874e27b5 - Build compiler-rt against libunwind, not libcxxrt

Wed, 09 Mar 2022 21:23:35 +0000

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.Approved by: re (gjb)MFC after: 3 days(cherry picked from commit 7ecd99fa424df001028c5cddc52d25b29232f1af)(cherry picked from commit 4c622a8f051d8dd9fab0719b00a6eccdbd13ac62) List of files: /freebsd-13.1/lib/libcompiler_rt/Makefile

So adding the inline keywords in for __open in ifstream and ofstream. That will also make it consistent with __open in basic_filebuf (it seems we added `inline` there before for gcc build as well).

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).
