[PATCH] D31161: [AMDGPU] New Waitcnt Insertion Pass

[Kannan Narayanan via Phabricator via llvm-commits]

kanarayan updated this revision to Diff 93059.
kanarayan added a comment.

1. Rename SI_RETURN to SI_RETURN_TO_EPILOG to reflect recent change.
2. Condition the nop insertion to break soft clauses on isXNACKEnabled(). Add a note to also condition this code on hasSoftClauses when that code is put back.
3. Fix tests added since last patch to reflect the new pass.
4. Remove experimental code.
