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 | 
| Abi | - | tag type used to determine the number of elements and storage |
