Bill Currie 35d53d0d77 Fix typedefs and class names once and for all. 
I suspect Holub did them that way as a teaching exercise :P
 2011-02-08 08:20:32 +09:00
Bill Currie 7e2173f268 Remove some old code. 2011-02-08 08:16:36 +09:00
Bill Currie 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.
 2011-02-07 22:16:16 +09:00

Bill Currie 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.
 2011-02-07 15:30:49 +09:00
Bill Currie 65a07ada1c Implement offset dereferences. 2011-02-07 14:56:29 +09:00

Bill Currie d549e5c6b5 Allow enums to be tested. 2011-02-07 11:30:56 +09:00
Bill Currie 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.
 2011-02-07 10:21:54 +09:00
Bill Currie 829fb33e92 Fix converting nil to a pointer type. 2011-02-07 10:10:48 +09:00
Bill Currie b8127f7543 Do not segfault when printing a pointer value with a bogus type 2011-02-07 09:57:26 +09:00
Bill Currie 28ba4b5712 Correct a comment. 2011-02-07 09:56:33 +09:00
Bill Currie d564e6f017 Clean out the old debug prints from emit_function() 2011-02-07 08:46:12 +09:00
Bill Currie 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.
 2011-02-07 08:30:28 +09:00
Bill Currie 1d108a8cec Support emitting symbolic constants. 2011-02-06 20:08:54 +09:00
Bill Currie 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

Bill Currie e27f3fd7c3 Copy the method's params into the method symbol. 2011-02-06 15:14:42 +09:00
Bill Currie 00bba1eb3a Fix creation of uninitialized global variables. 2011-02-06 14:37:25 +09:00
Bill Currie 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
Bill Currie d03fdc5e67 Correctly calculate the size of the ivars of a class. 
Need to include the size of the super class ivars.
