Defined in header <experimental/simd>
template< class T > using native = /*implementation-defined*/;		(parallelism TS v2)

native<T> is an implementation-defined alias for an ABI tag. This is the primary ABI tag to use for efficient explicit vectorization.

Notes

The intent is to use the ABI tag producing the most efficient data-parallel execution for the element type T that is supported on the currently targeted system. For target architectures without ISA extensions, the native<T> and compatible<T> aliases will likely be the same. For target architectures with ISA extensions, compiler flags may influence the native<T> alias while compatible<T> will be the same independent of such flags.
