The parser now gets a stream of tokens, rather than needing to worry about
loading files itself.
This also reworks the lexer's idea of what constitutes a Token -- it's now a
pair (Meta, TokenType), so it's always easy to pull out/rewrite the metadata --
and adds proper support for lexing preprocessor directives, rather than just
treating them as reserved words.
The compiler itself is under the GPLv2+; the support code that gets built into
user programs is under the LGPLv2+. This matches the existing practice for the
KRoC project.
(As with Occade, I've used the new GPLv3-style license header in the source
files, though, since that avoids having to update the FSF's postal address.)
This does about the minimum necessary for assembly analysis to work. It assumes
that any function it hasn't been able to analyse itself needs 512 bytes (most
need far less); it doesn't do any flow analysis; it doesn't do a lot of sanity
checking. However, it produces sensible numbers, and works with the demos I've
tried so far.
I was originally going to make this a separate tool, but there are a number of
bits of the code can be nicely reused, so it's a separate "operating mode" in
the existing program (as is parse-only mode now).
