[PATCH] D54175: [PGO] context sensitive PGO

[Rong Xu via Phabricator via llvm-commits]

xur updated this revision to Diff 183899.
xur added a comment.

Fixed a pass ordering issue in legacy pass manager for ThinLTO: Need to place CS Instrumentation after EliminateAvailableExternallyPass. This can cause duplicate profile variables that leads to bad profile for online profile merge.

Also synced the trunk and fixed a merge issue.
