Tagging subscribers to this area: @JulieLeeMSFT, @jakobbotsch Issue DetailsIn JIT we have a debug-only mode where we can run some optimization phases multiple times. It feels to me that we can enable it for NativeAOT even in Release. And I have a feeling that it should bring some nice diffs (probably needs jit-utils for proper diffs) - let's see what CI thinks about it. E.g in #70907 I've got nice diffs by simply running optRedundantBranches twice.

Ah, optRepeat seems to be broken - a lot of various asserts, but I still think it's worth a try someday |
