reject aarch64 target feature toggling that would change the float ABI ~~Stacked on top of https://github.com/rust-lang/rust/pull/133099. Only the last two commits are new.~~ The first new commit lays the groundwork for separately controlling whether a feature may be enabled or disabled. The second commit uses that to make it illegal to *disable* the `neon` feature (which is only possible via `-Ctarget-feature`, and so the new check just adds a warning). Enabling the `neon` feature remains allowed on targets that don't disable `neon` or `fp-armv8`, which is all our built-in targets. This way, the entire PR is not a breaking change. Fixes https://github.com/rust-lang/rust/issues/131058 for hardfloat targets (together with https://github.com/rust-lang/rust/pull/133102 which fixed it for softfloat targets). Part of https://github.com/rust-lang/rust/issues/116344. |
