    Impressive technical work and authorship. My quibble, which seems significant in context, is what happened with AoT?

      AoT uses the same codegen (mostly) as the JIT so if you see a JIT improvement it's possible NativeAOT/ilc picked up that improvement too.

      Unless it's a runtime-only optimization, like guarded devirtualization... there's no straightforward way for an AOT compiler to do that without profiling data.
