4e86b28b59 Use the def type rather than expression type to select the init method. 
Local defs may be initialized with non-constant expressions, which
includes function calls. Both function calls and aggregate initializers
use block expressions.

19f6faf0ad Fix aggregate initializers. 
Initializing arrays and structs seems to be working.

3a1e467ae8 Non-bogus syntax and warning fixes for ruamoko/cl_menu. 
Sadly, there are many bogus warnings and other errors. qfcc is still very
sick :(.

9ac6929cf7 Syntax fixes for ruamoko/game. 
This one actually would compile if object files were working.

da3ac388fe Syntax fixes for ruamoko/gui. 
Once aggregate initializers are working, ruamoko/gui will "compile"
(no object files, and still the bogus integer constant into ... warning).

5fa349927f Preserve the ivars inheritance chain across build_struct(). 
build_struct() unlinks the structure symbol table from its parent, but
that breaks the ivar inheritance chain.

f1fccb19dd Allow same-type re-declarations of uninitialized variables. 
This is especially important for declaring variables that were previously
declared external.

4c63a0bad6 Generate a warning when creating a var with no type. 
This makes the internal error in new_def() non-functional, but the warning
will catch the bug and there's no harm in leaving the test in new_def().

ee866ae3a6 Enable the small struct optimization. 
For now, anyway. It would probably be much better to handle this sort of
thing in the optimizer stage.

bcaf3687c5 Fix loading structs into params via an offset pointer. 
For certain values of "fix" :/. The code is ugly, but it does the right
thing: calculate the effect address and use the resulting pointer in a
move instruction.

e10d561459 Treat small structs as integers (disabled). 
This is more to stash away a potential optimization. I need to fix the
real problem first.

c139099294 Put another bandaid on the type creation system. 
It seems that building types is very fragile: all too easy to fix things
in one place and break something somewhere else. I guess the type system
will need a comlete rewrite at some stage.

595019d86e Fix some problems found by the new qfcc. 
With this, ruamoko/lib almost compiles (though no object files are output).
Just some bogus "redeclared" errors and an improperly implemented
statement that produces an ice.

daae0284a1 Work around a warning about passing int constants into ... 
I'm not sure why this is happening now when it didn't in the old qfcc,
but this will take care of the warning for now until I can get around to
fixing it.

e0d61705b4 And fix build_struct for built-in struct types. 
The previous fix broke builtin structs (eg, @param). Calling find_type()
for built-in structs has proven to be a bad idea :)
 2011-02-13 21:07:22 +09:00
Bill Currie
a19b7ec8f9 Make struct decls actually work. 
find_type() does type comparisons based on tag name for struct/union/enum
but when it returns the previous tag (eg, from "struct foo;") the returned
type has a null symtab pointer, so setting the symtab pointer in the type
before calling find_type() only throws away the symtab. Thus, since
find_type() doesn't check the symtab pointer when comparing the types, set
the symtab pointer after calling find_type().

976ff8a6bb Allow cast expressions to be lvalues. 
These really need to be alias expressions rather than cast expressions
so the two can be separated as cast expressions should not be lvalues.

547f361bd3 Allow (void) qc-style functions. 2011-02-13 17:37:11 +09:00
Bill Currie
d75c35ba30 Allow qc style function params. 
Due to ambiguities in the grammar, qc-style function params and c-style
function params had to be completely separated. This means that qc-style
functions can not use pointers and must use qc-style function declarations
for parameters, and c-style functions must use c-style param declarations.
While this rule is tedious for converting the Ruamoko library, it does
actually make for a more consistent language.

0b5565396b Add a class type to symbols and rework the CLASS_NAME handling. 
This fixes the problem with [Array alloc] producing a warning about Class
not repsonding to -alloc.

The fix for pointers broke constants (particularly, enums). Oops.

c4f364fd37 Emit pointers properly. 
Rename ReuseConstant to emit_value and use emit_value to emit any non-short
constant. This fixes the null pointer in the call to __obj_exec_class.
