[PATCH] D30603: New Test-Case for Region Analysis

[Nandini Singhal via Phabricator via llvm-commits]

nandini12396 updated this revision to Diff 90602.
nandini12396 added a comment.

Sorry for the delay.

The output of opt -instnamer was the same as before (maybe because the bb names are not tmp?).
