template<class V >
auto Dune::Simd::mask (const V &v)
 Convert to mask, analogue of bool(s) for scalars. More...
 
template<class V1 , class V2 >
auto Dune::Simd::maskOr (const V1 &v1, const V2 &v2)
 Logic or of masks. More...

Syntactic Sugar

Templates and functions in this group provide syntactic sugar, they are implemented using the functionality from SimdInterfaceBase, and are not customizable by implementations.

template<class V >
using Dune::Simd::Mask = Rebind< bool, V >
 Mask type type of some SIMD type. More...
 
template<class V >
std::size_t Dune::Simd::lanes (const V &)
 Number of lanes in a SIMD type. More...
 

Detailed Description

User interface of the SIMD abstraction.

This file provides the user interface functions of the SIMD abstraction layer.
