There was a problem hiding this comment.
You mentioned that discriminant for Generators became u32. Can you elaborate "how" (in e.g. the commit message), given that the changes otherwise only involve removing the previously present i32… default.
Otheriwse r=me on implementation...

This now reuses `fn discriminant_ty` in project, removing some code duplication. Doing so made me realize that we previously had a disagreement about the discriminant type of generators, with MIR using `u32` and codegen and trait selection using `i32`. We now always use `u32`.
