[PATCH] D17864: [PGO] Promote indirect calls to conditional direct calls with value-profile

[Rong Xu via llvm-commits]

xur updated this revision to Diff 54915.
xur added a comment.

Addressed some of the David's most recently comments:
(1) comments change
(2) inline fixupInvokeInst into promote(). After this change, we no longer need the direct-call instruction. So I changed createDirectCallInst() to return the new instruction (either is direct-call or the result-cast). 
(3) simplify the test case for the covariant return for call. 
(4) add a test case for covariant return for invoke.
