[PATCH] D136829: [SDAG] Fix v1i8 -> 1x i32 handling in getCopyToPartsVector

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/test/CodeGen/AMDGPU/dagcombine-v1i8-extractvecelt-crash.ll:41
+  %load = load <1 x i8>, <1 x i8> addrspace(5)* %addr, align 1
+  store <1 x i8> poison, <1 x i8> addrspace(5)* %addr, align 1
+  store <1 x i8> %load, <1 x i8> addrspace(5)* %addr, align 1
----------------
Is this store of poison really doing anything here?
