Because this needs to beconverted at runtime, msan injects a LUT (implemented as a vectorwith extractelement).Differential Revision: https://reviews.llvm.org/D83337 List of files: /llvm-project-15.0.7/compiler-rt/test/msan/libatomic.c Wed, 22 Jul 2020 16:34:55 +0000 Gui Andrade <guiand@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/msan/libatomic.c#1f29171a update libatomic instrumentation List of files: /llvm-project-15.0.7/compiler-rt/test/msan/libatomic.c Sat, 18 Jul 2020 03:39:14 +0000 Gui Andrade <guiand@google.com>
