[PATCH] D147954: [SimplifyCFG] Merge branch_weights for direct callsites and introduce options to preserve value profile for indirect callsites

[Mingming Liu via Phabricator via llvm-commits]

mingmingl updated this revision to Diff 514766.
mingmingl retitled this revision from "[SimplifyCFG]Prevent premature simplification of indirect callsites with profile data" to "[SimplifyCFG] Merge branch_weights for direct callsites and introduce options to preserve value profile for indirect callsites".
mingmingl edited the summary of this revision.
mingmingl added a comment.

implemented branch_weight merge for direct callsites in hoist and sink, and get rid of the command line option to override indirect-call specific option -> SimplifyCFG option parser still parses it for testing purposes.
