[PATCH] D19203: AMDGPU/SI: Add llvm.amdgcn.s.waitcnt.all intrinsic

[Nicolai Hähnle via llvm-commits]

nhaehnle updated this revision to Diff 54311.
nhaehnle added a comment.

Changed the intrinsic to take a single argument.

Also changed the SIInsertWaits logic so that the intrinsic will be delayed
up to the next counter-incrementing instruction or the next "natural" wait
(and then merged with it).
