Description: API documentation for the Rust `__m128` struct in crate `core`.
Keywords: rust, rustlang, rust-lang, __m128

# 1.27.0[−][src]Struct core::arch::x86_64::__m128

    #[repr(simd)]
    pub struct __m128(_, _, _, _);

This is supported on x86-64 only.

128-bit wide set of four `f32` types, x86-specific

This type is the same as the `__m128` type defined by Intel, representing a 128-bit SIMD register which internally is consisted of four packed `f32` instances. Usage of this type typically corresponds to the `sse` and up target features for x86/x86_64.

Note that unlike `__m128i`, the integer version of the 128-bit registers, this `__m128` type has one interpretation. Each instance of `__m128` always corresponds to `f32x4`, or four `f32` types packed together.

Most intrinsics using `__m128` are prefixed with `_mm_` and are suffixed with "ps" (or otherwise contain "ps"). Not to be confused with "pd" which is used for `__m128d`.

# Examples

    #[cfg(target_arch = "x86")]
    use std::arch::x86::*;
    #[cfg(target_arch = "x86_64")]
    use std::arch::x86_64::*;

    let four_zeros = _mm_setzero_ps();
    let four_ones = _mm_set1_ps(1.0);
    let four_floats = _mm_set_ps(1.0, 2.0, 3.0, 4.0);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
