[PATCH] D112464: [x86] limit vector increment fold to allow load folding

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelDAGToDAG.cpp:900
+    auto mayPreventLoadFold = [&]() {
+      return N->getOperand(0).getOpcode() == ISD::LOAD &&
+             N->getOpcode() == ISD::ADD && Subtarget->hasAVX() &&
----------------
What about multi-use load, we usually don't load-fold those?
