Hello all, Is there a way to register callback that runs before/after passes? PassTimingInfo seems to do a similar thing by calling PassInstrumentationCallbacks::registerBeforePassCallback / registerAfterPassCallback, but it is hard-wired with StandardInstrumentations class. Do we have something similar to RegisterStandardPasses, so custom callbacks can be added from somewhere outside LLVM?

I had a chance to try -print-after-all with NPM. It seems like there's still no output for the passes before objc-arc-contract (which is basically what I saw before.) Does anyone else see this? Are we talking about the same thing? *** IR Dump After ObjC ARC contraction *** *** IR Dump After Pre-ISel Intrinsic Lowering *** *** IR Dump After Expand Atomic instructions *** *** IR Dump After

...ese are for dynamic registering machine passes and also used for in-tree machine passes. Personlly I don't think this is needed and similar opinions were expressed before (https://reviews.llvm.org/D54203#1291969). We should probably just register them as normal passes. - Timing machine passes. (StandardInstrumentation handle this already)
