[PATCH] D87047: [clang] Add command line options for the Machine Function Splitter.

[David Li via Phabricator via cfe-commits]

davidxl added a comment.

For x86 target, should it be turned on when -fprofile-use= option is specified unless -fno-split-machine-function is specified?

Also is it worth to give a warning if the option is specified but PGO is not on?
