SIMD.swizzle

SIMD.js has been taken out of active development in TC39 and removed from Stage 3. It is not being pursued by web browsers for implementation anymore. SIMD operations exposed to the web are under active development within WebAssembly, with operations based on the SIMD.js operations.

The static SIMD.%type%.swizzle() method creates a new SIMD data type instance with the lane values swizzled (re-ordered).

Syntax

SIMD.Float32x4.swizzle(t, s0, s1, s2, s3)
SIMD.Float64x2.swizzle(t, s0, s1)

SIMD.Int8x16.swizzle(t,s0,s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15)
SIMD.Int16x8.swizzle(t, s0, s1, s2, s3, s4, s5, s6, s7)
SIMD.Int32x4.swizzle(t, s0, s1, s2, s3)

SIMD.Uint8x16.swizzle(t,s0,s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15)
SIMD.Uint16x8.swizzle(t, s0, s1, s2, s3, s4, s5, s6, s7)
SIMD.Uint32x4.swizzle(t, s0, s1, s2, s3)

Parameters

t

An instance of a SIMD type to be swizzled / re-ordered.

s0-s15

index in t for lanes s0-s15.

Return value

A new SIMD data type with the lane values swizzled (re-ordered).

Description

The static SIMD.%type%.swizzle() method can be used to re-order a SIMD data type.

Examples

Swizzling a Float32x4

var t = SIMD.Float32x4(1, 2, 3, 4);

SIMD.Float32x4.swizzle(t, 1, 2, 0, 3);
// Float32x4[2,3,1,4]
