;; Better parse 64-bit PPC system call prologues.
;;=push: Write new testcase.
2004-06-22 Andrew Cagney <cagney@gnu.org>
* rs6000-tdep.c (struct rs6000_framedata): Add field "func_start".
(skip_prologue): Delete local variable "orig_pc", use
"func_start". Add local variable "num_skip_linux_syscall_insn",
use to skip over first half of a GNU/Linux syscall and update
"func_start".

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.
(i386_linux_sync_debug_registers_across_threads): Ditto.
(i386_linux_insert_watchpoint, i386_linux_remove_watchpoint): Ditto.
(i386_linux_hw_breakpoint, i386_linux_remove_hw_breakpoint): Ditto.
(i386_linux_new_thread): Ditto.
(_initialize_i386_linux_nat): Ditto.
* amd64-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.
(amd64_linux_set_debug_regs_for_thread): New function.
(amd64_linux_sync_debug_registers_callback): Ditto.
(amd64_linux_sync_debug_registers_across_threads): Ditto.
(amd64_linux_insert_watchpoint, amd64_linux_remove_watchpoint): Ditto.
(amd64_linux_hw_breakpoint, amd64_linux_remove_hw_breakpoint): Ditto.
(amd64_linux_new_thread): Ditto.
(_initialize_amd64_linux_nat): Register linux new thread observer.
* testsuite/gdb.threads/watchthreads-threaded.c: New test case.
* 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
testcase of the same name. ]
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.

+ * * Spinning
+ * * Spinning inside a signal handler
+ * * Spinning inside a signal handler executing on the altstack
+ * * 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.
+ *
+ * These are the things threads in JRockit tend to be doing. If gdb

;; Fix TLS symbols resolving for shared libraries with a relative pathname.

;;=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'.

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,

;; 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).

;; Print reasons for failed attach/spawn incl. SELinux deny_ptrace (BZ 786878).
;;=push+jan
http://sourceware.org/ml/gdb-patches/2012-03/msg00171.html
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,
Jan

;; Never kill PID on: gdb exec PID (Jan Kratochvil, RH BZ 1219747).
;;=push+jan
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
2179 if (have_inferiors ())
2180 {
2181 if (!from_tty
2182 || !have_live_inferiors ()
2183 || query (_("A program is being debugged already. Kill it? ")))
2184 iterate_over_inferiors (dispose_inferior, NULL);
2185 else
2186 error (_("Program not killed."));
2187 }
1084 catch_command_errors (core_file_command, pid_or_core_arg,
1085 !batch_flag);
No regressions on {x86_64,x86_64-m32,i686}-fedora24pre-linux-gnu.

Jan

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.

;;=push+jan: Inferior objects should be read in parts, then this patch gets obsoleted.
http://sourceware.org/ml/gdb-patches/2010-06/msg00005.html
Hi,
unfortunately I see this problem reproducible only with the
archer-jankratochvil-vla branch (VLA = Variable Length Arrays - char[var]).
OTOH this branch I hopefully submit in some form for FSF GDB later.
In this case (a general problem but tested for example on Fedora 13 i686):
int
main (int argc, char **argv)
{
char a[argc];
return a[0];
}
(gdb) start
(gdb) print a
../../gdb/utils.c:1251: internal-error: virtual memory exhausted: can't allocate 4294951689 bytes.
It is apparently because boundary for the variable `a' is not initialized
there. Users notice it due to Eclipse-CDT trying to automatically display all
the local variables on each step.
Apparentl no regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu.
But is anone aware of the reasons to use internal_error there?
I find simple error as a perfectly reasonable there.
(history only tracks it since the initial import)
IIRC this idea has been discussed with Tom Tromey, not sure of its origin.
I understand it may be offtopic for FSF GDB but from some GDB crashes I am not
sure if it can happen only due to the VLA variables.
Thanks,
Jan

;; 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

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

From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
From: Andrew Burgess <aburgess@redhat.com>
Date: Sat, 25 Nov 2023 10:35:37 +0000
Subject: gdb-rhbz-2232086-cpp-ify-mapped-symtab.patch
;; Back-port upstream commit acc117b57f7 as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb: C++-ify mapped_symtab from dwarf2/index-write.c
Make static the functions add_index_entry, find_slot, and hash_expand,
member functions of the mapped_symtab class.
Fold an additional snippet of code from write_gdbindex into
mapped_symtab::minimize, this code relates to minimisation, so this
seems like a good home for it.
Make the n_elements, data, and m_string_obstack member variables of
mapped_symtab private. Provide a new obstack() member function to
provide access to the obstack when needed, and also add member
functions begin(), end(), cbegin(), and cend() so that the
mapped_symtab class can be treated like a contained and iterated
over.
I've also taken this opportunity to split out the logic for whether
the hash table (m_data) needs expanding, this is the new function
hash_needs_expanding. This will be useful in a later commit.
There should be no user visible changes after this commit.

Subject: gdb-rhbz-2232086-generate-dwarf-5-index-consistently.patch
;; Back-port upstream commit 3644f41dc80 as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb: generate dwarf-5 index identically as worker-thread count changes
Similar to the previous commit, this commit ensures that the dwarf-5
index files are generated identically as the number of worker-threads
changes.
Building the dwarf-5 index makes use of a closed hash table, the
bucket_hash local within debug_names::build(). Entries are added to
bucket_hash from m_name_to_value_set, which, in turn, is populated
by calls to debug_names::insert() in write_debug_names. The insert
calls are ordered based on the entries within the cooked_index, and
the ordering within cooked_index depends on the number of worker
threads that GDB is using.
My proposal is to sort each chain within the bucket_hash closed hash
table prior to using this to build the dwarf-5 index.
The buckets within bucket_hash will always have the same ordering (for
a given GDB build with a given executable), and by sorting the chains
within each bucket, we can be sure that GDB will see each entry in a
deterministic order.
I've extended the index creation test to cover this case.

;; Back-port upstream commit aff250145af as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb: generate gdb-index identically regardless of work thread count
It was observed that changing the number of worker threads that GDB
uses (maintenance set worker-threads NUM) would have an impact on the
layout of the generated gdb-index.
The cause seems to be how the CU are distributed between threads, and
then symbols that appear in multiple CU can be encountered earlier or
later depending on whether a particular CU moves between threads.
I certainly found this behaviour was reproducible when generating an
index for GDB itself, like:
gdb -q -nx -nh -batch \
-eiex 'maint set worker-threads NUM' \
-ex 'save gdb-index /tmp/'
And then setting different values for NUM will change the generated
index.
Now, the question is: does this matter?
I would like to suggest that yes, this does matter. At Red Hat we
generate a gdb-index as part of the build process, and we would
ideally like to have reproducible builds: for the same source,
compiled with the same tool-chain, we should get the exact same output
binary. And we do .... except for the index.
Now we could simply force GDB to only use a single worker thread when
we build the index, but, I don't think the idea of reproducible builds
is that strange, so I think we should ensure that our generated
indexes are always reproducible.
To achieve this, I propose that we add an extra step when building the
gdb-index file. After constructing the initial symbol hash table
contents, we will pull all the symbols out of the hash, sort them,
then re-insert them in sorted order. This will ensure that the
structure of the generated hash will remain consistent (given the same
set of symbols).
I've extended the existing index-file test to check that the generated
index doesn't change if we adjust the number of worker threads used.
Given that this test is already rather slow, I've only made one change
to the worker-thread count. Maybe this test should be changed to use
a smaller binary, which is quicker to load, and for which we could
then try many different worker thread counts.

gdb: reduce size of generated gdb-index file
I noticed in passing that out algorithm for generating the gdb-index
file is incorrect. When building the hash table in add_index_entry we
count every incoming entry rehash when the number of entries gets too
large. However, some of the incoming entries will be duplicates,
which don't actually result in new items being added to the hash
table.
As a result, we grow the gdb-index hash table far too often.
With an unmodified GDB, generating a gdb-index for GDB, I see a file
size of 90M, with a hash usage (in the generated index file) of just
2.6%.
With a patched GDB, generating a gdb-index for the _same_ GDB binary,
I now see a gdb-index file size of 30M, with a hash usage of 41.9%.
This is a 67% reduction in gdb-index file size.
Obviously, not every gdb-index file is going to see such big savings,
however, the larger a program, and the more symbols that are
duplicated between compilation units, the more GDB would over count,
and so, over-grow the index.
The gdb-index hash table we create has a minimum size of 1024, and
then we grow the hash when it is 75% full, doubling the hash table at
that time. Given this, then we expect that either:
a. The hash table is size 1024, and less than 75% full, or
b. The hash table is between 37.5% and 75% full.
I've include a test that checks some of these constraints -- I've not
bothered to check the upper limit, and over full hash table isn't
really a problem here, but if the fill percentage is less than 37.5%
then this indicates that we've done something wrong (obviously, I also
check for the 1024 minimum size).

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.

Author: Pedro Franco de Carvalho <pedromfc@linux.ibm.com>

Use get_remote_packet_size in download_tracepoint
This patch changes the remote target to use the remote packet size to
build QTDP packets, and to check if there is enough room for the
packet.
I changed the function to raise an error if the packet is too small,
instead of aborting gdb (through xsnprintf). It isn't clear if gdb
will be in a consistent state with respect to the stub after this,
since it's possible that some packets will be sent but not others, and
there could be an incomplete tracepoint on the stub.
The char array used to build the packets is changed to a
gdb::char_vector and sized with the result from
get_remote_packet_size.
When checking if the buffer is large enough to hold the tracepoint
condition agent expression, the length of the expression is multiplied
by two, since it is encoded with two hex digits per expression
byte. For simplicity, I assume that the result won't overflow, which
can happen for very long condition expressions.
gdb/ChangeLog:
2018-08-06 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* remote.c (remote_target::download_tracepoint): Remove BUF_SIZE.
Replace array buf with gdb::char_vector buf, of size
get_remote_packet_size (). Replace references to buf and
BUF_SIZE to buf.data () and buf.size (). Replace strcpy, strcat
and xsnprintf with snprintf. Raise errors if the buffer is too
small.

Author: Pedro Franco de Carvalho <pedromfc@linux.ibm.com>

Use remote register numbers in tracepoint mask
Currently, tracepoint register masks in the QTDP packets include both
internal and remote register numbers, as well as pseudo-register
numbers.
This patch changes this so that the mask only includes remote register
numbers.
Register numbers from agent expressions are already set in the mask
using remote numbers. Other tracepoint actions used internal numbers,
e.g. "collect $regs" or "collect $<pseudoreg>". To handle pseudoreg
numbers, an empty agent expression is created and ax_reg_mask is
called for this expression and the pseudoreg. This will cause the ax
to set its mask with the corresponding remote raw register
numbers (using ax_regs_mask, which calls
gdbarch_ax_pseudo_register_collect).
If ax_regs_mask and gdbarch_ax_pseudo_register_collect also generate
more ax bytecode, the ax is also appended to the collection list. It
isn't clear that this was the original intent for
gdbarch_ax_pseudo_register_collect, and none of the arches seem to do
this, but if this changes in the future, it should work.
The patch also refactors the code used by validate_action line to
validate axs into a function that is now called from every place that
generates axs. Previously, some parts of tracepoint.c that generated
axs didn't check if the ax length was greater than MAX_AGENT_EXPR_LEN.

Variable size for regs mask in collection list
This patch changes collection_list to allow larger register masks.
The mask is changed from an array to a vector and is initialized to
hold the maximum possible remote register number. The stringify
method is updated to resize temp_buf if needed.

stringify the register mask. Use pack_hex_byte for the register
mask.

Allow larger regblock sizes when saving tracefiles
The tracefile.c:trace_save function assumes trace_regblock_size won't
be larger than the MAX_TRACE_UPLOAD constant, used to size the buffer
which holds trace data. This can cause buffer overruns when this is
not the case. This patch changes this function so that the larger
size is used to size the buffer.
