class simd_mask;
(parallelism TS v2)

The class template simd_mask is a data-parallel type with the element type bool. The width of a given simd_mask instantiation is a constant expression, determined by the template parameters. Specifically, simd_mask<T, Abi>::size() is always simd<T, Abi>::size().


[edit] Template parameters

T - the element type simd_mask applies on
Abi - the ABI type simd_mask applies on
