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 `f64x8`, or eight `f64` types packed together.

The in-memory representation of this type is the same as the one of an equivalent array (i.e. the in-memory order of elements is the same, and there is no padding between two consecutive elements); however, the alignment is different and equal to the size of the type. Note that the ABI for function calls may not be the same.

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`.
