It's produced small bug reports for a number of passes, but the above failures don't get spotted with the clang piped into opt approach. [...] The big question for me, is does this increase the potential coverage?


By default opt doesn't run -codegenprepare in its -OX pipelines, but it does supporting testing it. See e.g https://reviews.llvm.org/D47282.

The -stack-coloring pass lives in a weird space: it's a machine function pass which runs after isel, but it modifies IR. I don't think debugify operates on a very useful level at this point.
