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

[Jamie Schmeiser via Phabricator via llvm-commits]

jamieschmeiser updated this revision to Diff 376887.
jamieschmeiser retitled this revision from "Add new hidden option -print-crash-IR that prints out IR that caused opt pipeline to crash" to "Add new hidden option -print-on-crash that prints out IR that caused opt pipeline to crash".
jamieschmeiser added a comment.

Added the usual filtering options (filter-passes and filter-print-func) with uninteresting passes being saved with a message that they were filtered out.  This should speed up things significantly when they are used.  If the user isn't aware of the name of the crashing pass, they can use -filter-passes=blah (where blah doesn't exist) and they will get a message saying that the pass was filtered out.  They can discover the name from that message and then rerun it with -filter-passes.
