While thinking about it overriding some GDB _commands_ was not my intention.
There is a general assumption if I have a shell COMMAND and some FILE I can do
$ COMMAND FILE
and COMMAND will appropriately load the FILE.
FSF GDB currently needs to specify also the executable file for core files
which already inhibits this intuitive expectation. OTOH with the build-id
locating patch which could allow such intuitive start notneeding the
executable file. Still it currently did not work due to the required "-c":
$ COMMAND -c COREFILE
Entering "file", "core-file" or "attach" commands is already explicit enough
so that it IMO should do what the command name says without any
autodetections. The second command line argument
(captured_main->pid_or_core_arg) is also autodetected (for PID or CORE) but
neither "attach" accepts a core file nor "core-file" accepts a PID.
The patch makes sense only with the build-id patchset so this is not submit
for FSF GDB inclusion yet. I am fine with your patch (+/- Hui Zhu's pending
bfd_check_format_matches) as the patch below is its natural extension.
Sorry for the delay,

Subject: gdb-6.8-quit-never-aborts.patch
;; Make the GDB quit processing non-abortable to cleanup everything properly.
;;=fedora: It was useful only after gdb-6.8-attach-signalled-detach-stopped.patch .
We may abort the process of detaching threads with multiple SIGINTs - which are
being sent during a testcase terminating its child GDB.
Some of the threads may not be properly PTRACE_DETACHed which hurts if they
should have been detached with SIGSTOP (as they are accidentally left running
on the debugger termination).

Hi,
and here is the last bit for new SELinux 'deny_ptrace':
https://bugzilla.redhat.com/show_bug.cgi?id=786878
As even PTRACE_TRACEME fails in such case it needs to install hook for even
that event.
Thanks,

Subject: [patch] aout+coff: Fix strict-aliasing rules error
--IJpNTDwzlM2Ie8A6
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Hi,
https://bugzilla.redhat.com/show_bug.cgi?id=1315191 by Dan Horak
gcc (GCC) 6.0.0 20160308 (experimental)
gcc-6.0.0-0.15.fc24
gcc-6.0.0-0.15.fc25
It did compile with:
gcc-6.0.0-0.14.fc24
aoutx.h:2504:7: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
int type_code = aout_symbol (symbol)->type & 0xff;
^~~
coffcode.h:1817:3: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
coffsymbol (section->symbol)->native = native;
^~~~~~~~~~
Full log attached.
This fix is probably wrong as it drops the type safety. But ({ statements as
expressions }) are probably not allowed in GDB.

http://sourceware.org/ml/gdb-patches/2015-10/msg00301.html
Hi,
in some cases with deleted main executable GDB will want to kill the inferior.
$ cp /bin/sleep /tmp/sleep;/tmp/sleep 1h&p=$!
$ rm /tmp/sleep
$ gdb /tmp/sleep $p
GNU gdb (GDB) 7.10.50.20151016-cvs
/tmp/sleep: No such file or directory.
Attaching to process 9694
/tmp/sleep (deleted): No such file or directory.
A program is being debugged already. Kill it? (y or n) _
The first attachment of "/tmp/sleep" commandline argument errors at:
267 if (scratch_chan < 0)
268 perror_with_name (filename);
1051 if (catch_command_errors_const (exec_file_attach, execarg,
1052 !batch_flag))
Then GDB tries to attach to the process $p:
1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
This succeeds and since this moment GDB has a valid inferior. But despite that
the lines
1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
still fail because consequently attach_command() fails to find the associated
executable file:
267 if (scratch_chan < 0)
268 perror_with_name (filename);
1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
and therefore GDB executes the following:
(gdb) bt

2180 {
2181 if (!from_tty
2182 || !have_live_inferiors ()
2183 || query (_("A program is being debugged already. Kill it? ")))

2185 else
2186 error (_("Program not killed."));
2187 }
1084 catch_command_errors (core_file_command, pid_or_core_arg,

From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
From: Fedora GDB patches <invalid@email.com>

Subject: gdb-bz533176-fortran-omp-step.patch
;; Fix stepping with OMP parallel Fortran sections (BZ 533176).
;;=push+jan: It requires some better DWARF annotations.
https://bugzilla.redhat.com/show_bug.cgi?id=533176#c4
I find it a bug in DWARF and gdb behaves correctly according to it. From the
current DWARF's point of view the is a function call which you skip by "next".
If you hide any /usr/lib/debug such as using:
gdb -nx -ex 'set debug-file-directory /qwe' -ex 'file ./tpcommon_gfortran44'
and use "step" command instead of "next" there it will work.
(You need to hide debuginfo from libgomp as you would step into libgomp sources
to maintain the threads for execution.)
There should be some DWARF extension for it, currently tried to detect
substring ".omp_fn." as this function is called "MAIN__.omp_fn.0" and do not
consider such sub-function as a skippable by "next".
Another problem is that with "set scheduler-locking" being "off" (default
upstream) or "step" (default in F/RHEL) the simultaneous execution of the
threads is inconvenient. Setting it to "on" will lockup the debugging as the
threads need to get synchronized at some point. This is a more general
debugging problem of GOMP outside of the scope of this Bug.

From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
From: Tom de Vries <tdevries@suse.de>
Date: Tue, 1 Jun 2021 10:14:31 -0700
Subject: gdb-dont-overwrite-fsgsbase-m32.patch
;; Backport "[gdb/server] Don't overwrite fs/gs_base with -m32"
;; (Tom de Vries)
Consider a minimal test-case test.c:
...
int main (void) { return 0; }
...
compiled with -m32:
...
$ gcc test.c -m32
...
When running the exec using gdbserver on openSUSE Factory (currently running a
linux kernel version 5.10.5):
...
$ gdbserver localhost:12345 a.out
...
to which we connect in a gdb session, we run into a segfault in the inferior:
...
$ gdb -batch -q -ex "target remote localhost:12345" -ex continue
Program received signal SIGSEGV, Segmentation fault.
0xf7dd8bd2 in init_cacheinfo () at ../sysdeps/x86/cacheinfo.c:761
...
The segfault is caused by gdbserver overwriting $gs_base with 0 using
PTRACE_SETREGS. After it is overwritten, the next use of $gs in the inferior
will trigger the segfault.
Before linux kernel version 5.9, the value used by PTRACE_SETREGS for $gs_base
was ignored, but starting version 5.9, the linux kernel has support for
intel architecture extension FSGSBASE, which allows users to modify $gs_base,
and consequently PTRACE_SETREGS can no longer ignore the $gs_base value.
The overwrite of $gs_base with 0 is done by a memset in x86_fill_gregset,
which was added in commit 9e0aa64f551 "Fix gdbserver qGetTLSAddr for
x86_64 -m32". The memset intends to zero-extend 32-bit registers that are
tracked in the regcache to 64-bit when writing them into the PTRACE_SETREGS
data argument. But in addition, it overwrites other registers that are
not tracked in the regcache, such as $gs_base.
Fix the segfault by redoing the fix from commit 9e0aa64f551 in minimal form.
Tested on x86_64-linux:
- openSUSE Leap 15.2 (using kernel version 5.3.18):
- native
- gdbserver -m32
- -m32
- openSUSE Factory (using kernel version 5.10.5):
- native
- m32

There is a bug in that entry value code of mine, fix attached.
The testcase then PASSes with the reverted optimization by Andrew Burgess.
For the attached fix - if you nitpick the missing conditional case:
value_optimized_out (val_deref) && value_optimized_out (entryval_deref)
It is not detected there but that IMO does not matter much as
* It is for 7.8 only, for trunk it will get compared correctly thanks to the
new implementation of value_available_contents_eq()
called value_contents_eq().
* If the conditional
if (val != val_deref
&& !value_optimized_out (val_deref)
&& !value_optimized_out (entryval_deref)
&& value_available_contents_eq (val_deref, 0,
entryval_deref, 0,
TYPE_LENGTH (type_deref)))
val_equal = 1;
fails it may just print
bar (ref=@0x7fffffffd904: <optimized out>, ref@entry=@0x7fffffffd904: <optimized out>)
(or some variant with some partially optimized-out/unavailable parts)
instead of the more correct
bar (ref=ref@entry=@0x7fffffffd904: <optimized out>)
which is not much a bug.
The attached fix no longe makes sense after the new implementation
of value_available_contents_eq() called value_contents_eq() gets applied as it
handles all the optimized-out/unavailable values on its own, therefore the
attached patch is really only for 7.8.

I cannot reproduce any wrong case having the code above #if 0-ed.
I just do not find it correct to have it disabled. But at the same time I do
like much / I do not find correct the code myself. It is a bit problematic to
have struct value describing a memory content which is no longer present
there.
What happens there:
------------------------------------------------------------------------------
volatile int vv;
static __attribute__((noinline)) int
bar (int &ref) {
ref = 20;
vv++; /* break-here */
return ref;
}
int main (void) {
int var = 10;
return bar (var);
}
------------------------------------------------------------------------------

<ca> DW_AT_GNU_call_site_value: 2 byte block: 91 74 (DW_OP_fbreg: -12)
<cd> DW_AT_GNU_call_site_data_value: 1 byte block: 3a (DW_OP_lit10)
------------------------------------------------------------------------------
gdb -ex 'b value_addr' -ex r --args ../gdb ./1 -ex 'watch vv' -ex r -ex 'p &ref@entry'
->
6 return ref;
bar (ref=@0x7fffffffd944: 20, ref@entry=@0x7fffffffd944: 10) at 1.C:25
------------------------------------------------------------------------------
At /* break-here */ struct value variable 'ref' is TYPE_CODE_REF.
With FSF GDB HEAD:
(gdb) x/gx arg1.contents
0x6004000a4ad0: 0x00007fffffffd944
(gdb) p ((struct value *)arg1.location.computed.closure).lval
$1 = lval_memory
(gdb) p/x ((struct value *)arg1.location.computed.closure).location.address
$3 = 0x7fffffffd944
With your #if0-ed code:
(gdb) x/gx arg1.contents
0x6004000a4ad0: 0x00007fffffffd944
(gdb) p ((struct value *)arg1.location.computed.closure).lval
$8 = not_lval
(gdb) p/x ((struct value *)arg1.location.computed.closure).location.address
$9 = 0x0
I do not see how to access
((struct value *)arg1.location.computed.closure).location.address
from GDB CLI. Trying
(gdb) p &ref@entry
will invoke value_addr()'s:
if (TYPE_CODE (type) == TYPE_CODE_REF)
/* Copy the value, but change the type from (T&) to (T*). We
keep the same location information, which is efficient, and
allows &(&X) to get the location containing the reference. */
and therefore the address gets fetched already from
arg1.contents
and not from
((struct value *)arg1.location.computed.closure).location.address
.
And for any other type than TYPE_CODE_REF this code you #if 0-ed does not get
executed at all. This DW_AT_GNU_call_site_data_value DWARF was meant
primarily for Fortran but with -O0 entry values do not get produced
and with -Og and higher Fortran always optimizes out the passing by reference.
If you do not like the #if 0 code there I am OK with removing it as I do not
know how to make it's use reproducible for user anyway. In the worst case
- if there really is some way how to exploit it - one should just get
Attempt to take address of value not located in memory.
instead of some wrong value and it may be easy to fix then.
Thanks for the analysis,
Jan

Mark entirely optimized out value as non-lazy.
If a value is entirely optimized out, then there's nothing for
value_fetch_lazy to fetch. Sequences like:
if (value_lazy (retval))
value_fetch_lazy (retval);
End up allocating the value contents buffer, wasting memory, for no

Subject: gdb-flexible-array-member-expected-pattern.patch
;; Backport "adjust gdb.python/flexible-array-member.exp expected pattern"
;; (Simon Marchi)
The `Type.range ()` tests in gdb.python/flexible-array-member.exp pass
when the test is compiled with gcc 9 or later, but not with gcc 8 or
earlier:
$ make check TESTS="gdb.python/flexible-array-member.exp" RUNTESTFLAGS="CC_FOR_TARGET='gcc-8'"
python print(zs['items'].type.range())^M
(0, 0)^M
(gdb) FAIL: gdb.python/flexible-array-member.exp: python print(zs['items'].type.range())
python print(zso['items'].type.range())^M
(0, 0)^M
(gdb) FAIL: gdb.python/flexible-array-member.exp: python print(zso['items'].type.range())
The value that we get for the upper bound of a flexible array member
declared with a "0" size is 0 with gcc <= 8 and is -1 for gcc >= 9.
This is due to different debug info. For this member, gcc 8 does:
0x000000d5: DW_TAG_array_type
DW_AT_type [DW_FORM_ref4] (0x00000034 "int")
DW_AT_sibling [DW_FORM_ref4] (0x000000e4)
0x000000de: DW_TAG_subrange_type
DW_AT_type [DW_FORM_ref4] (0x0000002d "long unsigned int")
For the same type, gcc 9 does:
0x000000d5: DW_TAG_array_type
DW_AT_type [DW_FORM_ref4] (0x00000034 "int")
DW_AT_sibling [DW_FORM_ref4] (0x000000e5)
0x000000de: DW_TAG_subrange_type
DW_AT_type [DW_FORM_ref4] (0x0000002d "long unsigned int")
DW_AT_count [DW_FORM_data1] (0x00)
Ideally, GDB would present a consistent and documented value for an
array member declared with size 0, regardless of how the debug info
looks like. But for now, just change the test to accept the two
values, to get rid of the failure and make the test in sync
I also realized (by looking at the py-type.exp test) that calling the
fields method on an array type yields one field representing the "index"
of the array. The type of that field is of type range
(gdb.TYPE_CODE_RANGE). When calling `.range()` on that range type, it
yields the same range tuple as when calling `.range()` on the array type
itself. For completeness, add some tests to access the range tuple
through that range type as well.

* gdb.python/flexible-array-member.exp: Adjust expected range
value for member declared with 0 size. Test accessing range
tuple through range type.

Subject: [PATCH] Fix crash when expanding partial symtabs with
DW_TAG_imported_unit
PR gdb/27743 points out a gdb crash when expanding partial symtabs,
where one of the compilation units uses DW_TAG_imported_unit.
The bug is that partial_map_expand_apply expects only to be called for
the outermost psymtab. However, filename searching doesn't (and
probably shouldn't) guarantee this. The fix is to walk upward to find
the outermost CU.
A new test case is included. It is mostly copied from other test
cases, which really sped up the effort.
This bug does not occur on trunk. There,
psym_map_symtabs_matching_filename is gone, replaced by
psymbol_functions::expand_symtabs_matching. When this find a match,
it calls psymtab_to_symtab, which does this same upward walk.
Tested on x86-64 Fedora 32.
I propose checking in this patch on the gdb-10 branch, and just the
new test case on trunk.

Hi,
PR 16581:
GDB crash on inherit_abstract_dies infinite recursion
https://sourceware.org/bugzilla/show_bug.cgi?id=16581
fixed crash from an infinite recursion. But in rare cases the new code can
now gdb_assert() due to weird DWARF file.
I do not yet fully understand why the DWARF is as it is but just GDB should
never crash due to invalid DWARF anyway. The "invalid" DWARF I see only in
Fedora GCC build, not in FSF GCC build, more info at:
https://bugzilla.redhat.com/show_bug.cgi?id=1069382

[snip]
This has feature has also been reported by various users, most notably
the Fedora-EOL'd bug 1553086.
Mark Wielaard explains the issue quite nicely in
https://sourceware.org/bugzilla/show_bug.cgi?id=24717#c2
The short of it is, the ELF program headers for debuginfo files are
not suited to this particular use case. Consequently, the warning
generated above really is useless and should be ignored.
This patch follows the same heuristic that BFD itself uses.

gdb/s390: Correct recording of "store on condition" insns
The "store on condition" instructions STOC, STOCG, and STOCFH are recorded
as if their instruction formats resembled that of STG. This is wrong,
usually resulting in "failed to record execution log" errors when trying
to record code with any of these instructions.
This patch fixes the recording of these instructions.

amd64-linux-siginfo.c: Adjust include order to avoid gnulib error
On Fedora rawhide, after updating to glibc-2.33, I'm seeing the
following build failure:
CXX nat/amd64-linux-siginfo.o
In file included from /usr/include/bits/sigstksz.h:24,
from /usr/include/signal.h:315,
from ../gnulib/import/signal.h:52,
from /ironwood1/sourceware-git/rawhide-gnulib/bld/../../worktree-gnulib/gdbserver/../gdb/nat/amd64-linux-siginfo.c:20:
../gnulib/import/unistd.h:663:3: error: #error "Please include config.h first."
663 | #error "Please include config.h first."
| ^~~~~
glibc-2.33 has changed signal.h to now include <bits/sigstksz.h> which,
in turn, includes <unistd.h>. For a gdb build, this causes the gnulib
version of unistd.h to be pulled in first. The build failure shown
above happens because gnulib's config.h has not been included before
the include of <signal.h>.
The fix is simple - we just rearrange the order of the header file
includes to make sure that gdbsupport/commondefs.h is included before
attempting to include signal.h. Note that gdbsupport/commondefs.h
includes <gnulib/config.h>.
Build and regression tested on Fedora 33. On Fedora rawhide, GDB
builds again.
gdb/ChangeLog:
* nat/amd64-linux-siginfo.c: Include "gdbsupport/common-defs.h"
(which in turn includes <gnulib/config.h>) before include
of <signal.h>.

Subject: gdb-rhbz1931344-bfd_seek-elf_read_notes.patch
;; Backport "Save/restore file offset while reading notes in core file"
;; (Keith Seitz, RHBZ 1931344)
A recent bug (RH BZ 1931344) has exposed a bug in the core file
build-ID support that I introduced a while ago. It is pretty
easy to demonstate the problem following a simplified procedure
outlined in that bug:
[shell1]
shell1$ /usr/libexec/qemu-kvm
[shell2]
shell2$ pkill -SEGV -x qemu-kvm
[shell1]
Segmentation fault (core dumped)
Load this core file into GDB without specifying an executable
(an unfortunate Fedora/RHEL-ism), and GDB will inform the user
to install debuginfo for the "missing" executable:
$ gdb -nx -q core.12345
...
Missing separate debuginfo for the main executable file
Try: dnf --enablerepo='*debug*' install /usr/lib/debug/.build-id/e2/e9c66d3117fb2bbb5b2be122f04f2664e5df54
Core was generated by `/usr/libexec/qemu-kvm'.
Program terminated with signal SIGSEGV, Segmentation fault.
...
The suggested build-ID is actaully for gmp not qemu-kvm. The problem
lies in _bfd_elf_core_find_build_id, where we loop over program headers
looking for note segments:
/* Read in program headers and parse notes. */
for (i = 0; i < i_ehdr.e_phnum; ++i, ++i_phdr)
{
Elf_External_Phdr x_phdr;
if (bfd_bread (&x_phdr, sizeof (x_phdr), abfd) != sizeof (x_phdr))
goto fail;
elf_swap_phdr_in (abfd, &x_phdr, i_phdr);
if (i_phdr->p_type == PT_NOTE && i_phdr->p_filesz > 0)
{
elf_read_notes (abfd, offset + i_phdr->p_offset,
i_phdr->p_filesz, i_phdr->p_align);
if (abfd->build_id != NULL)
return TRUE;
}
elf_read_notes uses bfd_seek to forward the stream to the location of
the note segment. When control returns to _bfd_elf_core_fild_build_id,
the stream is no longer in the location looking at program headers, and
all subsequent reads will read from the wrong file offset.
To fix this, this patch marks the stream location and ensures
that it is restored after elf_read_notes is called.

;; (RH BZ 1932645).
Fix aarch64-linux-hw-point.c build problem
Due to a recent glibc header file change, the file
nat/aarch64-linux-hw-point.c no longer builds on Fedora rawhide.
An enum for PTRACE_SYSEMU is now provided by <sys/ptrace.h>. In the
past, PTRACE_SYSEMU was defined only in <asm/ptrace.h>. This is
what it looks like...
In <asm/ptrace.h>:
#define PTRACE_SYSEMU 31
In <sys/ptrace.h>:
enum __ptrace_request
{
...
PTRACE_SYSEMU = 31,
#define PT_SYSEMU PTRACE_SYSEMU
...
}
When <asm/ptrace.h> and <sys/ptrace.h> are both included in a source
file, we run into the following build problem when the former is
included before the latter:
In file included from nat/aarch64-linux-hw-point.c:26:
/usr/include/sys/ptrace.h:86:3: error: expected identifier before numeric constant
86 | PTRACE_SYSEMU = 31,
| ^~~~~~~~~~~~~
(There are more errors after this one too.)
The file builds without error when <asm/ptrace.h> is included after
<sys/ptrace.h>. I found that this is already done in
nat/aarch64-sve-linux-ptrace.h (which is included by
nat/aarch64-linux-ptrace.c).
I've tested this change on Fedora rawhide and Fedora 33, both
running on an aarch64 machine.

gdb: Convert enum range_type to a bit field enum
The expression range_type enum represents the following ideas:
- Lower bound is set to default,
- Upper bound is set to default,
- Upper bound is exclusive.
There are currently 6 entries in the enum to represent the combination
of all those ideas.
In a future commit I'd like to add stride information to the range,
this could in theory appear with any of the existing enum entries, so
this would take us to 12 enum entries.
This feels like its getting a little out of hand, so in this commit I
switch the range_type enum over to being a flags style enum. There's
one entry to represent no flags being set, then 3 flags to represent
the 3 ideas above. Adding stride information will require adding only
one more enum flag.
I've then gone through and updated the code to handle this change.
There should be no user visible changes after this commit.

Subject: gdb-rhbz1964167-fortran-array-strides-in-expressions.patch
;; [fortran] Backport Andrew Burgess's commit which adds support
;; for array strides in expressions.
gdb/fortran: add support for parsing array strides in expressions
With this commit GDB now understands the syntax of Fortran array
strides, a user can type an expression including an array stride, but
they will only get an error informing them that array strides are not
supported.
This alone is an improvement on what we had before in GDB, better to
give the user a helpful message that a particular feature is not
supported than to just claim a syntax error.
Before:
(gdb) p array (1:10:2, 2:10:2)
A syntax error in expression, near `:2, 2:10:2)'.
Now:
(gdb) p array (1:10:2, 2:10:2)
Fortran array strides are not currently supported
Later commits will allow GDB to handle array strides correctly.
gdb/ChangeLog:
* expprint.c (dump_subexp_body_standard): Print RANGE_HAS_STRIDE.
* expression.h (enum range_type): Add RANGE_HAS_STRIDE.
* f-exp.y (arglist): Allow for a series of subranges.
(subrange): Add cases for subranges with strides.

Subject: gdb-rhbz1964167-fortran-clean-up-array-expression-evaluation.patch
;; [fortran] Backport Andrew Burgess's commit which cleans up
;; array/string expression evaluation.
gdb/fortran: Clean up array/string expression evaluation
This commit is a refactor of part of the Fortran array and string
handling code.
The current code is split into two blocks, linked, weirdly, with a
goto. After this commit all the code is moved to its own function,
and arrays and strings are now handled using the same code; this will
be useful later when I want to add array stride support where strings
will want to be treated just like arrays, but is a good clean up even
without the array stride work, which is why I'm merging it now.
For now the new function is added as a static within eval.c, even
though the function is Fortran only. A following commit will remove
some of the Fortran specific code from eval.c into one of the Fortran
specific files, including this new function.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* eval.c (fortran_value_subarray): New function, content is taken
from...
(evaluate_subexp_standard): ...here, in two places. Now arrays
and strings both call the new function.
(calc_f77_array_dims): Add header comment, handle strings.

From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
From: Kevin Buettner <kevinb@redhat.com>
Date: Mon, 24 May 2021 17:07:36 -0700
Subject: gdb-rhbz1964167-fortran-whitespace_array.patch
;; [fortran] Backport Andrew Burgess's commit which eliminates undesirable
;; whitespace when printing arrays.
gdb/fortran: Change whitespace when printing arrays
This commit makes the whitespace usage when printing Fortran arrays
more consistent, and more inline with how we print C arrays.
Currently a 2 dimensional Fotran array is printed like this, I find
the marked whitespace unpleasant:
(( 1, 2, 3) ( 4, 5, 6) )
^ ^ ^
After this commit the same array is printed like this:
((1, 2, 3) (4, 5, 6))
Which seems more inline with how we print C arrays, in the case of C
arrays we don't add extra whitespace before the first element.
gdb/ChangeLog:
* f-valprint.c (f77_print_array_1): Adjust printing of whitespace
for arrays.
gdb/testsuite/ChangeLog:
* gdb.fortran/array-slices.exp: Update expected results.
* gdb.fortran/class-allocatable-array.exp: Likewise.
* gdb.fortran/multi-dim.exp: Likewise.
* gdb.fortran/vla-type.exp: Likewise.
* gdb.mi/mi-vla-fortran.exp: Likewise.

Subject: gdb-rhbz1964167-move-fortran-expr-handling.patch
;; [fortran] Backport Andrew Burgess's commit which moves Fortran
;; expression handling to f-lang.c.
gdb/fortran: Move Fortran expression handling into f-lang.c
The Fortran specific OP_F77_UNDETERMINED_ARGLIST is currently handled
in the generic expression handling code. There's no reason why this
should be the case, so this commit moves handling of this into Fortran
specific files.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* eval.c: Remove 'f-lang.h' include.
(value_f90_subarray): Moved to f-lang.c.
(eval_call): Renamed to...
(evaluate_subexp_do_call): ...this, is no longer static, header
comment moved into header file.
(evaluate_funcall): Update call to eval_call.
(skip_undetermined_arglist): Moved to f-lang.c.
(fortran_value_subarray): Likewise.
(evaluate_subexp_standard): OP_F77_UNDETERMINED_ARGLIST handling
moved to evaluate_subexp_f.
(calc_f77_array_dims): Moved to f-lang.c
* expprint.c (print_subexp_funcall): New function.
(print_subexp_standard): OP_F77_UNDETERMINED_ARGLIST handling
moved to print_subexp_f, OP_FUNCALL uses new function.
(dump_subexp_body_funcall): New function.
(dump_subexp_body_standard): OP_F77_UNDETERMINED_ARGLIST handling
moved to dump_subexp_f, OP_FUNCALL uses new function.
* expression.h (evaluate_subexp_do_call): Declare.
* f-lang.c (value_f90_subarray): Moved from eval.c.
(skip_undetermined_arglist): Likewise.
(calc_f77_array_dims): Likewise.
(fortran_value_subarray): Likewise.
(evaluate_subexp_f): Add OP_F77_UNDETERMINED_ARGLIST support.
(operator_length_f): Likewise.
(print_subexp_f): Likewise.
(dump_subexp_body_f): Likewise.
* fortran-operator.def (OP_F77_UNDETERMINED_ARGLIST): Move
declaration of this operation to here.
* parse.c (operator_length_standard): OP_F77_UNDETERMINED_ARGLIST
support moved to operator_length_f.
* parser-defs.h (dump_subexp_body_funcall): Declare.
(print_subexp_funcall): Declare.
* std-operator.def (OP_F77_UNDETERMINED_ARGLIST): Moved to
fortran-operator.def.

;; Backport "Fix gdb.fortran/array-slices.exp with -m32"
;; (Tom de Vres)
commit 10f92414d6d4a5f8eb8cbb2bf39ca86c1f9c1da5
Author: Tom de Vries <tdevries@suse.de>
Date: Fri Jan 15 12:14:45 2021 +0100
[gdb/testsuite] Fix gdb.fortran/array-slices.exp with -m32
When running test-case gdb.fortran/array-slices.exp with target board
unix/-m32, we run into:
...
(gdb) print /x &array4d^M
$69 = 0xffffb620^M
(gdb) print /x (&array4d) + sizeof (array4d)^M
$70 = 0x95c620^M
(gdb) FAIL: gdb.fortran/array-slices.exp: repack=on: test 9: check sizes match
...
The expressions calculate the start and end of an array, but the calculation
of the end expression has an unexpected result (given that it lies before the
start of the array). By printing "sizeof (array4d)" as a separate
expression:
...
(gdb) print /x sizeof (array4d)
$1 = 0xc40
...
it becomes clear we expected to get 0xffffb620 + 0xc40 == 0xffffc260 instead.
The problem is that using the '&' returns a pointer type:
...
(gdb) p &array4d
$5 = (PTR TO -> ( integer(kind=4) (-3:3,7:10,-3:3,-10:-7) )) 0xffffbe00
...
which has the consequence that the addition is done as pointer arithmetic.
Fix this by using the result of "print /x &array4d" instead of &array4d in the
addition.
Tested on x86_64-linux.

Remove C/C++ relevant code in Fortran specific file.
Remove code relevant for printing C/C++ Integer values in a
Fortran specific file to unify printing of Fortran values.
This does not change the output.
And adjust its testcase.

I have it reproducible on Fedora 20 i686 with plain
CFLAGS=-g ./configure;make;cd gdb/testsuite;make site.exp;runtest gdb.fortran/dynamic-other-frame.exp
Besides that I have updated the testcase with
gdb_test_no_output "set print frame-arguments all"
so that there is no longer needed the patch:
[patch] Display Fortran strings in backtraces
https://sourceware.org/ml/gdb-patches/2014-07/msg00709.html
The fix below has no regressions for me. Unfortunately I do not see why you
cannot reproduce it.
Thanks,
Jan

[gdb/symtab] Handle DW_TAG_type_unit in process_psymtab_comp_unit
When running test-case gdb.cp/cpexprs-debug-types.exp with target board
unix/gdb:debug_flags=-gdwarf-5, I run into:
...
(gdb) file cpexprs-debug-types^M
Reading symbols from cpexprs-debug-types...^M
ERROR: Couldn't load cpexprs-debug-types into GDB (eof).
ERROR: Couldn't send delete breakpoints to GDB.
ERROR: GDB process no longer exists
GDB process exited with wait status 23054 exp9 0 0 CHILDKILLED SIGABRT SIGABRT
...
We're running into this abort in process_psymtab_comp_unit:
...
switch (reader.comp_unit_die->tag)
{
case DW_TAG_compile_unit:
this_cu->unit_type = DW_UT_compile;
break;
case DW_TAG_partial_unit:
this_cu->unit_type = DW_UT_partial;
break;
default:
abort ();
}
...
because reader.comp_unit_die->tag == DW_TAG_type_unit.
Fix this by adding a DW_TAG_type_unit case.
Tested on x86_64-linux.
