std::experimental::simd_mask

Template:cpp/experimental/simd/simd mask/navbar content

 

Defined in header <experimental/simd>
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().

Template parameters

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

Helper alias templates

Template	Definition
template <class T, int N> using fixed_size_simd_mask	simd_mask<T, simd_abi::fixed_size<N>>
template <class T> using native_simd_mask	simd_mask<T, simd_abi::native>

Member types

Member type	Definition
value_type	bool
reference	implementation-defined
simd_type	simd<T, Abi>
abi_type	Abi

Member functions

(constructor)	constructs a simd_mask object (public member function)
copy_from	loads from address (public member function)
copy_to	stores to address (public member function)
operator[]	accesses specified element (public member function)
operator!	negates each element (public member function)
size [static]	returns the number of elements (public static member function)

Non-member functions

operator&& operator||	element-wise logic operators (function)
operator& operator| operator^	element-wise bitwise operators (function)
operator&= operator|= operator^=	element-wise compound operators (function)
operator== operator!=	element-wise relation operators (function)
