This is a tracking issue for the RFC "SIMD vectors in FFI" (rust-lang/rfcs#2574).
The feature gate is #![feature(simd_ffi)].

Steps:

Unresolved questions:

  • Should it be possible to use, e.g., __m128 on C FFI when the avx feature is enabled? Does that change the calling convention and make doing so unsafe ? We could extend this RFC to also require that to use certain types certain features must be disabled.
