The beginnings of a compiler. 🏎️
Currently compiles +, -, *, /, () using LISP syntax.
Developed for macOS. Could run into problems on Linux with _main rather than main, among other things.
Written in C89 apart from an anonymous union (__extension__).
(* 5 (+ 90 10))
Is compiled to
.intel_syntax noprefix
.globl _main
_main:
push 5
push 90
push 10
pop rdi
pop rax
add rax, rdi
push rax
pop rdi
pop rax
imul rax, rdi
push rax
pop rax
ret
Compiling that with Clang/GCC and running the binary will return 244.
You can check the return value of a program with echo $?.
