is pure C, and weak definitions are an
established mechanism.
b) I don't see how the overriding of a weak 'const int y' with a strong 'const
int y' might count as an "incompatible definition". The implicit-sized arrays
might be a different story, true, but I can't see how you've refuted my first
example.
I understand that this is probably a minor issue, as weak objects are probably
only used by a minority of developers. Still, gcc silently generates buggy code
which could only be prevented by either
1. moving the weak definition into a different compilation unit than (all) the
code that uses it or
2. by compiling at less than -O2.
If you consider this too low-prio, I'd gladly try to whip up a patch myself if
I find the time.

--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
It's not just -faggressive-loop-optimizations, it seems that constructors of
weak globals are available for folding, and I really doubt that's actually
intended; after all, GCC does always consider weak function interposable, so
why not objects? Compare:
__attribute__((weak)) const int x=0; int f(){return x==0;}
f:
movl $1, %eax
ret
vs.
__attribute__((weak)) int x(void){return 0;} int f(){return x()==0;}
f:
subq $8, %rsp
call x
testl %eax, %eax
sete %al
movzbl %al, %eax
popq %rdx
ret

Bug ID: 84595
Summary: __builtin_trap() causes optimizer to remove code
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: danielgutson at gmail dot com
Target Milestone: ---
__builtin_trap() cannot be used as a breakpointing mechanism because the
optimizer removes all subsequent code:
#include <stdio.h>
int main()
{
__builtin_trap();
printf("hello world\n");
return 0;
}
Then
main:
ud2
I propose, as a feature, either to provide a new command line option to control
whether the code is optimized out or preserved, or to a add a new builtin
function.

No.

print *. s(1)%z, rank(s(1)%z) gives

I'm looking into the same kind of ICE
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84582#c4) but this one is
invalid.

Fixed for 7.4 as well. The fix depends on earlier patches that aren't on the 6
branch, so I'm inclined to leave it unfixed there.

When p is null p->a is not valid if it's evaluated. offsetof (along with
sizeof and alignof and the like) don't evaluate their operands so they are
exempt.

I'll have a look at the ICE.
I do question ever counting the number of xxlor's in our code, since the
backend will generate them for doing register copies, which can fluctuate given
changes in the RTL, phases of the moon, etc.

but rather with r114364 which revamped the ms bitfield layout completely.
See https://gcc.gnu.org/ml/gcc-patches/2006-04/msg01064.html for more info.
The above testcase indeed passes with -D_WIN32 -mms-bitfields when built with
GCC 4.1 or earlier.
Ignoring the type_align bump in place_field for DECL_PACKED fields sounds
reasonable, just the formatting is wrong (needs a space in between DECL_PACKED
and (field)).
In the second hunk, the formatting is also wrong (e.g. a single statement body
of else shouldn't be wrapped with {}s around it), but more importantly it is
unclear why that would be the right thing, e.g. why is ignoring
maximum_field_alignment the right thing etc.
So, for the first two hunks in #c26 I'd go with:

instead.
The #c26 third hunk is I presume instead something that was probably broken
only in GCC 4.6 with r184409 aka PR52238 fix. That
if (targetm.ms_bitfield_layout_p (rli->t))
rli->prev_field = NULL;
in that patch looks wrong to me, you lose all the special handling of
rli->prev_field that way.
Before trying to deal with that, I think it is important to figure out what VC
does for the case when a bitfield is followed by another bitfield with the same
underlying type size, but higher alignment.
E.g. how is:
struct S {
int a : 2;
__declspec(align(8)) int b : 2;
int c : 28;
__declspec(align(16)) int d : 2;
int e : 30;
} s;
int a = sizeof (struct S);
void f1 (int x) { s.a = x; }
void f2 (int x) { s.b = x; }
void f3 (int x) { s.c = x; }
void f4 (int x) { s.d = x; }
void f5 (int x) { s.e = x; }
compiled by VC? Godbolt.org seems to be down right now, checking some clang
version with -fms-extensions -mms-bitfields shows that the differences in type
alignments don't break the bitfield packs, a, b, c are all packed into a single
32-bit word at offset 0, then d and e are packed into another 32-bit word at
offset 16 (so the alignment is honored for the first bitfield in the pack).
If that is what VC does, then one way to deal with this would be to replace:
if (known_align < desired_align)
with
if (known_align < desired_align
&& (!targetm.ms_bitfield_layout_p (rli->t)
|| rli->prev_field == NULL))
drop the
if (targetm.ms_bitfield_layout_p (rli->t))
rli->prev_field = NULL;
and deal with the further alignment (basically duplicate the if (known_align <

Alternative fix
Here's an alternative fix that I'll run through multi-target testing.
It's more conservative than the cselib.c patch linked above.

Oops, that's the wrong place to check -- will do it in init_alias_analysis
instead.

What you want is __builtin_breakpoint (if that existed). Trap is considered as
noreturn just like abort/exit.

Thanks for filing this (and the other bugs!).
Please open separate bug reports when the crash/input look different: if they
are duplicates we can mark them as such, but if they aren't, having them under
the same bug number makes it harder to talk about them.
Confirmed.
The "-O3" isn't necessary to trigger the crash.
The first testcase crashes here:
#1 0x00000000009e7ec5 in cp_parser_ctor_initializer_opt_and_function_body
(parser=0x7ffff7ffbbd0, in_function_try_block=false)
at ../../src/gcc/cp/parser.c:21770
21770 DECL_CONSTRUCTOR_P (current_function_decl)
due to "current_function_decl" being NULL.
The crash in cp_parser_ctor_initializer_opt_and_function_body started in
r251433 (with -std=c++14), but I'm able to reproduce a crash with the first
testcase within start_lambda_scope with -std=c++11, which started with r204714.
The second testcase is a different crash; it's a failure of this assertion:
970 gcc_checking_assert (length () > 0);
(gdb) bt
#0 fancy_abort (file=0x20fcd7c "../../src/gcc/vec.h", line=970,

OK. That was my second suggested alternative.
BTW I didn't see __builtin_trap documented as noreturn in the documentation.

Depends on the reading of __builtin_trap documentation.
My reading says it does not return.
"This function causes the program to exit abnormally. GCC implements this
function by using a target-dependent mechanism (such as intentionally executing
an illegal instruction) or by calling abort."
Since the documentation talks about calling abort, I would assume __built_trap
should be treated almost the same as calling abort.

OK. I'll leave this issue as a feature request for __builtin_break(). Maybe the
component should be changed to something more appropriate?

--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Both testcases used to ICE with -std=c++11, but that was fixed sometime between
r218865 (ICE) and r218948 (no ICE).
Both testcases ICE on trunk with -std=c++14, in both cases starting with
r208426.

fixes this testcase, but breaks bf-ms-layout.c and bf-ms-layout-2.c.
The tests were adjusted in r186880 and r184519, but perhaps those were just
bogus changes. I guess what matters more is whether the layout in those tests
and in the above tests match what VC does.

--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
I think the code should be rejected in constexpr contexts, as Clang does.
Otherwise the size of A::x is zero, which would make it an invalid object. I'm
changing it to ice-on-invalid-code but please let me know if you know of an
argument for accepting it.

Right, because &b is value-dependent. I guess force_paren_expr can't do that
transformation in a template.

So do you think that we don't want the patch in Comment 3?

--- Comment #2 from seurer at gcc dot gnu.org ---
xxlor counting failures are really common for powerpc test cases. Perhaps we
should look at all the ones that do that to see if those xxlor count checks are
actually testing for anything useful?

Bug ID: 84600
Summary: function inlining is confused by char * type cast
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: popinet at basilisk dot fr
Target Milestone: ---
Created attachment 43521
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43521&action=edit
test.c
The attached code fails when run using:
gcc -Wall -Wextra -O2 test.c -o test && ./test
using -O1 or -fno-strict-aliasing or not using inlining fixes the problem.
Switching to gcc versions < 6 or to clang 3.8.1 also fixes the problem, as do
the various modifications suggested as comments in the code.
The fact that uncommenting the (always true) condition fixes the problem is
particularly curious.
Thank you for your attention.

--- Comment #3 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
Actually, it is not a failure. I believe it is an improvement. We have less
move insns now. The easiest way to fix is to change the expected move insns to
the current number.
I'd prefer changing the exact counts to less or equal number of the counts.
But I don't know how to write it using dejagnu test directives.

Without optimization, -fsanitize=undefined shows:
/tmp/t.c:13:22: runtime error: signed integer overflow: 968551222 * 3 cannot be
represented in type 'int'
With -O2, -fsanitize=undefined shows:
/tmp/t.c:13:22: runtime error: signed integer overflow: 968551222 * 3 cannot be
represented in type 'int'
/tmp/t.c:13:22: runtime error: signed integer overflow: 1143237676 * 3 cannot
be represented in type 'int'
Looks like it's the * 3 within:
mSeed = mSeed * 3 + 1;
and hence the code is relying on the behavior of that overflow, which
optimization is allowed to change.

gcc8-pr52991.patch
Full untested patch (except for
make check-gcc RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} dg.exp=attr-ms*'
on x86_64-linux), though this really needs to be double-checked against what VC
does, on all the changed testcases.

Hi,

CLANG_ERROR
Unless I missed something from the std::optional specification, we should be
able to use std::optional with std::pair's of integral types. Is this error
actually expected ?
Note: with the implementation from gcc 7 (and libstdc++ shipping with it), this
snippet was accepted (and clang 5 + libstdc++ from gcc 7 was also accepting
it).
Cheers,
Romain

Err, what I meant is that we should reassociate as (index * 8 + x) + CONSTANT.
It seems tree-ssa-reassoc.c avoids reassociating most non-bit expressions by
design (because of signed overflows):
/* For non-bit or min/max operations we can't associate
all types. Verify that here. */
(After the following:
PR tree-optimization/45232
* tree-ssa-reassoc.c (can_reassociate_p): Disable re-association
for types with undefined overflow.
(reassociate_bb): Allow re-associating of bit and min/max
operations for types with undefined overflow.
* tree-ssa-forwprop.c (associate_plusminus): New function.
)
The code that introduced the above, moved some arithmetic reassociation to
reassociate_plusminus() in forwprop, which eventually landed in match.md. So
instead of whacking tree-ssa-reassoc.c to handle POINTER_PLUS_EXPR and
PLUS_EXPR, etc, perhaps we can reassociate from match.pd early in the
compilation process.
So, reassociate:
(ind + 3) * 8 + x
into:
(8*ind + x) + 24
And pray for the best. I'll take a look.

The test cases bf-ms-layout.c and bf-ms-layout-2.c are valid.
You can test it with an online compiler, for example:

The code in comment 13 is irrelevant. You get can the same

--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> ---
If you want some specific machine code for something complex like this, it
is much easier to write the machine code than to fight the compiler.
That said:
1) "flags" is stored in the same register everywhere. This is a problem in
expand: it puts the return value in the same pseudo in the whole function.
This is a bad idea because (if it did not) after optimisation the return
value is just a hard register (r3) and putting all _other_ uses in the same
register is a pessimisation; like here (and in many other cases, there are
other PRs for this!) it causes that pseudo to be put in a callee-save
register (r30).
2) That should be fixed in expand (to enable other optimisations with the
return pseudo), but IRA should also be smarter about live-range splitting
for shrink-wrapping.
3) Separate shrink-wrapping should deal with CRFs. I have a prototype,
it has a few small problems (we need to handle things a little differently
for pretty much every ABI, sigh), and it does not help very much until the
other problems are solved; GCC 9 work);
4) Shrink-wrapping itself could also do more live-range splitting than it
currently does.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
char** and char* are distant types and different with respect to aliasing. So
storing as char* and then loading as char** is undefined behavior. void* is
treated as being able to alias with any other pointer type (like accessing via
the character types).

In testing my patch for bug 83871 I tried to verify that
DECL_DISREGARD_INLINE_LIMITS() is being handled as expected by
duplicate_decls(). I found out that even though the C and C++ front ends try
to handle the limits the -finline-limit option itself is not recognized by
either attribute optimize or #pragma GCC optimize.
Debugging the code shows that the warning is issued by parse_optimize_options()
in response to options that aren't tagged as optimization options. Sure
enough, common.opt doesn't specify Optimization for the option:
finline-limit-
Common RejectNegative Joined Alias(finline-limit=)
finline-limit=
Common RejectNegative Joined UInteger
-finline-limit=<number> Limit the size of inlined functions to
<number>.
$ cat b.c && gcc -O1 -S -Wall -Wextra -finline-limit=16 b.c
#pragma GCC optimize ("inline-functions")
void f0 (void);
#pragma GCC optimize ("align-loops=32")
void f1 (void);
#pragma GCC optimize ("inline-limit=32")
void f2 (void);
void __attribute__ ((optimize ("inline-functions")))
f3(void);
void __attribute__ ((optimize ("inline-limit=100")))

--- Comment #6 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Compare with e.g. the G_BREAKPOINT macro within GNOME's GLib library, which has
accumulated a collection of platform-specific logic for C/C++ code that wants
to inject a breakpoint:
http://git.gnome.org/browse/glib/tree/glib/gbacktrace.h
(LGPLv2+ licensed)
I had a go at adding something similar to CPython:
https://bugs.python.org/issue9635
(albeit for fewer platforms)
It seems useful to have this in either the compiler or in GNU libc.

--- Comment #17 from Jeffrey A. Law <law at redhat dot com> ---
It could well end up being a case where we need to look to see if the
expressions are likely to CSE to determine which is better.
I'm not sure if reassoc has that kind of capability.

--- Comment #18 from Jeffrey A. Law <law at redhat dot com> ---
A couple more notes. It could also well be the case that reassociating in a
way that encourages lea could be good for x86, but bad for other targets.
I also suspect this is closely related to other BZs in the database where we've
regressed due to poor addressing mode selections. If you're able to make
progress here I'll dig them out and we can cross-check your patch against those
other bugs.

--- Comment #4 from Peter Bergner <bergner at gcc dot gnu.org> ---
Actually, I see the vec-setup-be-long.c FAIL even using the revision before
Vlad's commit. The problem seems to be related to PR78303, which is basically
-maltivec=be has issues on LE and instead of fixing them, we've decided to
deprecate -maltivec=be when targeting LE and -maltivec=le when targeting BE, so
I'll look at XFAILing the test on LE.
I agree with Vlad the others are not compiler bugs, but instead are test case
bugs. I haven't decided yet whether to just update the counts or whether to
just remove the scan for xxlor all together, since I doubt we're really
interested in that we generated them at all versus some of the other insns.

--- Comment #19 from Marc Glisse <glisse at gcc dot gnu.org> ---
(In reply to Aldy Hernandez from comment #16)

There have been suggestions that we should do reassoc after some kind of
lowering, where all integer operations wrap, maybe pointer operations are
replaced with integer operations, etc.

--- Comment #31 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Thanks for the hint.
So:
#include <stdio.h>
struct S {
int a : 2;
__declspec(align(8)) int b : 2;
int c : 28;
__declspec(align(16)) int d : 2;
int e : 30;
} s;
int a = sizeof (struct S);
void f1 (int x) { s.a = x; }
void f2 (int x) { s.b = x; }
void f3 (int x) { s.c = x; }
void f4 (int x) { s.d = x; }
void f5 (int x) { s.e = x; }
void
printme (void)
{
int i;
for (i = 0; i < sizeof (s); ++i)
printf ("%02x, ", ((unsigned char *) &s)[i]);
printf ("\n");
}
int
main ()
{
printf ("%d\n", (int) sizeof (s));
s.a = -1; printme ();
s.a = 0; s.b = -1; printme ();
s.b = 0; s.c = -1; printme ();
s.c = 0; s.d = -1; printme ();
s.d = 0; s.e = -1; printme ();
return 0;
}
matches what GCC with the patch emits (that is the bf-ms-layout-5.c test),
and so does:
#include <stddef.h>
#ifdef _WIN32
# ifdef _MSC_VER
# define PACK(typeDec) __pragma( pack(push, 1) ) typeDec __pragma( pack(pop) )
# else
# define PACK(typeDec) typeDec __attribute__((__packed__,ms_struct))
# endif
#else
# define PACK(typeDec) typeDec __attribute__((__packed__))
#endif
#ifdef _MSC_VER
# define ALIGN(typeDec, n) __declspec(align(n)) typeDec
#else
# define ALIGN(typeDec, n) typeDec __attribute__((aligned(n)))
#endif
#define assert_cc(expr) extern char c[(expr) ? 1 : -1]
PACK(struct test_sp1 {
int a;
short b;
int c;
char d;
});
assert_cc(sizeof(struct test_sp1) == 11);
assert_cc(offsetof(struct test_sp1, a) == 0);
assert_cc(offsetof(struct test_sp1, b) == 4);
assert_cc(offsetof(struct test_sp1, c) == 6);
assert_cc(offsetof(struct test_sp1, d) == 10);
PACK(struct test_sp3 {

ALIGN(short b, 8);
int c;
char d;
});
assert_cc(sizeof(struct test_sp3) == 16);
assert_cc(offsetof(struct test_sp3, a) == 0);
assert_cc(offsetof(struct test_sp3, b) == 8);
assert_cc(offsetof(struct test_sp3, c) == 10);
assert_cc(offsetof(struct test_sp3, d) == 14);
struct test_s4 {
int a;
short b;
int c:15;
char d;
};
#ifdef _WIN32
assert_cc(sizeof(struct test_s4) == 16);
assert_cc(offsetof(struct test_s4, a) == 0);
assert_cc(offsetof(struct test_s4, b) == 4);
assert_cc(offsetof(struct test_s4, d) == 12);
#else
assert_cc(sizeof(struct test_s4) == 12);
assert_cc(offsetof(struct test_s4, a) == 0);
assert_cc(offsetof(struct test_s4, b) == 4);
assert_cc(offsetof(struct test_s4, d) == 8);
#endif
int main () { return 0; }

Today I cannot get any ICE's out of this test. Wonder if things were fixed up

verify things are fixed.

Bug ID: 84604
Summary: False positive "may be used uninitialized in this
function" due to variable initialization eliminated as
dead code
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cas43 at cs dot stanford.edu
Target Milestone: ---
WHAT HAPPENS:
The compiler eliminates a=0; and b=0; from the code below during the dce2
optimization pass, resulting in a warning for use of uninitialized variable.
Curiously, the generate code seems to be okay.
OFFENDING CODE:
void f();
struct S
{
int a;
int b;
S()
{
a=0;
b=0;
}
~S()
{
}
void g(int)
{
if(a<10)
{
f();
for(int i=0;i<b;i++){}
this->~S();
a=b+2;
}
}
};
int foo()
{
S s;
s.g(0);
s.g(0);
return s.a+s.b;
}
OPTIMIZED RESULT: (via -fdump-tree-all)
;; Function foo (_Z3foov, funcdef_no=7, decl_uid=2398, cgraph_uid=7,
symbol_order=7)
foo ()
{
int s$b;
int _5;
int _16;
<bb 2> [local count: 1073741825]:
f ();
_16 = s$b_12(D) + 2;
if (_16 <= 9)
goto <bb 4>; [33.00%]
else
goto <bb 3>; [67.00%]
<bb 3> [local count: 1073741827]:
_5 = s$b_12(D) + _16;
return _5;
<bb 4> [local count: 354334802]:
f ();
goto <bb 3>; [100.00%]

--- Comment #8 from Marc Glisse <glisse at gcc dot gnu.org> ---
c_parse_final_cleanups calls handle_tls_init several times in the "do ...
while(reconsider)" loop. With a single static thread_local, we get lucky and
the second time prune_vars_needing_no_initialization returns NULL for an early
exit. Otherwise, the function really doesn't look ready for a second call.
static_aggregates has a more complicated handling than tls_aggregates.

I was under the impression I was allowed to call the destructor just like any
other function. On further investigation, this is undefined behavior, so this
bug report is invalid.

Bug ID: 84607
Summary: Side effects discarded in address computation inside
'if'
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: stephen.dolan at cl dot cam.ac.uk
Target Milestone: ---
This program should print "hello" and "goodbye", but only prints "goodbye":
#include <stdio.h>
int a[10];
int foo() {
puts("hello");
return 0;
}
int main() {
if (&a[foo()])
puts("goodbye");
return 0;
}
I tested locally with gcc 7.2.0 (Debian 7.2.0-19). I also tried the program
with the various gcc versions on godbolt.org, and the problem seems to exist in
all versions since gcc 6 (gcc 5.5 is unaffected). The presence or absence of
-O3 doesn't seem to make a difference.

OK, the original issue still reproduces for the powerpc-e500v2-linux-gnuspe
target as of r257975, so the change that affected this issue must have been
local to the rs6000 backend.
