Struct core::arch::x86_64::__m512d [−][src]
#[repr(simd)]pub struct __m512d(_, _, _, _, _, _, _, _);This is supported on x86-64 only.
Expand description
512-bit wide set of eight f64 types, x86-specific
This type is the same as the __m512d type defined by Intel,
representing a 512-bit SIMD register which internally is consisted of
eight packed f64 instances. Usage of this type typically corresponds
to the avx and up target features for x86/x86_64.
Note that unlike __m512i, the integer version of the 512-bit
registers, this __m512d type has one interpretation. Each instance
of __m512d always corresponds to f64x4, or eight f64 types packed
together.
Most intrinsics using __m512d are prefixed with _mm512_ and are
suffixed with “pd” (or otherwise contain “pd”). Not to be confused with
“ps” which is used for __m512.
