Explicitly select between direct and indirect moves.

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.
2011-03-07 13:33:02 +09:00

Optionally create *_[xyz] symbols for accessing vector components.
...
"vector-components" in code options controls this feature. The default is
off for advanced code and on for traditional code. Disabling
vector-components prevents the comonent names polluting the namespace and
reduces the number of globals needed for vector fields if the components
of that field are never used.

Maintain a symbol table for entity fields.
2011-03-06 15:38:19 +09:00

Add is_float ().
...
For now, it checks just floats, but I might one day add doubles.
2011-03-06 11:35:15 +09:00

Add is_integral() to check for integral types (integer, short, enum).
2011-03-06 11:25:12 +09:00

Implement think expressions.
2011-03-05 18:01:37 +09:00

Perform the relocations!!!
...
line numbers seem to be broken, but the code itself looks good.
2011-03-05 08:41:14 +09:00

Make D_STRING() more useful and add D_GETSTR()

Generate the debug symbol file.
2011-03-04 18:46:05 +09:00
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.
2011-03-04 08:25:50 +09:00

Add the new header files for make dist.
2011-03-04 00:11:13 +09:00

Create and use alias operands for alias expressions.
...
This avoids the alias expression modifying the operand used in other
expressions.
2011-03-03 13:46:07 +09:00
45de7327dc
Implement alias expressions (finally).
...
Alias expressions are like cast expressions, but never do any conversions.
2011-03-03 11:06:10 +09:00
c12211d8bb
Support enum results for boolean expressions.
...
eg enum BOOL x = a && b;
2011-03-02 22:46:55 +09:00
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
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
ecb995a8f7
Rewrite qfo_to_progs() to go direct from qfo to progs.dat.

Relocs and debug info is currently broken.

Encode the basic type for functions, fields and pointers.
...
Very important for distinguishing them from other types.

Fix the QFO_POINTER macro

Add a field for loose relocation records.
...
Loose relocation records are those that are not bound to a def or a
function.

Rename new_defspace() and defspace_new_loc().

Write out object files in the new format.

More docs and clearer types.
2011-02-22 09:23:04 +09:00

Update qfo version and correct some comments and types.

Documentation tweaks.
2011-02-21 08:41:03 +09:00
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
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
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
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.
2011-02-15 22:55:15 +09:00
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.
2011-02-15 15:33:18 +09:00
19f6faf0ad
Fix aggregate initializers.
...
Initializing arrays and structs seems to be working.
2011-02-15 09:30:37 +09:00
d162838299
Resurrect constant_expr().
2011-02-15 09:28:27 +09:00
0b5565396b
Add a class type to symbols and rework the CLASS_NAME handling.
...
This fixes the problem with [Array alloc] producing a warning about Class
not repsonding to -alloc.
2011-02-13 16:05:09 +09:00
c4f364fd37
Emit pointers properly.
...
Rename ReuseConstant to emit_value and use emit_value to emit any non-short
constant. This fixes the null pointer in the call to __obj_exec_class.
2011-02-13 10:09:42 +09:00
181596f5bf
Make relocation records store the space of the relocation.
...
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.
2011-02-12 22:34:38 +09:00
cfdc2e5d6b
Complete the documentation for relocations.
...
This covers only in-memory storage of relocation records, not object file
relocations.
2011-02-12 15:55:58 +09:00
e19f7e3521
Sort out the parameters for QC style functions :)
2011-02-11 22:29:57 +09:00
01a7af17e5
Beat __obj_exec_class into submission.
2011-02-10 00:15:19 +09:00
d66a441867
Write out the far data space as well as the near.
...
This causes the Objective-QC structs to be emitted now that they havve been
moved to the far data space. Relocs are broken, though.
2011-02-09 21:45:29 +09:00
