Experiments in LLVM, probably leading to some sort of simple, low-level Lisp language implementation.

Right now I'm working on building a small compiler that parses Lisp expressions to do integer math only.

Eventually, it might become something like a backend for this other Lisp.

For the moment, see compiler_test.go to get an idea of the direction.

$ go build .

$ echo 42 > fortytwo

$ ./lll fortytwo > answer.ll

$ cat answer.ll
declare void @_print_int(i32 %x)

define i32 @main() {
0:
	call void @_print_int(i32 42)
	ret i32 0
}

$ clang answer.ll _print.c -o answer

$ ls -l answer
-rwxr-xr-x  1 jacobsen  staff  49464 Feb 19 20:52 answer

$ ./answer
42

For the moment, I want to support the following use cases.

• Compile and execute expressions from the REPL.
• Compile a program to disk and execute it later, or on another machine.
