b522853765 Ensure the target of def_op relocs gets updated. 
These occur only when switch statements use jump tables, thus why the
problem went unnoticed :/

237f11c472 Fix cast expressions. 
Casting between ints and floats needs special treatment to get the
conversion operator, but other casts need to be aliases.

38b25e0c38 Do not double-allocate space for immediates. 
Caused by changed semantics in def creation.

2de7733b6a Fix initialized variable type handling. 
Same problem as initialized constants :P

8e18c76bde Make initialized variables defs rather than immediate constants. 2011-03-30 19:58:09 +09:00

7dbd2ec172 Allow field aliasing. 
Initializing a field variable to another field will set the new field to
point to the same location. No type checking is done.

eg:
.SEL thinkMethod = think;

a7cfe3b215 Preserve the current class across protocol defs. 
It seems that protocol defs are allowed in class implementations, so don't
let the protocol def kill the current class for the class implementation.

71af121665 Detect missing @end tags. 
Give a warning when @end is forgotten in class implementations.

8d3508cf20 Allocate space for temp defs using size rather than type. 
Statement operands throw away the high level type information, so store
type size in the operand and use this size for allocating space for temps
rather than using the low-level type.

d4be914019 Fix initialized vector variables. 
The whole initialized variable system is wonky, but it will do for now.

f1d9570dc8 Fix constant value type handling. 
Rename immediate.[ch] to value.[ch] and clean up the mess.

Add convert_value() to convert the type of a value (only scalar types).

1219df0872 Fix field immediates. 
Field immediates need to be treated the same way as pointer immediates when
merging values.

46093c0937 Use the correct meta type for spacial types. 
Although vector and quaternion types have symbol tables, they are not
really structs, so set the meta type to "none", allowing the types to be
encoded correctly.

cefe7e2e94 Use the correct source of defs for field defs. 2011-03-21 17:07:40 +09:00

0c0f4360da Make field defs "nosave". 
The engine treats fielddefs with DEF_SAVEGLOBAL set as bogus.

a919e5f619 Make class_check_ivars() use class_add_ivars() to add the ivars. 
This avoids implementation ivar blocks trashing the ivar offsets in
derived classes.

2464a89d37 Preserve relocs across def churning. 
Freeing then re-allocating a def to change its storage from external is
really not the right way to do it, but for now this fixes the loss of the
relocs. With this, the menus seem to work :)

7c770b75c5 Do not creat field defs for local storage.

defs.

7198be5726 Treat entities a bit like structures in field_expr (). 
Look in the entity field symbol table for the field before looking in the
normal symbol table. This allows entity fields to be accessed even when
the current scope has symbol of the same name. However, checking the
normal symbol table where there is no such field allows for field
variables when I get around to implementing them.

505bde308e Fix the handling of @system defs. 
When treating a def as external, actually say it is external.
