Struct core::arch::x86::__m128 1.27.0[−][src]
#[repr(simd)]pub struct __m128(_, _, _, _);
This is supported on x86 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.
