1.27.0[][src]Struct core::arch::x86::__m128d

pub struct __m128d(_, _);
This is supported on x86 only.

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.
