Infinity compiler update

I had hoped to make a first release of i8c today but I still have one open issue so you’ll have to wait until next week. Until then here’s some note source for you to ponder:

define test::factorial returns int
    argument int x
    extern func int (int) factorial

    swap
    dup
    load 1
    bne not_done_yet
    return

not_done_yet:
    dup
    load 1
    sub
    swap
    rot
    swap
    call
    mul

As hints I will a) point you at section 2.5 of the DWARF spec, and b) mention that argument and extern directives instruct the caller and runtime respectively to push entries onto the stack.

Your homework is to see how much of the language and runtime you can infer from this one function.

You may ask questions.
