* nptl: Move __pthread_unwind_next into libcFlorian Weimer2021-04-211-20/+0
| | | | | | | | | | | | | | | | | | | 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>

* Implement _Unwind_Resume in libc on top of <unwind-link.h>Florian Weimer2021-03-011-2/+46
| | | | | | | | Temporarily move the arm _Unwind_Resume implementation to the file used by libpthread. It will be ported to <unwind-link.h> along with the rest of nptl. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
