As of 184c39579227 ("Re-work the parser from scratch") the parser has a
proper AST, and the assembler has to traverse it accordingly.
Moreover, the assembler has been stripped from a lot of unneeded memory
allocations and it's overall more keen on using mere references when
possible.

Re-work the parser from scratch2024-12-12T06:41:30ZMiquel Sabaté Solàmikisabate@gmail.com2024-09-26T13:53:57Zurn:sha1:184c39579227c0add80a61d489c242120001d6b6
The initial implementation was incredibly naive on how complex an
assembler can actually be. Because of this, it never bothered to define
and produce a proper AST, and hence it was overall extremely fragile on
(not so) corner cases.
This commit re-writes everything from scratch for the parser, and it
should really be the last fundamental change to the parser other than
minor additions/features here and there.

Add support for procedures2024-12-12T06:33:40ZMiquel Sabaté Solàmikisabate@gmail.com2024-07-17T13:09:36Zurn:sha1:376dcb684ce779a7051bbc9a95359114e94cae5e
Procedures are marked with the '.proc' control statement and work both
as a scoping mechanism and as a label that can be referenced.

This is a bare bones implementation of it, and there's a lot of nuance
that it's being missed, but at least the fundamentals have been
implemented already.

Add the notion of mapping2024-12-12T06:31:52ZMiquel Sabaté Solàmikisabate@gmail.com2024-07-15T06:55:57Zurn:sha1:c6c9aa4e5f3e5a01fcb9ccabf6dbd2f6da277650
Mappings and segments are fundamental blocks on how code is distributed
both on the actual ROM File and in the memory layout.

A lot is missing and there is a long road ahead to make the assembler
even work.
