go-jit's Introduction

go-jit

JIT compile library for Go

Status

WIP

Synopsis

Basic Operation

package main

import (
  "fmt"

  "github.com/goccy/go-jit"
)

// func f(x, y, z int) int {
//   temp1 := x * y
//   temp2 := temp1 + z
//   return temp2
// }

func main() {
  ctx := jit.NewContext()
  defer ctx.Close()
  f, err := ctx.Build(func(ctx *jit.Context) (*jit.Function, error) {
    f := ctx.CreateFunction([]*jit.Type{jit.TypeInt, jit.TypeInt, jit.TypeInt}, jit.TypeInt)
    x := f.Param(0)
    y := f.Param(1)
    z := f.Param(2)
    temp1 := f.Mul(x, y)
    temp2 := f.Add(temp1, z)
    f.Return(temp2)
    f.Compile()
    return f, nil
  })
  if err != nil {
    panic(err)
  }
  fmt.Println("result = ", f.Run(2, 3, 4))
}

Call defined Go function during JIT runtime

package main

import (
  "fmt"

  "github.com/goccy/go-jit"
)

// func f() int {
//   return callback(7, 8)
// }

func callback(i, j int) int {
  fmt.Printf("callback: i = %d j = %d\n", i, j)
  return i * j
}

func main() {
  ctx := jit.NewContext()
  defer ctx.Close()
  f, err := ctx.Build(func(ctx *jit.Context) (*jit.Function, error) {
    f := ctx.CreateFunction(nil, jit.TypeInt)
    rvalues, err := f.GoCall(callback, []*jit.Value{
      f.CreateIntValue(7), f.CreateIntValue(8),
    })
    if err != nil {
      return nil, err
    }
    f.Return(rvalues[0])
    f.Compile()
    return f, nil
  })
  if err != nil {
    panic(err)
  }
  fmt.Println("result = ", f.Run(nil))
}

go-jit's Issues

This project seems to have wrong license?

It seems like this project is licensed as MIT, but it contains LGPL code from libjit. Those two licenses are not compatible to be used as source files in the same project. As far as I know (I am no lawyer) this project should probably link with libjit dynamically, to be able to use it legally.

error: use of unknown builtin '__builtin_apply' [-Wimplicit-function-declaration]

hi, I use this repo and run its demo code in my M1 Mac book pro. It seems it can not build up. The error is below:
