cd12a78f93 Replace some accidentally deleted code. 
Forgot to commit it the first time round, then rebase messed me up and I
didn't notice until after pushing. *sigh*

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.

2992d66f87 Simplify the tag used for anonymous structs etc. 
Hopefully two files with the same file name won't have anonymous stucts on
the same line.

4192ef835c Delay initialization of obj_module_t as long as possible. 
This keeps the type descriptor out of progs that never use any
Objective-QC features.

ee9045c377 Emit code for jump tables. 
With this, the entirety of the ruamoko tree builds (though the progs will
be broken in various ways: mostly unrelocated references).
 2011-03-03 19:09:00 +09:00
Bill Currie
a281033920 Alais the jump table's array to an integer. 
As per the previous commit, I'm not sure this is the right thing to do, but
it works for now.
 2011-03-03 19:07:37 +09:00

4324486ae6 Give - unary expressions special treatment. 
The progs engine has no neg instruction, so need to implement -val as
nil - val
 2011-03-03 18:13:30 +09:00

f9e177efd6 Obtain the label to be removed from the correct place. 
This fixes the undetected dead block after "if return else return".
 2011-03-03 17:50:46 +09:00
Bill Currie
ed901bd48f Drop unused labels rather than adding them to the statement block. 
However, even unused labels create a new statement block if necessary.
 2011-03-03 17:35:06 +09:00

That fixme was right :)
 2011-03-03 15:02:26 +09:00

610d775bd1 Treat void values as the largest type. 
This fixes passing nil through a structure return value.
 2011-03-03 14:56:21 +09:00

bad5fddec4 Fix overloaded function resolution. 
Update the expression symbol pointer, not just the symbol name.

74e6b13aee Use alias expressions where possible when testing an expression. 2011-03-03 13:47:28 +09:00
Bill Currie
d937172243 Create and use alias operands for alias expressions. 
This avoids the alias expression modifying the operand used in other
expressions.

022fde666f Implement unary expression statements. 2011-03-03 13:10:07 +09:00
Bill Currie
45de7327dc Implement alias expressions (finally). 
Alias expressions are like cast expressions, but never do any conversions.

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
Bill Currie
29985efcef Expose some linker functions to the rest of the compiler. 
They proved to be useful for cleaning up the final compilation stages.
 2011-03-02 20:48:55 +09:00
Bill Currie
8cdd28f534 Use qfo_to_progs() for dumping qfo data. 
Yay, less duplicate code, and better yet, qfo_to_progs gets some much
needed testing :).
 2011-03-02 19:08:11 +09:00
Bill Currie
ecb995a8f7 Rewrite qfo_to_progs() to go direct from qfo to progs.dat. 
Relocs and debug info is currently broken.
 2011-03-02 19:06:43 +09:00

fda46a4aca Handle the special defs. 2011-03-02 12:26:53 +09:00
Bill Currie
330e76a9ac Set the correct storage class for struct and enum specifiers. 2011-03-02 11:29:08 +09:00
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.
 2011-03-02 11:16:35 +09:00
Bill Currie
8669dc373f Add some documentation. 2011-03-02 11:13:44 +09:00
Bill Currie
65bd215058 Minor rearrangements. 2011-03-01 15:35:14 +09:00
Bill Currie
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.
 2011-03-01 15:18:47 +09:00

cfff2b1037 Add defs from near and far data spaces. 2011-03-01 10:52:27 +09:00
Bill Currie
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.
 2011-03-01 09:19:04 +09:00
Bill Currie
1416b996d3 Ensure the type space pointer is cleared with each object file. 2011-03-01 09:18:09 +09:00
Bill Currie
30272968c9 Update the def's type pointer. 2011-03-01 09:17:32 +09:00
Bill Currie
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
Bill Currie
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.
 2011-03-01 08:46:02 +09:00
Bill Currie
05e6f00e72 Initialize the new type def. 
Oops :P
 2011-03-01 08:16:14 +09:00
Bill Currie
3761cddca6 Finally, some real progress on the linker. 
There is still much to be done, but this seems to be a workable approach.
 2011-02-28 23:18:07 +09:00
Bill Currie
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.
 2011-02-28 23:16:19 +09:00
Bill Currie
b544196c21 Change ptrfld to fldptr for consistency with type.h. 2011-02-28 23:12:32 +09:00

8b661bbb89 Rename qfo_reloc_t's def to target and correct its usage. 2011-02-27 11:37:24 +09:00
Bill Currie
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.
 2011-02-27 00:39:40 +09:00
Bill Currie
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.
 2011-02-27 00:36:45 +09:00
Bill Currie
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

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 :)

a1ea492889 Remove some redundant fields from qfo objects. 2011-02-23 10:40:35 +09:00
Bill Currie
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.

Bill Currie
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
 2011-02-22 09:20:52 +09:00
Bill Currie
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;
 2011-02-22 09:19:01 +09:00
Bill Currie
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.
 2011-02-22 08:54:01 +09:00

4c11304c8d Documentation tweaks. 2011-02-21 08:41:03 +09:00
Bill Currie
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.
 2011-02-18 20:51:04 +09:00
Bill Currie
41523852cd Cleaner def and string emittion for types. 
Use local defines for emitting defs and strings as everything goes to the
same locations.
 2011-02-18 12:44:11 +09:00
Bill Currie
7251bc91fa Enhanced type encoding. 
This creates a compact representation of types as seen by qfcc. This is
intended mainly for debuggers.
 2011-02-18 09:06:05 +09:00
Bill Currie
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
Bill Currie
bceb98e5a4 Create structures for new qfo format. 
This breaks a lot of existing code, so that code has been commented out
for now.
 2011-02-17 15:02:09 +09:00
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.

4336fc2c73 Move method function defs into the far data space. 
As they are never referenced directly by instructions, there's no need for
them to be in the near data space, taking precious def locations.

4e86b28b59 Use the def type rather than expression type to select the init method. 
Local defs may be initialized with non-constant expressions, which
includes function calls. Both function calls and aggregate initializers
use block expressions.
 2011-02-15 09:38:44 +09:00

e0d61705b4 And fix build_struct for built-in struct types. 
The previous fix broke builtin structs (eg, @param). Calling find_type()
for built-in structs has proven to be a bad idea :)
 2011-02-13 21:07:22 +09:00
Bill Currie
a19b7ec8f9 Make struct decls actually work. 
find_type() does type comparisons based on tag name for struct/union/enum
but when it returns the previous tag (eg, from "struct foo;") the returned
type has a null symtab pointer, so setting the symtab pointer in the type
before calling find_type() only throws away the symtab. Thus, since
find_type() doesn't check the symtab pointer when comparing the types, set
the symtab pointer after calling find_type().

Bill Currie
d75c35ba30 Allow qc style function params. 
Due to ambiguities in the grammar, qc-style function params and c-style
function params had to be completely separated. This means that qc-style
functions can not use pointers and must use qc-style function declarations
for parameters, and c-style functions must use c-style param declarations.
While this rule is tedious for converting the Ruamoko library, it does
actually make for a more consistent language.

ac91e9376b The big type-system rewrite. Horribly broken :) 
While broken, it is good enough to compile modulo.r.

This gives qfcc C's type system with QC specifics bolted on top (rather
than trying to cram C's type system into QC's). Pointers and arrays now
use C syntax and semantics (though I think there's a lot of breakage in
there at the moment). Functions themselves are still dual mode: both QC
style and C style are available.

That which isn't rewritten is horribly broken. However, this does include a

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

code. Things should be a little more fun from here on.

very broken.

Don't emit the above if the last emitted statement is a return and there is
no label at the end of the function.

02b3dde83b Make QuakePascal programs runnable.

 2010-12-26 22:33:04 +09:00

2c84ae4898 Don't let casting in constfold increment users. 
This fixes Deek's temp notice. No new notices have shown up, so this should
be the correct fix. The constant folding code no longer calls cast_expr
directly, but rather uses an internal wrapper that decrements users after
cast_expr increments it, resulting in a no-op.

0e5cd14829 tactical whitespace bomb 
Add return-type information to all methods, split up lines properly where
I could find them, and ran the whole thing through uncrustify. Looks purty
now. :)

cdc79ae6f8 Add type information, don't return self most of the time 
Start "modernizing" the code base; old code is based heavily in the
Smalltalk style, where everything that doesn't return a different object
returns self. This can be useful, but it isn't what is usually done these
days. Also, add type information (which didn't exist in "the old days" --
an object was an "id", not a "Foo *") to help with debugging.

dbab1545e5 Comment an #if 0 
Looks like John Carmack was going to implement "reference" .qpr directories,
where they would contain a reference to the "real" base path, but never got
it finished. Make a note in the source to explain the "dead" code.
