[PATCH] D96979: [DSE] Extending IsGuaranteedLoopInvariant to support a GetElementPtrInst defined in the entry block

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/DeadStoreElimination.cpp:1922
     if (auto *GEP = dyn_cast<GEPOperator>(Ptr)) {
+      if (IsEntryBlockGEP(GEP))
+        return true;
----------------
this is not really GEP specific right? Any instruction in the entry block should be loop invariant.
