9a96febdf5 Fix the hordes of bogus defs. 
They were caused by unused external defs, so not processing unused externs
in the first place is the simplest solution.

Bill Currie
54317965cc Handle relocs. 
With this, the building of the work qfo seems to be almost finished, just
the special defs to go. Next step will be to stitch all the parts of the
work qfo into a real qfo.

However, still have to fix the relocs for the type descriptors, but they
are not critical to the linker's functioning.

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.
 2011-03-01 08:48:58 +09:00

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.

Bill Currie
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 :)

ea3895805b Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage. 
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.

emit.c has been gutted in the spirit of "throw one away".

There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.

		support -L libpath and setup the default include and lib paths

ece9660099 get @system working (Closes: #52). I'm not happy with the name of this 
operator and I'm very open to suggestions, but it seems to work. What
@system does is to mark a def in such a way that the linker will allow it
to be redefined /once/ giving the programmer control over where and when
a def is defined, but initializing it elsewhere. This is most useful when
working with v6 progs and separate compliation as the `system' defs need to
be in a certain order in certain locations or the resuting progs.dat file
will be incompatable with non-qf 0.5 servers.
