* nptl: Fix cleanups for stack grows up [BZ# 28899]John David Anglin2022-02-281-1/+1
| | | | | | | | _STACK_GROWS_DOWN is defined to 0 when the stack grows up. The code in unwind.c used `#ifdef _STACK_GROWS_DOWN' to selct the stack grows down define for FRAME_LEFT. As a result, the _STACK_GROWS_DOWN define was always selected and cleanups were incorrectly sequenced when the stack grows up.

I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah.

* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Move __pthread_unwind_next into libcFlorian Weimer2021-04-211-4/+9
| | | | | | | | | | | | | | | | | | | It's necessary to stub out __libc_disable_asynccancel and __libc_enable_asynccancel via rtld-stubbed-symbols because the new direct references to the unwinder result in symbol conflicts when the rtld exception handling from libc is linked in during the construction of librtld.map. unwind-forcedunwind.c is merged into unwind-resume.c. libc now needs the functions that were previously only used in libpthread. The GLIBC_PRIVATE exports of __libc_longjmp and __libc_siglongjmp are no longer needed, so switch them to hidden symbols. The symbol __pthread_unwind_next has been moved using scripts/move-symbol-to-libc.py. Reviewed-by: Adhemerva Zanella <adhemerval.zanella@linaro.org>

* Disable spurious -Wstringop-overflow for setjmp/longjmp (bug 26647)Joseph Myers2020-10-301-0/+10
| | | | | | | | | | | | | | | | | Building glibc with GCC 11 fails with (among other warnings) spurious -Wstringop-overflow warnings from calls to setjmp and longjmp with a pointer to a pthread_unwind_buf that is smaller than jmp_buf. As discussed in bug 26647, the warning in libc-start.c is a false positive, because setjmp and longjmp do not access anything (the signal mask) beyond the common prefix of the two structures, so this patch disables the warning for that call to setjmp, as well as for two calls in NPTL code that produce the same warning and look like false positives for the same reason. Tested with build-many-glibcs.py for arm-linux-gnueabi, where this allows the build to get further. Reviewed-by: DJ Delorie <dj@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/nptl/configure.ac tests for forced unwind support and the C cleanup attribute, giving errors if either is unsupported. It does nothing beyond running those two tests. Both the attribute, and _Unwind_GetCFA which is used in the forced unwind test, were added in GCC 3.3. Thus these tests are long obsolete, and this patch removes the configure fragment running them, along with associated conditionals.
