[PATCH] D42854: [AMDGPU] Suppress redundant waitcnt instrs

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: lib/Target/AMDGPU/SIInsertWaitcnts.cpp:1533
       // Leaving the previously existing waitcnts is conservatively correct.
-      if (CompilerGeneratedWaitcntSet.find(&Inst) ==
-          CompilerGeneratedWaitcntSet.end())
+      if (TrackedWaitcntSet.find(&Inst) ==
+          TrackedWaitcntSet.end())
----------------
!TrackedWaitcntSet.count(&Inst) I guess.
