kstoimenov added a comment.
This change is breaking memory sanitizer in some cases. We observed that when
the argument is not actually removed the pass is dropping the noundef
attribute. See the diff snippet below. Is that an intended behavior?
We would like to revert this as it is breaking MSan tests.
Thanks,
Kirill
