[PATCH] D158602: [AMDGPU] Don't wait for counters in chain function prologues

[Ruiling, Song via Phabricator via llvm-commits]

ruiling added a comment.

I don't quite understand the change, now that the counters are in unknown state, shouldn't we wait for their arrival so that we can access the registers for the arguments (which may be loaded from memory in the caller)? I think we definitely need these waits at the entry of cs_chain* function.
