[PATCH] D86657: Add new hidden option -print-crash-IR that prints out IR that caused opt pipeline to crash

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

Ok I guess this makes sense over --print-before-all.

To bikeshed a bit, maybe the option should be named --print-on-crash? For example --print-before-all does not contain "IR" in the name.

It would be nice to include a test. Maybe creating a new pass that crashes upon running could be useful.

Looks like the latest diff on Phab is against the first revision, could that be fixed?
