| | | | | ------------------------------------------------------------------------------ | | ------------------- | | template< class T, class Abi = simd_abi::compatible<T> > 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().
