eve::fundamental_width< Type, ABI > Struct Template Reference

Detailed Description

template<typename Type, regular_abi ABI = eve::current_abi_type>
struct eve::fundamental_width< Type, ABI >

Computes the fundamental width of a given type.

Required header: #include <eve/arch/fundamental_width.hpp>

eve::fundamental_width computes the width of the smallest register able to store values of type Type for a given SIMD ABI with no uninitialized lanes.

Template Parameters

Type	Type of value to assess
ABI	SIMD ABI to use as reference. Must models eve::regular_abi.

Member types

Name	Definition
type	The type of width computed for Type

Helper types

template<typename Type, regular_abi ABI = eve::current_abi_type>
using fundamental_width_t = typename fundamental_width<Type, ABI>::type;

Helper variable template

template<typename Type, regular_abi ABI = eve::current_abi_type>
inline constexpr auto fundamental_width_v = fundamental_width_t<Type, ABI>::value;

// Width template inline variable to use with functions like eve::load
template<typename Type, typename ABI = eve::current_abi_type>
inline constexpr fundamental_width<Type,ABI> const fundamental = {};
