[PATCH] D77082: [AMDGPU] Handle SMRD signed offset immediate

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUISelDAGToDAG.cpp:1798
 
-  if (Gen == AMDGPUSubtarget::SEA_ISLANDS) {
-    EncodedOffset =
-        AMDGPU::getSMRDEncodedLiteralOffset32(*Subtarget, ByteOffset);
-    if (EncodedOffset) {
-      Offset = CurDAG->getTargetConstant(*EncodedOffset, SL, MVT::i32);
-      return true;
-    }
+  if (!CurDAG->SignBitIsZero(ByteOffsetNode))
+    return false;
----------------
The GlobalISel patch seems to be missing this part?
