[PATCH] D137201: [AggressiveInstCombine] Handle the insert point of the merged load correctly.

[Dave Green via Phabricator via llvm-commits]

dmgreen added inline comments.


================
Comment at: llvm/lib/Transforms/AggressiveInstCombine/AggressiveInstCombine.cpp:828
+  Instruction *Inst = dyn_cast<Instruction>(LI1->getPointerOperand());
+  if (Inst && Inst->getParent() != LI1->getParent())
+    return false;
----------------
If the pointer operand isn't in the same block, is that a problem? If they are in different blocks, and we know all the loads are in the same block, then we know the pointer operand dominates the RootInsert I think. It wont need the moveBefore below.
