76034861c9 Implement direct ivar access in methods.
A warning needs to be generated for access to ivars in a class method, but
it seems to work (unable to check due to other errors).

67957a14df Bring back convert_name(), but siimplified.
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.

d12cdca758 Functions and enums now seem to be working properly.
find_type now operates recursively (depth-first) so built up typechains
work as expected.

@overload is treated as a specifier (directly as a storage class, similaar
to typedef).
2011-02-03 10:48:12 +09:00
Bill Currie
400abe7fce Allow freeing of typechains. 2011-02-02 15:15:24 +09:00

c53001800a Create a struct for representing specifiers.

834417b8c8 Add "debug" diagnotic printing, and use it.

cdea1d07aa Produce code for progs.src mode.
Separate compilation will take fixing object files.

The generated code is broken due to various relocation fixups being
broken, and float immediates seem to be badly broken.

Debug information is broken too.

Bill Currie
6ce3c5a59a Get statments being emitted to the code segment.
The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled
linked list).
2011-01-25 15:46:48 +09:00

a648f043de Give functions their own defspace.
The defspace is propogated through the function's sub-scopes.
2011-01-25 12:34:45 +09:00
Bill Currie
726f293d0d Allocate space for defs and handle basic initializations.

d618e51dc8 Move save_string and make_string into strpool
Might not be the perfect place, but at least they're strongly related.

Bill Currie
afc5b2827d Simplify def handling, use far data.
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.

Also, start using far data for ObjQC structures.

The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

52b561f7cb Nuke bind expressions.
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).
2011-01-21 19:07:58 +09:00

f8cc347dce Print expressions as dot files.
While the resulting images can be a little confusing, they're much easier

Bill Currie
87ce9f5333 Get basic function creation working.
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.
2011-01-18 12:47:13 +09:00
Bill Currie
8fb1b49a9d Add support for function symbols. 2011-01-18 10:46:42 +09:00
Bill Currie
ea3895805b Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.

emit.c has been gutted in the spirit of "throw one away".

There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.
2011-01-17 22:34:41 +09:00

Bill Currie
fb8b3d1211 Rework the lexer and parser to use symbols instead of defs.
Currently parses the test program just fine, but code generation is very
very broken.
2011-01-13 14:58:16 +09:00
Bill Currie
8f71986306 Add symbol expressions (like def expressions).
They will eventually replace def expressions. Currently quite broken.

ac14db7b1b Create a function to ease param list building.
This is especially useful for QuakePascal, but it will mean I'll be able to
get rid of the parameter reversals in Ruamoko later on.
