Use the type name instead of the symbol table for comparing
struct/union/enum types.

265a244ba2 Set the symbol type for structs etc as soon as the tag is created.
Tags (struct/union/enum) are always types.

ef2ad46f7a Convert complex types to a suitable low-level type.
This takes care of moving structures etc around.

b629c12b31 Do not change the type of the return operand.
Doing so made a mess of returning expressions. It was probably a holdover
from before getting instructions with void operand types working.

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).

3025e04ac5 Partially resurrect field_expr()
For now, only entity.field and ivar access via a pointer have been
implemented. The rest will come later as needed.

d54a96e68a Make enum values visible.
Put them in the current symbol table as well as the enum symbol table. The
latter is really just for keeping track of what values are in the enum.
2011-02-06 20:06:09 +09:00

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

f721144ca5 Rewrite emit_ivars to use emit_structure.
The old code was broken anyway :) (it was segfaulting).

04b86fcdb7 Move the Objective-QC structs from type.c to class.c 2011-02-04 12:07:32 +09:00
Bill Currie
7b22bfba63 Better Objective-QC keyword detection.
Use a flag in the keyword struct rather than checking for "@" in the
keyword. This catches such keywords as "id" and "Protocol" as well.
2011-02-04 08:38:58 +09:00
Bill Currie
993bee4f59 Do not count unimplemented methods.
The method emitter skips unimplemented methods, so counting them when
figuring out how many methods to emit leads to a segfault.

Bill Currie
2203903bb2 Temporarily splice the class's ivar chain into the symbol table.
The root class's ivar symbol table needs to be connected to the global
symbol table while building the current class's ivar symbol table. This
allows access to other classes and typedefs.
2011-02-03 18:02:49 +09:00

22ccd41164 Give struct types a name.
Use the struct/union's name (minus "tag ") for the type name.

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

52799a4e1c Must merge specifiers :P 2011-02-02 22:59:08 +09:00

1fe031e8cb Build C style var/func/abs decl types from the outside in.
QuakeC style are built from the inside out.
2011-02-02 15:15:04 +09:00
Bill Currie
7fb8c8247e Don't do a find_type on the parsed function.
This is needed for C style declarations, but breaks QuakeC style. The fix
is to do the find_type once the return type has been filled in.
2011-02-02 15:08:59 +09:00
Bill Currie
1452da676d Allow types to be built from the outside in.
This is required for C style decl processing.
2011-02-02 15:07:44 +09:00

ac91e9376b The big type-system rewrite. Horribly broken :)
While broken, it is good enough to compile modulo.r.

This gives qfcc C's type system with QC specifics bolted on top (rather
than trying to cram C's type system into QC's). Pointers and arrays now
use C syntax and semantics (though I think there's a lot of breakage in
there at the moment). Functions themselves are still dual mode: both QC
style and C style are available.

c53001800a Create a struct for representing specifiers.
The specifiers are yet to come (next few commits), but this will be
necessary when they do.

917c5f08b0 Make a var representing the default type.
The default type for vars is integer for ruamoko and float for v6 qc.

54c14eb899 Add "return" to pascal.
I'm still not sure I'll keep it, but it's useful for testing.
2011-01-30 22:16:59 +09:00
Bill Currie
e7424e1496 Don't segfault on bare return statements.
I will probably need to do something about the required operand for v6
progs, but this will do for now.

d80a3413e5 Fix a segfault when freeing locations.
When chasing linked lists with a double pointer, must check the first
dereference and not the pointer itself.

4837e0bd18 Fix most of the FIXMEs in qfcc.c.
Functions and defs seem to be relocated correctly. Constants are very
broken, however.

834417b8c8 Add "debug" diagnotic printing, and use it.
Debug diagnostics are silent for verbosity levels less than 1.

Bill Currie
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.

71b5decbe8 Get assignments to .return working.
I really do not like the mechanism I currently use for handling pointer
derefences vs pointer assignments, but this will have to do for now until
I can get qfcc producing code again.
