angushewlett added a comment. Having applied this patch to the clang latest (which took a bit of doing, and it's possible I messed up along the way) - all working in general, and a roughly 6x speed-up on my i7-7820X. However, PCH support does not seem to work correctly.
Specifically, it looks like when a file is set to build with /Yc (Create PCH), this is not executed serially with respect to the other jobs. Therefore it attempts to compile targets with /Yu (Use PCH) before the PCH has been generated, and fails. When one or more files are passed with /Yc, PCH generation needs to execute to completion before the other jobs are started. If I compile without using PCHs, it all works correctly (but clearly there's some performance hit). Can anyone confirm if they've got /Yc & /Yu working correctly on their system? Thanks, Angus.
