ef2ad46f7a Convert complex types to a suitable low-level type. 
This takes care of moving structures etc around.
 2011-02-07 10:55:09 +09:00
Bill Currie
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.

829fb33e92 Fix converting nil to a pointer type. 2011-02-07 10:10:48 +09:00

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).
 2011-02-07 08:32:52 +09:00
Bill Currie
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.

6b7a81f5a7 Run find_type() early on enums and structs. 2011-02-06 20:07:19 +09:00
Bill Currie
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
Bill Currie
2860a8b28b enum too is a scalar. 2011-02-06 20:01:55 +09:00

Bill Currie
2f7b892452 Fix passing messages to classes. 
Rename class_pointer_def() to class_pointer_symbol() and use it when a
class name is used as the receiver of a message.
 2011-02-06 14:34:40 +09:00
Bill Currie
67957a14df Bring back convert_name(), but siimplified. 
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.
 2011-02-06 14:29:14 +09:00
Bill Currie
d03fdc5e67 Correctly calculate the size of the ivars of a class. 
Need to include the size of the super class ivars.
 2011-02-05 00:04:35 +09:00

690ae1cb57 Fix send_message(). 2011-02-04 23:49:25 +09:00
Bill Currie
29fbc3b073 Struct and ivar declarations now seem to work. 
However, not bit-fields.
 2011-02-04 23:48:58 +09:00
Bill Currie
1f6abb2cce Minor cleanups to message_expr(). 
Fix for class names no longer being pointers to the class.
 2011-02-04 23:22:51 +09:00

eff3957487 Resurrect the address expression code for arrays etc. 
This fixes selector finding.

Bill Currie
f721144ca5 Rewrite emit_ivars to use emit_structure. 
The old code was broken anyway :) (it was segfaulting).
 2011-02-04 15:11:47 +09:00
Bill Currie
acb3c0da11 Fix class initialization. 2011-02-04 14:29:47 +09:00
Bill Currie
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.
 2011-02-04 08:26:16 +09:00
Bill Currie
e04ed72afa Increment the index when emitting array elements. 
Oops :)
 2011-02-04 08:25:27 +09:00

Bill Currie
dc6296e9b1 Allow ivars to use typedefs and other classes. 2011-02-03 18:03:37 +09:00
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
Bill Currie
79df3d2cca Put newly created classes into the symbol table. 2011-02-03 17:28:49 +09:00

Bill Currie
22ccd41164 Give struct types a name. 
Use the struct/union's name (minus "tag ") for the type name.
 2011-02-03 10:52:12 +09:00
Bill Currie
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
52799a4e1c Must merge specifiers :P 2011-02-02 22:59:08 +09:00

Bill Currie
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
Bill Currie
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.
 2011-02-01 21:15:51 +09:00
Bill Currie
917c5f08b0 Make a var representing the default type. 
The default type for vars is integer for ruamoko and float for v6 qc.
 2011-02-01 21:12:02 +09:00
Bill Currie
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.
 2011-01-30 21:43:56 +09:00

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.

c158b14286 Remove the labels list from the pr struct. 
I'm not sure they were ever needed.
 2011-01-28 11:40:25 +09:00

Conditional branches and goto now go to the correct location.

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.
 2011-01-27 15:44:11 +09:00

c7bbd40df6 Give special treatment to opcodes that have void operand types. 2011-01-27 15:44:11 +09:00
Bill Currie
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.
 2011-01-27 15:44:11 +09:00

f532fbc6df Convert all integer operands to float for v6 progs. 
Converting only opc is no longer enough.
 2011-01-27 15:43:59 +09:00

1ed1efbdfb Implement the ROTL macro correctly. 
Bit rotation requires unsigned ints.
 2011-01-27 15:43:50 +09:00

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

Bill Currie
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
27c5139612 Give defspaces some backing memory. 
I'm not sure I want all defspaces to have backing memory, but this will do
for now.
 2011-01-25 12:16:13 +09:00

34ffce50fa Ensure current_symtab gets set at the start of parsing. 
current_symtab must be set even if the first thing encountered is a syntax

483cbeba03 Fix a few FIXMEs. 2011-01-24 21:13:37 +09:00
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.

4ac80c2932 Get qfcc running again. 
It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)

246778b5de Use function pointer tables instead of switch.

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).

0d01930056 Link a bool to its block rather than the block's head.
