59b04dbcca Make many qfo int fields unsigned.
I don't remember why I thought signed was a good idea, but unsigned does
make more sense for most fields.

7a504f8983 Use float for enum defs in v6 progs.
The values are (or should be!) written as floats, so don't give any
debuggers hernias when displaying enums in v6 progs.

6eb6b6c0ba Change pointer_t to unsigned and clean up the mess.
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

d8a5d6745f Add a param flag to defs.
It is necessary to know if a def is a function parameter so it can be
treated as initialized by the flow analyzer. The support for the flag in
object files is, at this stage, purely for debugging purposes.

9691b50f0f Make .type_encodings more useful.
Rather than just a pointer, it is now a struct with a pointer and size
indicating the extent of the type encodings block.

eb5581c7bd Fix class type encoding.
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.

4ef4711c3b Make the type encodings findable.
The base of the type encodings block is given by the .type_encodings def.
The block begins with a "null" type (4 words of 0), followed by the first
type encoding.

At some stage, I will need to add information for extended def information
(32 bit offset, type encoding, other?), but this is good for initial
testing.

02a70ebe1c Remove the auxfunction manipulation from the compiler proper.
It was broken code in the first place (realloc and pointers), and is
redundant with the new linking process.

66447df6b3 Undo the offset relocation of local defs.
The debug info expects local defs to be 0 based, so once relocations in
the progs data have been completed, undo the local def offset relocation
so that the correct offsets will be written to the debug info.

535dfad305 Emit defs for far data.
They will break when the offsets exceed 64k, but they are needed for
debugging.

97b1ceceb0 Fix line number info.
line number info is now 1 based rather than 0 based (to better detect when
a function does not have line number info).

4a99f8dcbd Write the linker output to progs.dat.
There is much breakage, but qfcc now produces a progs.dat from either
progs.src or object files. Better yet, the progs.src result is passed
through the linker, removing much duplicate code.
2011-03-02 20:51:00 +09:00

ecb995a8f7 Rewrite qfo_to_progs() to go direct from qfo to progs.dat.

This is mostly redundant, but it allows qfo spaces to get out of order
without breaking everything.

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 :)

afc5b2827d Simplify def handling, use far data.
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.

Also, start using far data for ObjQC structures.

The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

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.
