From 1d95b035c721908d3bcbbca9e8d3a5e55a24c09e Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Wed, 21 Apr 2021 19:49:50 +0200 Subject: nptl: Move __pthread_unwind_next into libc 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.
