[PATCH] D70157: Align branches within 32-Byte boundary

[Kan Shengchen via Phabricator via llvm-commits]

skan updated this revision to Diff 230617.
skan added a comment.

Speed up if we only want to simply emit NOPs before branches as needed.  In this condition, BranchPrefix won't be inserted, which reduces the compile time.
