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
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
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
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.
2011-02-18 09:03:04 +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
d04865884f
Set the method's function pointer.
2011-02-15 22:27:13 +09:00
3721b2edca
Method lists are made of methods, not integers :P
2011-02-15 22:26:44 +09:00
c068138d91
More addresses in hex.
2011-02-15 22:26:09 +09:00
814e36d3c8
Correct an error message and tidy some code.
2011-02-15 22:25:40 +09:00
57f735c99c
Avoid another segfault when debugging.
2011-02-15 15:33:18 +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
5252d72856
Correct the type for _OBJ_SELECTOR_TABLE.
2011-02-15 15:33:12 +09:00
b3da6ef3d4
Allow zero size arrays to match sized arrays of the same type.
...
This allows externally declared arrays to not specify a size.
2011-02-15 12:08:03 +09:00
b2d4aee61e
Reimplement selector expressions to work with far data.
...
They currently execute a lea instruction every method call, but the
optimizer should take care of that once its written.
2011-02-15 10:48:05 +09:00
6bd63f811f
Preserve any relocs when converting a def from extern to otherwise.
2011-02-15 10:47:16 +09:00
62456dc1e9
Yet another test.
2011-02-15 09:48:10 +09:00
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
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
bc882ddc3c
Fix the parser side of aggregate initializers.
2011-02-14 23:31:37 +09:00
09af401f0c
Reset current_func at the end of each function.
2011-02-14 23:10:46 +09:00
3a1e467ae8
Non-bogus syntax and warning fixes for ruamoko/cl_menu.
...
Sadly, there are many bogus warnings and other errors. qfcc is still very
sick :(.
2011-02-14 23:10:46 +09:00
9ac6929cf7
Syntax fixes for ruamoko/game.
...
This one actually would compile if object files were working.
2011-02-14 23:10:46 +09:00
6af747705c
Syntax fixes for ruamoko/scheme.
2011-02-14 23:10:46 +09:00
da3ac388fe
Syntax fixes for ruamoko/gui.
...
Once aggregate initializers are working, ruamoko/gui will "compile"
(no object files, and still the bogus integer constant into ... warning).
2011-02-14 23:10:46 +09:00
5fa349927f
Preserve the ivars inheritance chain across build_struct().
...
build_struct() unlinks the structure symbol table from its parent, but
that breaks the ivar inheritance chain.
2011-02-14 23:10:46 +09:00
5707888fcf
Fix some error-recovery segfaults.
2011-02-14 23:10:46 +09:00
f1fccb19dd
Allow same-type re-declarations of uninitialized variables.
...
This is especially important for declaring variables that were previously
declared external.
2011-02-14 23:10:46 +09:00
b3d5789377
More tests.
2011-02-14 23:10:46 +09:00
23b01be214
Handle invalid initializers gracefully.
2011-02-14 23:10:46 +09:00
4c63a0bad6
Generate a warning when creating a var with no type.
...
This makes the internal error in new_def() non-functional, but the warning
will catch the bug and there's no harm in leaving the test in new_def().
2011-02-14 23:10:46 +09:00
ee866ae3a6
Enable the small struct optimization.
...
For now, anyway. It would probably be much better to handle this sort of
thing in the optimizer stage.
2011-02-14 23:10:45 +09:00
bcaf3687c5
Fix loading structs into params via an offset pointer.
...
For certain values of "fix" :/. The code is ugly, but it does the right
thing: calculate the effect address and use the resulting pointer in a
move instruction.
2011-02-14 23:10:45 +09:00
352be1f8bd
Handle null string pointers.
2011-02-14 23:10:45 +09:00
e10d561459
Treat small structs as integers (disabled).
...
This is more to stash away a potential optimization. I need to fix the
real problem first.
2011-02-14 23:10:45 +09:00
6b29568fa9
Set the source file and line when copying an expression.
...
This fixes the crazy line numbers in the debug info.
2011-02-14 23:10:45 +09:00
52010b8f7b
Do not segfault with bogus debug info.
2011-02-14 23:10:45 +09:00
fc18ebd923
Add the source line number to most node labels.
2011-02-14 23:10:45 +09:00
3e5989463f
Update the def_tail when removing the last def from the space.
2011-02-14 23:10:45 +09:00
11485556e5
Quote expression names to avoid problems with null pointers.
2011-02-14 23:10:45 +09:00
c139099294
Put another bandaid on the type creation system.
...
It seems that building types is very fragile: all too easy to fix things
in one place and break something somewhere else. I guess the type system
will need a comlete rewrite at some stage.
2011-02-14 23:10:45 +09:00
e3325b199e
More tests.
2011-02-14 23:10:45 +09:00
595019d86e
Fix some problems found by the new qfcc.
...
With this, ruamoko/lib almost compiles (though no object files are output).
Just some bogus "redeclared" errors and an improperly implemented
statement that produces an ice.
2011-02-14 23:10:45 +09:00
daae0284a1
Work around a warning about passing int constants into ...
...
I'm not sure why this is happening now when it didn't in the old qfcc,
but this will take care of the warning for now until I can get around to
fixing it.
2011-02-14 23:10:45 +09:00
1195df9686
Update for the new syntax.
2011-02-13 21:25:36 +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
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().
