[PATCH] D91673: [PGO] Enable preinline and cleanup when optimize for size

[Rong Xu via Phabricator via llvm-commits]

xur added a comment.

This is probably OK for -Os (SizeLevel == 1), but we need to be careful with Oz (SizeLevel == 2).
We already know that enabling preinliner in general will reduce size -- as the preinliner is pretty conservative. But there will be cases size will be increased.

I would like more test results (like bootstrap clang) before committing.
