[PATCH] D76954: LLVM support for BB-cluster sections

[Rahman Lavaee via Phabricator via llvm-commits]

rahmanl updated this revision to Diff 253992.
rahmanl added a comment.

Major changes with this update:

  1- Using a StringMap of vectors instead of nested map in getBBClusterInfo (BBSectionsPrepare.cpp).
  2- Structured error handling in getBBClusterInfo.
  3- New basicblock-section-clusters tests exercising various combinations of clustering (involving exception handling blocks and cold code), add ensuring that branches are optimized/inserted at the right places.
