Remove special case for `simd_shuffle` arg promotion#69280

ecstatic-morse · 2020-02-19T05:34:18Z

After rust-lang/stdarch#825, these intrinsics are now defined with #[rustc_args_required_const(2)], so the special-case is no longer necessary.

petrochenkov · 2020-02-19T05:54:10Z

FWIW, we have function parameter attributes now, so #[rustc_args_required_const(N)] on functions could become #[rustc_required_const] on function parameters.
Perhaps we need to open an issue for this.

Ooh, this would be much better. I can open the issue if you like?

Yeah, that would be nice.

Some tests declare their own simd_shuffle platform intrinsic, which now needs the attribute. I assume this is okay (cc @petrochenkov).

…pecial-case, r=petrochenkov Remove special case for `simd_shuffle` arg promotion After rust-lang/stdarch#825, these intrinsics are now defined with `#[rustc_args_required_const(2)]`, so the special-case is no longer necessary.

@petrochenkov

…nkov Revert #69280 Resolves #69313 by reverting #69280. After #69280, `#[rustc_args_required_const(2)]` is required on the declaration of `simd_shuffle` intrinsics. This is allowed breakage, since you can't define platform intrinsics on stable. However, the latest release of the widely used `packed_simd` crate defines these intrinsics without the requisite attribute. Since there's no urgency to merge #69280, let's revert it. We can reconsider when rust-lang/packed_simd#278 is included in a point release of `packed_simd`. r? @petrochenkov

This change was made in `stdarch` but not `packed_simd`. See rust-lang/rust#69280 for background.
