4bc40b3917 Rewrite binary_expr(). 
It is now in its own file and uses table lookups to check for valid type
and operator combinations, and also the resulting type of the expression.

This probably breaks multiple function calls in the one expression.

Bill Currie
3295370328 Expose and use field_expr(). 
This may cause problems later on, but it is needed for the binary_expr()
cleanup.

b66cbeeb57 Run fold_constants on comparison operands. 
This is a bit of a workaround to ensure the operands have their types
setup correctly. Really, binary_expr needs to handle expression types
properly.

This fixes the bogus error for comparing the result of pointer subtraction
with an integer.

c13f2c2c23 Fix the support for [s, v] for quaterions. 2013-09-27 23:15:57 +09:00
Bill Currie
7f50333b2c Add support for constant [] vector expressions. 2013-09-27 23:15:57 +09:00
Bill Currie
7a7a685105 Add support for actual vector expressions. 
Currently, they can represent either vectors or quaternions, and the
quaternions can be in either [s, v] form or [w, x, y, z] form.

Many things will not actual work yet as the vector expression needs to be
converted into the appropriate form for assigning the elements to the
components of the "vector" type.

a6cdc8735a Start implementing vec = [x,y,z]. 
This is a nice feature found in fteqcc (also a bit of a challenge from
Spike). Getting bison to accept the new expression required rewriting the
state expression grammar, so this is mostly for the state expression. A
test to ensure the state expression doesn't break is included.

35de42aeac Catch bogus comparison types. 
This fixes an ICE when trying to compare a function with a float.

cef2136050 Implement "not" logic for while and do-while. 
This goes towards complementing the "if not" logic extension. I need to
check if fteqcc supports "not" with "while" (the version I have access to
at the moment does not), and also whether it would be good  to support
"not" with "for", and if so, what form the syntax should take.

6fa63f6c54 Implement the basics of fteqcc's -Fifstring. 
It's -Cifstring in qfcc, but otherwise the intent is the same. More testing
and investigation into what fteqcc does is required.
 2013-06-26 23:02:55 +09:00
Bill Currie
8d34d33055 Implement "if not (foo)" syntax. 
It is syntactic sugar for if (!(foo)), but is useful for avoiding
inconsistencies between such things as if (string) and if (!string), even
though qcc can't parse if not (string). It also makes for easier to read
code when the logic in the condition is complex.

ca0b03687f Change the naming of ALLOC's free-list. 
Rather than prefixing free_ to the supplied name, suffix _freelist to the
supplied name. The biggest advantage of this is it allows the free-list to
be a structure member. It also cleans up the name-space a little.

9d27764576 Use new_binary_expr to recreate the assignment. 
assign_expr mangles the destination expression for dereferenced
assignments into something that is invalid as an lvalue, so simply use
new_binary_expr with the same opcode.

79519bc357 Avoid testing block expressions in truth assignments. 
This fixes the infinite loop in if ((x = self.heat && x))

Really, I think I need to revisit the whole expression tree code. It's
proving to be rather fragile.
 2012-12-24 20:01:16 +09:00

f6c4e06183 Reimplement assignment as truth value. 
The source of the assignment is used as the value to test, and the
assignment itself is inserted into the boolean expressions's block. This
fixes the inernal error for "if ((x = 0))".

f65ce22ddc Fold constants for the return value of test_expr. 
More constantness preservation.

22db05dc9c Alias value expressions by aliasing the value. 
This keeps constant expressions constant, even through aliasing.

b295524385 Add new_value_expr(). 
This simplifies creating a new expression for an arbitrary value object.

82ded2b638 Split the test for assignment and parenthesis.

aae0e21a5b Treat class instance access as a normal error. 
Normally, it will happen only as a follow-on error, but I can think of a
way to force it without other errors, so treating it as an internal error
is a bit harsh.
 2012-12-23 06:01:20 +09:00

452728126d Check the expression type when casting constants. 
Not all constant expressions are ex_value. This fixes the bogus errors and
ice in paroxysm.

3af031c33d Move the rest of the obj specific stuff into class.c. 
This gives better hiding of implementation details.

b9c5769e6d Allow messages to nil. 
That is, [nil message];. I just found out this is "perfectly legal"
(http://www.otierney.net/objective-c.html).

821081c9c8 Use the desination type for moves in assign_expr. 
for <struct> = nil; the source type is void and thus probably the wrong
size.

eb8fd55677 Move set.c into libQFutil. 
Also move the ALLOC/FREE macros from qfcc.h to QF/alloc.h (needed to for
set.c).

Both modules are more generally useful than just for qfcc (eg, set
builtins for ruamoko).

c06cd8fcc0 Cast constants at compile time. 
This takes care of the internal error due to aliasing values.

72108ba0b5 Document def.h. 
Also remove the extern for current_storage as it belongs in shared.h.

I'm not satisfied with the documentation for initialize_def, but it will do
for now. I probably have to rewrite the thing as it's a bit of a beast.

5725c5124c Rename the storage_class_t enum values. 
With the intoduction of the statement type enum came a prefix clash. As
"st" makes sense for "statement type", I decided that "storage class"
should be "sc". Although there haven't been any problems as of yet, I
decided it would be a good idea to clean up the clash now. It also helps
avoid confusion (I was a bit surprised after working with st_assign etc to
be reminded of st_extern etc).

984aa9a4cf Support entity.field = structvar2 = structvar1; 
The structvar2 = structvar1 is implemented as a move expresion, which
address_expr didn't like. Return the address of the source. For indirect
move expressions, this is just the source expression itself.

0cedf0d13a Fix a bunch of mis-uses of an expressions's value.

28ce35f1c1 Make values independent objects. 
values are now uniquely allocated (for the current object file). With
this, constants in dags will work.
 2012-11-15 13:44:06 +09:00
Bill Currie
aa72f263ec Use an extra temp for v6 float modulo. 
It seems the dag creation algorithm doesn't like "a = a op a", so use
"b = a op a" instead. Since I plan on fixing temp leaks anyway, this won't
be a problem (also, few people even use qfcc's v6 float modulo :P).

ee8247ec61 Support using enums as array indices. 2012-11-15 13:39:23 +09:00
Bill Currie
c96718493a A bit of a cleanup before fixing class type defs. 
All internal structs now have "proper" names, and fit the naming convention
(eg, obj_module (like objective-c's types, but obj instead of objc). Some
redundant types got removed (holdovers from before proper struct tag
handling).

Also, it has proven to be unnecessary to build internal classes, so
make_class and make_class_struct are gone, too.
 2012-11-12 11:12:33 +09:00
Bill Currie
96110a0f54 Treat messages to id and Class separately. 
As id and Class do not point to real objects as such, trying to get the
class from their types doesn't work, so instead send the message to a
"null" class that skips the method checks.
 2012-11-11 17:39:12 +09:00
Bill Currie
86091856be Revamp the static class creation. 
Type names are cleaned up, as is the creation. Also, the class pointer in
the type encoding now gets emitted. However, Still need to actually create
_OBJ_CLASS_Class and fix the type encoding reloc handling in the linker.

78a9ba2557 Make expression alias chains not-a-bug. 
The common cause seems to be casting a cast (very common, and I'm not sure
just realiasing the expression would be right). It does't cause any harm
(particularly, it doesn't trigger alias def chains), so I won't worry about
it.

6ead583195 Ruamoko: Implement infinity. 
The special token __INFINITY__, like __FILE__ and friends, will expand to
a floating-point expression containing a value the C compiler considers
infinite. Obviously, this assumes that the system has relatively modern
float hardware -- but if it doesn't, having Ruamoko be able to represent
float infinity is the least of your problems. :)

7198be5726 Treat entities a bit like structures in field_expr (). 
Look in the entity field symbol table for the field before looking in the
normal symbol table. This allows entity fields to be accessed even when
the current scope has symbol of the same name. However, checking the
normal symbol table where there is no such field allows for field
variables when I get around to implementing them.

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.

for when I rework emit.c after I do some reading.
