Dot interprets escape sequences in non-html string, and needs the quotes to
be escaped, so quote the result of operand_string. Unfortunately,
operand_string uses quote_string and quote_string returns a static pointer,
so some hoop-jumping is necessary.
It seems the dag creation algorithm doesn't like "a = a op a", so use
"b = a op a" instead. Since I plan on fixing temp leaks anyway, this won't
be a problem (also, few people even use qfcc's v6 float modulo :P).
Because of the way it is used, the data in the type encodings space needs
to always be correct (ie, relocated), even for partially linked object
files.
Rather, only that it is neither external nor local. The idea was to catch
myself swapping the arguments to resolve_external_def, but for some reason
I decided type encoding defs would not be global (save game reasons?).
Fixes the bogus redefined errors when entity fields are used.
Also, rename extern_defs and defined_defs to extern_data_defs and
defined_data_defs (more consistent with the other tables).
The problem was caused by add_relocs and process_loose_relocs adjusting the
reloc offset based on the reloc's space's base address. This is fine for
most relocs, but as relocs for the type space have already been adjusted by
process_type_space, those relocs must be left alone by add_relocs and
process_loose_relocs. As a bonus, the duplicate code has been refactored
into a separate function :)
Now each encoding is copied across def by def using memcpy, with the
expectation that any references to other types will be handled via the
reloc system. Unfortunately, it seems there's an off-by-4 (hmm, suspicious
number...) in the reloc offsets, but I'll look into that after I get some
sleep.
defspace_alloc_loc can cause a realloc which will break the work qfo space
data pointers, so wrap it with alloc_data, which updates the appropriate
pointers and sizes.
The field/data def handling has been moved into process_data_def and
process_field def. The code for handling external defs has been moved into
its own function (extern_def()),
In passing, rename add_space to add_data_space, since it is limited to
handling data spaces.
For now, no other change has been made, but I'll be able to split up
process_def for data def vs field def processing and add a function for
processing type encoding defs.
First, the class def needed to be created before the class type, then the
def space indices had to be set early, otherwise the relocs wound up with
space 0 instead of the correct space.
All internal structs now have "proper" names, and fit the naming convention
(eg, obj_module (like objective-c's types, but obj instead of objc). Some
redundant types got removed (holdovers from before proper struct tag
handling).
Also, it has proven to be unnecessary to build internal classes, so
make_class and make_class_struct are gone, too.
When encoding a type to a qfo file, the type's encoding string is written
and thus needs to be valid prior to actually doing the encoding. The
problem occurs mostly in self-referential structs (particularly, obj_class)
because the struct is being encoded prior to the pointer to the struct.
