[PATCH] D76971: Deduce attributes for aligned_alloc in InstCombine

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCalls.cpp:4445
+                      Attribute::getWithDereferenceableOrNullBytes(
+                          Call.getContext(), Op1C->getZExtValue()));
   } else if (isReallocLikeFn(&Call, TLI) && Op1C) {
----------------
When Op0C is set (regardless of Op1C), we can set the alignment attribute on the return value, can't we?
