From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
From: Jan Kratochvil <jan.kratochvil@redhat.com>

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.

Subject: gdb-6.5-sharedlibrary-path.patch
;; Fix TLS symbols resolving for shared libraries with a relative pathname.
;; The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
;;=fedoratest: One should recheck if it is really fixed upstream.
If you provided some relative path to the shared library, such as with
export LD_LIBRARY_PATH=.
then gdb would fail to match the shared library name during the TLS lookup.
Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed?
The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'.
The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
2006-09-01 Jan Kratochvil <jan.kratochvil@redhat.com>
* solib-svr4.c (svr4_fetch_objfile_link_map): Match even absolute
requested pathnames to the internal loaded relative pathnames.
2007-10-16 Jan Kratochvil <jan.kratochvil@redhat.com>
Port to GDB-6.7.

Subject:
gdb-6.6-buildid-locate-misleading-warning-missing-debuginfo-rhbz981154.patch
;; Fix 'gdb gives highly misleading error when debuginfo pkg is present,
;; but not corresponding binary pkg' (RH BZ 981154).
;;=push+jan
Comments by Sergio Durigan Junior <sergiodj@redhat.com>:
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 ...").

Subject: gdb-fortran-frame-string.patch
;; Display Fortran strings in backtraces.
;;=fedoratest
http://sourceware.org/ml/gdb-patches/2014-07/msg00709.html
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

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.

Subject: gdb-rhbz-853071-update-manpages.patch
;; Backport manpage update
[gdb/doc]: Updated manpages to be consistent with help
Updated manpages to be consistent with help information provided by the
binary. The main changes are:
* Making all long-form options have '--', instead of a single '-';
* added most of the missing options to the manpage;
* removed the information about using '+' instead of '-', since it
doesn't seem to be supported anymore.
This also fixes 2 upstream bugs:
* https://sourceware.org/bugzilla/show_bug.cgi?id=23965; by adding
--args to the manpage
* https://sourceware.org/bugzilla/show_bug.cgi?id=10619; by adding the
double dashes

Subject: gdb-rhbz1007614-memleak-infpy_read_memory-test.patch
;; Fix 'memory leak in infpy_read_memory()' (RH BZ 1007614)
;;=fedoratest
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.

Subject: gdb-rhbz1149205-catch-syscall-after-fork-test.patch
;; 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>

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.

Subject: gdb-rhbz1186476-internal-error-unqualified-name-re-set-test.patch
;; 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.

under some circumstances.
Fixes bug 28030.

[gdb/testsuite] Fix FAIL in gdb.mi/mi-var-child-f.exp
When running test-case gdb.mi/mi-var-child-f.exp on openSUSE Tumbleweed
(with glibc 2.34) I run into:
...
(gdb) ^M
PASS: gdb.mi/mi-var-child-f.exp: mi runto prog_array
Expecting: ^(-var-create array \* array[^M
]+)?(\^done,name="array",numchild="[0-9]+",value=".*",type=.*,has_more="0"[^M

&"Attempt to use a type name as an expression.\n"^M
^error,msg="-var-create: unable to create variable object"^M
(gdb) ^M
FAIL: gdb.mi/mi-var-child-f.exp: create local variable array (unexpected output)
...
The problem is that the name array is used both:
- as the name for a local variable
- as the name of a type in glibc, in file malloc/dynarray-skeleton.c, as included
by nss/nss_files/files-hosts.c.
Fix this by ignoring the shared lib symbols.
Likewise in a couple of other fortran tests.
Tested on x86_64-linux.

;; Backport fix for dprintf bug (RH BZ 2022177).
Fix PR 28308 - dprintf breakpoints not working when run from script
This commit fixes Bug 28308, titled "Strange interactions with
dprintf and break/commands":
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28308
Since creating that bug report, I've found a somewhat simpler way of
reproducing the problem. I've encapsulated it into the GDB test case
which I've created along with this bug fix. The name of the new test
is gdb.base/dprintf-execution-x-script.exp, I'll demonstrate the
problem using this test case, though for brevity, I've placed all
relevant files in the same directory and have renamed the files to all
start with 'dp-bug' instead of 'dprintf-execution-x-script'.
The script file, named dp-bug.gdb, consists of the following commands:
dprintf increment, "dprintf in increment(), vi=%d\n", vi
break inc_vi
commands
continue
end
run
Note that the final command in this script is 'run'. When 'run' is
instead issued interactively, the bug does not occur. So, let's look
at the interactive case first in order to see the correct/expected
output:
$ gdb -q -x dp-bug.gdb dp-bug
... eliding buggy output which I'll discuss later ...
(gdb) run
Starting program: /mesquite2/sourceware-git/f34-master/bld/gdb/tmp/dp-bug
vi=0
dprintf in increment(), vi=0

26 in dprintf-execution-x-script.c
vi=3
[Inferior 1 (process 1539210) exited normally]
In this run, in which 'run' was issued from the gdb prompt (instead
of at the end of the script), there are three dprintf messages along
with three 'Breakpoint 2' messages. This is the correct output.
Now let's look at the output that I snipped above; this is the output
when 'run' is issued from the script loaded via GDB's -x switch:
$ gdb -q -x dp-bug.gdb dp-bug
Reading symbols from dp-bug...
Dprintf 1 at 0x40116e: file dprintf-execution-x-script.c, line 38.

26 in dprintf-execution-x-script.c
vi=3
[Inferior 1 (process 1539175) exited normally]
In the output shown above, only the first dprintf message is printed.
The 2nd and 3rd dprintf messages are missing! However, all three
'Breakpoint 2...' messages are still printed.
Why does this happen?
bpstat_do_actions_1() in gdb/breakpoint.c contains the following
comment and code near the start of the function:
/* Avoid endless recursion if a `source' command is contained
in bs->commands. */
if (executing_breakpoint_commands)
return 0;
scoped_restore save_executing
= make_scoped_restore (&executing_breakpoint_commands, 1);
Also, as described by this comment prior to the 'async' field
in 'struct ui' in top.h, the main UI starts off in sync mode
when processing command line arguments:
/* True if the UI is in async mode, false if in sync mode. If in
sync mode, a synchronous execution command (e.g, "next") does not
return until the command is finished. If in async mode, then
running a synchronous command returns right after resuming the
target. Waiting for the command's completion is later done on
the top event loop. For the main UI, this starts out disabled,
until all the explicit command line arguments (e.g., `gdb -ex
"start" -ex "next"') are processed. */
This combination of things, the state of the static global
'executing_breakpoint_commands' plus the state of the async
field in the main UI causes this behavior.
This is a backtrace after hitting the dprintf breakpoint for
the second time when doing 'run' from the script file, i.e.
non-interactively:

There are two frames for bpstat_do_actions_1(), one at frame #16 and
the other at frame #0. The one at frame #16 is processing the actions
for Breakpoint 2, which is a 'continue'. The one at frame #0 is attempting
to process the dprintf breakpoint action. However, at this point,
the value of 'executing_breakpoint_commands' is 1, forcing an early
return, i.e. prior to executing the command(s) associated with the dprintf
breakpoint.
For the sake of comparison, this is what the stack looks like when hitting
the dprintf breakpoint for the second time when issuing the 'run'
command from the GDB prompt.

This relatively short backtrace is due to the current UI's async field
being set to 1.
Yet another thing to be aware of regarding this problem is the
difference in the way that commands associated to dprintf breakpoints
versus regular breakpoints are handled. While they both use a command
list associated with the breakpoint, regular breakpoints will place
the commands to be run on the bpstat chain constructed in
bp_stop_status(). These commands are run later on. For dprintf
breakpoints, commands are run via the 'after_condition_true' function
pointer directly from bpstat_stop_status(). (The 'commands' field in
the bpstat is cleared in dprintf_after_condition_true(). This
prevents the dprintf commands from being run again later on when other
commands on the bpstat chain are processed.)
Another thing that I noticed is that dprintf breakpoints are the only
type of breakpoint which use 'after_condition_true'. This suggests
that one possible way of fixing this problem, that of making dprintf
breakpoints work more like regular breakpoints, probably won't work.
(I must admit, however, that my understanding of this code isn't
complete enough to say why. I'll trust that whoever implemented it
had a good reason for doing it this way.)
The comment referenced earlier regarding 'executing_breakpoint_commands'
states that the reason for checking this variable is to avoid
potential endless recursion when a 'source' command appears in
bs->commands. We know that a dprintf command is constrained to either
1) execution of a GDB printf command, 2) an inferior function call of
a printf-like function, or 3) execution of an agent-printf command.
Therefore, infinite recursion due to a 'source' command cannot happen
when executing commands upon hitting a dprintf breakpoint.
I chose to fix this problem by having dprintf_after_condition_true()
directly call execute_control_commands(). This means that it no
longer attempts to go through bpstat_do_actions_1() avoiding the
infinite recursion check for potential 'source' commands on the
command chain. I think it simplifies this code a little bit too, a
definite bonus.
Summary:
* breakpoint.c (dprintf_after_condition_true): Don't call
bpstat_do_actions_1(). Call execute_control_commands()
instead.

Subject: gdb-rhbz2022177-dprintf-2.patch
;; Backport test case for dprintf bug (RH BZ 2022177).
Test case for Bug 28308
The purpose of this test is described in the comments in
dprintf-execution-x-script.exp.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28308
The name of this new test was based on that of an existing test,
bp-cmds-execution-x-script.exp. I started off by copying that test,
adding to it, and then rewriting almost all of it. It's different
enough that I decided that listing the copyright year as 2021
was sufficient.

;;scalar values by value
gdb: rework "set debuginfod" commands
As discussed here [1], do some re-work in the "set debuginfod commands".
First, use "set debuginfod enabled on/off/ask" instead of "set
debuginfod on/off/ask". This is more MI-friendly, and it gives an
output that makes more sense in "info set", for example.
Then, make the show commands not call "error" when debuginfod support is
not compiled in. This makes the commands "show" and "show debuginfod"
stop early, breaking gdb.base/default.exp:
Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/default.exp ...
FAIL: gdb.base/default.exp: info set
FAIL: gdb.base/default.exp: show
- Make the "debuginfod enabled" setting default to "off" when debuginfod
support is not compiled in, and "ask" otherwise.
- Make the setter of "debuginfod enabled" error out when debuginfod
support is not compiled in, so that "debuginfod enabled" will always
remain "off" in that case.
- Make the setter of "debuginfod verbose" work in any case. I don't
see the harm in letting the user change that setting, since the user will
hit an error if they try to enable the use of debuginfod.
- I would do the same for the "debuginfod urls" setter, but because
this one needs to see the DEBUGINFOD_URLS_ENV_VAR macro, provided by
libdebuginfod, I made that one error out as well if debuginfod
support is not compiled it (otherwise, I would have left it like
"debuginfod verbose". Alternatively, we could hard-code
"DEBUGINFOD_URLS" in the code (in fact, it was prior to this patch,
but I think it was an oversight, as other spots use
DEBUGINFOD_URLS_ENV_VAR), or use a dummy string to store the setting,
but I don't really see the value in that.
Rename debuginfod_enable to debuginfod_enabled, just so it matches the
setting name.

[PR gdb/27026] CTRL-C is ignored when debug info is downloaded
During debuginfod downloads, ctrl-c should result in the download
being cancelled and skipped. However in some cases, ctrl-c fails to
get delivered to gdb during downloading. This can result in downloads
being unskippable.
Fix this by ensuring that target_terminal::ours is in effect for the
duration of each download.

gdb: add set/show commands for managing debuginfod
Add 'set debuginfod' command. Accepts 'on', 'off' or 'ask' as an
argument. 'on' enables debuginfod for the current session. 'off'
disables debuginfod for the current session. 'ask' will prompt
the user to either enable or disable debuginfod when the next query
is about to be performed:
This GDB supports auto-downloading debuginfo from the following URLs:
<URL1> <URL2> ...
Enable debuginfod for this session? (y or [n]) y
Debuginfod has been enabled.
To make this setting permanent, add 'set debuginfod on' to .gdbinit.
For interactive sessions, 'ask' is the default. For non-interactive
sessions, 'off' is the default.
Add 'show debuginfod status' command. Displays whether debuginfod
is set to 'on', 'off' or 'ask'.
Add 'set/show debuginfod urls' commands. Accepts a string of
space-separated debuginfod server URLs to be queried. The default
value is copied from the DEBUGINFOD_URLS environment variable.
Finally add 'set/show debuginfod verbose' commands to control whether
debuginfod-related output is displayed. Verbose output is enabled
by default.

1) Reference array of structs instead of first member during memcpy
aarch64-tdep.c defines the following macro:
do \
{ \
unsigned int mem_len = LENGTH; \
if (mem_len) \
{ \
MEMS = XNEWVEC (struct aarch64_mem_r, mem_len); \
memcpy(&MEMS->len, &RECORD_BUF[0], \
sizeof(struct aarch64_mem_r) * LENGTH); \
} \
} \
while (0)
This is simlpy allocating a new array and copying it. However, for
the destination address, it is actually copying into the first member
of the first element of the array (`&MEMS->len"). This elicits a
warning with GCC 12:
../../binutils-gdb/gdb/aarch64-tdep.c: In function ‘int aarch64_process_record(gdbarch*, regcache*, CORE_ADDR)’:
../../binutils-gdb/gdb/aarch64-tdep.c:3711:23: error: writing 16 bytes into a region of size 8 [-Werror=stringop-overflow=]
3711 | memcpy(&MEMS->len, &RECORD_BUF[0], \

| ^~~
The simple fix is to reference the array, `MEMS' as the destination of the copy.
Tested by rebuilding.
2) Fix build with current GCC: EL_EXPLICIT(location) always non-NULL
Compiling GDB with current GCC (1b4a63593b) runs into this:
src/gdb/location.c: In function 'int event_location_empty_p(const event_location*)':
src/gdb/location.c:963:38: error: the address of 'event_location::<unnamed union>::explicit_loc' will never be NULL [-Werror=address]

src/gdb/location.c:57:30: note: 'event_location::<unnamed union>::explicit_loc' declared here

GCC is right, EL_EXPLICIT is defined as returning the address of an
union field:
/* An explicit location. */
struct explicit_location explicit_loc;
#define EL_EXPLICIT(P) (&((P)->u.explicit_loc))
and thus must always be non-NULL.

;; Backport fix which fixes internal error due to libcc_s lacking a

Fix GDB internal error by using text (instead of data) section offset
Fedora Rawhide is now using gcc-12.0. As part of updating to the
gcc-12.0 package set, Rawhide is also now using a version of libgcc_s
which lacks a .data section. This causes gdb to fail in the following
fashion while debugging a program (such as gdb) which uses libgcc_s:
(top-gdb) run
Starting program: rawhide-master/bld/gdb/gdb
...
objfiles.h:467: internal-error: sect_index_data not initialized
A problem internal to GDB has been detected,
further debugging may prove unreliable.
...
I snipped the backtrace from the above output. Instead, here's a
portion of a backtrace obtained using GDB's backtrace command.
(Obviously, in order to obtain it, I used a GDB which has been patched
with this commit.)

The function 'relocate_address' in gdb/stap-probe.c attempts to do
its "relocation" by using objfile->data_section_offset(). That
method, data_section_offset() is defined as follows in objfiles.h:
CORE_ADDR data_section_offset () const
{
return section_offsets[SECT_OFF_DATA (this)];
}
The internal error occurs when the SECT_OFF_DATA macro finds that the
'sect_index_data' field is -1:
#define SECT_OFF_DATA(objfile) \
((objfile->sect_index_data == -1) \
? (internal_error (__FILE__, __LINE__, \
_("sect_index_data not initialized")), -1) \
: objfile->sect_index_data)
relocate_address() is obtaining the section offset in order to compute
a relocated address. For some ABIs, such as the System V ABI, the
section offsets will all be the same. So for those ABIs, it doesn't
matter which offset is used. However, other ABIs, such as the FDPIC
ABI, will have different offsets for the various sections. Thus, for
those ABIs, it is vital that this and other relocation code use the
correct offset.
In stap_probe::get_relocated_address, the address to which to add the
offset (thus forming the relocated address) is obtained via
this->get_address (); get_address is a getter for m_address in
probe.h. It's documented/defined as follows (also in probe.h):
/* The address where the probe is inserted, relative to
SECT_OFF_TEXT. */
CORE_ADDR m_address;
(Thanks to Tom Tromey for this observation.)
So, based on this, the current use of data_section_offset /
SECT_OFF_DATA is wrong. This relocation code should have been using
text_section_offset / SECT_OFF_TEXT all along. That being the
case, I've adjusted the stap-probe.c relocation code accordingly.
Searching the sources turned up one other use of data_section_offset,
in gdb/dtrace-probe.c, so I've updated that code as well. The same
reasoning presented above applies to this case too.
Summary:
* gdb/dtrace-probe.c (dtrace_probe::get_relocated_address):
Use method text_section_offset instead of data_section_offset.
* gdb/stap-probe.c (relocate_address): Likewise.

Subject: gdb-rhbz2068280-debuginfod-unavailable-size.patch
;; Backport upstream patch from Aaron Merey which suppresses debuginfod
;; progress messages when size is zero. (RH BZ 2068280).
Remove download size from debuginfod progress messages if unavailable
Currently debuginfod progress update messages include the size of
each download:
Downloading 7.5 MB separate debug info for /lib/libxyz.so.0
This value originates from the Content-Length HTTP header of the
transfer. However this header is not guaranteed to be present for
each download. This can happen when debuginfod servers compress files
on-the-fly at the time of transfer. In this case gdb wrongly prints
"-0.00 MB" as the size.
This patch removes download sizes from progress messages when they are
not available. It also removes usage of the progress bar until
a more thorough reworking of progress updating is implemented. [1]

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 there is a problem with testsuite.unix non-unique subdir name and also
a problem with make -j parallelization of the testsuite.

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

Subject: gdb-test-for-rhbz1976887.patch
;; Backport test for RHBZ 1976887 (Kevin Buettner).
Test case reproducing PR28030 bug
The original reproducer for PR28030 required use of a specific
compiler version - gcc-c++-11.1.1-3.fc34 is mentioned in the PR,
though it seems probable that other gcc versions might also be able to
reproduce the bug as well. This commit introduces a test case which,
using the DWARF assembler, provides a reproducer which is independent
of the compiler version. (Well, it'll work with whatever compilers
the DWARF assembler works with.)
To the best of my knowledge, it's also the first test case which uses
the DWARF assembler to provide debug info for a shared object. That
being the case, I provided more than the usual commentary which should
allow this case to be used as a template when a combo shared
library / DWARF assembler test case is required in the future.
I provide some details regarding the bug in a comment near the
beginning of locexpr-dml.exp.
This problem was difficult to reproduce; I found myself constantly
referring to the backtrace while trying to figure out what (else) I
might be missing while trying to create a reproducer. Below is a
partial backtrace which I include for posterity.

I'll note a few points regarding this backtrace:
Frame #1 is where the internal error occurs. It's caused by an
unhandled case for FIELD_LOC_KIND_DWARF_BLOCK. The fix for this bug
adds support for this case.
Frame #22 - it's a partial backtrace - shows that GDB is attempting to
(re)run the program. You can see the exact command sequence that was
used for reproducing this problem in the PR (at
https://sourceware.org/bugzilla/show_bug.cgi?id=28030), but in a
nutshell, after starting the program and advancing to the appropriate
source line, GDB was asked to step into libstdc++; a "finish" command
was issued, returning a value. The fact that a value was returned is
very important. GDB was then used to step back into libstdc++. A
breakpoint was set on a source line in the library after which a "run"
command was issued.
Frame #19 shows a call to objfile_purge_solibs. It's aptly named.
Frame #7 is a call to the destructor for one of the objfile solibs; it
turned out to be the one for libstdc++.
Frames #6 thru #3 show various value preservation frames. If you look
at preserve_values() in gdb/value.c, the value history is preserved
first, followed by internal variables, followed by values for the
extension languages (python and guile).

+# This test case uses the DWARF assembler to reproduce the problem
+# described by PR28030. The bug turned out to be that
+# FIELD_LOC_KIND_DWARF_BLOCK was not handled when recursively copying
+# a value's type when preserving the value history during the freeing
+# up of objfiles associated with a shared object. (Yes, figuring out
+# how to make this happen in a concise test case turned out to be
+# challenging.)
+#
+# The following elements proved to be necessary for reproducing the
+# problem:
+#
+# 1) A location expression needed to be used with
+# DW_AT_data_member_location rather than a simple offset.
+# Moreover, this location expression needed to use opcodes
+# which GDB's DWARF reader could not convert to a simple
+# offset. (Note, however, that GDB could probably be improved
+# to handle the opcodes chosen for this test; if decode_locdesc()
+# in dwarf2/read.c is ever updated to handle both DW_OP_pick and
+# DW_OP_drop, then this test could end up passing even if
+# the bug it's intended to test has not been fixed.)
+#
+# 2) The debug info containing the above DWARF info needed
+# to be associated with a shared object since the problem
+# occurred while GDB was preserving values during the
+# purging of shared objects.
+#
+# 3) After performing some simple gdb commands, the program is
+# run again. In the course of running the objfile destructor
+# associated with the shared object, values are preserved
+# along with their types. As noted earlier, it was during
+# the recursive type copy that the bug was observed.
+#
+# Therefore, due to #2 above, this test case creates debug info
+# which is then used by a shared object.
