[][src]Struct core::arch::x86::__m64

#[repr(simd)]pub struct __m64(_);
🔬 This is a nightly-only experimental API. (stdsimd #48556)
This is supported on x86 only.

64-bit wide integer vector type, x86-specific

This type is the same as the __m64 type defined by Intel, representing a 64-bit SIMD register. Usage of this type typically corresponds to the mmx target feature.

Internally this type may be viewed as:

(as well as unsigned versions). Each intrinsic may interpret the internal bits differently, check the documentation of the intrinsic to see how it's being used.

Note that this means that an instance of __m64 typically just means a "bag of bits" which is left up to interpretation at the point of use.

Most intrinsics using __m64 are prefixed with _mm_ and the integer types tend to correspond to suffixes like "pi8" or "pi32" (not to be confused with "epiXX", used for __m128i).
