I've built some tests in WebRTC with and without this change. With this change number of __tsan_read/write calls is reduced by 20-40%, binary size decreases by 5-10% and execution time drops by ~5%. For example: $ ls -l old/modules_unittests new/modules_unittests -rwxr-x--- 1 dvyukov 41708976 Jan 20 18:35 old/modules_unittests -rwxr-x--- 1 dvyukov 38294008 Jan 20 18:29 new/modules_unittests $ objdump -d old/modules_unittests | egrep "callq.*__tsan_(read|write|unaligned)" | wc -l 239871 $ objdump -d new/modules_unittests | egrep "callq.*__tsan_(read|write|unaligned)" | wc -l 148365 http://reviews.llvm.org/D7069 llvm-svn: 228917 |
