05e6f00e72 Initialize the new type def. 
Oops :P

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.

4f6d18a328 Encode the basic type for functions, fields and pointers. 
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
function.

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

497db3ac81 Fix the return symbol extraction when appending a return statement. 
The code is still icky, though :P

4fd6bdae6f Allow nil to be assigned to field variables. 
Note, this is the field variable itself, not the field in the entity.
eg:
	.integer x = nil;

87b240f469 Use special treatment for .float ()foo; functions. 
The parser wants to treat .float () foo; as a function returning a float
field, but qcc treats it as a field holding a function variable.
Fortuantely, field types are always "simple" (ie, at worst, just more
field type wrappers around the non-field type), so all that's needed to
obtain qcc grammar is to reach into the field type layers and do the
function type calculation based on the non-field type found there.

bffc1dd239 Clean up objective-qc type encoding. 
Structures etc now never encode the fields as well (I might revert that
at some time). Type parsing has been removed: it has proven unnecessary
and overly complicated, and the new qfo encoding should be more useful.

41523852cd Cleaner def and string emittion for types. 
Use local defines for emitting defs and strings as everything goes to the
same locations.

7251bc91fa Enhanced type encoding. 
This creates a compact representation of types as seen by qfcc. This is
intended mainly for debuggers.

0f0ed3dae2 Allow null types in defs again. 
However, only at the lowest level. This is needed for my type encoding.
 2011-02-18 09:04:33 +09:00

ca6dd204b3 Use the right type for VM pointers. 
Probably more of these hiding in the code.

bceb98e5a4 Create structures for new qfo format. 
This breaks a lot of existing code, so that code has been commented out
for now.

Bill Currie
9c9a71f1af Allow defs to specify use of offset relocations. 
Access to struct fields in near data can be done using only one operand,
but offset relocs need to be used. However, as not all defs want offset
relocs, a flag has been added to the def struct.
