Interactive Assembler for Go.

IASM -- Interactive Assembler for Go.

Dual-purpose assembly engine written in pure Golang.

The x86_64 package was ported from a Python module PeachPy, with some adaption to the Go language features.

Currently, IASM only supports x86_64, because it's the only architecture I am very familiar with.

It can be used as a dynamic assembler

This can be used to implement:

• JIT engine
• Compiler backend
• And more !

See x86_64/program_test.go for more info.

It can also be used as a static assembler

For macOS:

git clone https://github.com/chenzhuoyu/iasm
cd iasm
go build ./cmd/iasm
./iasm -h
./iasm -f macho -D __Darwin__ -o helloworld example/helloworld.s
./helloworld 

It also contains an interactive REPL shell

Just run IASM without any arguments.

./iasm

Missing Package x86_64

github.com/cloudwego/iasm/x86_64: module github.com/cloudwego/iasm@latest found (v0.1.0), but does not contain package github.com/cloudwego/iasm/x86_64

https://github.com/cloudwego/iasm/actions/runs/8525216623

All your tests fail. I cannot update our dependencies as your package is broken.

Fix ASAP please

Too big binary file size

mkdir binarysize
cd binarysize
go mod init binarysize

add main.go with following content:

package main

import (
	"fmt"

	"github.com/bytedance/sonic"
)

func main() {
	m := map[string]string{
		"hello": "world",
	}
	str, err := sonic.MarshalString(m)
	if err != nil {
		fmt.Println(err)
		return
	}
	fmt.Println(str)
}

go mod tidy
go build main.go

ls -lh binaryzie
# the file size is nearly ~26MB
