Is there any way this could be structured that way too? As-is, the layering looks pretty unusual. (And your reland had to teach clang about tablegen targets for that reason.)
Thanks for the feedback.

I can think of two possible solutions:

1. Move the RISCV-only part of `llvm/lib/TargetParser` into `llvm/lib/Target`
2. Move the whole TargetParser inside Target

However, I am not really sure if these are less unusual than the current state of things (or even technically possible).

 I am open for suggestions, and even more open to review a solution that fixes the unusual layering ;).
