Member Typedef Documentation

◆ value_type

template<typename T>
using internal::VectorizedArrayTrait< T >::value_type = T

Define scalar value type.

Definition at line 6410 of file vectorization.h.

◆ vectorized_value_type

template<typename T>
using internal::VectorizedArrayTrait< T >::vectorized_value_type = VectorizedArray<T>

Define vectorized value type for internal vectorization.

Definition at line 6424 of file vectorization.h.

Member Function Documentation

◆ width()

template<typename T>
constexpr std::size_t internal::VectorizedArrayTrait< T >::width ( )
inlinestaticconstexpr

Return the width of template type.

Definition at line 6416 of file vectorization.h.

◆ stride()

template<typename T>
constexpr std::size_t internal::VectorizedArrayTrait< T >::stride ( )
inlinestaticconstexpr

Return a stride which defines how often the template type T fits into the vectorized_value_type. This is useful to write vectorized templated code where the internal computation is vectorized and the user interface is optionally scalar or also vectorized.

Definition at line 6433 of file vectorization.h.

◆ get() [1/2]

template<typename T>
value_type & internal::VectorizedArrayTrait< T >::get ( value_type & value,
unsigned int c )
inlinestatic

Get a reference to scalar value (on lane 0).

Definition at line 6442 of file vectorization.h.

◆ get() [2/2]

template<typename T>
const value_type & internal::VectorizedArrayTrait< T >::get ( const value_type & value,
unsigned int c )
inlinestatic

Get a read-only reference to scalar value (on lane 0).

Definition at line 6454 of file vectorization.h.

◆ get_from_vectorized() [1/2]

template<typename T>
value_type & internal::VectorizedArrayTrait< T >::get_from_vectorized ( vectorized_value_type & values,
unsigned int c )
inlinestatic

Get a reference to scalar value on lane c from a vectorized values field.

Definition at line 6466 of file vectorization.h.

◆ get_from_vectorized() [2/2]

template<typename T>
const value_type & internal::VectorizedArrayTrait< T >::get_from_vectorized ( const vectorized_value_type & values,
unsigned int c )
inlinestatic

Get a read-only reference to scalar value on lane c from a vectorized values field.
