4c69a97ac7 Allow normal declarations within a class implementation. 
I had always been under the assumption that such was illegal in
Objective-C, but after working on Forge, I now know otherwise.

dc5bafb8fb Minimal error recovery. 
No more bailing on the first syntax error. While the recovery is not
perfect (things can get right twisted), qfcc will now continue parsing
after a syntax error.

a4635d79e8 Slightly more informative error locations. 
Inside a class or protocol definition is not "at top level" ;)

530e8fae34 Rework class_type_t to be more useful. 
This allows current_class to refer to procols as well (for error
reporting).

f738ef5dba Remove redundant RETURN statement rule. 
The same effect can be achieved with one rule using opt_expr.

52e844ee48 Produce slightly better v6 modulo code for complex inputs. 
I'm having problems with temp defs, but I imagine this code is rarely used
so I won't worry about it for now. It will, however, make a good test case
for when I rework emit.c after I do some reading.

d981968208 v6 modulo implementation now produces good code. 
At least for simple inputs, anyway. That needs to be tested next.
 2010-12-18 22:21:55 +09:00
Bill Currie
00e50c0ad3 Rewrite the v6 modulo implementation. 
While trying to understand bind expressions, I discovered that the v6
modulo code was incorrect. This version is correct but uses one too many
temps. That's next.

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.

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.

2c84ae4898 Don't let casting in constfold increment users. 
This fixes Deek's temp notice. No new notices have shown up, so this should
be the correct fix. The constant folding code no longer calls cast_expr
directly, but rather uses an internal wrapper that decrements users after
cast_expr increments it, resulting in a no-op.

9a3f4d5a01 Handle method parameters that use incomplete types. 
Compare the method's type pointers rather than the type strings as the pointer
won't change with the struct is completed.

a623fb53a7 Proper support for empty structs and unions. 
They now have a single private, void, unnamed member, resulting in a size of
1 word. This makes empty structs useful for typed opaque handles.
 2010-11-24 17:01:17 +09:00

06cbb941f1 "make dist" fixes 
Since we're using git now, having a rule to make ChangeLog is reasonable.

Also, forgot the remove mention of qfcc.lsm.in when I nuked the file.

669771681a split up and modernize configure.ac 
Most of the guts of configure.ac have been moved to config.d and are then
brought in by m4_include. This will make maintaining configure.ac much easier.

Also drop use of PROGRAM and VERSION, using PACKAGE_NAME, PACKAGE_VERSION, and
on occasion, PACKAGE_STRING instead, and clean out some old files we no longer
need.
