--- Comment #31 from commit-h...@freebsd.org --- A commit references this bug: Author: dim Date: Tue Sep 8 20:28:40 UTC 2020 New revision: 365472 URL: https://svnweb.freebsd.org/changeset/base/365472 Log: Revert r365471 as it is breaking with old gcc on various arches: MFC r364753: Add atomic and bswap functions to libcompiler_rt There have been several mentions on our mailing lists about missing atomic functions in our system libraries (e.g. __atomic_load_8 and friends), and recently I saw __bswapdi2 and __bswapsi2 mentioned too. To address this, add implementations for the functions from compiler-rt to the system compiler support libraries, e.g. libcompiler_rt.a and and libgcc_s.so. This also needs a small fixup in compiler-rt's atomic.c, to ensure that 32-bit mips can build correctly. Bump __FreeBSD_version to make it easier for port maintainers to detect when these functions were added. PR: 230888 Differential Revision: https://reviews.freebsd.org/D26159 MFC r364782: After r364753, there should be no need to suppress -Watomic-alignment warnings anymore for compiler-rt's atomic.c. This occurred because the IS_LOCK_FREE_8 macro was not correctly defined to 0 for mips, and this caused the compiler to emit a runtime call to __atomic_is_lock_free(), and that triggers the warning.
