[PATCH] D115965: [DSE] Fix a case of invalid dead store elimination

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/DeadStoreElimination.cpp:1215
+      if (auto *I = dyn_cast<Instruction>(Ptr))
+        return I->getParent()->isEntryBlock();
       return true;
----------------
The code structure in this function no longer makes sense. Please rewrite the whole function to first strip offsets / GEP and then do a single entry block check.
