static float32x4 simdpp::float32x4::load_broadcast ( const float *  v0 )

static

Creates a float32x4 vector from a value loaded from memory.

    | 0  1  2  3  |
r = [ v0 v0 v0 v0 ]

• In SSE2-SSE4.1 this intrinsic results in at least 2 instructions.

static float32x4 simdpp::float32x4::make_const ( float  v0 )

static

Creates a float32x4 vector from a value known at compile-time.

    | 0  1  2  3  |
r = [ v0 v0 v0 v0 ]

static float32x4 simdpp::float32x4::make_const ( float  v0, float  v1  )

static

Creates a float32x4 vector from two values known at compile-time.

    | 0  1  2  3  |
r = [ v0 v1 v0 v1 ]

static float32x4 simdpp::float32x4::make_const ( float  v0, float  v1, float  v2, float  v3  )

static

Creates a float32x4 vector from four values known at compile-time.

    | 0  1  2  3  |
r = [ v0 v1 v2 v3 ]

float32x4& simdpp::float32x4::operator= ( const float32x4 &  d )

inline

static float32x4 simdpp::float32x4::set_broadcast ( float  v0 )

static

Creates a float32x4 vector from a value stored in a core register.

    | 0  1  2  3  |
r = [ v0 v0 v0 v0 ]

• In SSE2-SSE4.1 this intrinsic results in at least 2 instructions.
• In NEON this intrinsic results in at least 2 instructions.
