Prototype using const generic for simd_shuffle IDX array cc https://github.com/rust-lang/rust/issues/85229 r? `@workingjubilee` on the design TLDR: there is now a `fn simd_shuffle_generic<T, U, const IDX: &'static [u32]>(x: T, y: T) -> U;` intrinsic that allows replacing ```rust simd_shuffle(a, b, const { stuff }) ``` with ```rust simd_shuffle_generic::<_, _, {&stuff}>(a, b) ``` which makes the compiler implementations much simpler, if we manage to at some point eliminate `simd_shuffle`. There are some issues with this today though (can't do math without bubbling it up in the generic arguments). With this change, we can start porting the simple cases and get better data on the others. |
