505e141633 Ensure the class symbol is in the symbol table. 2011-02-08 17:08:58 +09:00
Bill Currie
3c64ae7b66 Fix overzealous type merging. 
Use the type name instead of the symbol table for comparing
struct/union/enum types.

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).

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.

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

0624408317 Move the diagnostic functions into their own file. 2011-01-24 21:54:57 +09:00
Bill Currie
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.

5deda9c9b9 Clean out ex_def as ex_symbol replaces it. 2011-01-19 22:25:04 +09:00
Bill Currie
e08efe036b Move the constant expression values into their own struct. 2011-01-19 08:43:24 +09:00
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
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.

75ec6bf244 Clean out some unnecessary types from the progs engine and clean up the mess. 
This is a nasty commit, sorry, but 99% of the commit is interdependent.

5627e43465 Use the method's selector rather than its def name in error messages. 2011-01-03 16:25:29 +09:00
Bill Currie
a1f36a9944 Make new_function take a def rather than a name. 
Moves into new_function some code that should have been there in the first
place.
 2011-01-03 16:25:29 +09:00
Bill Currie
530e8fae34 Rework class_type_t to be more useful. 
This allows current_class to refer to procols as well (for error
reporting).
 2011-01-03 16:25:29 +09:00
Bill Currie
699799bfc8 Don't warn when adding a new method to an implementation. 
Methods defined in the implementation but not declared in the interface are
just fine.
 2010-12-16 20:04:08 +09:00
Bill Currie
eace5b3c81 Get message checking working properly. 2010-12-16 16:41:16 +09:00
Bill Currie
4481ba9b0d Allow explicit references to classes and categories. 
Use "@reference ClassName;" or "@reference ClassName(CategoryName);" to
create a refence to the class or category, forcing the defining object file
to be linked into the program when the object file is part of a library.

3fb03fc2be hah, should have been using __attribute__((used)) all that time (rather 
than __attribute__((unused))). fixes the missing console in -x11
 2005-08-04 15:27:09 +00:00

5f34f87b58 ivar access control seems to work now :) 
This is an imperfect revision of history.
 2004-11-13 01:37:00 +00:00
Bill Currie
64cc8c60d2 compile time protocol support seems to be complete now. fortunatly, protocols had never been written out so the corrections to the protocol related stuctures do not need a progs version bump. runtime protocol support hasn't been fully tested yet. 
+load runtime support seems to be working.

This is an imperfect revision of history.

385a90e8fb correct pr_symtab_t to include the pointer to the array of selectors used 
in the module. Unfortunatly, this requires a version bump on both qfo and
progs files due to the changes structure layout.
