import (
	"fmt"
	"os"
	"os/exec"
)

func main() {
	compile("123")
	os.Exit(0)
}

func compile(code string) {
	output := fmt.Sprintf(tmpl, code)
	os.WriteFile("a.out.ll", []byte(output), 0666)
	exec.Command("clang", "-Wno-override-module", "-o", "a.out", "a.out.ll").Run()
}

const tmpl = `
define i32 @main() {
    ret i32 %v
}
