Merge commit 4bb2416d42eb from llvm-project (by Jessica Clarke): [builtins][AArch64] Implement _sync out-of-line atomics Whilst Clang does not use these, recent GCC does, and so on systems such as FreeBSD that wish to use compiler-rt as the system runtime library but also wish to support building programs with GCC these interfaces are needed. This is a light adaptation of the code committed to GCC by Sebastian Pop , relicensed with permission for use in compiler-rt.

Build compiler-rt against libunwind, not libcxxrtParts of compiler-rt are also built for libgcc_eh and libgcc_s, andthese were already pointing to the libunwind unwind.h. For the sake ofconsistency, also build compiler-rt itself against the libunwindunwind.h, not the libcxxrt one.MFC after: 3 days List of files: /freebsd-14.2/lib/libcompiler_rt/Makefile

cc55ee80 - compilert-rt: build out-of-line LSE atomics helpers for aarch64

Wed, 28 Jul 2021 20:30:04 +0000

compilert-rt: build out-of-line LSE atomics helpers for aarch64Both clang >= 12 and gcc >= 10.1 now default to -moutline-atomics foraarch64. This requires a bunch of helper functions in libcompiler_rt.a,to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel".(Note: of course you can use -mno-outline-atomics as a workaround too,but this would negate the potential performance benefit of the fasterLSE instructions.)Bump __FreeBSD_version so ports maintainers can easily detect this.PR: 257392MFC after: 2 weeks List of files: /freebsd-14.2/lib/libcompiler_rt/Makefile

Buildit without stack smashing protection (SSP, -fstack-protector) in orderto support building binaries without SSP, especially the dynamic linker.Besides, SSP is probably not very valuable in this library.Reviewed by: arichardson, dim, kibSponsored by: Dell EMC IsilonDifferential Revision: https://reviews.freebsd.org/D27786 List of files: /freebsd-14.2/lib/libcompiler_rt/Makefile

c8b5e3de - Fix llvm-libunwind userspace build on ARM

Tue, 05 Nov 2019 03:20:40 +0000

Fix llvm-libunwind userspace build on ARMGCC's libgcc exports a few ARM-specific symbols for ARM EABI, AEABI, orEHABI or whatever it's called. Export the same ones from LLVM-libunwind'slibgcc_s, on ARM. As part of this, convert libgcc_s from a directVersion.map to one constructed from component Symbol.map files. This allowsthe ARM-specific Symbol.map to be included only on ARM.Fix ARM-only oddities in struct name/aliases in LLVM-libunwind to matchnon-ARM definitions and ARM-specific expectations in libcxxrt /libcompiler_rt.No functional change intended for non-ARM architectures.This commit does not actually flip the switch for ARM defaults from libgccto llvm-libunwind, but makes it possible (to compile, anyway).
