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 |
