2cb1c74718 More progress on the linker.
Need to finish up defs and handle relocs, and then take care of special
defs (@self etc), but things are getting very close.

21558864b9 Make defrefs a little more stupid.
Stupid code does little well :P

I forgot that spaces get realloced, and I don't remember why I had the def
list pointer separate anyway.

1837518d05 Split the space processing into two passes.
This allows strings and types to be handled before code and data.

eb11a19ed4 Split the type processing into two passes.
This allows all duplicate types to be "merged" before adding any new
types, thus avoiding any accidental duplication caused by possible
differences in order between defs and the type descriptors.

3761cddca6 Finally, some real progress on the linker.
There is still much to be done, but this seems to be a workable approach.

bad7078797 Don't set the space defs pointer if there are no defs. 2011-02-28 23:16:59 +09:00
Bill Currie
5d9fbc2d6d Set the space ids to the destination space.
This is mostly redundant, but it allows qfo spaces to get out of order
without breaking everything.

c8f1b5b1f0 Fix the missing type encoding for structures.
There should be a better way (probably by doing the encoding as needed
rather than in chain_type), but this seems to work for now.

438d14d852 More or less fix qfprogs when dumping info from qfo files.
Relocations are still broken, but everything seems to be working and
qfprogs now seems to be generally usable.

Very important for distinguishing them from other types.

a106c1fb51 Add a field for loose relocation records.
Loose relocation records are those that are not bound to a def or a

66b255afbf First stage of the linker rewrite.
Strings, code and data spaces are "merged". Various offsets are updated.
Still to do:
 o  Merge reloc, def, function and line data.
 o  Merge type data.
 o  Update def and function type pointers.
 o  Resolve external defs and check for duplicate defs.
 o  Perform relocations.
 o  anything else I've forgotten :)

c585a17db9 Give type data a null pointer.
Pointers to the void type descriptor looked just like null pointers and
that was terribly confusing. Avoid that confusion by pre-allocating a
small amount of data in order to reserve space for a null descriptor.

b50b392746 Fix field def allocation for function fields.
Assignment of nil to a field function is permitted, but trying to use one
as a builtin or as a normal function is treated as an error.
.void (float y) func;       OK
.void (float y) bi = #0;    error
.void (float y) ni = nil;   OK
.void (float y) co = { };   error
