[PATCH] D89386: [AMDGPU] Fix access beyond the end of the basic block in execMayBeModifiedBeforeAnyUse.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstrInfo.cpp:7108
 
-  for (auto &UseInst : MRI.use_nodbg_instructions(VReg)) {
+  for (auto &Use : MRI.use_nodbg_operands(VReg)) {
+    auto &UseInst = *Use.getParent();
----------------
Why change to the uses instead of instructions?
