Detailed Description

SIMD vector of 4 single-precision floating-point real numbers, operations on which use SSE instructions available on all recent x86 hardware.

Constructor & Destructor Documentation

VectorSSEFloat()

libint2::simd::VectorSSEFloat::VectorSSEFloat ( T a )

inline

Initializes all elements to the same value.

Parameters

a	the value to which all elements will be set

Member Function Documentation

convert_aligned()

void libint2::simd::VectorSSEFloat::convert_aligned ( T * a ) const

inline

writes this to a

Note

a must be aligned to 32 bytes

load_aligned()

void libint2::simd::VectorSSEFloat::load_aligned ( T const * a )

inline

loads a to this
