[PATCH] D121437: [AMDGPU] Add s_nop WaitStates between neighboring mfma

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/GCNHazardRecognizer.cpp:1397
 
     if (WaitStatesNeeded == MaxWaitStates)
       return WaitStatesNeeded; // Early exit.
----------------
Longest MAI is 64 cycles. You may want to move your code to the top as it can bring longest nop sequence.
