[PATCH] D104060: Machine IR Profile

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

Very interesting work.  A high level question, the CSFDO/CSPGO instruments the program after the inlining pass, so it can provide the same level of coverage for machine IR. What additional information do we expect from MIR profile that is not available in CSFDO?
