[PATCH] D86360: Add new hidden option -print-changed which only reports changes to IR

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Detecting changes of IR transformations is pain and I am really exited to see `-print-changed`, the diff version `-print-changes` and `-dot-cfg-changed` . Added @fedor.sergeev who is the original implementer of `-print-*` in the new PM.

Can you mark the dependency relation of D87000 <https://reviews.llvm.org/D87000> clearly? Why does D87000 <https://reviews.llvm.org/D87000> delete lots of code added in this patch? If you are organizing patches in a series, please make sure adjacent patches don't cancel each other locally.
