[PATCH] D152706: [AMDGPU] Use SSAUpdater in PromoteAlloca

[Pierre van Houtryve via Phabricator via llvm-commits]

Pierre-vh added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUPromoteAlloca.cpp:610
+      // Alloca already accessed as vector.
       if (Ptr == &Alloca && DL->getTypeStoreSize(Alloca.getAllocatedType()) ==
+                                DL->getTypeStoreSize(AccessTy)) {
----------------
This will crash if we load/store a value at an offset, and the access type is the same size as the alloca.
Should we check that the index is zero as well here?
