35d53d0d77 Fix typedefs and class names once and for all. 
I suspect Holub did them that way as a teaching exercise :P

7e2173f268 Remove some old code. 2011-02-08 08:16:36 +09:00

d6b10c99aa Most, if not all, of the fixes needed to get qwaq building. 
This is pretty much just changing [] to * and moving [N] to the other side
of the variable name.

3c64ae7b66 Fix overzealous type merging. 
Use the type name instead of the symbol table for comparing
struct/union/enum types.
 2011-02-07 20:48:01 +09:00
Bill Currie
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.
 2011-02-07 10:55:09 +09:00

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

d564e6f017 Clean out the old debug prints from emit_function() 2011-02-07 08:46:12 +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.

1d108a8cec Support emitting symbolic constants. 2011-02-06 20:08:54 +09:00

e4ac92b5f2 Auto-cast between enums and the default type. 2011-02-06 20:08:16 +09:00
Bill Currie
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

f2c272f0b8 Make adding a symbol to multiple tables an internal error. 2011-02-06 20:00:14 +09:00

59d3dc6ae0 Check early for assignment of a class pointer to id. 2011-02-06 14:35:17 +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

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

c542e1a453 Possibly fix normal methods. 2011-02-04 22:31:23 +09:00
