SIMD operations and types?

[L2NE-dev]

There are not enough SIMD operations in AssemblyScript and the corresponding data types. I propose to add either Intrinsics (and adding a standard library with classes), or immediately make data types with SIMD operations.

// 'simd' is wrapper class with data and operator overloads, also can be casted
// 'i32x4h' is static class with type info and typed operations (if float, so float ops)
export function simd_add(x: simd<i32x4h>, y: simd<i32x4h>): simd<i32x4h> {
  return x + y;
}

Currently AssemblyScript doesn't implement SIMD but in future names will have simpler type name conventions:

i32x4
u16x8
f32x4
f64x2
and etc

which in same type could be just aliases for tuples. type i32x4 = [i32, i32, i32, i32] or type i32x4 = { x: i32; y: i32; z: i32; w: i32 } or even type i32x4 = [i32, i32, i32, i32] | { x: i32; y: i32; z: i32; w: i32 }. And provide property accessors for x, y, z, w and swizzles:

var a: i32x4 = [1, 2, 3, 4];
var b = a.xxyy

Does (or will) AssemblyScript support SIMD intrinsics (with abstract v128 type)?

[MaxGraey]

Of course it will. AS always provide low-level intrinsic api for wasm
