## Usage

```golang

package main

import (

    "fmt"

    "github.com/mengzhuo/intrinsic/sse2"

)

func main() {

    src := []float32{3.14, 2.17}

    dst := []float32{2.17, 3.15}

    sse2.MAXSDm64float32(src, dst)

    fmt.Print(src, dst) //[2.17 3.15] [2.17 3.15]

}

```

## Benchmarks

SSE2

it will provide about 6x-7x performance enhancement.

## Development

All codes in subdir is generated by scanner.go , see Makefile for more detail.

x86.csv and x86desc.csv are from another repos in https://github.com/mengzhuo/x86data
