Wrong return type for _mm_extract_ps?

[jsgf]

std::arch::x86_64::_mm_extract_ps (and x86) is documented as

Extract a single-precision (32-bit) floating-point element from a, selected with imm8

but has the signature

pub unsafe fn _mm_extract_ps(a: __m128, imm8: i32) -> i32

Shouldn't this be returning f32? The implementation just uses mem::transmute with inferred types, so its just transmuting the result to i32 even though the implementation is using simd_transmute to make an f32.

Is this a bug or am I missing something here?

Relevant context, which also applies to Rust: https://stackoverflow.com/questions/5526658/intel-sse-why-does-mm-extract-ps-return-int-instead-of-float

OK, maybe its worth having something in the documentation about this then.
