[PATCH] D136169: [AMDGPU] Avoid SCC clobbering before S_CSELECT_B32

[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIRegisterInfo.cpp:1632
+                 .addImm(-ScratchOffsetRegDelta);
+    I->getOperand(3).setIsDead();
   }
----------------
Do you still need all these setIsDead changes? In any case can you remove them from *this* patch, so it just contains the essential changes? Maybe put them all in a separate patch, if there is still any need for them.
