std::experimental::simd_cast, std::experimental::static_simd_cast

Header: <experimental/simd>

Cast a simd object to another simd object. If V is T, returns simd<T, Abi>; otherwise, if V is a scalar type, returns simd<V, simd_abi::fixed_size<simd<T, Abi>::size()». Otherwise, V must be a simd type, and the function returns V.

# Declarations

template< class V, class T, class Abi >
/*see below*/ simd_cast( const simd<T, Abi>& v ) noexcept;

(parallelism TS v2)

template< class V, class T, class Abi >
/*see below*/ static_simd_cast( const simd<T, Abi>& v ) noexcept;

(parallelism TS v2)

# Parameters

# Return value

A simd object with the i-th element initialized to static_cast(v[i]), where To is the output element type as specified.

# Notes

The TS specification is missing simd_cast and static_simd_cast overloads for simd_mask. The libstdc++ implementation provides the missing overloads in the std::experimental::__proposed namespace. If you already use the

shortcut, you might be interested to use

instead. Alternatively, libstdc++ implements a __cvt() member function in simd_mask, which allows implicit conversion of the mask. See also: https://github.com/VcDevel/std-simd/issues/41
