--- Comment #2 from Andrew Trick <atrick at apple.com> ---
The test case in this bug report is fixed by
http://reviews.llvm.org/rL256728.

I'm closing this because I don't have a test case and I no longer think it
makes much sense to mark may-unwind calls "readonly". An unwind path always
touches some memory. That fact that it doesn't alias with LLVM-visible memory
access can be handled by alias analysis.
