Function Documentation

mask_load()

template<typename T , size_t SIMD_WIDTH>

static Vec< T, SIMD_WIDTH > simd::mask_load ( const Vec< T, SIMD_WIDTH > & src, const Mask< T, SIMD_WIDTH > & k, const T *const p )

inlinestatic

Masked versions of load(const T *const).

Does not touch memory if the corresponding mask element is false, so may be used to prevent page faults where a non-masked load would cause a fault.

mask_loadu()

template<typename T , size_t SIMD_WIDTH>

static Vec< T, SIMD_WIDTH > simd::mask_loadu ( const Vec< T, SIMD_WIDTH > & src, const Mask< T, SIMD_WIDTH > & k, const T *const p )

inlinestatic

Masked version of loadu(const T *const).

Does not touch memory if the corresponding mask element is false, so may be used to prevent page faults where a non-masked load would cause a fault.

mask_store()

template<typename T , size_t SIMD_WIDTH>

static void simd::mask_store ( T *const p, const Mask< T, SIMD_WIDTH > & k, const Vec< T, SIMD_WIDTH > & a )

inlinestatic

Masked version of store(T *const, const Vec<T, SIMD_WIDTH> &).

Only stores the elements for which the corresponding mask element is true.

mask_storeu()

template<typename T , size_t SIMD_WIDTH>

static void simd::mask_storeu ( T *const p, const Mask< T, SIMD_WIDTH > & k, const Vec< T, SIMD_WIDTH > & a )

inlinestatic

Masked version of storeu(T *const, const Vec<T, SIMD_WIDTH> &).

Only stores the elements for which the corresponding mask element is true.

maskz_load()

template<typename T , size_t SIMD_WIDTH>

static Vec< T, SIMD_WIDTH > simd::maskz_load ( const Mask< T, SIMD_WIDTH > & k, const T *const p )

inlinestatic

Zero-masked version of load(const T *const).

Does not touch memory if the corresponding mask element is false, so may be used to prevent page faults where a non-masked load would cause a fault.

maskz_loadu()

template<typename T , size_t SIMD_WIDTH>

static Vec< T, SIMD_WIDTH > simd::maskz_loadu ( const Mask< T, SIMD_WIDTH > & k, const T *const p )

inlinestatic

Zero-masked version of loadu(const T *const).

Does not touch memory if the corresponding mask element is false, so may be used to prevent page faults where a non-masked load would cause a fault.
