+2005-02-28  Jeff Johnston  <jjohnstn@redhat.com>
+
+	* config/i386/nm-linux.h: Change dr register routines to
+	accept a ptid_t first argument.  Change all calling macros
+	to default the inferior_ptid for the first argument.
+	(i386_linux_insert_watchpoint): New prototype.
+	(i386_linux_remove_watchpoint, i386_linux_insert_hw_breakpoint): Ditto.
+	(i386_linux_remove_hw_breakpoint): Ditto.
+	(target_insert_watchpoint, target_remove_watchpoint): Undef and
+	override.
+	(target_insert_hw_breakpoint, target_remove_hw_breakpoint): Ditto.
+	* config/i386/nm-linux64.h: Ditto except add amd64 versions of
+	the watchpoint/hw-breakpoint insert/remove routines.
+	* i386-nat.c: Include "inferior.h" to define inferior_ptid.
+	* i386-linux-nat.c: Change all dr get/set routines to accept
+	ptid_t as first argument and to use this argument to determine
+	the tid for PTRACE.
+	(i386_linux_set_debug_regs_for_thread): New function.
+	(i386_linux_sync_debug_registers_callback): Ditto.

+	* testsuite/gdb.threads/watchthreads-threaded.exp: Ditto.
+
+[ With recent upstream GDB (6.8) reduced only to the testcase.  ]
+
+[ It was called watchthreads2.{exp,c} before but it conflicted with FSF GDB new

+
+FIXME: The testcase does not expects multiple watchpoints hits per one stop.

++ * The point of this program is to crash in a multi-threaded app.

++ * * In a syscall
++ * * In a syscall inside a signal handler
++ * * In a syscall inside a signal handler executing on the altstack
++ * * Finally, the main thread crashes in main, with no frills.

+Subject: gdb-6.5-bz185337-resolve-tls-without-debuginfo-v2.patch
+
+;; Support TLS symbols (+`errno' suggestion if no pthread is found) (BZ 185337).
+;;=push+jan: It should be replaced by Infinity project.
+
+https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=185337
+
+2008-02-24  Jan Kratochvil  <jan.kratochvil@redhat.com>
+
+	Port to GDB-6.8pre.
+
+currently for trivial nonthreaded helloworld with no debug info up to -ggdb2 you
+will get:
+        (gdb) p errno
+        [some error]
+
+* with -ggdb2 and less "errno" in fact does not exist anywhere as it was
+  compiled to "(*__errno_location ())" and the macro definition is not present.
+  Unfortunately gdb will find the TLS symbol and it will try to access it but
+  as the program has been compiled without -lpthread the TLS base register
+  (%gs on i386) is not setup and it will result in:
+        Cannot access memory at address 0x8
+
+Attached suggestion patch how to deal with the most common "errno" symbol
+for the most common under-ggdb3 compiled programs.
+
+Original patch hooked into target_translate_tls_address.  But its inferior
+call invalidates `struct frame *' in the callers - RH BZ 690908.

+	DW_AT_MIPS_linkage_name over DW_AT_name now only for non-C.

+then gdb would fail to match the shared library name during the TLS lookup.

+
+  This is the fix for RH BZ #981154
+
+  It is mainly a testcase addition, but a minor fix in the gdb/build-id.c
+  file was also needed.
+
+  gdb/build-id.c was added by:
+
+  commit dc294be54c96414035eed7d53dafdea0a6f31a72
+  Author: Tom Tromey <tromey@redhat.com>
+  Date:   Tue Oct 8 19:56:15 2013 +0000
+
+  and had a little thinko there.  The variable 'filename' needs to be set to
+  NULL after it is free'd, otherwise the code below thinks that it is still
+  valid and doesn't print the necessary warning ("Try: yum install ...").

gdb-dont-overwrite-fsgsbase-m32.patch

+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):

+;; 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.

+
+Hi,
+
+for Fortran it fixes displaying normal strings also in frames/backtraces:
+
+(gdb) frame
+->
+
+The patch is simple and I do not see why it should not be this way.
+
+For C/C++ TYPE_CODE_STRING is not used.  I am not aware of Pascal but that
+language is currently not really much supported in GDB anyway.
+
+This was a part of my archer/jankratochvil/vla branch but it is not a part of
+the Intel VLA patchset as it in fact is completely unrelated to "VLA".
+
+No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
+
+Thanks,
+Jan

+   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.

+.SH NAME
+gstack \- print a stack trace of a running process
+
+.SH SYNOPSIS
+.B gstack
+pid
+
+.SH DESCRIPTION
+
+\f3gstack\f1 attaches to the active process named by the \f3pid\f1 on
+the command line, and prints out an execution stack trace.  If ELF
+symbols exist in the binary (usually the case unless you have run
+strip(1)), then symbolic addresses are printed as well.
+
+If the process is part of a thread group, then \f3gstack\f1 will print
+out a stack trace for each of the threads in the group.
+

+Original message by Tom Tromey:

+  <https://sourceware.org/ml/gdb-patches/2012-03/msg00955.html>
+  Message-ID: <871uoc1va3.fsf@fleche.redhat.com>
+
+Comment from Sergio Durigan Junior:
+
+  In order to correctly test this patch, I wrote a testcase based on Jan
+  Kratochvil's <gdb/testsuite/gdb.base/gcore-excessive-memory.exp>.  The
+  testcase, which can be seen below, tests GDB in order to see if the
+  amount of memory being leaked is minimal, as requested in the bugzilla.
+  It is hard to define what "minimum" is, so I ran the testcase on all
+  supported RHEL architectures and came up with an average.

+
+;; Fix '`catch syscall' doesn't work for parent after `fork' is called'
+;; (Philippe Waroquiers, RH BZ 1149205).
+;;=fedoratest
+
+URL: <https://sourceware.org/ml/gdb-patches/2013-05/msg00364.html>
+Message-ID: <1368136582.30058.7.camel@soleil>
+
+  From: Philippe Waroquiers <philippe dot waroquiers at skynet dot be>
+  To: gdb-patches at sourceware dot org
+  Subject: RFA: fix gdb_assert caused by 'catch signal ...' and fork
+  Date: Thu, 09 May 2013 23:56:22 +0200
+
+  The attached patch fixes a gdb_assert caused by the combination of catch
+  signal and fork:
+    break-catch-sig.c:152: internal-error: signal_catchpoint_remove_location: Assertion `signal_catch_counts[iter] > 0' failed.
+
+  The problem is that the signal_catch_counts is decremented by detach_breakpoints.
+  The fix consists in not detaching breakpoint locations of type bp_loc_other.
+  The patch introduces a new test.
+
+Comments by Sergio Durigan Junior:
+
+  I addded a specific testcase for this patch, which tests exactly the
+  issue that the customer is facing.  This patch does not solve the
+  whole problem of catching a syscall and forking (for more details,
+  see <https://sourceware.org/bugzilla/show_bug.cgi?id=13457>,
+  specifically comment #3), but it solves the issue reported by the
+  customer.
+
+  I also removed the original testcase of this patch, because it
+  relied on "catch signal", which is a command that is not implemented
+  in this version of GDB.

+;; Fix 'backport GDB 7.4 fix to RHEL 6.6 GDB' [Original Sourceware bug
+;; description: 'C++ (and objc): Internal error on unqualified name
+;; re-set', PR 11657] (RH BZ 1186476).
+;;=fedoratest
+
+Comments from Sergio Durigan Junior:
+
+  The "proper" fix for this whole problem would be to backport the
+  "ambiguous linespec" patch series.  However, it is really not
+  recommended to do that for RHEL GDB, because the patch series is too
+  big and could introduce unwanted regressions.  Instead, what we
+  chose to do was to replace the gdb_assert call by a warning (which
+  allows the user to continue the debugging session), and tell the
+  user that, although more than one location was found for his/her
+  breakpoint, only one will be used.

+
+    Exclude debuginfo files from "outside of ELF segments" warning
+
+    When GDB loads an ELF file, it will warn when a section is not located
+    in an ELF segment:
+
+    $ ./gdb -q -iex "set build-id-verbose 0" --ex "b systemctl_main" -ex "r" -batch --args systemctl kexec

+      in .gnu_debugdata for /lib64/libip4tc.so.2
+    [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.

+
+;; Backport fix for frame_id_p assertion failure (RH BZ 1909902).
+
+Make scoped_restore_current_thread's cdtors exception free (RFC)
+
+If the remote target closes while we're reading registers/memory for
+restoring the selected frame in scoped_restore_current_thread's dtor,
+the corresponding TARGET_CLOSE_ERROR error is swallowed by the
+scoped_restore_current_thread's dtor, because letting exceptions
+escape from a dtor is bad.  It isn't great to lose that errors like
+that, though.  I've been thinking about how to avoid it, and I came up
+with this patch.
+
+The idea here is to make scoped_restore_current_thread's dtor do as
+little as possible, to avoid any work that might throw in the first
+place.  And to do that, instead of having the dtor call
+restore_selected_frame, which re-finds the previously selected frame,
+just record the frame_id/level of the desired selected frame, and have
+get_selected_frame find the frame the next time it is called.  In
+effect, this implements most of Cagney's suggestion, here:
+
+  /* On demand, create the selected frame and then return it.  If the
+     selected frame can not be created, this function prints then throws
+     an error.  When MESSAGE is non-NULL, use it for the error message,
+     otherwize use a generic error message.  */
+  /* FIXME: cagney/2002-11-28: At present, when there is no selected
+     frame, this function always returns the current (inner most) frame.
+     It should instead, when a thread has previously had its frame
+     selected (but not resumed) and the frame cache invalidated, find
+     and then return that thread's previously selected frame.  */
+  extern struct frame_info *get_selected_frame (const char *message);
+
+The only thing missing to fully implement that would be to make
+reinit_frame_cache just clear selected_frame instead of calling
+select_frame(NULL), and the call select_frame(NULL) explicitly in the
+places where we really wanted reinit_frame_cache to go back to the
+current frame too.  That can done separately, though, I'm not
+proposing to do that in this patch.
+
+Note that this patch renames restore_selected_frame to
+lookup_selected_frame, and adds a new restore_selected_frame function
+that doesn't throw, to be paired with the also-new save_selected_frame
+function.
+
+There's a restore_selected_frame function in infrun.c that I think can
+be replaced by the new one in frame.c.
+
+Also done in this patch is make the get_selected_frame's parameter be
+optional, so that we don't have to pass down nullptr explicitly all
+over the place.
+
+lookup_selected_frame should really move from thread.c to frame.c, but
+I didn't do that here, just to avoid churn in the patch while it
+collects comments.  I did make it extern and declared it in frame.h
+already, preparing for the move.  I will do the move as a follow up
+patch if people agree with this approach.
+
+Incidentally, this patch alone would fix the crashes fixed by the
+previous patches in the series, because with this,
+scoped_restore_current_thread's constructor doesn't throw either.

+Fix frame cycle detection
+
+The recent commit to make scoped_restore_current_thread's cdtors

+
+  Breakpoint 1, 0x00000000004012bb in eh2 (gdb/frame.c:641: internal-error: frame_id get_frame_id(frame_info*): Assertion `stashed' failed.
+  A problem internal to GDB has been detected,
+  further debugging may prove unreliable.
+  Quit this debugging session? (y or n) FAIL: gdb.base/eh_return.exp: hit breakpoint (GDB internal error)
+
+That testcase uses __builtin_eh_return and, before the regression, the
+backtrace at eh2 looked like this:
+
+ (gdb) bt
+ #0  0x00000000004006eb in eh2 (p=0x4006ec <continuation>) at src/gdb/testsuite/gdb.base/eh_return.c:54
+ Backtrace stopped: previous frame identical to this frame (corrupt stack?)
+
+That "previous frame identical to this frame" is caught by the cycle
+detection based on frame id.
+
+The assertion failing is this one:
+
+ 638           /* Since this is the first frame in the chain, this should
+ 639              always succeed.  */

+Before the commit to make scoped_restore_current_thread's cdtors
+exception free, scoped_restore_current_thread's dtor would call
+get_frame_id on the selected frame, and we use
+scoped_restore_current_thread pervasively.  That had the side effect
+of stashing the frame id of frame #0 before reaching the path shown in
+the backtrace.  I.e., the frame id of frame #0 happened to be stashed
+before the frame id of frame #1.  But that was by chance, not by
+design.
+

+
+  commit 256ae5dbc73d1348850f86ee77a0dc3b04bc7cc0

+  AuthorDate: Mon Oct 31 12:47:42 2016 -0700
+
+      Stash frame id of current frame before stashing frame id for previous frame
+
+Fixed a similar problem, by making sure get_prev_frame computes the
+frame id of the current frame before unwinding the previous frame, so
+that the cycle detection works properly.  That fix misses the scenario
+we're now running against, because if you notice, the backtrace above
+shows that frame #4 calls get_prev_frame_always, not get_prev_frame.
+I.e., nothing is calling get_frame_id on the current frame.
+
+The fix here is to move Kevin's fix down from get_prev_frame to
+get_prev_frame_always.  Or actually, a bit further down to
+get_prev_frame_always_1 -- note that inline_frame_this_id calls
+get_prev_frame_always, so we need to be careful to avoid recursion in
+that scenario.
+
+gdb/ChangeLog:
+
+	* frame.c (get_prev_frame): Move get_frame_id call from here ...
+	(get_prev_frame_always_1): ... to here.
+	* inline-frame.c (inline_frame_this_id): Mention
+	get_prev_frame_always_1 in comment.

+
+;; 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.

+;; Backport change which fixes gdbserver testing hang on f34 and rawhide.
+
+Fix potential hang during gdbserver testing
+
+We're currently seeing testing of native-extended-gdbserver hang while
+testing the x86_64 architecture on both Fedora 34 and Fedora Rawhide.
+The test responsible for the hang is gdb.threads/fork-plus-threads.exp.
+
+While there is clearly a problem/bug with this test on F34 and
+Rawhide, it's also the case that testing should not hang.  This commit
+prevents the hang by waiting with the "-nowait" flag in
+close_gdbserver.
+
+The -nowait flag is also used in the kill_wait_spawned_process proc in
+gdb/testsuite/lib/gdb.exp, so there is precedent for doing this.
+
+There are also 15 other uses of "wait -i" scattered throughout the
+test suite.  While it's tempting to change these to also use the
+-nowait flag, I think it might be safer to defer doing so until we
+actually see a problem.
+
+I've tested this patch on Fedora 32, 33, 34, and Rawhide.  Results are
+comparable on Fedora 32 and 33.  On Fedora 34 and Rawhide, with this
+commit in place, testing completes when the target_board is
+native-extended-gdbserver.  On those OSes, when not using this commit,
+testing usually hangs due to a problem with
+gdb.threads/fork-plus-threads.exp.  I've also tested on all of the
+mentioned OSes with target_board=native-gdbserver; for that testing,
+I achieved comparable results over a number of runs.  (Unfortunately
+results are rarely identical due to racy tests.)

+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.

+
+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.
+	* f-lang.c (value_f90_subarray): Catch use of array strides and
+	throw an error.
+	* parse.c (operator_length_standard): Handle RANGE_HAS_STRIDE.
+
+gdb/testsuite/ChangeLog:
+
+	* gdb.fortran/array-slices.exp: Add a new test.

+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.

+
+gdb: rename 'enum range_type' to 'enum range_flag'
+
+To avoid confusion with other parts of GDB relating to types and
+ranges, rename this enum to make it clearer that it is a set of
+individual flags rather than an enumeration of different types of
+range.
+
+There should be no user visible changes after this commit.
+
+gdb/ChangeLog:
+
+	* expprint.c (print_subexp_standard): Change enum range_type to
+	range_flag and rename variables to match.
+	(dump_subexp_body_standard): Likewise.
+	* expression.h (enum range_type): Rename to...
+	(enum range_flag): ...this.
+	(range_types): Rename to...
+	(range_flags): ...this.
+	* f-lang.c (value_f90_subarray): Change enum range_type to
+	range_flag and rename variables to match.
+	* parse.c (operator_length_standard): Likewise.
+	* rust-exp.y (rust_parser::convert_ast_to_expression): Change enum
+	range_type to range_flag.
+	* rust-lang.c (rust_evaluate_funcall): Likewise.
+	(rust_range): Likewise.
+	(rust_compute_range): Likewise.
+	(rust_subscript): Likewise.

+;; 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.

+From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
+From: Kevin Buettner <kevinb@redhat.com>
+Date: Mon, 24 May 2021 17:00:17 -0700
+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.

+Subject: gdb-rhbz2019936-gdbserver-avx512-m32.patch
+
+;; Backport "Fix avx512 -m32 support in gdbserver"
+;; (Tom de Vries, RHBZ 2019936)
+
+    PR27257 reports a problem that can be reproduced as follows:
+    - use x86_64 machine with avx512 support
+    - compile a hello world with -m32 to a.out
+    - start a gdbserver session with a.out
+    - use gdb to connect to the gdbserver session
+
+    This makes us run into:
+    ...
+    Listening on port 2346
+    Remote debugging from host ::1, port 34940
+    src/gdbserver/regcache.cc:257: \
+      A problem internal to GDBserver has been detected.
+    Unknown register zmm16h requested
+    ...
+
+    The problem is that i387_xsave_to_cache in gdbserver/i387-fp.cc can't find a
+    register zmm16h in the register cache.
+
+    To understand how this happens, first some background.
+
+    SSE has 16 128-bit wide xmm registers.
+
+    AVX extends the SSE registers set as follows:
+    - it extends the 16 existing 128-bit wide xmm registers to 256-bit wide ymm
+      registers.
+
+    AVX512 extends the AVX register set as follows:
+    - it extends the 16 existing 256-bit wide ymm registers to 512-bit wide zmm
+      registers.
+    - it adds 16 additional 512-bit wide zmm registers (with corresponding ymm and
+      xmm subregisters added as well)
+
+    However, in 32-bit mode, there are only 8 xmm/ymm/zmm registers.
+
+    The problem we're running into is that gdbserver/i387-fp.cc uses these
+    constants to describe the size of the register file:
+    ...
+    static const int num_avx512_zmmh_low_registers = 16;
+    static const int num_avx512_zmmh_high_registers = 16;
+    static const int num_avx512_ymmh_registers = 16;
+    static const int num_avx512_xmm_registers = 16;
+    ...
+    which are all incorrect for the 32-bit case.
+
+    Fix this by replacing the constants with variables that have the appropriate
+    values in 64-bit and 32-bit mode.
+
+    Tested on x86_64-linux with native and unix/-m32.

+One has to also use -fPIC rather than -fPIE, -fPIC is stronger.

+The correct way would be:
+make check//unix RUNTESTFLAGS='CC_FOR_TARGET=gcc\ -fPIC\ -pie CXX_FOR_TARGET=g++\ -fPIC\ -pie solib-display.exp'

+but this has caused a different regression (as discussed in the confcall).
+
+QUICK_ADDRMAP is built only from .debug_aranges.  But we can have existing
+built .debug_aranges for CUs in OBJFILE but still some CUs do not need to have
+DWARF at all while they can feature CFIs (.eh_frame or .debug_frame).
+It has been described by Daniel Jacobowitz at:
+	Re: [2/4] RFC: check psymtabs_addrmap before reading FDEs
+	http://sourceware.org/ml/gdb-patches/2010-07/msg00012.html
+
+Sorry for this regression by me (in that fix of a different regression).
+
+Fixed it the "slow way" as this branch is now obsoleted by .gdb-index.
+
+No regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu.
+
+Checked-in.
+
+Thanks,
+Jan
