copied over SHF_MASKOS and SHF_MASKPROC flags. That makes the buggy
code in sh_elf64_copy_private_data_internal redundant.

AVR: Assembler now prepares for linker relaxation by default.
Have the assembler prepare for linker relaxation by default. This
means that users will be able to make use of linker relaxation without
having to adjust the assembler flags, this can make life easier when
compiling libraries.
Having this on by default in the assembler should make no difference to
the assembler code produced, however, some of the debug information will
be slightly less compressed.
A few tests needed to be updated as a result of this change as they
relied on linker relaxation support being off by default.
I've tightened up the definition of which sections can be relaxed on AVR
as part of this commit, the assembler used to think that all
non-debugging sections could be relaxed, when in reality only code
sections can be relaxed for AVR. The previous definition was not
dangerous, just over cautious. The new tighter definition allows an
extra test (gas/testsuite/gas/all/forward.d) to continue to pass.

Don't create .eh_frame_hdr on shared lib bfd
If no object files have .eh_frame, but some shared library does, then
ld creates a .eh_frame_hdr section using the shared library bfd. This
is silly since shared library .eh_frame sections don't contribute to
the output .eh_frame and thus no .eh_frame_hdr is needed.
Also, the bfd section list and count is cleared for shared libraries,
and a zero section count used as a flag in lang_check to omit a call
to bfd_merge_private_bfd_data for shared libraries. If we create a
section on a shared lib bfd then ld will wrongly attempt to merge the
shared library private bfd data.

AVR/ld: Propagate link-relax elf header flag correctly.
The AVR target has an elf header flag to indicate if an object was
assembler ready for linker relaxation. If a partial link is performed
then it is important that the link-relax flag in the output object is
set correctly, otherwise, during the final link, we might try to perform
linker relaxation on code that was not assembled suitably.
As the link-relax elf header covers the entire object file we must be
conservative when setting the flag in the output object, so, for a
partial link, any input object that does not have the link-relax flag
set will cause the output object to also not have the link-relax flag
set.
This conservative approach could be softened in future, we only need to
disable the link relax flag if an input file is not marked link-relax
ready, and the input file contains a relaxable section. However, I've
left this optimisation for a later day.
For the final link I've overloaded the use of the link-relax elf header
flag, in a final executable, the flag now indicates if the executable
was built with linker relaxation on or not.

AVR: Only set link-relax elf flag when appropriate.
The AVR target uses a bit in the elf header flags to indicate if the
object was assembled ready for linker relaxation. Previously this flag
was always set, even when the object was not assembled ready for linker
relaxation.
This patch moves setting of the flag into the assembler, and sets it
only when the assembler is preparing the file for linker relaxation.

gdb/17394: cannot put breakpoint only in selected ASM file.
This patch fixes a problem when trying to insert a breakpoint on
a specific symbol defined in a specific file, eg:
break foo.c:func
This currently works for files in C/C++/Ada, etc, but doesn't always
work for Asm files. Analysis of the problem showed that this related
to a limitation in gas, which does not generate debug info for functions/
symbols. Thus, we have a symtab for the file ("info sources" shows
the file), but it contains no symbols.
When find_linespec_symbols is called in linespec_parse_basic, it calls
find_function_symbols, which uses add_matching_symbols_to_info to
collect all matching symbols.
That function does [pardon any mangled formatting]:
for (ix = 0; VEC_iterate (symtab_ptr, info->file_symtabs, ix, elt); ++ix)
{
if (elt == NULL)
{
iterate_over_all_matching_symtabs (info->state, name, VAR_DOMAIN,
collect_symbols, info,
pspace, 1);
search_minsyms_for_name (info, name, pspace);
}
else if (pspace == NULL || pspace == SYMTAB_PSPACE (elt))
{
/* Program spaces that are executing startup should have
been filtered out earlier. */
gdb_assert (!SYMTAB_PSPACE (elt)->executing_startup);
set_current_program_space (SYMTAB_PSPACE (elt));
iterate_over_file_blocks (elt, name, VAR_DOMAIN,
collect_symbols, info);
}
}
This iterates over the symtabs. In the failing use case, ELT is
non-NULL (points to the symtab for the .s file), so it calls
iterate_over_file_blocks. Herein is where the problem exists: it is
assumed that if NAME exists, it must exist in the given symtab -- a
reasonable assumption for "normal" (non-asm) cases. It never searches
minimal symbols (or in the global default symtab).
This patch fixes the problem by doing so. It is important to note that
iterating over minsyms is fairly expensive, so this patch only adds
that extra search if the language is language_asm and
iterate_over_file_blocks returns no symbols.

Change SometimesInlineFunction to "return i * i * 3;"
The debug_msg test has 2 implementations of SometimesInlineFunction:
int SometimesInlineFunction(int i) { return i; }
int SometimesInlineFunction(int i) { return i * i; }
and One Definition Rule (ODR) violation detection expects they will be
compiled into functions of different sizes. Hower, on x86, GCC 4.7 and
newer compile them into functions of the same size and ODR violation
detection test fails. This patch changes
int SometimesInlineFunction(int i) { return i; }
to
int SometimesInlineFunction(int i) { return i * i * 3; }
so that it will be compiled into a function of larger size.

MIPS: Provide FPU info and decode FCSR in `info float'
This patch is the V2. V1 can be found in
https://sourceware.org/ml/gdb-patches/2012-05/msg00938.html
V2 is to address Joel's comment
<https://sourceware.org/ml/gdb-patches/2012-06/msg00289.html> about
keeping dumping floating point registers. Additionally, command
'info float' prints bits on nan2008 and abs2008.
------------------------------------------------------------------
The change below provides a MIPS-specific handler for the:
(gdb) info float
command. It provides information about the FPU type available (if any),
the FPU register width, and decodes the CP1 Floating Point Control and
Status Register (FCSR):
(gdb) print /x $fsr
$1 = 0xff83ffff
(gdb) info float
fpu type: double-precision
reg size: 32 bits
cond : 0 1 2 3 4 5 6 7
cause : inexact uflow oflow div0 inval unimp
mask : inexact uflow oflow div0 inval
flags : inexact uflow oflow div0 inval
rounding: -inf
flush : zero
One point to note about CP1.FCSR are the non-standard Flush-to-Nearest
and Flush-Override bits. They are not a part of the MIPS architecture and
take two positions reserved for an implementation-dependent use in the
architecture. They are present in all the FPU implementations made by
MIPS Technologies since the spin-off from SGI.
I haven't been able to track down a single other MIPS FPU implementation
that would make any use of these bits and they are required to be
hardwired to zero by the architecture specification if unimplemented.
Therefore I think it makes sense to report them in the current way.
GDB has no guaranteed access to the CP0 Processor Identification (PRId)
register to validate this feature properly and the ID information stored
in the CP1 Floating Point Implementation Register (FIR) is from my
experience not reliable enough (there's no Company ID available there for
once unlike in CP0.PRId and Processor ID is not guaranteed to be unique).
As a side note we should probably dump CP1.FIR information as well, as
there's useful stuff indicating some FPU features there. That's material
for another change however.

Refactor gdbarch method print_float_info
This patch is to change print_float_info gdbarch method for the
following two reasons,
1. we want to add a default implementation of print_float_info to

print something more than float point registers.
2. we want to simplify the caller of print_float_info,

cc1: all warnings being treated as errors
In the end I have managed to test it by Wine myself:
$ wine build_win32/gdb/gdb.exe -q build_win32/gdb/gdb.exe -ex start -ex 'compile code 1' -ex 'set confirm no' -ex quit
[...]
Temporary breakpoint 1, main (argc=1, argv=0x241418) at ../../gdb/gdb.c:29
29 args.argc = argc;
Could not load libcc1.so: Module not found.
Even if it managed to load libcc1.so (it needs host-dependent name libcc1.dll)
then it would soon end up at least on:
default_infcall_mmap:
error (_("This target does not support inferior memory allocation by mmap."));
As currently there is only:
linux-tdep.c:
set_gdbarch_infcall_mmap (gdbarch, linux_infcall_mmap);
While one could debug Linux targets from MS-Windows host I find it somehow
overcomplicated now when we are trying to get it running at least on native
Linux x86*.
The 'compile' project needs a larger port effort to run on MS-Windows.

value_maybe_namespace_elt: Remove redundant call to lookup_static_symbol.
Anytime you can remove a symbol lookup that loops over all objfiles
is A Good Thing.
The call to lookup_static_symbol in valops.c:value_maybe_namespace_elt
is redundant with this call in cp_lookup_nested_symbol:
/* Now search all static file-level symbols. We have to do this
for things like typedefs in the class. We do not try to
guess any imported namespace as even the fully specified
namespace search is already not C++ compliant and more
assumptions could make it too magic. */
size = strlen (parent_name) + 2 + strlen (nested_name) + 1;
concatenated_name = alloca (size);
xsnprintf (concatenated_name, size, "%s::%s",
parent_name, nested_name);
sym = lookup_static_symbol (concatenated_name, VAR_DOMAIN);
if (sym != NULL)
return sym;
Earlier in value_maybe_namespace_elt we do this:
sym = cp_lookup_symbol_namespace (namespace_name, name,
get_selected_block (0), VAR_DOMAIN);
That sequence goes like:
value_maybe_namespace_elt
-> cp_lookup_symbol_namespace
-> cp_lookup_symbol_in_namespace
-> lookup_symbol_file
-> cp_lookup_nested_symbol
-> lookup_static_symbol
The call was added in commit 41f62f3939b1c69e68ef5652feb44fef90eb85c9.
https://sourceware.org/ml/gdb-patches/2010-06/msg00663.html
With a part 2 here:
https://sourceware.org/ml/gdb-patches/2010-06/msg00664.html
At the time the call to lookup_static_symbol (spelled
lookup_static_symbol_aux at the time) was needed.
However, this patch, 8dea366bbed7986295681c101dcfbd35aeb6dfc4,
https://sourceware.org/ml/gdb-patches/2012-11/msg00387.html
augmented lookup_symbol_file to call cp_lookup_nested_symbol
and introduced the redundancy.
It's kinda buried, so it's totally not unexpected that this happened.

Fix indentation of "maint print user-registers"
This fixes a failure of the test case "complete 'info registers '" in
completion.exp on architectures where the user registers have numbers
above 99. In that case the output of "maint print user-registers" was
no longer indented, and the regexp in the test case failed to add them
to the list of expected completion results. The fix also swaps the
columns "Name" and "Nr", such that the indentation is always the same,
and to be consistent with the output of "maint print registers".

[Linux] Ask kernel to kill inferior when GDB terminates
This patch enhances GDB on GNU/Linux systems in the situation where
we are debugging an inferior that was created from GDB (as opposed
to attached to), by asking the kernel to kill the inferior if GDB
terminates without doing it itself.
This would typically happen when GDB encounters a problem and
crashes, or when it gets killed by an external process. This can
be observed by starting a program under GDB, and then killing
GDB with signal 9. After GDB is killed, the inferior still remains.
This patch also fixes GDBserver similarly.
This fix is conditional on the kernel supporting the PTRACE_O_EXITKILL
feature. On older kernels, the behavior remains unchanged.
gdb/ChangeLog:
* nat/linux-ptrace.h (PTRACE_O_EXITKILL): Define if not
already defined.
(linux_enable_event_reporting): Add parameter "attached".
* nat/linux-ptrace.c (linux_test_for_exitkill): New forward
declaration. New function.
(linux_check_ptrace_features): Add linux_test_for_exitkill call.
(linux_enable_event_reporting): Add new parameter "attached".
Do not call ptrace with the PTRACE_O_EXITKILL if ATTACHED is
nonzero.
* linux-nat.c (linux_init_ptrace): Add parameter "attached".
Use it. Update function description.
(linux_child_post_attach, linux_child_post_startup_inferior):
Update call to linux_enable_event_reporting.
gdb/gdbserver/ChangeLog:
* linux-low.c (linux_low_filter_event): Update call to
linux_enable_event_reporting following the addition of
a new parameter to that function.
Tested on x86_64-linux, native and native-gdbserver.
I also verified by hand that the inferior gets killed when killing
GDB in the "run" case, while the inferior remains in the "attach"
case. Same for GDBserver.

Merge dg-extract-results.{sh,py} from GCC upstream
It has been a while since we don't sync this file with GCC upstream,
and in the meantime some interesting things have happened. The most

testsuite: expect possible pagination when starting gdb
When gdb starts, the lines that appear before the first prompt may get
paginated if the terminal in which the tests are ran is too small (in
terms of rows). These lines include the welcome/license message and
possibly more, such as "Reading symbols from...". Pagination is disabled
right after gdb is started (with "set height 0"), but this output happens
before we are able to set height.
If these lines get paginated, gdb waits for the user to press enter and
the test harness waits for gdb to print its prompt, resulting in a
deadlock.
My first idea was to launch gdb with --quiet. However, some lines are
still printed ("Reading symbols from...", some more stuff when attaching
with --pid, etc).
The proposed solution simply expects that pagination can occur after
starting gdb. If this is the case, it sends a "\n" and loops.
gdb/testsuite/Changelog:
* lib/gdb.exp (default_gdb_start): After starting gdb, loop
as long as we get pagination notifications.

Fix build with Python 3.4 (PR python/16784)
The type of the function pointer PyOS_ReadlineFunctionPointer (part of the
Python C API), which we use, slightly changed starting with Python 3.4. The
signature went from
PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *);
to
PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *);
The parameter that changed is the prompt text.
This commits adjust gdb accordingly by making the prompt_arg parameter
const, as well as the fallouts of that. I needed to rework how
annotations are added to the prompt, since the it is now const. If
annotations are enabled, it will make a copy of the prompt overwrite the
prompt variable that is used throughout the function. Otherwise, no copy
is done and the original prompt_arg value is passed.
I changed the signature of deprecated_readline_hook. I would've changed any
user of it, but it seems like nothing is using it,
Built-tested with python 2.7.x, 3.3.y and 3.4.z.
gdb/ChangeLog:
* defs.h (gdb_readline): Constify argument.
(gdb_readline_wrapper): Same.
(command_line_input): Same.
(deprecated_readline_hook): Same.
* top.c (deprecated_readline_hook): Same.
(gdb_readline): Same.
(gdb_readline_wrapper): Same.
(command_line_input): Constify argument. Pass prompt to
called functions instead of local_prompt, overwriting prompt
if using annotations.
* event-top.h (display_gdb_prompt): Constify argument.
* event-top.c (display_gdb_prompt): Same.
* python/py-gdb-readline.c (gdbpy_readline_wrapper): Constify

python extended prompt: Use os.getcwd() instead of os.getcwdu()
It seems like using os.getcwdu() here is wrong both for Python 2 and Python 3.
For Python 2, this returns a 'unicode' object, which tries to get concatenated
to a 'str' object in substitute_prompt. The implicit conversion works when the
unicode string contains no accent. When it does contain an accent though,
displaying the prompt results in the following error:
(gdb) set extended-prompt \w
...
File "/home/simark/build/binutils-gdb-python2/gdb/data-directory/python/gdb/prompt.py", line 138, in substitute_prompt
result += str(cmd(arg))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 49: ordinal not in range(128)

Use PTRACE_SINGLESTEP_ONE when single-stepping one thread.
Currently, when we receive a request to single-step one single thread
(Eg, when single-stepping out of a breakpoint), we use the
PTRACE_SINGLESTEP pthread request, which does single-step
the corresponding thread, but also resumes execution of all
other threads in the inferior.
This causes problems when debugging programs where another thread
receives multiple debug events while trying to single-step a specific
thread out of a breakpoint (with infrun traces turned on):

What happens is that GDB keeps sending requests to resume one specific
thread, and keeps receiving debugging events for other threads.
Things break down when the one of the other threads receives a debug
event for the second time (thread 146 in the example above).
This patch fixes the problem by making sure that only one thread
gets resumed, thus preventing the other threads from generating
an unexpected event.

Internal error trying to print uninitialized string.
Trying to print the value of a string whose size is not known at
compile-time before it gets assigned a value can lead to the following
internal error:
(gdb) p my_str
$1 =
/[...]/utils.c:1089: internal-error: virtual memory exhausted.
What happens is that my_str is described as a reference to an array
type whose bounds are dynamic. During the read of that variable's
value (in default_read_var_value), we end up resolving dynamic types
which, for reference types, makes us also resolve the target of that
reference type. This means we resolve our variable to a reference
to an array whose bounds are undefined, and unfortunately very far
appart.
So, when we pass that value to ada-valprint, and in particular to
da_val_print_ref, we eventually try to allocate too large of a buffer
corresponding to the (bogus) size of our array, hence the internal
error.
This patch fixes the problem by adding a size_check before trying
to print the dereferenced value. To perform this check, a function
that was previously specific to ada-lang.c (check_size) gets
exported, and renamed to something less prone to name collisions
(ada_ensure_varsize_limit).

configure gdb/gnulib with --disable-largefile if largefile support disabled.
This patch mostly aims at fixing a GDB build failure on 32bit Solaris
systems (Sparc and x86), due to a recent gnulib update adding the
readlink module. But it might also fix related issues when configuring
with --disable-largefile.
A side-effect of the gnulib readlink module addition is that it caused
largefile support to be added as well, and in particular
gnulib/import/m4/largefile.m4 introduced the following new #define in
gnulib's config.in:
| +/* Number of bits in a file offset, on hosts where this is settable. */
| +#undef _FILE_OFFSET_BITS
When defined to 64, it triggers an issue with procfs.h while trying
to build sparc-sol2-nat.c:
| #if !defined(_LP64) && _FILE_OFFSET_BITS == 64
| #error "Cannot use procfs in the large file compilation environment"
| #endif
As it turns out, this is a fairly familiar problem, and one of
the reasons behind ACX_LARGEFILE having been created. In that macro,
we have some code which disables largefile support on solaris hosts:
| sparc-*-solaris*|i[3-7]86-*-solaris*)
| changequote([,])dnl
| # On native 32bit sparc and ia32 solaris, large-file and procfs support
| # are mutually exclusive; and without procfs support, the bfd/ elf module
| # cannot provide certain routines such as elfcore_write_prpsinfo
| # or elfcore_write_prstatus. So unless the user explicitly requested
| # large-file support through the --enable-largefile switch, disable
| # large-file support in favor of procfs support.
| test "${target}" = "${host}" -a "x$plugins" = xno \
| && : ${enable_largefile="no"}
| ;;
But gnulib ignores this fact, and so tries to determine how to
enable large-file support irrespective of whether we want it or not.
This patch fixes the issue by passing --disable-largefile to gnulib's
configure when large-file support in GDB is disabled. This is done
by first enhancing ACX_CONFIGURE_DIR to allow us to pass extra
arguments to be passed to the configure command, and then by modifying
GDB's configure to pass --disable-largefile if large-file support
is disabled.
gdb/ChangeLog:
* acx_configure_dir.m4 (ACX_CONFIGURE_DIR): Add support for
new "EXTRA-ARGS" parameter.
* configure.ac: If large-file support is disabled in GDB,
pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib".
* configure: Regenerate.
gdb/gdbserver/ChangeLog:
* configure.ac: If large-file support is disabled in GDBserver,
pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib".
* configure: Regenerate.
Tested by rebuilding on sparc-solaris and x86_64-linux (with gdbserver).
This fixes the build failure on sparc-solaris. I also verified in
gnulib's config.log file that we pass --disable-largefile in the solaris
case, while we do not in the GNU/Linux case.

Lift DWARF unwinder restriction in dwarf2-frame.c::dwarf2_frame_cfa
GDB is currently broken on all SPARC targets when using GCC 4.9.
When trying to print any local variable:
(gdb) p x
can't compute CFA for this frame
This is related to the fact that the compiler now generates DWARF 4
debugging info by default, and in particular that it now emits
DW_OP_call_frame_cfa, which triggers a limitation in dwarf2_frame_cfa:
/* This restriction could be lifted if other unwinders are known to
compute the frame base in a way compatible with the DWARF
unwinder. */
if (!frame_unwinder_is (this_frame, &dwarf2_frame_unwind)
&& !frame_unwinder_is (this_frame, &dwarf2_tailcall_frame_unwind))
error (_("can't compute CFA for this frame"));
We couldn't append the dwarf2 unwinder to all SPARC targets because
it does not work properly with StackGhost:
https://www.sourceware.org/ml/gdb-patches/2014-07/msg00012.html
We also later discovered that using the DWARF2 unwinder means
using it for computing the function's return address, which
is buggy when it comes to functions returning a struct (where
the return address is saved-pc+12 instead of saved-pc+8).
This is because GCC is emitting the info about the return address
as %o7/%i7 instead of the actual return address. For functions
that have debugging info, we compensate by looking at the function's
return type and add the extra +4, but for function without debug
info, we're stuck.
EricB and I twisted the issue in all the directions we could think of,
and unfortunately couldn't find a way to make it work without
introduction one regression or another.
But, stepping back a little, just removing the restriction seems to work
well for us on all both sparc-elf and {sparc,sparc64}-solaris.
After reviewing the previous discussions about this test, I could
not figure out whether some unwinders were already known to have
incompatible CFAs or if the concern was purely theoretical:
https://www.sourceware.org/ml/gdb-patches/2009-06/msg00191.html
https://www.sourceware.org/ml/gdb-patches/2009-07/msg00570.html
https://www.sourceware.org/ml/gdb-patches/2009-09/msg00027.html
At the moment, we took the approach of trying it out, and see what
happens...

the "compile" command
This final patch adds the new "compile" command and subcommands, and
all the machinery needed to make it work.
A shared library supplied by gcc is used for all communications with
gcc. Types and most aspects of symbols are provided directly by gdb
to the compiler using this library.
gdb provides some information about the user's code using plain text.
Macros are emitted this way, and DWARF location expressions (and
bounds for VLA) are compiled to C code.
This hybrid approach was taken because, on the one hand, it is better
to provide global declarations and such on demand; but on the other
hand, for local variables, translating DWARF location expressions to C
was much simpler than exporting a full compiler API to gdb -- the same
result, only easier to implement, understand, and debug.
In the ordinary mode, the user's expression is wrapped in a dummy
function. After compilation, gdb inserts the resulting object code
into the inferior, then calls this function.
Access to local variables is provided by noting which registers are
used by location expressions, and passing a structure of register
values into the function. Writes to registers are supported by
copying out these values after the function returns.
This approach was taken so that we could eventually implement other
more interesting features based on this same infrastructure; for
example, we're planning to investigate inferior-side breakpoint
conditions.

add gnu_triplet_regexp gdbarch method
gdb has to inform libcc1.so of the target being used, so that the
correct compiler can be invoked. The compiler is invoked using the
GNU configury triplet prefix, e.g., "x86_64-unknown-linux-gnu-gcc".
In order for this to work we need to map the gdbarch to the GNU
configury triplet arch. In most cases these are identical; however,
the x86 family poses some problems, as the BFD arch names are quite
different from the GNU triplet names. So, we introduce a new gdbarch
method for this. A regular expression is used because there are
various valid values for the arch prefix in the triplet.
This patch also updates the osabi code to associate a regular
expression with the OS ABI. I have only added a concrete value for
Linux. Note that the "-gnu" part is optional, at least on Fedora it
is omitted from the installed GCC executable's name.

add gcc/gdb interface files
The gcc plugin is split into two parts. One part is an ordinary gcc
plugin. The other part is a shared library that is loaded by gdb.
This patch adds some files that define the interface exported by this
shared library to gdb. These files also define the internal API by
which the gdb- and gcc-sides communicate.
These files will be kept in sync between gcc and gdb like much of
include/.
The exported API has been intentionally kept very simple. In
particular only a single function is exported from the gdb-side
library; symbol visibility is used to hide everything else. This
exported symbol is a function which is called to return a structure
holding function pointers that gdb then uses. This structure is
versioned so that changes can be made without necessarily requiring a
simultaneous gdb upgrade.
Note that the C compiler API is broken out separately. This lets us
extend it to other GCC front ends as desired. We plan to investigate
C++ in the future.

MIPS: Keep the ISA bit in compressed code addresses
1. Background information
The MIPS architecture, as originally designed and implemented in
mid-1980s has a uniform instruction word size that is 4 bytes, naturally
aligned. As such all MIPS instructions are located at addresses that
have their bits #1 and #0 set to zeroes, and any attempt to execute an
instruction from an address that has any of the two bits set to one
causes an address error exception. This may for example happen when a
jump-register instruction is executed whose register value used as the
jump target has any of these bits set.
Then in mid 1990s LSI sought a way to improve code density for their
TinyRISC family of MIPS cores and invented an alternatively encoded
instruction set in a joint effort with MIPS Technologies (then a
subsidiary of SGI). The new instruction set has been named the MIPS16
ASE (Application-Specific Extension) and uses a variable instruction
word size, which is 2 bytes (as the name of the ASE suggests) for most,
but there are a couple of exceptions that take 4 bytes, and then most of
the 2-byte instructions can be treated with a 2-byte extension prefix to
expand the range of the immediate operands used.
As a result instructions are no longer 4-byte aligned, instead they are
aligned to a multiple of 2. That left the bit #0 still unused for code
references, be it for the standard MIPS (i.e. as originally invented) or
for the MIPS16 instruction set, and based on that observation a clever
trick was invented that on one hand allowed the processor to be
seamlessly switched between the two instruction sets at any time at the
run time while on the other avoided the introduction of any special
control register to do that.
So it is the bit #0 of the instruction address that was chosen as the
selector and named the ISA bit. Any instruction executed at an even
address is interpreted as a standard MIPS instruction (the address still
has to have its bit #1 clear), any instruction executed at an odd
address is interpreted as a MIPS16 instruction.
To switch between modes ordinary jump instructions are used, such as
used for function calls and returns, specifically the bit #0 of the
source register used in jump-register instructions selects the execution
(ISA) mode for the following piece of code to be interpreted in.
Additionally new jump-immediate instructions were added that flipped the
ISA bit to select the opposite mode upon execution. They were
considered necessary to avoid the need to make register jumps in all
cases as the original jump-immediate instructions provided no way to
change the bit #0 at all.
This was all important for cases where standard MIPS and MIPS16 code had
to be mixed, either for compatibility with the existing binary code base
or to access resources not reachable from MIPS16 code (the MIPS16
instruction set only provides access to general-purpose registers, and
not for example floating-point unit registers or privileged coprocessor
0 registers) -- pieces of code in the opposite mode can be executed as
ordinary subroutine calls.
A similar approach has been more recently adopted for the MIPS16
replacement instruction set defined as the so called microMIPS ASE.
This is another instruction set encoding introduced to the MIPS
architecture. Just like the MIPS16 ASE, the microMIPS instruction set
uses a variable-length encoding, where each instruction takes a multiple
of 2 bytes. The ISA bit has been reused and for microMIPS-capable
processors selects between the standard MIPS and the microMIPS mode
instead.
2. Statement of the problem
To put it shortly, MIPS16 and microMIPS code pointers used by GDB are
different to these observed at the run time. This results in the same
expressions being evaluated producing different results in GDB and in
the program being debugged. Obviously it's the results obtained at the
run time that are correct (they define how the program behaves) and
therefore by definition the results obtained in GDB are incorrect.
A bit longer description will record that obviously at the run time the
ISA bit has to be set correctly (refer to background information above
if unsure why so) or the program will not run as expected. This is
recorded in all the executable file structures used at the run time: the
dynamic symbol table (but not always the static one!), the GOT, and
obviously in all the addresses embedded in code or data of the program
itself, calculated by applying the appropriate relocations at the static
link time.
While a program is being processed by GDB, the ISA bit is stripped off
from any code addresses, presumably to make them the same as the
respective raw memory byte address used by the processor to access the
instruction in the instruction fetch access cycle. This stripping is
actually performed outside GDB proper, in BFD, specifically
_bfd_mips_elf_symbol_processing (elfxx-mips.c, see the piece of code at
the very bottom of that function, starting with an: "If this is an
odd-valued function symbol, assume it's a MIPS16 or microMIPS one."
comment).
This function is also responsible for symbol table dumps made by
`objdump' too, so you'll never see the ISA bit reported there by that
tool, you need to use `readelf'.
This is however unlike what is ever done at the run time, the ISA bit
once present is never stripped off, for example a cast like this:
(short *) main
will not strip the ISA bit off and if the resulting pointer is intended
to be used to access instructions as data, for example for software
instruction decoding (like for fault recovery or emulation in a signal
handler) or for self-modifying code then the bit still has to be
stripped off by an explicit AND operation.
This is probably best illustrated with a simple real program example.
Let's consider the following simple program:
$ cat foobar.c
int __attribute__ ((mips16)) foo (void)
{
return 1;
}
int __attribute__ ((mips16)) bar (void)
{
return 2;
}
int __attribute__ ((nomips16)) foo32 (void)
{
return 3;
}
int (*foo32p) (void) = foo32;
int (*foop) (void) = foo;
int fooi = (int) foo;
int
main (void)
{
return foop ();
}
$
This is plain C with no odd tricks, except from the instruction mode
attributes. They are not necessary to trigger this problem, I just put
them here so that the program can be contained in a single source file
and to make it obvious which function is MIPS16 code and which is not.
Let's try it with Linux, so that everyone can repeat this experiment:
$ mips-linux-gnu-gcc -mips16 -g -O2 -o foobar foobar.c
$
Let's have a look at some interesting symbols:
$ mips-linux-gnu-readelf -s foobar | egrep 'table|foo|bar'
Symbol table '.dynsym' contains 7 entries:
Symbol table '.symtab' contains 95 entries:
55: 00000000 0 FILE LOCAL DEFAULT ABS foobar.c

Hmm, no sight of the ISA bit, but notice how foo and bar (but not
foo32!) have been marked as MIPS16 functions (ELF symbol structure's
`st_other' field is used for that).
So let's try to run and poke at this program with GDB. I'll be using a
native system for simplicity (I'll be using ellipses here and there to
remove unrelated clutter):
$ ./foobar
$ echo $?
1
$
So far, so good.
$ gdb ./foobar
[...]
(gdb) break main
Breakpoint 1 at 0x400490: file foobar.c, line 23.
(gdb) run
Starting program: .../foobar
Breakpoint 1, main () at foobar.c:23
23 return foop ();
(gdb)
Yay, it worked! OK, so let's poke at it:
(gdb) print main
$1 = {int (void)} 0x400490 <main>
(gdb) print foo32
$2 = {int (void)} 0x400684 <foo32>
(gdb) print foo32p
$3 = (int (*)(void)) 0x400684 <foo32>
(gdb) print bar
$4 = {int (void)} 0x40068c <bar>
(gdb) print foo
$5 = {int (void)} 0x400680 <foo>
(gdb) print foop
$6 = (int (*)(void)) 0x400681 <foo>
(gdb)
A-ha! Here's the difference and finally the ISA bit!
(gdb) print /x fooi
$7 = 0x400681
(gdb) p/x $pc
p/x $pc
$8 = 0x400491
(gdb)
And here as well...
(gdb) advance foo
foo () at foobar.c:4

(gdb) disassemble

(gdb) finish
Run till exit from #0 foo () at foobar.c:4
main () at foobar.c:24
24 }
Value returned is $9 = 1
(gdb) continue
Continuing.
[Inferior 1 (process 14103) exited with code 01]
(gdb)
So let's be a bit inquisitive...
(gdb) run
Starting program: .../foobar
Breakpoint 1, main () at foobar.c:23
23 return foop ();
(gdb)
Actually we do not like to run foo here at all. Let's run bar instead!
(gdb) set foop = bar
(gdb) print foop
$10 = (int (*)(void)) 0x40068c <bar>
(gdb)
Hmm, no ISA bit. Is it going to work?
(gdb) advance bar
bar () at foobar.c:9
9 }
(gdb) p/x $pc
$11 = 0x40068c
(gdb) disassemble

(gdb)
Oops!
(gdb) p/x $pc
$12 = 0x40068c
(gdb)
We're still there!
(gdb) continue
Continuing.
Program terminated with signal SIGILL, Illegal instruction.
The program no longer exists.
(gdb)
So let's try something else:
(gdb) run
Starting program: .../foobar
Breakpoint 1, main () at foobar.c:23
23 return foop ();
(gdb) set foop = foo
(gdb) advance foo
foo () at foobar.c:4

(gdb) disassemble

Run till exit from #0 foo () at foobar.c:4
Program received signal SIGILL, Illegal instruction.
foo () at foobar.c:4
4 }
(gdb) continue
Continuing.
Program terminated with signal SIGILL, Illegal instruction.
The program no longer exists.
(gdb)
The same problem!
(gdb) run
Starting program:

Breakpoint 1, main () at foobar.c:23
23 return foop ();
(gdb) set foop = foo32
(gdb) advance foo32
foo32 () at foobar.c:14
14 }
(gdb) disassemble

Run till exit from #0 foo32 () at foobar.c:14
main () at foobar.c:24
24 }
Value returned is $14 = 3
(gdb) continue
Continuing.
[Inferior 1 (process 14113) exited with code 03]
(gdb)
That did work though, so it's the ISA bit only!
(gdb) quit
Enough!
That's the tip of the iceberg only though. So let's rebuild the
executable with some dynamic symbols:
$ mips-linux-gnu-gcc -mips16 -Wl,--export-dynamic -g -O2 -o foobar-dyn foobar.c
$ mips-linux-gnu-readelf -s foobar-dyn | egrep 'table|foo|bar'
Symbol table '.dynsym' contains 32 entries:
6: 004009cd 4 FUNC GLOBAL DEFAULT 12 bar
8: 00410b88 4 OBJECT GLOBAL DEFAULT 21 foo32p
9: 00410b84 4 OBJECT GLOBAL DEFAULT 21 foop
15: 004009c4 8 FUNC GLOBAL DEFAULT 12 foo32
17: 004009c1 4 FUNC GLOBAL DEFAULT 12 foo
25: 00410b80 4 OBJECT GLOBAL DEFAULT 21 fooi
Symbol table '.symtab' contains 95 entries:
55: 00000000 0 FILE LOCAL DEFAULT ABS foobar.c
69: 004009cd 4 FUNC GLOBAL DEFAULT 12 bar
71: 00410b88 4 OBJECT GLOBAL DEFAULT 21 foo32p
72: 00410b84 4 OBJECT GLOBAL DEFAULT 21 foop

81: 004009c1 4 FUNC GLOBAL DEFAULT 12 foo
89: 00410b80 4 OBJECT GLOBAL DEFAULT 21 fooi
$
OK, now the ISA bit is there for a change, but the MIPS16 `st_other'
attribute gone, hmm... What does `objdump' do then:
$ mips-linux-gnu-objdump -Tt foobar-dyn | egrep 'SYMBOL|foo|bar'
foobar-dyn: file format elf32-tradbigmips
SYMBOL TABLE:

$
Hmm, the attribute (0xf0, printed raw) is back, and the ISA bit gone
again.

-- a-ha, the ISA bit is there! However it's not always right for some
reason, I don't have a small test case to show it, but here's an excerpt

-- see that "Advance PC by constant 17" there? It clears the ISA bit,
however code at 0x19646 is not standard MIPS code at all. For some
reason the constant is always 17, I've never seen DW_LNS_const_add_pc
used with any other value -- is that a binutils bug or what?
3. Solution:
I think we should retain the value of the ISA bit in code references,
that is effectively treat them as cookies as they indeed are (although
trivially calculated) rather than raw memory byte addresses.
In a perfect world both the static symbol table and the respective
DWARF-2 records should be fixed to include the ISA bit in all the cases.
I think however that this is infeasible.
All the uses of `_bfd_mips_elf_symbol_processing' can not necessarily be
tracked down. This function is used by `elf_slurp_symbol_table' that in
turn is used by `bfd_canonicalize_symtab' and
`bfd_canonicalize_dynamic_symtab', which are public interfaces.
Similarly DWARF-2 records are used outside GDB, one notable if a bit
questionable is the exception unwinder (libgcc/unwind-dw2.c) -- I have
identified at least bits in `execute_cfa_program' and
`uw_frame_state_for', both around the calls to `_Unwind_IsSignalFrame',
that would need an update as they effectively flip the ISA bit freely;
see also the comment about MASK_RETURN_ADDR in gcc/config/mips/mips.h.
But there may be more places. Any change in how DWARF-2 records are
produced would require an update there and would cause compatibility
problems with libgcc.a binaries already distributed; given that this is
a static library a complex change involving function renames would
likely be required.
I propose therefore to accept the existing inconsistencies and deal with
them entirely within GDB. I have figured out that the ISA bit lost in
various places can still be recovered as long as we have symbol
information -- that'll have the `st_other' attribute correctly set to
one of standard MIPS/MIPS16/microMIPS encoding.
Here's the resulting change. It adds a couple of new `gdbarch' hooks,
one to update symbol information with the ISA bit lost in
`_bfd_mips_elf_symbol_processing', and two other ones to adjust DWARF-2
records as they're processed. The ISA bit is set in each address
handled according to information retrieved from the symbol table for the
symbol spanning the address if any; limits are adjusted based on the
address they point to related to the respective base address.
Additionally minimal symbol information has to be adjusted accordingly
in its gdbarch hook.
With these changes in place some complications with ISA bit juggling in
the PC that never fully worked can be removed from the MIPS backend.
Conversely, the generic dynamic linker event special breakpoint symbol
handler has to be updated to call the minimal symbol gdbarch hook to
record that the symbol is a MIPS16 or microMIPS address if applicable or
the breakpoint will be set at the wrong address and either fail to work
or cause SIGTRAPs (this is because the symbol is handled early on and
bypasses regular symbol processing).
4. Results obtained
The change fixes the example above -- to repeat only the crucial steps:
(gdb) break main
Breakpoint 1 at 0x400491: file foobar.c, line 23.
(gdb) run
Starting program: .../foobar
Breakpoint 1, main () at foobar.c:23
23 return foop ();
(gdb) print foo
$1 = {int (void)} 0x400681 <foo>
(gdb) set foop = bar
(gdb) advance bar
bar () at foobar.c:9
9 }
(gdb) disassemble
Dump of assembler code for function bar:
=> 0x0040068d <+0>: jr ra
0x0040068f <+2>: li v0,2
End of assembler dump.
(gdb) finish
Run till exit from #0 bar () at foobar.c:9
main () at foobar.c:24
24 }
Value returned is $2 = 2
(gdb) continue
Continuing.
[Inferior 1 (process 14128) exited with code 02]
(gdb)
-- excellent!
The change removes about 90 failures per MIPS16 multilib in mips-sde-elf
testing too, results for MIPS16 are now similar to that for standard
MIPS; microMIPS results are a bit worse because of host-I/O problems in
QEMU used instead of MIPSsim for microMIPS testing only:

S390: Fix gdbserver support for TDB
This makes gdbserver actually provide values for the TDB registers
when the inferior was stopped in a transaction. The change in
linux-low.c is needed to suppress the warning for an unavailable TDB.
The test case 's390-tdbregs.exp' passes with this patch and fails
without.

* linux-low.c (regsets_fetch_inferior_registers): Suppress the
warning upon ENODATA from ptrace.
* linux-s390-low.c (s390_store_tdb): New.

gdbserver: Support read-only regsets in linux-low.c
For GNU/Linux targets using the regsets interface, this change
supports regsets that can be read but not written. The S390 "last
break" regset is an example. So far it had been defined with
regset->set_request == PTRACE_GETREGSET, such that the respective
ptrace call does not cause any harm. Now we just skip the whole
read/modify/write sequence for regsets that do not define a
fill_function.
gdb/gdbserver/ChangeLog:
* linux-low.c (regsets_store_inferior_registers): Skip regsets
without a fill_function.
* linux-s390-low.c (s390_fill_last_break): Remove.
(s390_regsets): Set fill_function to NULL for NT_S390_LAST_BREAK.

gdbserver: Prevent stale/random values in register cache
When fetch_inferior_registers does not update all registers, this
patch assures that no stale register values remain in the register
cache. On Linux platforms using the regsets interface, when one of
the ptrace calls used for fetching the register values returns an
error, this patch also avoids copying the random data returned from
ptrace into the register cache. All unfetched registers are marked
"unavailable" instead.
gdb/gdbserver/ChangeLog:
* linux-low.c (regsets_fetch_inferior_registers): Do not invoke
the regset's store function when ptrace returned an error.
* regcache.c (get_thread_regcache): Invalidate register cache
before fetching inferior's registers.

gdbserver: Rephrase loops in regsets_fetch/store_inferior_registers
Replace the while-loops in linux-low.c that iterate over regsets by
for-loops. This makes it clearer what is iterated over. Also, since
"continue" now moves on to the next iteration without having to
increment the regset pointer first, the code is slightly reduced.
In case of EIO the old code did not increment the regset pointer, but
iterated over the same (now disabled) regset again. This extra
iteration is now avoided.

Copy relocations against protected symbols
Copy relocs are used in a scheme to avoid dynamic text relocations in
non-PIC executables that refer to variables defined in shared
libraries. The idea is to have the linker define any such variable in
the executable, with a copy reloc copying the initial value, then have
both the executable and shared library refer to the executable copy.
If the shared library defines the variable as protected then we have
two copies of the variable being used.

Improve arm_skip_prologue by using arm_analyze_prologue
Hi,
I see many fails in dw2-dir-file-name.exp on arm target when test
case is compiled with -marm, however, these fails are disappeared when
test case is compiled with -mthumb.
The difference of pass and fail shown below is that "0x000085d4 in" isn't
printed out, but test case expects to see it.
-Breakpoint 2, compdir_missing__ldir_missing__file_basename () at tmp-dw2-dir-file-name.c:999^M
-(gdb) FAIL: gdb.dwarf2/dw2-dir-file-name.exp: compdir_missing__ldir_missing__file_basename: continue to breakpoint: compdir_missing__ldir_missing__file_basename
+Breakpoint 2, 0x000085d4 in compdir_missing__ldir_missing__file_basename () at tmp-dw2-dir-file-name.c:999^M
+(gdb) PASS: gdb.dwarf2/dw2-dir-file-name.exp: compdir_missing__ldir_missing__file_basename: continue to breakpoint: compdir_missing__ldir_missing__file_basename
This difference is caused by setting breakpoint at the first instruction
in the function (actually, the first instruction in prologue, at [1]),
so that frame_show_address returns false, and print_frame doesn't print the
address.
0x00008620 <+0>: push {r11} ; (str r11, [sp, #-4]!) <--[1]
0x00008624 <+4>: add r11, sp, #0
0x00008628 <+8>: ldr r3, [pc, #24] ; 0x8648 <compdir_missing__ldir_missing__file_basename+40>
0x0000862c <+12>: ldr r3, [r3]
0x00008630 <+16>: add r3, r3, #1
0x00008634 <+20>: ldr r2, [pc, #12] ; 0x8648 <compdir_missing__ldir_missing__file_basename+40>
Then, it must be the arm_skip_prologue's fault that unable to skip
instructions in prologue. At the end of arm_skip_prologue, it matches
several instructions, such as "str r(0123),[r11,#-nn]" and
"str r(0123),[sp,#nn]", but "push {r11}" isn't handled.
These instruction matching code in arm_skip_prologue, which can be regarded
as leftover of development for many years, should be merged to
arm_analyze_prologue and use arm_analyze_prologue in arm_skip_prologue.
Here is the something like the history of arm_{skip,scan,analyze}_prologue.
Around 2002, there are arm_skip_prologue and arm_scan_prologue, but code are
duplicated to some extent. When match an instruction, both functions should
be modified, for example in Michael Snyder's patch
https://sourceware.org/ml/gdb-patches/2002-05/msg00205.html and Michael
expressed the willingness to merge both into one. Daniel added code call
thumb_analyze_prologue in arm_skip_prologue in 2006, but didn't handle its
counterpart arm_analyze_prologue, which is added in 2010
<https://sourceware.org/ml/gdb-patches/2010-03/msg00820.html>
however, the instructions matching at the bottom of arm_skip_prologue wasn't
cleaned up. This patch is to merge them into arm_analyze_prologue.

Only leave dprintf inserted if it is marked as persistent (PR breakpoints/17012)
On Linux native, if dprintfs are inserted when detaching, they are left
in the inferior which causes it to crash from a SIGTRAP. It also happens
with dprintfs on remote targets, when set disconnected-dprintf is off.
The rationale of the line modified by the patch was to leave dprintfs
inserted in order to support disconnected dprintfs. However, not all
dprintfs are persistent. Also, there's no reason other kinds of
breakpoints can't be persistent either. So this replaces the bp_dprintf
check with a check on whether the location is persistent.
bl->target_info.persist will be 1 only if disconnected-dprintf is on and
we are debugging a remote target. On native, it will always be 0,
regardless of the value of disconnected-dprintf. This makes sense, since
disconnected dprintfs are not supported by the native target.
One issue about the test is that it does not pass when using
--target_board=native-extended-gdbserver, partly due to bug 17302 [1].
One quick hack I tried for this was to add a useless "next" between the
call to getpid() and detach, which avoids the bug. There is still one
case where the test fails, and that is with:
- breakpoint always-inserted on
- dprintf-style agent
- disconnected-dprintf on
What happens is that my detach does not actually detach the process,
because some persistent commands (the disconnected dprintf) is present.
However since gdbserver is ran with --once, when gdb disconnects,
gdbserver goes down and takes with it all the processes it spawned and
that are still under its control (which includes my test process).
When the test checks if the test process is still alive, it obvisouly
fails. Investigating about that led me to ask a question on the ML [2]
about the behavior of detach.
Until the remote case is sorted out, the problematic test is marked as
KFAIL.

Restore terminal state in mi_thread_exit (PR gdb/17627)
When a thread exits, the terminal is left in mode "terminal_is_ours"
while the target executes. This patch fixes that.
We need to manually restore the terminal setting in this particular
observer. In the case of the other MI observers that call
target_terminal_ours, gdb will end up resuming the inferior later in the
execution and call target_terminal_inferior. In the case of the thread
exit event, we still need to call target_terminal_ours to be able to
print something, but there is nothing that gdb will need to resume after
that. We therefore need to call target_terminal_inferior ourselves.

Don't return DW_AT_name for function name in C++
DW_AT_name for functions typically just contains the base function
name, so lacks namespace, class and parameter information. It would
be possible to extract all these from the DWARF, but at a considerable
complication of the parser in dwarf2.c, and then you'd need to mangle
it all together. Much simpler is to look up the actual symbol. This
patch does that, avoiding the extra symbol lookup when the language
doesn't do name mangling.

Unify lookup_symbol_in_objfile_symtabs
That's right, block_lookup_symbol_primary()'s additional requirement over
block_lookup_symbol() is:
Function is useful if one iterates all global/static blocks of an
objfile.
Which is satisfied both in lookup_symbol_in_objfile_symtabs() and in
lookup_global_symbol_from_objfile() thanks to their's ALL_OBJFILE_COMPUNITS.
In fact after reverting that ba715d7fe49c8a59660fbd571b935b29eb7cfbdb above
the lines of code were exactly the same.
So instead of accelerating both lookup_symbol_in_objfile_symtabs() and
lookup_global_symbol_from_objfile() I just accelerated
lookup_symbol_in_objfile_symtabs() and I am proposing to reuse
lookup_symbol_in_objfile_symtabs() in lookup_global_symbol_from_objfile()
instead. In fact such unification would already save some lines of code even
before the checked-in acceleration patch above.

This patch is to remove the third argument of gdb_remote_download, so
that gdb_remote_download can return the correct location.
Further, these tests only copy .scm files to a different name. From what
I can tell from the comments, looks we do this to avoid clobbering file
in in-tree build. However, if source and dest of copy are the same, the
operation is no-op. So it makes few sense to copy .scm files to a
different names. I tried in-tree build/test with this patch, test
result isn't changed.

Revert: linespec.c (iterate_name_matcher): Fix arguments to symbol_name_cmp.
This patch causes regressions in ada's operator_bp.exp test.
That's because it uses wild_match which expects arguments in
the original order.
There is still a bug here. It's hard to see because either minsyms
save the day, or the needed symtab gets expanded before linespecs
need it because of the call to cp_canonicalize_string_no_typedefs
in linespec.c:find_linespec_symbols.
But if you disable both of those things, then the bug is visible.

the function pointer to get the PLT entry symbol value array indexed
by relocation index, instead of calling plt_sym_val on each relocation
index.

Accelerate lookup_symbol_aux_objfile 85x
During debugging I get 10-30 seconds for a response to simple commands like:
(gdb) print vectorvar.size()
With this patch the performance gets to 1-2 seconds which is somehow
acceptable. The problem is that dwarf2_gdb_index_functions.lookup_symbol
(quick_symbol_functions::lookup_symbol) may return (and returns) NULL even for
symbols which are present in .gdb_index but which can be found in already
expanded symtab. But searching in the already expanded symtabs is just too
slow when there are 400000+ expanded symtabs. There would be needed some
single global hash table for each objfile so that one does not have to iterate
all symtabs. Which .gdb_index could perfectly serve for, just its
lookup_symbol() would need to return authoritative yes/no answers.
Even after such fix these two simple patches are useful for example for
non-.gdb_index files.
One can reproduce the slugging interactive GDB performance with:
#include <string>
using namespace std;
string var;
class C {
public:
void m() {}
};
int main() {
C c;
c.m();
return 0;
}
g++ -o slow slow.C -Wall -g $(pkg-config --libs gtkmm-3.0)
gdb ./slow -ex 'b C::m' -ex 'maintenance set per-command space' -ex 'maintenance set per-command symtab' -ex 'maintenance set per-command

Without DWZ there are X global blocks for X primary symtabs for X CUs of
objfile. With DWZ there are X+Y global blocks for X+Y primary symtabs for
X+Y CUs where Y are 'DW_TAG_partial_unit's.
For 'DW_TAG_partial_unit's (Ys) their blockvector is usually empty. But not
always, I have found there typedef symbols, there can IMO be optimized-out
static variables etc.
Neither of the patches should cause any visible behavior change.

Correct invalid assumptions made by (mostly) DWARF-2 tests
Address issues triggered by the MIPS ISA bit handling change, usually in
tests that make artificial DWARF-2 records:
* gdb.cp/expand-psymtabs-cxx.exp -- this test is debugging an object file
and assuming addresses will be 0; with the ISA bit set code addresses
are 1 instead:
(gdb) PASS: gdb.cp/expand-psymtabs-cxx.exp: set language c++
p 'method(long)'
$1 = {void (long)} 0x1 <method(long)>
(gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: before expand
p method
$2 = {void (long)} 0x1 <method(long)>
(gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: force expand
p 'method(long)'
$3 = {void (long)} 0x1 <method(long)>
(gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: after expand
Fix by matching any hex number, there's no value AFAICT for the test
in matching 0 exactly, and I suppose the method's offset within
section can be non-zero for some other reasons on other targets too.
* gdb.cp/nsalias.exp -- this assumes instructions can be aligned
arbitrarily and places code labels at odd addreses, setting the ISA
bit and wreaking havoc:
(gdb) PASS: gdb.cp/nsalias.exp: print outer::inner::innermost::x
list outer::inner::innermost::foo
Function "outer::inner::innermost::foo" not defined.
(gdb) FAIL: gdb.cp/nsalias.exp: list outer::inner::innermost::foo
break *outer::inner::innermost::foo
No symbol "foo" in namespace "outer::inner::innermost".
(gdb) FAIL: gdb.cp/nsalias.exp: setting breakpoint at
*outer::inner::innermost::foo
delete $bpnum
No breakpoint number 6.
(gdb) FAIL: gdb.cp/nsalias.exp: (outer::inner::innermost): delete $bpnum
-- etc., etc... Fix by aligning labels to 4; required by many
processors.
* gdb.dwarf2/dw2-canonicalize-type.exp, gdb.dwarf2/dw2-empty-pc-range.exp,
gdb.dwarf2/pr11465.exp -- these assume an instruction and consequently
a function can take as little as 1 byte, which makes it impossible to
look up a code symbol by an address with the ISA bit set as the
address is already beyond the end of the function:
(gdb) ptype f
No symbol "f" in current context.
(gdb) FAIL: gdb.dwarf2/dw2-canonicalize-type.exp: ptype f
(gdb) PASS: gdb.dwarf2/dw2-empty-pc-range.exp: empty range before CU load
ptype realrange
No symbol "realrange" in current context.
(gdb) FAIL: gdb.dwarf2/dw2-empty-pc-range.exp: valid range after CU load
(gdb) p N::c.C
Cannot take address of method C.
(gdb) FAIL: gdb.dwarf2/pr11465.exp: p N::c.C
-- fix by increasing the size of the function to 4 (perhaps code in
gdb/mips-tdep.c could look up code symbols up to twice, with and
failing that without the ISA bit set, but it seems wrong to me to
implement specific handling for invalid code just to satisfy test
cases that assume too much about the target).
* gdb.dwarf2/dw2-case-insensitive.exp -- an artificial code label is
created, but does not work because data (a `.align' pseudo-op in this
case) follows and as a result the label has no MIPS16 or microMIPS
annotation in the symbol table:
(gdb) PASS: gdb.dwarf2/dw2-case-insensitive.exp: set case-sensitive off
info functions fUnC_lang
All functions matching regular expression "fUnC_lang":

(gdb) FAIL: gdb.dwarf2/dw2-case-insensitive.exp: regexp case-sensitive off
-- fix by adding a `.insn' pseudo-op on MIPS targets; the pseudo-op
marks data as instructions.

and assumes none will be issued beyond ones explicitly arranged by the
test case, however overlapping sections are noticed while minimal
symbols are looked up by `mips_adjust_dwarf2_addr' in DWARF-2 record

powerpc gold, work around pr17670
pr17670 is about an assert triggering on a branch to an undefined
weak symbol, the symbol being undefined due to dropping its comdat
group section. (Well sort of. The symbol is actually defined in
an .opd section which isn't part of the group, but the code section
the opd entry points at is dropped.) So don't assert.
Also, don't make long branch stubs to such symbols, and arrange to
have target-reloc.h code warn when applying relocs that use the sym.

MIPS: Add support for microMIPS Linux signal trampolines
The necessity for this change has been revealed in the course of
investigation related to proposed changes in the treatment of the ISA
bit encoded in function symbols on the MIPS target. This change adds
support for Linux signal trampolines encoded with the microMIPS
instruction set. Such trampolines are used by the Linux kernel if
compiled as a microMIPS binary (even if the binary run/debugged itself
contains no microMIPS code at all).
To see if we need to check whether the execution mode selected matches
the given trampoline I have checked what the bit patterns of all the
trampoline sequences decode to in the opposite instruction set. This
produced useless or at least unusual code in most cases, for example:
microMIPS/EB, o32 sigreturn, decoded as MIPS code:
30401017 andi zero,v0,0x1017
00008b7c dsll32 s1,zero,0xd
MIPS/EL, o32 sigreturn, decoded as microMIPS code:
1017 2402 addi zero,s7,9218
000c 0000 sll zero,t0,0x0
However in some corner cases reasonable code can mimic a trampoline, for
example:
MIPS/EB, n32 rt_sigreturn, decoded as microMIPS code:
2402 sll s0,s0,1
1843 0000 sb v0,0(v1)
000c 0f3c jr t0
-- here the first instruction is a 16-bit one, making things nastier
even as there are some other microMIPS instructions whose first 16-bit
halfword is 0x000c and therefore matches this whole trampoline pattern.
To overcome this problem I have decided the signal trampoline unwinder
has to ask the platform backend whether it can apply a given trampoline
pattern to the code location being concerned or not. Anticipating the
acceptance of the ISA bit proposal I decided the handler not to merely
be a predicate, but also to be able to provide an adjusted PC if
required. I decided that returning zero will mean that the trampoline
pattern is not applicable and any other value is the adjusted PC to use;
a handler may return the value requested if the trampoline pattern and
the PC requested as-is are both accepted.
This changes the semantics of the trampoline unwinder a bit in that the
zero PC now has a special value. I think this should be safe as a NULL
pointer is generally supposed to be invalid.

So, the following fields in struct host_callback_struct...
int (*stat) (host_callback *, const char *, struct stat *);
int (*fstat) (host_callback *, int, struct stat *);
int (*lstat) (host_callback *, const char *, struct stat *);
... get translated to...
int (*_stati64) (host_callback *, const char *, struct _stati64 *);
int (*_fstati64) (host_callback *, int, struct _stati64 *);
int (*_stati64) (host_callback *, const char *, struct _stati64 *);
... which causes two fields to have the same name.
This patch fixes the issue by renaming the stat-related fields
by adding a "to_" prefix, similar to what is done in GDB's
target_ops vector.

Remove cplus_specific from general_symbol_info.
This patch reverts the addition of cplus_specific added here:
2010-07-16 Sami Wagiaalla <swagiaal@redhat.com>
* symtab.h (symbol_set_demangled_name): Now takes an optional objfile*
argument.
(cplus_specific): New struct.
* symtab.c (symbol_set_demangled_name): Updated.
Use cplus_specific for cplus symbols.
(symbol_get_demangled_name): Retrive the name from the cplus_specific

(symbol_init_language_specific): Set cplus_specific for cplus symbols.
(symbol_set_names): Pass objfile to symbol_set_demangled_name.
* symtab.c (symbol_init_cplus_specific): New function.
It was added in anticipation of improved template support:
https://sourceware.org/ml/gdb-patches/2010-05/msg00594.html
https://sourceware.org/ml/gdb-patches/2010-07/msg00284.html
However, minsyms pay the price for this space too.
For my standard benchmark this patch gets back 44MB of memory
when gdb starts. [There's still ~440MB of memory used
by the demangled ELF symbols of this benchmark, but that's another topic.]
When the improved templated support is added,
I wonder if this can be moved to struct symbol.
Hmmm, we already have a special version of
struct symbol for templates (struct template_symbol).
gdb/ChangeLog:
* symtab.c (symbol_init_cplus_specific): Delete.

(symbol_get_demangled_name, symbol_set_language): Ditto.

execl-update-breakpoints.exp: Move whole segment instead of .text section
The test case builds two copies of the program, one with the compile
option "ldflags=-Wl,-Ttext=0x1000000" and the other with the address
changed to 0x2000000. However, when linking with ld.bfd, the
resulting executables crash early in ld.so on S390 and i386.
Analysis of the crash: The default linker script establishes a certain
order of loadable sections, and the option "-Ttext" effectively splits
these into an "unaffected" lot (everything before .text) and an
"affected" lot. The affected lot is placed at the given address,
whereas the unaffected lot stays at its default address. The
unaffected lot starts at an aligned address plus Elf header sizes,
which is good if it is the first LOAD segment (like on AMD64). But if
the affected lot comes first instead (like on S390 and i386), the PHDR
doesn't fit there and is placed *outside* any LOAD segments. Then the
PHDR is not mapped when the loader gets control, and the loader runs
into a segmentation fault while trying to access it.
Since we are lucky about the order of segments on AMD64, the test
succeeds there, but the resulting binaries are unusually large -- 2.1M
each, with lots of padding within.
When replacing '-Ttext' by '-Ttext-segment', the linker moves all
segments consistently, the binaries have normal sizes, and the test
case succeeds on all mentioned platforms.
Since old versions of the gold linker don't support '-Ttext-segment',
the patch also adds logic for falling back to '-Ttext'.
gdb/testsuite/ChangeLog:
* gdb.base/execl-update-breakpoints.exp: Specify the link address
with '-Ttext-segment' instead of '-Ttext'. Fall back to '-Ttext'
if the linker doesn't understand this.

Fix extraneous warning about executable stack.
PR gold/17578 notes that gold will print a warning about an executable stack
when the -z execstack option is given, even when there is no --warn_execstack
option. The warning is completely useless and unexpected, since the user
explicitly requested an executable stack, and did not even ask for warnings.
This patch fixes that, and adds an extra warning when --warn_execstack

stack.

Add add-auto-load-scripts-directory.
There is already "add-auto-load-safe-path" which works
like "set auto-load safe-path" but in append mode.
There was missing an append equivalent for "set auto-load scripts-directory".
ABRT has directory /var/cache/abrt-di/ as an alternative one
to /usr/lib/debug/ . Therefore ABRT needs to use -iex parameters to add this
/var/cache/abrt-di/ directory as a first-class debuginfo directory.
Using absolute "set auto-load scripts-directory" would hard-code the path
possibly overriding local system directory additions; besides it would not be
nice anyway.

Correct fabs and fneg insns in simulator
It seems that the implementation of the SH fabs and fneg insns in the
simulator is not correct. They use the FP_UNARY macro which checks the
FPSCR.PR setting and raises an exception if PR = 1 (double precision)
and the register number is not even (i.e. a valid DF reg number).
For normal unary FP insns this is fine. However, fneg and fabs perform
the same (integer) operations regardless of the FPSCR.PR setting.
This issue initially popped up here
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63260
I've checked some of the failing tests mentioned in GCC PR 63260 above
with the patch applied and the failures go away.
sim/sh/ChangeLog (tiny patch):
* gencode.c (fabs, fneg): Implement as integer operation
instead of using the FP_UNARY macro.

Remove (dead-code) native core file sniffers on Linux targets
Since Andreas Arnez' recent patch series, all Linux targets install
gdbarch_iterate_over_regset_sections routines. This means that on
Linux native targets, old-style core sniffers are never used.
Most Linux targets haven't been using such sniffers for a long time
anyway, but a couple remain: ia64 and sparc use core-regset.o, and
m68k installs its own core_fns. All this is now dead code, which
this commit removes.

Match library name prefixed with sysroot
We enable systemtap probe in glibc recently, and see the following gdb fail,
(gdb) set solib-absolute-prefix /.
...
Stopped due to shared library event:^M
Inferior loaded /./foo/bar/gdb.base/break-probes-solib.so
...
(gdb) FAIL: gdb.base/break-probes.exp: run til our library loads (the program exited)
$binfile_lib is /foo/bar/gdb.base/break-probes-solib.so, but the
sysroot is prefixed in solib.c:solib_find, as comments described:
Global variable GDB_SYSROOT is used as a prefix directory
to search for shared libraries if they have an absolute path.
so the output becomes "/./foo/bar/gdb.base/break-probes-solib.so", which
is still correct. However, the test repeatedly continue the program
and tries to match $binfile_lib, finally, the program exits and the
test fails.
This patch is to adjust the pattern to match $sysroot$binfile_lib
instead of $binfile_lib.

Fix test always passing in python/py-linetable.exp
The following test is found in python/py-linetable.exp:
gdb_test "python print sorted(fset)" \
"\[20L, 21L, 22L, 24L, 25L, 28L, 29L, 30L, 32L, 33L, 37L, 39L, 40L, 42L, 44L, 45L, 46L\].*" \
"Test frozen set contains line numbers"
I noticed that it passed when using Python 3, even though it should fail
because of the missing parentheses for the call print.
There needs to be more escaping of the square brackets. Currently, it is
interpreted as "any one character from this big list of characters,
followed by .*". When adding the required amount of backslashes, the
test starts failing as it should.
Moreover, both in Python 2.7 and Python 3.3 the numbers don't have the L
suffix, so now the test fails because of that. Anybody knows why they
were there in the first place? I just tested with Python 2.4 and there
are no Ls.
gdb/testsuite/ChangeLog:
* gdb.python/py-linetable.exp: Escape properly sorted(fset)
test expected output. Add parentheses for the call to print.
Remove L suffix from integers.

_bfd_elf_slurp_version_tables tidy
The internal verref buffer is allocated with bfd_zalloc, based on a
count given in headers. If the headers are broken/fuzzed and contain
an enormous count the alloc can result in OOM. If we first read the

the read provides a sanity check on the headers.
Also prints an error for version info that fails other sanity checks.

Optimize out i386/x86-64 JUMP_SLOT relocation
When there are both PLT and GOT references to the same function symbol,
linker will create a GOTPLT slot for PLT entry and a GOT slot for GOT
reference. A run-time JUMP_SLOT relocation is created to update the
GOTPLT slot and a run-time GLOB_DAT relocation is created to update the
GOT slot. Both JUMP_SLOT and GLOB_DAT relocations will apply the same
symbol value to GOTPLT and GOT slots, respectively, at run-time.
This optimization combines GOTPLT and GOT slots into a single GOT slot
and removes the run-time JUMP_SLOT relocation. It replaces the regular
PLT entry:
indirect jump [GOTPLT slot]
push relocation index
jump PLT0
with an GOT PLT entry with an indirect jump via the GOT slot:
indirect jump [GOT slot]
nop
and resolves PLT reference to the GOT PLT entry.
We must avoid this optimization if pointer equality is needed since
we don't clear symbol value in this case and the dynamic linker won't
update the GOT slot. Otherwise, the resulting binary will get into an
infinite loop at run-time.

Always consider infcall breakpoints as non-permanent.
A recent change...
commit 1a853c5224e2b8fedfac6d029365522b83080b40
Date: Wed Nov 12 10:10:49 2014 +0000
Subject: make "permanent breakpoints" per location and disableable
... broke function calls on sparc-elf when running over QEMU. Any
function call should demonstrate the problem.
For instance, seen from the debugger:
(gdb) call pn(1234)
[Inferior 1 (Remote target) exited normally]
The program being debugged exited while in a function called from GDB.
Evaluation of the expression containing the function
And seen from QEMU:
qemu: fatal: Trap 0x02 while interrupts disabled, Error state
[register dump removed]
What happens in this case is that GDB sets the inferior function call
by not only creating the dummy frame, but also writing a breakpoint
instruction at the return address for our function call. See infcall.c:
/* Write a legitimate instruction at the point where the infcall
breakpoint is going to be inserted. While this instruction
is never going to be executed, a user investigating the
memory from GDB would see this instruction instead of random
uninitialized bytes. We chose the breakpoint instruction
as it may look as the most logical one to the user and also
valgrind 3.7.0 needs it for proper vgdb inferior calls.
If software breakpoints are unsupported for this target we
leave the user visible memory content uninitialized. */
bp_addr_as_address = bp_addr;
bp_bytes = gdbarch_breakpoint_from_pc (gdbarch, &bp_addr_as_address,
&bp_size);
if (bp_bytes != NULL)
write_memory (bp_addr_as_address, bp_bytes, bp_size);
This instruction triggers a change introduced by the commit above,
where we consider bp locations as being permanent breakpoints
if there is already a breakpoint instruction at that address:
+ if (bp_loc_is_permanent (loc))
+ {
+ loc->inserted = 1;
+ loc->permanent = 1;
+ }
As a result, when resuming the program's execution for the inferior
function call, GDB decides that it does not need to insert a breakpoint
at this address, expecting the target to just report a SIGTRAP when
trying to execute that instruction.
But unfortunately for us, at least some versions of QEMU for SPARC
just terminate the execution entirely instead of reporting a breakpoint,
thus producing the behavior reported here.
Although it appears like QEMU might be misbehaving and should therefore
be fixed (to be verified) from the user's point of view, the recent
change does introduce a regression. So this patch tries to mitigate
a bit the damage by handling such infcall breakpoints as special and
making sure that they are never considered permanent, thus restoring
the previous behavior specifically for those breakpoints.
The option of not writing the breakpoint instructions in the first
place was considered, and would probably work also. But the comment
associated to it seems to indicate that there is still reason to
keep it.
gdb/ChangeLog:
* breakpoint.c (bp_loc_is_permanent): Return 0 if LOC corresponds
to a bp_call_dummy breakpoint type.
Tested on x86_64-linux. Also testing on sparc-elf/QEMU using
AdaCore's testsuite.

Specify SA_RESTART when registering the SIGWINCH signal handler
SA_RESTART allows system calls to be restarted across a signal handler.
By specifying this flag we fix the issue where if the user is being
prompted to answer yes or no, and the terminal gets resized in the
meantime, the prompt will think that the user sent an EOF and so it will
take the default action for that prompt (in the case of the quit prompt,
it will quit GDB).

* tui/tui-win.c (tui_initialize_win): Specify SA_RESTART when

Fix the processing of Meta-key commands in TUI
This patch fixes the annoying bug where key sequences such as Alt_F or
Alt_B (go forward or backwards by a word) do not behave promptly in TUI.
You have to press a third key in order for the key sequence to register.
This is mostly ncurses' fault. Calling wgetch() normally causes ncurses
to read only a single key from stdin. However if the key read is the
start-sequence key (^[ a.k.a. ESC) then wgetch() reads TWO keys from
stdin, storing the 2nd key into an internal FIFO buffer and returning
the start-sequence key. The extraneous read of the 2nd key makes us
miss its corresponding stdin event, so the event loop blocks until a
third key is pressed. This explains why such key sequences do not
behave promptly in TUI.
To fix this issue, we must somehow compensate for the missed stdin event
corresponding to the 2nd byte of a key sequence. This patch achieves
this by hacking up the stdin event handler to conditionally execute the
readline callback multiple times in a row. This is done via a new
global variable, call_stdin_event_handler_again_p, which is set from
tui_getc() when we receive a start-sequence key and notice extra pending
input in the ncurses buffer.
Tested on x86_64-unknown-linux-gnu.
gdb/ChangeLog:
* event-top.h (call_stdin_event_handler_again_p): Declare.
* event-top.c (call_stdin_event_handler_again_p): Define.
(stdin_event_handler): Use it.
* tui/tui-io.c (tui_getc): Prepare to call the stdin event
handler again if there is pending input following a
start sequence.

Refine read_string
In read_string, we have this line
chunksize = (len == -1 ? min (8, fetchlimit) : fetchlimit);
but chunksize is only used in the block that lne == -1, so IWBN to
move chunksize to the block in which it is used, and simplify the
condition setting chunksize. This patch also moves 'found_nul' to
inner block. This patch also splits a paragraph of comment into two,
and move them to different condition blocks (len > 0 and len == -1)
respectively.

commit 45e44d277a1b558bb77ea0a1962172a06be26594
Author: Joel Brobecker <brobecker@adacore.com>
Date: Thu Oct 2 15:17:49 2014 -0700
Handling of empty Ada ranges with a negative upper bound.
Consider the following variable declaration:
type Array_Type is array (Integer range <>) of Integer;
Var: Array_Type (0 .. -1);
"ptype var" prints the wrong upper bound for that array:
(gdb) ptype var
type = array (0 .. 4294967295) of integer
The debugging info for the type of variable "Var" is as follow:
<2><cf>: Abbrev Number: 13 (DW_TAG_structure_type)
<d0> DW_AT_name : foo__var___PAD
<3><db>: Abbrev Number: 14 (DW_TAG_member)
<dc> DW_AT_name : F
<e0> DW_AT_type : <0xa5>
This is just an artifact from code generation, which is just
a wrapper that we should ignore. The real type is the type of
field "F" in that PAD type, which is described as:
<2><a5>: Abbrev Number: 10 (DW_TAG_array_type)
<a6> DW_AT_name : foo__TvarS
<3><b6>: Abbrev Number: 11 (DW_TAG_subrange_type)
<b7> DW_AT_type : <0xc1>
<bb> DW_AT_lower_bound : 0
<bc> DW_AT_upper_bound : 0xffffffff
Trouble occurs because DW_AT_upper_bound is encoded using
a DW_FORM_data4, which is ambiguous regarding signedness.
In that case, dwarf2read.c::dwarf2_get_attr_constant_value
reads the value as unsigned, which is not what we want
in this case.
As it happens, we already have code dealing with this situation
in dwarf2read.c::read_subrange_type which checks whether
the subrange's type is signed or not, and if it is, fixes
the bound's value by sign-extending it:
if (high.kind == PROP_CONST
&& !TYPE_UNSIGNED (base_type) && (high.data.const_val & negative_mask))
high.data.const_val |= negative_mask;
Unfortunately, what happens in our case is that the base type
of the array's subrange type is marked as being unsigned, and
so we never get to apply the sign extension. Following the DWARF
trail, the range's base type is described as another subrange type...
<2><c1>: Abbrev Number: 12 (DW_TAG_subrange_type)
<c7> DW_AT_name : foo__TTvarSP1___XDLU_0__1m
<cb> DW_AT_type : <0x2d>
... whose base type is, (finally), a basic type (signed):
<1><2d>: Abbrev Number: 2 (DW_TAG_base_type)
<2e> DW_AT_byte_size : 4
<2f> DW_AT_encoding : 5 (signed)
<30> DW_AT_name : integer
The reason why GDB thinks that foo__TTvarSP1___XDLU_0__1m
(the base type of the array's range type) is an unsigned type
is found in gdbtypes.c::create_range_type. We consider that
a range type is unsigned iff its lower bound is >= 0:
if (low_bound->kind == PROP_CONST && low_bound->data.const_val >= 0)
TYPE_UNSIGNED (result_type) = 1;
That is normally sufficient, as one would expect the upper bound to
always be greater or equal to the lower bound. But Ada actually
allows the declaration of empty range types where the upper bound
is less than the lower bound. In this case, the upper bound is
negative, so we should not be marking the type as unsigned.
This patch fixes the issue by simply checking the upper bound as well
as the lower bound, and clears the range type's unsigned flag when
it is found to be constant and negative.
gdb/ChangeLog:
* gdbtypes.c (create_range_type): Unset RESULT_TYPE's
flag_unsigned if HIGH_BOUND is constant and negative.
gdb/testsuite/ChangeLog:
* gdb.ada/n_arr_bound: New testcase.

Partial fix for PR breakpoints/10737: Make syscall info be per-arch instead of global
This patch intends to partially fix PR breakpoints/10737, which is
about making the syscall information (for the "catch syscall" command)
be per-arch, instead of global. This is not a full fix because of the
other issues pointed by Pedro here:
<https://sourceware.org/bugzilla/show_bug.cgi?id=10737#c5>
However, I consider it a good step towards the real fix. It will also
help me fix <https://sourceware.org/bugzilla/show_bug.cgi?id=17402>.
What this patch does, basically, is move the "syscalls_info"
struct to gdbarch. Currently, the syscall information is stored in a
global variable inside gdb/xml-syscall.c, which means that there is no
easy way to correlate this info with the current target or
architecture being used, for example. This causes strange behaviors,
because the syscall info is not re-read when the arch changes. For
example, if you put a syscall catchpoint in syscall 5 on i386 (syscall
open), and then load a x86_64 program on GDB and put the same syscall
5 there (fstat on x86_64), you will still see that GDB tells you that
it is catching "open", even though it is not. With this patch, GDB
correctly says that it will be catching fstat syscalls.
(gdb) set architecture i386
The target architecture is assumed to be i386
(gdb) catch syscall 5
Catchpoint 1 (syscall 'open' [5])
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64
(gdb) catch syscall 5
Catchpoint 2 (syscall 'open' [5])
But with the patch:
(gdb) set architecture i386
The target architecture is assumed to be i386
(gdb) catch syscall 5
Catchpoint 1 (syscall 'open' [5])
(gdb) set architecture i386:x86-64
The target architecture is assumed to be i386:x86-64
(gdb) catch syscall 5
Catchpoint 2 (syscall 'fstat' [5])
As I said, there are still some problems on the "catch syscall"
mechanism, because (for example) the user should be able to "catch
syscall open" on i386, and then expect "open" to be caught also on
x86_64. Currently, it doesn't work. I intend to work on this later.

Split struct symtab into two: struct symtab and compunit_symtab.
Currently "symtabs" in gdb are stored as a single linked list of
struct symtab that contains both symbol symtabs (the blockvectors)
and file symtabs (the linetables).
This has led to confusion, bugs, and performance issues.
This patch is conceptually very simple: split struct symtab into
two pieces: one part containing things common across the entire
compilation unit, and one part containing things specific to each
source file.
Example.
For the case of a program built out of these files:
foo.c
foo1.h
foo2.h
bar.c
foo1.h
bar.h
Today we have a single list of struct symtabs:
objfile -> foo.c -> foo1.h -> foo2.h -> bar.c -> foo1.h -> bar.h -> NULL
where "->" means the "next" pointer in struct symtab.
With this patch, that turns into:
objfile -> foo.c(cu) -> bar.c(cu) -> NULL
| |
v v
foo.c bar.c
| |
v v
foo1.h foo1.h
| |
v v
foo2.h bar.h
| |
v v
NULL NULL
where "foo.c(cu)" and "bar.c(cu)" are struct compunit_symtab objects,
and the files foo.c, etc. are struct symtab objects.
So now, for example, when we want to iterate over all blockvectors
we can now just iterate over the compunit_symtab list.
Plus a lot of the data that was either unused or replicated for each
symtab in a compilation unit now lives in struct compunit_symtab.
E.g., the objfile pointer, the producer string, etc.
I thought of moving "language" out of struct symtab but there is
logic to try to compute the language based on previously seen files,
and I think that's best left as is for now.
With my standard monster benchmark with -readnow (which I can't actually
do, but based on my calculations), whereas today the list requires
77MB to store all the struct symtabs, it now only requires 37MB.
A modest space savings given the gigabytes needed for all the debug info,
etc. Still, it's nice. Plus, whereas today we create a copy of dirname
for each source file symtab in a compilation unit, we now only create one
for the compunit.
So this patch is basically just a data structure reorg,
I don't expect significant performance improvements from it.
Notes:
1) A followup patch can do a similar split for struct partial_symtab.
I have left that until after I get the changes I want in to
better utilize .gdb_index (it may affect how we do partial syms).
2) Another followup patch *could* rename struct symtab.
The term "symtab" is ambiguous and has been a source of confusion.
In this patch I'm leaving it alone, calling it the "historical" name
of "filetabs", which is what they are now: just the file-name + line-table.

[Ada] XA type is not redundant if the ranges' subtypes do not match
Jan noticed that gdb.ada/arrayidx.exp regressed after I applied
the following patch:
commit 8908fca5772fcff9f7766158ba2aa59f5a2b1f68
Author: Joel Brobecker <brobecker@adacore.com>
Date: Sat Sep 27 09:09:34 2014 -0700
Subject: [Ada] Ignore __XA types when redundant.
What happens is that we're trying to print the value of
r_two_three, which is defined as follow:
type Index is (One, Two, Three);
type RTable is array (Index range Two .. Three) of Integer;
R_Two_Three : RTable := (2, 3);
The expected output is:
(gdb) p r_two_three
$1 = (two => 2, 3)
But after the patch above was applied, with the program program
compiled using gcc-gnat-4.9.2-1.fc21.x86_64 (x86_64-linux),
the output becomes:
(gdb) p r_two_three
$1 = (2, 3)
(the name of the first bound is missing). The problem comes from
the fact that the compiler described the array's index type as
a plain base type, instead of as a subrange of the enumerated type.
More particularly, this is what gcc-gnat-4.9.2-1.fc21.x86_64
generated:
<3><7ce>: Abbrev Number: 9 (DW_TAG_array_type)
<7cf> DW_AT_name : (indirect string, offset: 0xc13): p__rtable
[...]
<7d7> DW_AT_GNAT_descriptive_type: <0x98a>
[...]
<4><7df>: Abbrev Number: 8 (DW_TAG_subrange_type)
<7e0> DW_AT_type : <0xa79>
where DIE 0xa79 is:
<1><a79>: Abbrev Number: 2 (DW_TAG_base_type)
<a7a> DW_AT_byte_size : 8
<a7b> DW_AT_encoding : 7 (unsigned)
<a7c> DW_AT_name : (indirect string, offset: 0xfc): sizetype
The actual array subrange type can be found in the array's
parallel XA type (the DW_AT_GNAT_descriptive_type).
The recent commit correctly found that that bounds taken from
the descriptive type are the same as bounds of our array's index
type. But it failed to notice that ignoring this descriptive
type would make us lose the actual array index type, making us
think that we're printing an array indexed by integers.
I hadn't seen that problem, because the compiler I used produced
debugging info where the array's index type is correctly described:
<3><79f>: Abbrev Number: 10 (DW_TAG_array_type)
<7a0> DW_AT_name : (indirect string, offset: 0xb3d): p__rtable
[...]
<4><7b0>: Abbrev Number: 8 (DW_TAG_subrange_type)
<7b1> DW_AT_type : <0x9b2>
<7b5> DW_AT_upper_bound : 2
... where DIE 0x9b2 leads us to ...
<3><9b2>: Abbrev Number: 9 (DW_TAG_subrange_type)
[...]
<9b8> DW_AT_type : <0x962>
<2><962>: Abbrev Number: 22 (DW_TAG_enumeration_type)
<963> DW_AT_name : (indirect string, offset: 0xb34): p__index
[...]
This patch fixes the issue by also making sure that the subtype
of the original range type does match the subtype found in the
descriptive type.

Default powerpc64 to --plt-thread-safe for Go
Go is multi-threaded, so use thread-safe plt stubs. __go_go doesn't
actually start threads, but is a convenient libgo function with a
reasonably unique name that is called by all Go executables. (Threads
are started by a static function of libgo, runtime_newosproc, called
by a whole lot of global functions, including runtime_starttheworld
and runtime_main.)

Use 2-byte instead of 4-byte NOP on S390 in 'bp-permanent' test case
The bp-permanent test case assumes that a NOP is exactly as long as a
software breakpoint. This is not the case for the S390 "nop"
instruction, which is 4 bytes long, while a software breakpoint is
just 2 bytes long. The "nopr" instruction has the right size and can
be used instead.
Without this patch the test case fails on S390 when trying to continue
after SIGTRAP on the permanent breakpoint:
...
Continuing.

[all following completions entries snipped, all expected]
I tracked down this suprising entry to a minimal symbol whose name
is ".refptr.pck_E". The problem occurs while trying to see if
this symbol matches "pck" when doing wild-matching as we are doing
here:
/* Second: Try wild matching... */
if (!match && wild_match_p)
{
/* Since we are doing wild matching, this means that TEXT
may represent an unqualified symbol name. We therefore must
also compare TEXT against the unqualified name of the symbol. */
sym_name = ada_unqualified_name (ada_decode (sym_name));
if (strncmp (sym_name, text, text_len) == 0)
match = 1;
}
What happens is that ada_decode correctly identifies the fact that
SYM_NAME (".refptr.pck_E") is not following any GNAT encoding, and
therefore returns that same name, but bracketed: "<.refptr.pck_E>".
This is the convention we use for telling GDB that the decoded name
is not a real Ada name - and therefore should not be encoded for
operations such as name matching, symbol lookups, etc. So far, so good.
Next is the call to ada_unqualified_name, which unfortunately does
not notice that the decoded name it is being given isn't a natural
symbol, and just blindly strips everything up to the last do, returning
"pck_E>". And of course, "pck_E>" matches "pck" now, and so we end
up accepting this symbol as a match.
This patch fixes the problem by making ada_unqualified_name a little
smarter by making sure that the given decoded symbol name does not
start with '<'.
gdb/ChangeLog:
* ada-lang.c (ada_unqualified_name): Return DECODED_NAME if
it starts with '<'.

[Ada] Ignore __XA types when redundant.
Consider the following code which declares a variable A2 which
is an array of arrays of integers.
type Array2_First is array (24 .. 26) of Integer;
type Array2_Second is array (1 .. 2) of Array2_First;
A1 : Array1_Second := ((10, 11, 12), (13, 14, 15));
Trying to print the type of that variable currently yields:
(gdb) ptype A2
type = array (1 .. 2, 24 .. 26) of integer
This is not correct, as this is the description of a two-dimension
array, which is different from an array of arrays. The expected
output is:
(gdb) ptype a2
type = array (1 .. 2) of foo_n926_029.array2_first
GDB's struct type currently handles multi-dimension arrays the same
way arrays of arrays, where each dimension is stored as a sub-array.
The ada-valprint module considers that consecutive array layers
are in fact multi-dimension arrays. For array of arrays, a typedef
layer is introduced between the two arrays, creating a break between
each array type.
In our situation, A2 is a described as a typedef of an array type...
.uleb128 0x8 # (DIE (0x125) DW_TAG_variable)
.ascii "a2\0" # DW_AT_name
.long 0xfc # DW_AT_type
.uleb128 0x4 # (DIE (0xfc) DW_TAG_typedef)
.long .LASF5 # DW_AT_name: "foo__array2_second"
.long 0x107 # DW_AT_type
.uleb128 0x5 # (DIE (0x107) DW_TAG_array_type)
.long .LASF5 # DW_AT_name: "foo__array2_second"
.long 0xb4 # DW_AT_type
.uleb128 0x6 # (DIE (0x114) DW_TAG_subrange_type)
.long 0x11b # DW_AT_type
.byte 0x2 # DW_AT_upper_bound
.byte 0 # end of children of DIE 0x107
... whose element type is, as expected, a typedef to the sub-array
type:
.uleb128 0x4 # (DIE (0xb4) DW_TAG_typedef)
.long .LASF4 # DW_AT_name: "foo__array2_first"
.long 0xbf # DW_AT_type
.uleb128 0x9 # (DIE (0xbf) DW_TAG_array_type)
.long .LASF4 # DW_AT_name: "foo__array2_first"
.long 0xd8 # DW_AT_GNAT_descriptive_type
.long 0x1c5 # DW_AT_type
.uleb128 0xa # (DIE (0xd0) DW_TAG_subrange_type)
.long 0xf0 # DW_AT_type
.byte 0x18 # DW_AT_lower_bound
.byte 0x1a # DW_AT_upper_bound
.byte 0 # end of children of DIE 0xbf
The reason why things fails is that, during expression evaluation,
GDB tries to "fix" A1's type. Because the sub-array has a parallel
(descriptive) type (DIE 0xd8), GDB thinks that our array's index
type must be dynamic and therefore needs to be fixed. This in turn
causes the sub-array to be "fixed", which itself results in the
typedef layer to be stripped.
However, looking closer at the parallel type, we see...
.uleb128 0xb # (DIE (0xd8) DW_TAG_structure_type)
.long .LASF8 # DW_AT_name: "foo__array2_first___XA"
[...]
.uleb128 0xc # (DIE (0xe4) DW_TAG_member)
.long .LASF10 # DW_AT_name: "foo__Tarray2_firstD1___XDLU_24__26"
... that all it tells us is that the array bounds are 24 and 26,
which is already correctly provided by the array's DW_TAG_subrange_type
bounds, meaning that this parallel type is just redundant.
Parallel types in general are slowly being removed in favor of
standard DWARF constructs. But in the meantime, this patch kills
two birds with one stone:
1. It recognizes this situation where the XA type is useless,
and saves an unnecessary range-type fixing;
2. It fixes the issue at hand because ignoring the XA type results
in no type fixing being required, which allows the typedef layer
to be preserved.

(ada_is_redundant_index_type_desc): New function.

varsize-limit error printing element of packed array...
... when that packed array is part of a discriminated record and
one of the bounds is a discriminant.
Consider the following code:
type FUNNY_CHAR_T is (NUL, ' ', '"', '#', [etc]);
type FUNNY_STR_T is array (POSITIVE range <>) of FUNNY_CHAR_T;
pragma PACK (FUNNY_STR_T);
type FUNNY_STRING_T (SIZE : NATURAL := 1) is
record
STR : FUNNY_STR_T (1 .. SIZE) := (others => '0');
LENGTH : NATURAL := 4;
end record;
TEST: FUNNY_STRING_T(100);
GDB is able to print the value of variable "test" and "test.str".
But not "test.str(1)":
(gdb) p test
$1 = (size => 100, str => (33 'A', nul <repeats 99 times>), length => 1)
(gdb) p test.str
$2 = (33 'A', nul <repeats 99 times>)
(gdb) p test.str(1)
object size is larger than varsize-limit
The problem occurs during the phase where we are trying to resolve
the expression subscript operation. On the one hand of the subscript
operator, we have the result of the evaluation of "test.str", which
is our packed array. We have the following code to handle packed
arrays in particular:
if (ada_is_constrained_packed_array_type
(desc_base_type (value_type (argvec[0]))))
argvec[0] = ada_coerce_to_simple_array (argvec[0]);
This eventually leads to a call to constrained_packed_array_type
to return the "simple array". This function relies on a parallel
___XA type, when available, to determine the bounds. In our case,
we find type...
failure__funny_string_t__T4b___XA"
... which has one field describing the bounds of our array as:
failure__funny_string_t__T3b___XDLU_1__size
The part that interests us is after the ___XD suffix or,
in other words: "LU_1__size". What this means in GNAT encoding
parlance is that the lower bound is 1, and that the upper bound
is the value of "size". "size" is our discriminant in this case.
Normally, we would access the record's discriminant in order to
get the upper bound's value, but we do not have that information,
here. We are in a mode where we are just trying to "fix" the type
without an actual value. This is what the call to to_fixed_range_type
is doing, and because the fix'ing fails, it ends up returning
the ___XDLU type unmodified as our index type.
This shouldn't be a problem, except that the later part of
constrained_packed_array_type then uses that index_type to
determine the array size, via a call to get_discrete_bounds.
The problem is that the upper bound of the ___XDLU type is
dynamic (in the DWARF sense) while get_discrete_bounds implicitly
assumes that the bounds are static, and therefore accesses
them using macros that assume the bounds values are constants:
case TYPE_CODE_RANGE:
*lowp = TYPE_LOW_BOUND (type);
*highp = TYPE_HIGH_BOUND (type);
This therefore returns a bogus value for the upper bound,
leading to an unexpectedly large size for our array, which
later triggers the varsize-limit guard we've seen above.
This patch avoids the problem by adding special handling
of dynamic range types. It also extends the documentation
of the constrained_packed_array_type function to document
what happens in this situation.
gdb/ChangeLog:
* ada-lang.c (constrained_packed_array_type): Set the length
of the return array as if both bounds where zero if that
returned array's index type is dynamic.

Split up end_symtab_from_static_block into two.
This patch is conceptually quite simple.
If you look at end_symtab_from_static_block you'll see
that the static_block == NULL case is completely different
than the non-NULL case.
There's a lot of complexity to handle the NULL case but it seems
entirely unnecessary. For example, whether blockvector is NULL
is decided at the start, before this for loop:
for (subfile = subfiles; subfile; subfile = nextsub)
Secondly, after the for loop, we test symtab for non-NULL here:
/* Set this for the main source file. */
if (symtab)
but symtab will only ever be non-NULL if blockvector was non-NULL.
And if blockvector was non_NULL so will symtab.
The other case to consider is these lines of code executed before
the for loop:
/* Read the line table if it has to be read separately.
This is only used by xcoffread.c. */
if (objfile->sf->sym_read_linetable != NULL)
objfile->sf->sym_read_linetable (objfile);
/* Handle the case where the debug info specifies a different path
for the main source file. It can cause us to lose track of its
line number information. */
watch_main_source_file_lossage ();
From my reading of the code, neither of these is useful
in the static_block == NULL case.
Thus we can make the code more readable by splitting these two cases up,
which is what this patch does.

* buildsym.c (main_subfile): New static global.

FAIL: gdb.reverse/sigall-precsave.exp: reload precord save file
They happen for two reasons.
- mingw32 does not define SIGTRAP, so upon recording a core file, the
signal information will be missing, which in turn causes GDB to not
display the stopping signal when it loads the same core file. An
earlier message warns about this:
"warning: Signal SIGTRAP does not exist on this system."
- The testcase is crafted in a way that expects a pattern of the
stopping signal message instead of a successful core file read message.
The following patch fixes this by changing the old pattern to a more
reasonable one, while still ignoring the fact that mingw32-based GDB
does not record a SIGTRAP in a core file because it does not define
it.

[gdbserver/lynx] spurious failure to write in inferior memory
We noticed the following error on ppc-lynx178, using just about
any program:
(gdb) tar remote mytarget:4444
Remote debugging using mytarget:4444
0x000100c8 in _start ()

!!!-> Cannot remove breakpoints because program is no longer writable.
!!!-> Further execution is probably impossible.
Breakpoint 1, try () at try.adb:11

And, of course, trying to continue yielded the expected outcome:
(gdb) c
Continuing.
warning: Error removing breakpoint 1
Cannot remove breakpoints because program is no longer writable.
Further execution is probably impossible.
It turns out that the problem is caused by an intentional test
against a variable with an undefined value. After GDB receives
notification of the inferior stopping, it tries to remove the
breakpoint by sending a memory-write packet ("X10844,4:9 ").
This leads us to lynx_write_memory, where it tries to split
the memory-write into chunks of 4 bytes. And, in order to handle
writes which are not aligned on word boundaries, we have the
following code:
if (skip > 0 || truncate > 0)
/* We need to read the memory at this address in order to preserve
the data that we are not overwriting. */
lynx_read_memory (addr, (unsigned char *) &buf, xfer_size);
if (errno)
return errno;
(the comment explains what the code is about).
Unfortunately, the not-so-glaring error that we've made here is
that we're checking ERRNO regardless of whether we've called
lynx_read_memory. In our case, because we are writing 4 bytes
aligned on a word boundary, we do not call lynx_read_memory and
therefore test an ERRNO with an undefined value.
gdb/gdbserver/ChangeLog:
* lynx-low.c (lynx_write_memory): Put lynx_read_memory and
corresponding ERRNO check in same block.

Is it the primary symtab (where we canonically think of
blockvectors as being stored) or is it for a specific file

common-defs.h: include <stdarg.h> before <stdio.h>
When trying to build gdbserver on ppc-lynx178, the compiler reports
while trying to compile gdbserver/ax.c that vsprintf is not declared.
Looking at my C99 reference manual (a draft), I see the following
synopsis:
#include <stdarg.h>
#include <stdio.h>
int vsprintf(char * restrict s, [etc]);
Looking at stdio.h on LynxOS-178, if found where vsprintf gets
declared:
#if defined(__varargs_h) || defined(__stdarg_h) \
|| defined(_VARARGS_H) || defined(_STDARG_H)
extern int vsprintf _AP((char *, const char *, va_list));
#endif
Digging further, I noticed that common-defs.h, which is included
via server.h, includes stdarg.h after including stdio, explaining
why vsprintf does not get declared in this case.
This patch fixes the problem by including stdarg.h before stdio.h.

* common/common-defs.h: Move <stdarg.h> #include ahead of
<stdio.h> #include.

handle 'iconv's that define EILSEQ to ENOENT
We're currently pulling gnulib's errno module as a dependency of some
other module. That provides an errno.h that defines EILSEQ to a
distinct value if the system's errno.h doesn't define it already.
However, GNU iconv does this:
/* Get errno declaration and values. */
#include <errno.h>
/* Some systems, like SunOS 4, don't have EILSEQ. Some systems, like BSD/OS,
have EILSEQ in a different header. On these systems, define EILSEQ
ourselves. */
#ifndef EILSEQ
#define EILSEQ @EILSEQ@
#endif
That's in:
http://git.savannah.gnu.org/cgit/libiconv.git/tree/include/iconv.h.in
The "different header" mentioned is wchar.h. This is handled in:
http://git.savannah.gnu.org/cgit/libiconv.git/tree/m4/eilseq.m4
which defines @EILSEQ@ to ENOENT if EILSEQ isn't found in either
errno.h or wchar.h.
So if iconv sets errno to EILSEQ on such system's, it's really setting
it to ENOENT. And when we check for EILSEQ, we're checking for
gnulib's value. The result is we won't detect the error correctly.
As we dropped support for both SunOS 4 or old BSD/OS, maybe we don't
need to care about the wchar.h issue anymore. Still, AFAICS, gnulib's
m4/errno_h.m4 doesn't know that EILSEQ may be defined in wchar.h, and
so on such systems, ISTM gnulib ends up defining an incompatible
EILSEQ itself, but I think that should be fixed on the gnulib side, by
making it extract the EILSEQ value out of the system's wchar.h, like
GNU iconv does.
So that leaves handling the case of gnulib making up a EILSEQ value,
which we take as meaning the system really doesn't really define it,
which will be the same systems GNU iconv sets errno to ENOENT instead
of EILSEQ.
Looking at glibc's iconv it seems that ENOENT is never used there.
It seems it's safe to always treat ENOENT the same as EILSEQ.
The current EILSEQ definition under PHONY_ICONV is obviously stale as
gnulib garantees there's always a EILSEQ defined.

Fix dw2-ifort-parameter.exp fail with clang
The patch <https://sourceware.org/ml/gdb-patches/2014-03/msg00202.html>
fixed dw2-ifort-parameter.exp on powerpc64 by adding some labels to
get the start and end address of function func. This should also fix the
fail on thumb mode, however, this style is quite specific to gcc, and
other compiler, such as clang, may not guarantee the order of global
asms and functions. The test fails with clang:
$ make check RUNTESTFLAGS='dw2-ifort-parameter.exp CC_FOR_TARGET=clang'
(gdb) p/x param^M
No symbol "param" in current context.^M
(gdb) FAIL: gdb.dwarf2/dw2-ifort-parameter.exp: p/x param
With this patch applied, dw2-ifort-parameter.exp still passes for gcc
on arm thumb mode and popwerpc64, and it also passes for clang on
x86_linux.

Fix implptr-optimized-out.exp fail
Hi,
I see the fail in gdb.dwarf2/implptr-optimized-out.exp in thumb mode
(gdb) p p->f^M
No symbol "p" in current context.^M
(gdb) FAIL: gdb.dwarf2/implptr-optimized-out.exp: p p->f
and the crash on powerpc64
(gdb) continue^M
Continuing.^M
^M
Program received signal SIGSEGV, Segmentation fault.^M
0x7d82100810000828 in ?? ()
The cause of both is that we incorrectly set attribute low_pc, since
main isn't resolved to function start address on these targets.
In this patch, we replace attributes name, low_pc and high_pc with
MACRO_AT_func. The fail on thumb mode is fixed, and crash on
powerpc64 is fixed too.

DW attribute macro MACRO_AT_func and MACRO_AT_range
This patch addes DW macro attributes MACRO_AT_func and MACRO_AT_range
in dwarf assembler, which emits "DW_AT_low_pc func_start addr" and
"DW_AT_high_pc func_end addr". func_start and func_end are computed
automatically by proc function_range.
These two attributes are pseudo attribute or macro attribute, which
means they are not standard dwarf attribute in dwarf spec. Then can
be substituted or expanded to standard attributes or macro attributes.
See details in the comments to them. Dwarf assembler is extended to
handle them.
Now the attributes name/low_pc/high_pc can be replaced with
MACRO_AT_func like this:
subprogram {
{name main}
{low_pc main_start addr}
{high_pc main_end addr}
}
becomes:
subprogram {
{MACRO_AT_func { main ${srcdir}/${subdir}/${srcfile} }}
}
users don't have to worry about the start and end of function main, and
they only need to add a label main_label in main.

Drop non-prototype C function header variants: 'list' test case
Remove old-style function header variants from list0.h and list1.c.
Fill the removed lines with comments or empty lines, such that the

require heavy adjustments to list.exp, where many line numbers are
hard-coded, as well as a fair amount of knowledge about the source
code in and around certain lines. Thus the dependency on the line
numbering can not be eliminated so easily, and it may not even be a
useful goal for a "list" test case. Another option might be to adjust
the literal line numbers in list.exp, but even that is not as
straightforward as it may seem, since the test case expects certain
source lines to be exactly n lines apart.

GDBserver: don't resume all threads if the Hc thread disapears
There's code in linux_wait_1 that resumes all threads if the Hc thread
disappears. It's the wrong thing to do, as GDB has told GDBserver to
resume only one thread, because e.g., the user has scheduler-locking
enabled, or because GDB was stepping the program over a breakpoint.
Resuming all threads behind GDB's back can't be good in either case.
The right thing to do is to detect that that the (only) resumed thread
is gone, and let GDB know about it. The Linux backend is already
doing that nowadays, since:

Author: Pedro Alves <palves@redhat.com>
AuthorDate: Thu Feb 27 14:30:08 2014 +0000
Teach GDBserver's Linux backend about no unwaited-for children (TARGET_WAITKIND_NO_RESUMED).
The backend detects that all resumed threads have disappeared, and
returns TARGET_WAITKIND_NO_RESUMED to the core of GDBserver, which
then reports an error to GDB.
There's no need to frob the passed in ptid to wait for the continue
thread either -- linux_wait_for_event only returns events for resumed
threads.
The badness (of resuming threads) can actually be observed in the
testsuite, if we force-disable vCont support in GDBserver -- before
the patch, gdb.threads/no-unwaited-for-left.exp hangs if we disable
vCont:
(gdb) continue
Continuing.
FAIL: gdb.threads/no-unwaited-for-left.exp: continue to breakpoint: break-here (timeout)
... more cascading timeouts ....
After the patch, gdb.threads/no-unwaited-for-left.exp behaves the same
with or without vCont support:
(gdb) continue

GDBserver: ctrl-c after leader has exited
The target->request_interrupt callback implements the handling for
ctrl-c. User types ctrl-c in GDB, GDB sends a \003 to the remote
target, and the remote targets stops the program with a SIGINT, just
like if the user typed ctrl-c in GDBserver's terminal.
The trouble is that using kill_lwp(signal_pid, SIGINT) sends the
SIGINT directly to the program's main thread. If that thread has
exited already, then that kill won't do anything.
Instead, send the SIGINT to the process group, just like GDB
does (see inf-ptrace.c:inf_ptrace_stop).
gdb.threads/leader-exit.exp is extended to cover the scenario. It
fails against GDBserver before the patch.
Tested on x86_64 Fedora 20, native and GDBserver.

fix skipping permanent breakpoints
The gdb.arch/i386-bp_permanent.exp test is currently failing an
assertion recently added:
(gdb) stepi
../../src/gdb/infrun.c:2237: internal-error: resume: Assertion `sig != GDB_SIGNAL_0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
FAIL: gdb.arch/i386-bp_permanent.exp: Single stepping past permanent breakpoint. (GDB internal error)
The assertion expects that the only reason we currently need to step a
breakpoint instruction is when we have a signal to deliver. But when
stepping a permanent breakpoint (with or without a signal) we also
reach this code.
The assertion is correct and the permanent breakpoints skipping code
is wrong.
Consider the case of the user doing "step/stepi" when stopped at a
permanent breakpoint. GDB's `resume' calls the
gdbarch_skip_permanent_breakpoint hook and then happily continues
stepping:
/* Normally, by the time we reach `resume', the breakpoints are either
removed or inserted, as appropriate. The exception is if we're sitting
at a permanent breakpoint; we need to step over it, but permanent
breakpoints can't be removed. So we have to test for it here. */
if (breakpoint_here_p (aspace, pc) == permanent_breakpoint_here)
{
gdbarch_skip_permanent_breakpoint (gdbarch, regcache);
}
But since gdbarch_skip_permanent_breakpoint already advanced the PC
manually, this ends up executing the instruction that is _after_ the
breakpoint instruction. The user-visible result is that a single-step
steps two instructions.
The gdb.arch/i386-bp_permanent.exp test is actually ensuring that
that's indeed how things work. It runs to an int3 instruction, does
"stepi", and checks that "leave" was executed with that "stepi". Like
this:
(gdb) b *0x0804848c
Breakpoint 2 at 0x804848c
(gdb) c
Continuing.

=> 0x0804848e <+6>: ret
0x0804848f <+7>: nop
End of assembler dump.
(gdb)
One would instead expect that a stepi at 0x0804848c stops at
0x0804848d, _before_ the "leave" is executed. This commit changes GDB
this way. Care is taken to make stepping into a signal handler when
the step starts at a permanent breakpoint instruction work correctly.
The patch adjusts gdb.arch/i386-bp_permanent.exp in this direction,
and also makes it work on x86_64 (currently it only works on i*86).
The patch also adds a new gdb.base/bp-permanent.exp test that
exercises many different code paths related to stepping permanent
breakpoints, including the stepping with signals cases. The test uses
"hack/trick" to make it work on all (or most) platforms -- it doesn't
really hard code a breakpoint instruction.

make "permanent breakpoints" per location and disableable
"permanent"-ness is currently a property of the breakpoint. But, it
should actually be an implementation detail of a _location_. Consider
this bit in infrun.c:
/* Normally, by the time we reach `resume', the breakpoints are either
removed or inserted, as appropriate. The exception is if we're sitting
at a permanent breakpoint; we need to step over it, but permanent
breakpoints can't be removed. So we have to test for it here. */
if (breakpoint_here_p (aspace, pc) == permanent_breakpoint_here)
{
if (gdbarch_skip_permanent_breakpoint_p (gdbarch))
gdbarch_skip_permanent_breakpoint (gdbarch, regcache);
else
error (_("\
The program is stopped at a permanent breakpoint, but GDB does not know\n\
how to step past a permanent breakpoint on this architecture. Try using\n\
a command like `return' or `jump' to continue execution."));
}
This will wrongly skip a non-breakpoint instruction if we have a
multiple location breakpoint where the whole breakpoint was set to
"permanent" because one of the locations happened to be permanent,
even if the one GDB is resuming from is not.
Related, because the permanent breakpoints are only marked as such in
init_breakpoint_sal, we currently miss marking momentary breakpoints
as permanent. A test added by a following patch trips on that.
Making permanent-ness be per-location, and marking locations as such
in add_location_to_breakpoint, the natural place to do this, fixes
this issue...
... and then exposes a latent issue with mark_breakpoints_out. It's
clearing the inserted flag of permanent breakpoints. This results in
assertions failing like this:
Breakpoint 1, main () at testsuite/gdb.base/callexit.c:32
32 return 0;
(gdb) call callexit()
[Inferior 1 (process 15849) exited normally]
gdb/breakpoint.c:12854: internal-error: allegedly permanent breakpoint is not actually inserted
A problem internal to GDB has been detected,
further debugging may prove unreliable.
The call dummy breakpoint, which is a momentary breakpoint, is set on
top of a manually inserted breakpoint instruction, and so is now
rightfully marked as a permanent breakpoint. See "Write a legitimate
instruction at the point where the infcall breakpoint is going to be
inserted." comment in infcall.c.
Re. make_breakpoint_permanent. That's only called by solib-pa64.c.
Permanent breakpoints were actually originally invented for HP-UX [1].
I believe that that call (the only one in the tree) is unnecessary
nowadays, given that nowadays the core breakpoints code analyzes the
instruction under the breakpoint to automatically detect whether it's
setting a breakpoint on top of a breakpoint instruction in the
program. I know close to nothing about HP-PA/HP-UX, though.
[1] https://sourceware.org/ml/gdb-patches/1999-q3/msg00245.html, and
https://sourceware.org/ml/gdb-patches/1999-q3/msg00242.html
In addition to the per-location issue, "permanent breakpoints" are
currently always displayed as enabled=='n':
(gdb) b main
Breakpoint 3 at 0x40053c: file ../../../src/gdb/testsuite/gdb.arch/i386-permbkpt.S, line 29.

3 breakpoint keep n 0x000000000040053c ../../../src/gdb/testsuite/gdb.arch/i386-permbkpt.S:29
But OTOH they're always enabled; there's no way to disable them...
In turn, this means that if one adds commands to such a breakpoint,
they're _always_ run:
(gdb) start
Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.arch/i386-permbkpt

29 int3
"hello!"(gdb)
IMO, one should be able to disable such a breakpoint, and GDB should
then behave just like if the user hadn't created the breakpoint in the
first place (that is, report a SIGTRAP).
By making permanent-ness a property of the location, and eliminating
the bp_permanent enum enable_state state ends up fixing that as well.
No tests are added for these changes yet; they'll be added in a follow
up patch, as skipping permanent breakpoints is currently broken and
trips on an assertion in infrun.

add a default method for gdbarch_skip_permanent_breakpoint
breakpoint.c uses gdbarch_breakpoint_from_pc to determine whether a
breakpoint location points at a permanent breakpoint:
static int
bp_loc_is_permanent (struct bp_location *loc)
{
...
addr = loc->address;
bpoint = gdbarch_breakpoint_from_pc (loc->gdbarch, &addr, &len);
...
if (target_read_memory (loc->address, target_mem, len) == 0
&& memcmp (target_mem, bpoint, len) == 0)
retval = 1;
...
So I think we should default the gdbarch_skip_permanent_breakpoint
hook to advancing the PC by the length of the breakpoint instruction,
as determined by gdbarch_breakpoint_from_pc. I believe that simple
implementation does the right thing for most architectures. If
there's an oddball architecture where that doesn't work, then it
should override the hook, just like it should be overriding the hook
if there was no default anyway.
The only two implementation of skip_permanent_breakpoint are
i386_skip_permanent_breakpoint, for x86, and
hppa_skip_permanent_breakpoint, for PA-RISC/HP-UX
The x86 implementation is trivial, and can clearly be replaced by the
new default.
I don't know about the HP-UX one though, I know almost nothing about
PA. It may well be advancing the PC ends up being equivalent.
Otherwise, it must be that "jump $pc_after_bp" doesn't work either...
Tested on x86_64 Fedora 20 native and gdbserver.

Warn users about mismatched PID namespaces
Linux supports multiple "PID namespaces". Processes in different PID
namespaces have different views of the system process list. Sometimes,
a single process can appear in more than one PID namespace, but with a
different PID in each. When GDB and its target are in different PID
namespaces, various features can break due to the mismatch between
what the target believes its PID to be and what GDB believes its PID
to be. The most visible broken functionality is thread enumeration
silently failing.
This patch explicitly warns users against trying to debug across PID
namespaces.
The patch introduced no new failures in my test suite run on an x86_64
installation of Ubuntu 14.10. It doesn't include a test: writing an
automated test that exercises this code would be very involved because
CLONE_NEWNS requires CAP_SYS_ADMIN; the easier way to reproduce the
problem is to start a new lxc container.

Avoid coff OOM
bfd_zalloc/bfd_zmalloc to fix uninitialized memory reads is too big a
hammer, when the size allocated depends on user input. A typical
bfd_alloc, bfd_seek, bfd_bread sequence will give an error or warning
at the point the file read fails when some enormous item as described
by headers is not actually present in the file. Nice operating system
allow memory overcommit. But not if you write to the memory. So
bfd_zalloc can cause an OOM, thrashing, or system hangs.
The patch also fixes a recently introduced endless loop on bad input.

When searching static symbols, gdb would search over all
expanded symtabs of all objfiles, and if that fails only then
would it search all partial/gdb_index tables of all objfiles.
This means that the user could get a random instance of the
symbol depending on what symtabs have been previously expanded.

before proceeding to the next one.

Work around GCC bug 63748
A recent change to eval.c triggered a GCC bug that causes a false positive
"may be used uninitialized" warning in evaluate_subexp_standard. This seems
to be triggered by a specific CFG constructed via setjmp and gotos.
While the GCC bug is in the process of being fixed, there are released
compiler versions (in particular GCC 4.9) in the field that show this
problem. In order to allow compiling GDB with one of those compilers,
this commit slightly reworks the CFG (in an equivalent way) of the
affected function, so that the GCC bug is no longer triggered.

Revert old nexti prologue check and eliminate in_prologue
The in_prologue check in the nexti code is obsolete; this commit
removes that, and then removes the in_prologue function as nothing
else uses it.
Looking at the code in GDB that makes use in_prologue, all we find is
this one caller:
if ((ecs->event_thread->control.step_over_calls == STEP_OVER_NONE)
|| ((ecs->event_thread->control.step_range_end == 1)
&& in_prologue (gdbarch, ecs->event_thread->prev_pc,
ecs->stop_func_start)))
{
/* I presume that step_over_calls is only 0 when we're
supposed to be stepping at the assembly language level
("stepi"). Just stop. */
/* Also, maybe we just did a "nexti" inside a prolog, so we
thought it was a subroutine call but it was not. Stop as
well. FENN */
/* And this works the same backward as frontward. MVS */

The mailing list thread is here:
https://sourceware.org/ml/gdb-patches/2001-01/msg00047.html
Not much discussion there, and no test, but looking at the code around
what was patched in that revision, we see that the checks that detect
whether the program has just stepped into a subroutine didn't rely on
the unwinders at all back then.
From 'git show 100a02e1:gdb/infrun.c':

Stripping the IN_SOLIB_RETURN_TRAMPOLINE checks for simplicity, we had:
if (stop_pc == ecs->stop_func_start /* Quick test */
|| in_prologue (stop_pc, ecs->stop_func_start)
|| ecs->stop_func_name == 0)
{
/* It's a subroutine call. */
That is, detecting a subroutine call was based on prologue detection
back then. So the in_prologue check in the current tree only made
sense back then as it was undoing a bad decision the in_prologue check
that used to exist above did.
Today, the check for a subroutine call relies on frame ids instead,
which are stable throughout the function. So we can just remove the
in_prologue check for nexti, and the whole in_prologue function along
with it.
Tested on x86_64 Fedora 20, and also by nexti-ing manually a prologue.

the names lookup_block_symbol and lookup_symbol_aux_block don't

The difference is that lookup_block_symbol lives in the lower level

read_pieced_value do big endian processing only in case of valid gdb_regnum
During armv7b testing gdb.base/store.exp test was failling with
'GDB internal error' with the following message:
Temporary breakpoint 1, wack_double (u=
../../binutils-gdb/gdb/regcache.c:177: internal-error: register_size: Assertion `regnum >= 0 && regnum < (gdbarch_num_regs (gdbarch) + gdbarch_num_pseudo_regs (gdbarch))' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
It turns out that compiler generated DWARF with non-existent
register numbers. The compiler issue is present in both little endian
(armv7) and big endian (armv7b) (it is separate issue). Here is
example for one of formal parameters of wack_double function:
<2><792>: Abbrev Number: 10 (DW_TAG_formal_parameter)
<793> DW_AT_name : u
<795> DW_AT_decl_file : 1
<796> DW_AT_decl_line : 115
<797> DW_AT_type : <0x57c>
<79b> DW_AT_location : 6 byte block: 6d 93 4 6c 93 4 (DW_OP_reg29 (r29); DW_OP_piece: 4; DW_OP_reg28 (r28); DW_OP_piece: 4)
In both big and little endian cases gdbarch_dwarf2_reg_to_regnum
returns -1 which is stored into gdb_regnum. But it causes severe
problem only in big endian case because in read_pieced_value and
write_pieced_value functions BFD_ENDIAN_BIG related processing
happen regardless of gdb_regnum value, for example register_size
function is called and in case of gdb_regnum=-1, it cause
'GDB internal error' and crash.
Solution is to move BFD_ENDIAN_BIG related processing under
(gdb_regnum != -1) branch of processing.

ARM: arm_breakpoint should be little endian form in case for arm BE8
tdep->arm_breakpoint, tdep->thumb_breakpoint, tdep->thumb2_breakpoint
should be set le_ variants in case of arm BE8 code. Those instruciton
sequences are writen to target with simple write_memory, without
regarding gdbarch_byte_order_for_code. But in BE8 case even data
memory is in big endian form, instructions are still in little endian
form.
Because of this issue there are many issues while running gdb test
case in armv7b mode. For example gdb.arch/arm-disp-step.exp test fails
because it gets SIGILL when displaced instrucion sequence reaches
break instruction, which is in wrong byte order.
Solution is to set tdep->xxx_breakpoint sequences in BE8 case (i.e
when gdbarch_byte_order_for_code is BFD_ENDIAN_BIG.

ARM: extract_arm_insn function need to read instrs correctly in be8 case
extract_arm_insn function needs to read instructions in
gdbarch_byte_order_for_code byte order, because in case armv7b,
even data is big endian, instructions are still little endian.
Currently function uses gdbarch_byte_order which would be
big endian in armv7b case.
Because of this issue pretty much all gdb.reverse/ tests are
failing with 'Process record does not support instruction' message.
Fix is to change gdbarch_byte_order to gdbarch_byte_order_for_code,
when passed to extract_unsigned_integer that reads instruction.

Match the working directory on remote host
The test in gdb.python/python.exp tests "extended-prompt" and expects
working directory is printed. However, working directory on remote
host doesn't have "gdb/testsuite", so the test fails on remote host
like:
set extended-prompt \w ^M
^M
/home/yao FAIL: gdb.python/python.exp: set extended prompt working directory (timeout)
This patch is to get the working directory first, and use it to match

and non remote host.

In response to a public outcry the strings program now defaults to using the
--all option which displays text from anywhere in the input file(s). The
default used to be --data, which only displays text from loadable data sections,
but this requires the use of the BFD library. Since the BFD library almost
certainly still contains buffer overrun and/or memory corruption bugs, and
since the strings program is often used to examine malicious code, it was
decided that the --data option option represents a possible security risk.
* strings.c: Add new command line option --data to only scan the
initialized, loadable data secions of binaries. Choose the
default behaviour of --all or --data based upon a configure
option.
* doc/binutils.texi (strings): Update documentation. Include
description of why the --data option might be unsafe.
* configure.ac: Add new option --disable-default-strings-all which

Skip tests that use cd for remote hosts
Several GDB tests change directory before compiling the test program
in order to test source file names that include directories. This
doesn't work on a remote host because default_target_compile in
DejaGnu's target.exp copies each source file with
"[remote_download host $x]" which uses "[file tail $file] to strip
off the directory of each file. If the source directory is remote
mounted on the host, this also leaves copied files in the source
directory.
A similar skip is already used in gdb.test/fullname.exp:
# We rely on being able to copy things around.
if { [is_remote host] } {
untested "setting breakpoints by full path"
return -1
}
This patch causes three GDB tests that use "cd" to be skipped for a
remote host. For gdb.base/fullpath-expand.exp this eliminates two
failures and prevents the test from leaving files fullpath-expand.c
and fullpath-expand-func.c in gdb/testsuite. For
gdb.base/realname-expand.exp it eliminates two failures. For
gdb.linespec/macro-relative.exp it prevents file macro-relative.c
from being left in gdb/testsuite/gdb.linespec/base/two.
gdb/testsuite/
* gdb.base/fullpath-expand.exp: Skip for a remote host.
* gdb.base/realname-expand.exp: Likewise.
* gdb.linespec/macro-relative.exp: Likewise.

Don't replace '\' with '\\' in before_prompt_hook
In gdb/command/prompt.py:before_prompt_hook, the '\' in the new prompt
is replaced with '\\', shown as below,
> def before_prompt_hook(self, current):
> if self.value is not '':
> newprompt = gdb.prompt.substitute_prompt(self.value)
> return newprompt.replace('\\', '\\\\')
> else:
> return None
I don't see any explanations on this in comments nor email. As doc
said, "set extended-prompt \w" substitute the current working
directory, but it prints something different from what pwd or
os.getcwdu() prints on mingw32 host.
(gdb) python print os.getcwdu()^M
\\build2-lucid-cs\yqi\yqi\arm-none-eabi
(gdb) pwd^M
Working directory \\build2-lucid-cs\yqi\yqi\arm-none-eabi
(gdb) set extended-prompt \w
\\\\build2-lucid-cs\\yqi\\yqi\\arm-none-eabi
This makes me think whether the substitution in before_prompt_hook is
necessary or not. This patch is to remove this substitution.
Run gdb.python on x86_64-linux and arm-none-eabi on mingw32 host. No
regressions.
