[PATCH] D32006: Mark invariant.group.barrier as inaccessiblememonly

[Hal Finkel via Phabricator via llvm-commits]

hfinkel added inline comments.


================
Comment at: include/llvm/IR/Intrinsics.td:620
 // because it would cause CSE of two barriers with the same argument.
 // Readonly and argmemonly says that barrier only reads its argument and
 // it can be CSE only if memory didn't change between 2 barriers call,
----------------
You'd need to update the comment.
