29985efcef Expose some linker functions to the rest of the compiler.
They proved to be useful for cleaning up the final compilation stages.

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.

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.

1416b996d3 Ensure the type space pointer is cleared with each object file. 2011-03-01 09:18:09 +09:00

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.

05e6f00e72 Initialize the new type def.

3761cddca6 Finally, some real progress on the linker.

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.

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.
