This patch exercised an edge case for 32-bit systems in
target_xfer_memory, a function that has been removed in 2006.
The test that patch added has been irrelevant for some time.
Update gdb-6.3-rh-testversion-20041202.patch.
Update gdb-6.3-bz140532-ppc-unwinding-test.patch.
Update gdb-6.6-buildid-locate.patch.
Update gdb-6.6-buildid-locate-rpm.patch.
Remove 'Recommends: ' line for gcc-gdb-plugin for BZ2149246.
Add 'define _lto_cflags ' to avoid ODR violations.
Add -Wno-stringop-overflow to --enable-gdb-build-warnings to work around
gcc problem.
The patch 'gdb-test-ivy-bridge.patch' adds some disassembly tests for
various i386/x86-64 instructions. In fact, the tests added by this
patch are copied directly from gas and should all be covered by
gas/testsuite/gas/i386/i386.exp.
I guess historically, when support for these instructions was first
added, it made sense to have these tests in both GDB and binutils.
But today I think that the testing in binutils is sufficient; if we
really want to validate libopcodes we'd be better off building and
testing gas/binutils as well as GDB.
I propose that we just drop 'gdb-test-ivy-bridge.patch' from the
Fedora GDB tree.
Remove gdb-6.5-readline-long-line-crash-test.patch, this test is now
upstream in commit:
commit bb146a79c7d65e2b578e8c3f652cb118c63741e5

gdb: add test for readline handling very long commands
As this is only a test, I don't see any point in backporting the
upstream commit, we'll pick this up with a later rebase.
Following on from the previous commit, this commit remove
gdb-6.8-bz442765-threaded-exec-test.patch.
Like the previous commit, this patch was a testsuite only patch that
extended the test originally added in the previous commit, in order to
do some additional threads/exec related testing.
The issue exposed by this test (Bug bz442765) was present on Fedora 9,
with GDB 6.8-1.fc9. I have setup a Fedora 9 VM and recreated the
failure with the test in the patch I'm deleting here.
The test does a number of exec's, in each iteration the test binary
runs in a different mode. However, the failure is triggered when we
have a main thread that spawns a worker thread and then called exec
from the main thread.
Just like the previous commit, this situation already exists in the
upstream test gdb.threads/execl.exp, and, if I copy this upstream test
to my Fedora 9 VM, I can reproduce the failure using this upstream
test.
The test being deleted here does do a number of other permutations of
threading and execing, for example it tests calling exec in a
non-threaded inferior, but this is also tested upstream with things
like gdb.base/foll-exec.exp.
In summary, I don't believe there is anything new added by this test
that is not already covered with existing upstream tests, as such, I
think we should drop this patch.
Remove gdb-6.3-bz202689-exec-from-pthread-test.patch. The test
included in this patch is covered by the already upstream test
gdb/testsuite/gdb.threads/execl.exp which was added with this commit:
commit 49fd4a422bb6152043b2b41a1f734694056dbf3b
Date: Thu Jun 5 21:03:59 2008 +0000
Unfortunately, the situation is not as simple as just removing this
patch file. The later patch gdb-6.8-bz442765-threaded-exec-test.patch
builds on the earlier test to cover additional cases.
So, what I've actually done is remove the first patch, but merged the
test entirely into the second patch. I think this is a better
reflection of the current situation; the first patch is
redundant (it's test is already covered upstream), while the second
patch has not yet been reviewed, so it _might_ contain a useful test.
To confirm that the upstream test quoted above actually covers this
test case I did the following:
- Setup a Fedora 3 virtual machine,
- Built the test from the first patch and confirmed that it failed
as described in bug bz202689,
- Copied the upstream execl.exp sources to the virtual machine, and
built the test binary,
- Manually ran the test binary just as the .exp script does, and
confirmed that it failed in the same way as the test from the
original patch.
Remove gdb-6.6-bz230000-power6-disassembly-test.patch as this is now
covered by upstream tests. This patch added some tests of the Power6
disassembler. Disassembler tests are better carried in the gas tree.
Upstream commit:

gas/ppc: Additional tests for DFP instructions
Added some new assembler/disassembler tests to the gas tree that
covered all the instructions that were covered by our local patch.
This upstream commit:
commit 24f3aded1d42f515527e2de7e8e9e26f0b77c932

gdb/testsuite/tui: more testing of the 'focus' command
replaces the tests added in gdb-6.3-focus-cmd-prev-test.patch. As
this patch was only adding a test I see no need to back-port the
upstream commit, we'll pick this up in a later rebase.
- Backport fix for problems associated with GCC 13's self-move warning.
- Tweak gdb-6.6-buildid-locate-rpm.patch so that running GDB's configure
script will not error out due to GCC 13's warnings.
- Backport replace deprecated distutils.sysconfig in python-config.
Fixes RHBZ 2152431, an issue where reading a label symbol's value
would cause GDB to crash. This pulls in two upstream commits
38665d717a3 and c3efaf0afd9 both of which should be in GDB 13 when it
is released.
Changes in this commit:
- Remove gdb-bz601887-dwarf4-rh-test.patch
This adds a very simple test to check whether DWARF4
is implemented. GDB has been using DWARF4 for several
years, and the testsuite coverage supercedes this patch.
- Remove gdb-6.6-buildid-locate-rpm-scl.patch
This patch is applicable only on RHEL6 where .gdb_index
version 5 is used. In recent GDBs, i.e., all DTS releases,
this version could only be read with the option
"use-deprecated-index-sections". RHEL7+ use .gdb_index version 8.
Since RHEL6 is no longer supported, this is unnecessary.
Also remove GDB_INDEX_VERIFY_VENDOR references/code from
gdb-6.6-buildid-locate.patch and gdb.spec
Remove the 'gdb-fortran-frame-string.patch' patch from Fedora GDB. I
have pushed an upstream test that covers everything that this test
covered, see upstream GDB commit:
commit 1c01b23603766fbca4ed4dd12fdd710860e6038e
Date: Fri Nov 4 14:51:11 2022 +0000
gdb/fortran/testsuite: print values and types of string variables
As this is just a testsuite patch, I'm not going to backport this to
Fedora GDB, but when we next rebase, we will pick up this test.
- gdb-physname-pr11734-test.patch
- gdb-physname-pr12273-test.patch
These two tests were merged upstream under a different file name.
- gdb-runtest-pie-override.patch
This patch appears unnecessary today. I have tested on all supported
host architectures and detected no regressions. I presume this was
fixed in a different manner through the years.
- gdb-test-expr-cumulative-archer.patch
The patch contains two tests. Both are upstream already.
While one is a little more involved than what landed upstream,
both tests are equivalent. The other test, gdb.cp/namespace-no-imports.exp,
is identical to upstream's gdb.cp/nsnoimports.exp with whitespace
and other trivial changes.
The test added by this patch from 2005 is a tweaked verion of the upstream
test gdb.threads/watchthreads.exp from 2004. (The current version of
gdb.threads/watchthreads.exp has changed somewhat since 2004.)
The tweaks added to the circa 2004 upstream test consist of setting
a breakpoint on thread_function and then continuing to it. At
that point, initial / runtime values of args[2] and args[3] are
fetched and saved in some TCL variables (which are renamed versions
of args_0 and args_1 in watchthreads.exp). The rest of the changes
to the tweaked script are mostly related to the renaming related to
args_0 and args_1. The other major difference is that watchthreads.exp
places hardware watchpoints on args[0] and args[1] whereas the
tweaked test instead watches args[2] and args[3]. However, all
of these initialized to 0. In the tweaked test, fetching the
initial values when the thread function is first hit should result
in zero values being fetched for args[2] and args[3].
So, in conclusion, the tweaked version of the test doesn't actually
test anything new. I took a look at old posts / threads from the
gdb-patches mailing list, but I couldn't find a post where Jeff
Johnston included this patch (and an explanation of what it does over
the other patch.)
Since this test doesn't offer anything new/better over what's already
upstream, I'm deleting it.
