reject unsound toggling of RISCV target features ~~Stacked on top of https://github.com/rust-lang/rust/pull/133417, only the last commit is new.~~ Works towards https://github.com/rust-lang/rust/issues/132618 (but more [remains to be done](https://github.com/rust-lang/rust/pull/134337#issuecomment-2544228958)) Part of https://github.com/rust-lang/rust/issues/116344 Cc ``@beetrees`` I hope I got everything. I didn't do anything about "The f and zfinx features are incompatible" and that's not an ABI thing (right?) and I am not sure how to handle it with these ABI checks. r? ``@workingjubilee`` Ideally we'd also reject target specs that disable the `f` feature but set an ABI that requires `f`... but I don't want to duplicate this logic. I have some ideas for how maybe the entire float ABI check logic should be different, now that we have some examples of what these ABI checks look like, but that will be a future PR. |
