std::experimental::simd

Defined in header <experimental/simd>
template < class T, class Abi = simd_abi:: compatible <T> > class simd;		(parallelism TS v2)

The class template simd is a data-parallel type. The width of a given simd instantiation is a constant expression, determined by the template parameters.

An ABI tag is a type in the simd_abi namespace that indicates a choice of size and binary representation for objects of data-parallel type.

Template parameters

T	-	element type; an arithmetic type other than bool
Abi	-	tag type used to determine the number of elements and storage

Helper alias templates

template < class T, int N > using fixed_size_simd = std:: experimental :: simd <T, std:: experimental :: simd_abi :: fixed_size <N>> ;
template < class T > using native_simd = std:: experimental :: simd <T, std:: experimental :: simd_abi :: native <T>> ;
