I'm willing to fix any inappropriate ELF container that will be created with
GCC
or with an other ELF creating tool.

I can imagine bazillion of such corruptions if you do a random mutation of an
ELF
container.

I'm all ears here. What kind of service would run or analyze untrusted ELF
executables?

So we cannot really take the values from the file system for the
buffer size at face value, at least not for determining the buffer size
for this particular case.
Last question (grasping at straws here): Are the values from
comment #24 reproducible, do you always get this big jump for
block size 6553?
If they are indeed reproducible, I would suggest using an approach
slightly modified from the attached patch:
For formatted files, chose the value that the user supplied
via an environment variable, or 8192 otherwise. (Formatted is so
slow that we might as well save the memory).
For formatted files, chose the value that the user supplied
via an environment variable. If the user supplied nothing, then
- query the recommended block size via calling fstat and evaluating
st_blksize.
- If st_blksize is less than 8192, use 8192 (current behavior)
- if st_blksize is more than 32768, use 32768
- otherwise use st_blksize
How does that sound?

--- Comment #4 from ygal klein <ygalklein at gmail dot com> ---
The following code presents a difference (!) between gfortran 8.2 and gfortran
9.1:
program test
implicit none
integer, parameter :: length = 2
real(8), dimension(length) :: a, b
integer :: i
type point
real(8) :: x
end type point
type points
type(point), dimension(:), pointer :: np=>null()
end type points
type stored
integer :: l
type(points), pointer :: nfpoint=>null()
end type stored
type(stored), dimension(:), pointer :: std=>null()
allocate(std(1))
allocate(std(1)%nfpoint)
allocate(std(1)%nfpoint%np(length))
std(1)%nfpoint%np(1)%x = 0.3d0
std(1)%nfpoint%np(2)%x = 0.3555d0
do i = 1, length
write(*, "('std(1)%nfpoint%np(',i1,')%x = ',1e22.14)") i,
std(1)%nfpoint%np(i)%x
end do
do i = 1, length
write(*, "('std(1)%nfpoint%np(1:',i1,')%x = ',2e22.14)") i,
std(1)%nfpoint%np(1:i)%x
end do
a = std(1)%nfpoint%np(1:2)%x
b = [std(1)%nfpoint%np(1)%x, std(1)%nfpoint%np(2)%x]
if (norm2(a - b) .gt. 1d-3) then
write(*,*) 'failure'
else
write(*, *) 'success'
end if
end program test
Running with gfortan-8.2 results with 'success' and running with gfortran-9.1
results with 'failure'.
Removing the integer variable 'l' from the type 'stored' makes both versions
(8.2 and 9.1) end with 'success'
Thanks.

I'm not entirely sure I understand the question correctly but if
you're asking why A::A and A::~A are left untouched in
testsuite/g++.dg/opt/flifetime-dse2.C (on x86_64-linux), that is
because they are not local (the eipa_sra dump even says so).
On a related note, I believe that new IPA-SRA with -flto would also
remove them. It should not be terribly difficult to move/copy
clobbers from a single predecessor of the exit BB to the caller
though.

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: karol.wozniak at linuxmail dot org
Target Milestone: ---
following code sample
template <typename T>
struct numeric_limits;
template<>
struct numeric_limits<long>
{
static constexpr long
max() noexcept { return 0x7fffffffffffffffL; }
};
int main() {
return 42ul > numeric_limits<long>::max();
}
compiled with: g++-9 prog.cc -Wall -Wextra
raises sign-compare warning (https://wandbox.org/permlink/zW28qdCjM3hHPtMd)
but...
- adding optimization: g++-9 prog.cc -Wall -Wextra -O2 -march=native
removes the warning (https://wandbox.org/permlink/Z0GpP3JvunbpKqwO)
- creating helper value to store numeric_limit turns on warning once again in
optimized code (https://wandbox.org/permlink/94s4PEuJLlhKviye)
int main() {
auto m = numeric_limits<long>::max();
return 42ul > m;
}
- making helper value const... removes warning
(https://wandbox.org/permlink/Z0GpP3JvunbpKqwO)
warning was not raised in gcc-8 (https://wandbox.org/permlink/3yKmF2OVJ3FBIPye)

--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Currently full lower_subreg runs only after the first splitter pass.
This is much too late to be effective for this testcase. Running it
before combine (I put it immediately after loop2) works, for all powerpc
configs (32/64, BE/LE, old and new ABI).
It will need more thorough testing, of course. It also should probably
be configurable when the full lower_subreg patch is run (you cannot run
it twice, that generate worse code), I think some ports want it as late
as it is currently?

My lack of knowledge about ia64 is showing...
A ia64-hpux cross from hppa-linux generates the same failing code for the hello
world
program. Thus, I don't think this is a bootstrap compiler problem. It should
be possible
to bisect tree and find the change which broke ia64.
gcc -v should show the configure options used to build original working gcc.

Summary: std namespace symbols can get their visibility

Product: gcc
Version: 9.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46557&action=edit
g++ -fPIC -fvisibility=hidden -E t.cpp
gcc version 9.1.1 20190611 [gcc-9-branch revision 272147] (SUSE Linux)
» cat t.cpp
#include <memory>
class __attribute__((visibility("hidden"))) H {};
class __attribute__((visibility("default"))) V {};
int main()
{
std::make_shared<H>();
std::make_shared<V>();
}
» g++ -fPIC -shared -fvisibility=hidden -o t.so t.cpp
Observed behavior: The two instances of _Sp_ebo_helper<T>::_S_get have
different visibility.
» nm -C t.so | grep _S_get
000000000000582d t std::_Sp_ebo_helper<0, std::allocator<H>,
true>::_S_get(std::_Sp_ebo_helper<0, std::allocator<H>, true>&)
0000000000005810 W std::_Sp_ebo_helper<0, std::allocator<V>,
true>::_S_get(std::_Sp_ebo_helper<0, std::allocator<V>, true>&)
Expected behavior: That the two instances of _S_get have same visibility
(either both t or both W)
» nm -C t.so | grep _S_get
000000000000582d W std::_Sp_ebo_helper<0, std::allocator<H>,...
0000000000005810 W std::_Sp_ebo_helper<0, std::allocator<V>,...
_S_get (t.i:25368) is inside a template struct _Sp_ebo_helper (t.i:25361) which
is inside a "namespace std __attribute__ ((__visibility__ ("default")))"
(t.i:25008), so I would anticipate that the ebo_helper functions are both
global. (Or, if there is a reason I do not see, both local. But never dependent
upon the visibility of a template argument.)

I assume that you meant UNformatted files.
Why are you opposed to the larger 65536 or 131072 as a default? The benefit at
that level is reproducible, _even for filesystems with smaller block size_.
Why propose another default value that restricts GNU FORTRAN performance when
given the opportunity to fix this and make GNU FORTRAN performance look very
good "out of the box". Few people will bother to read the documentation to look
for environment variables or even realize that unformatted I/O performance is
the bottleneck.

Every time these links show up in an email message they get archived and
amplified for posterity. I wonder if that wasn't the actual intent of
the OP given the template-like nature of their messages. A couple
showed up to system accounts on sourceware.org too.
If this needs to be discussed further then I'd suggest not including the
actual links in future followups.
