From FEDORA_PATCHES Mon Sep 17 00:00:00 2001

Date: Fri, 27 Oct 2017 21:07:50 +0200
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.
2008-02-27 Jan Kratochvil <jan.kratochvil@redhat.com>

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.

;; non-deterministic gdb-index generation (RH BZ 2232086).
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).

;; 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.

Subject: gdb-rhbz2232086-refactor-selftest-support.patch
;; Back-port upstream commit 1f0fab7ff86 as part of a fix for
;; non-deterministic gdb-index generation (RH BZ 2232086).
gdb/testsuite: small refactor in selftest-support.exp
Split out the code that makes a copy of the GDB executable ready for
self testing into a new proc. A later commit in this series wants to
load the GDB executable into GDB (for creating an on-disk debug
index), but doesn't need to make use of the full do_self_tests proc.
There should be no changes in what is tested after this commit.

From f27cc602d85c46b46f5b02d6f584a1d872e098e3 Mon Sep 17 00:00:00 2001
From: Tom Tromey <tom@tromey.com>

Subject: [PATCH] Make pascal_language::print_type handle varstring==nullptr
PR gdb/31524 points out a crash when pascal_language::print_type is
called with varstring==nullptr. This crash is a regression arising
from the printf/pager rewrite -- that indirectly removed a NULL check
from gdb's "puts".
This patch instead fixes the problem by adding a check to print_type.
Passing nullptr here seems to be expected in other places (e.g., there
is a call to type_print like this in expprint.c), and other
implementations of this method (or related helpers) explicitly check
for NULL.
I didn't write a test case for this because it seemed like overkill
for a Pascal bug that only occurs with -i=mi. However, if you want
one, let me know and I will do it.
