[PATCH] D76232: [AMDGPU] Fix whole wavefront mode

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIWholeQuadMode.cpp:538
 
   // Skip instructions that are not affected by EXEC
   if (TII->isScalarUnit(MI))
----------------
Can't this whole function be replaced with SIInstrInfo::mayReadExec?


================
Comment at: llvm/test/CodeGen/AMDGPU/wqm.mir:119-147
+name:            copy_exec
+alignment:       1
+exposesReturnsTwice: false
+legalized:       false
+regBankSelected: false
+selected:        false
+failedISel:      false
----------------
Should be able to remove all of this (except tracksRegLiveness: true)
