# Struct core::arch::x86_64::__m128d
1.27.0[−][src]

    #[repr(simd)]pub struct __m128d(_, _);

This is supported on x86-64 only.
Expand description

128-bit wide set of two `f64` types, x86-specific

This type is the same as the `__m128d` type defined by Intel, representing a 128-bit SIMD register which internally is consisted of two packed `f64` 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 `__m128d` type has one interpretation. Each instance of `__m128d` always corresponds to `f64x2`, or two `f64` types packed together.

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

## Examples

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

    let two_zeros = _mm_setzero_pd();
    let two_ones = _mm_set1_pd(1.0);
    let two_floats = _mm_set_pd(1.0, 2.0);
