cb366dd825 Better flow dot dump "scripting".
Not sure I want to keep the statements in the live dump, but the system
is more flexible now.

0f279cd3f0 Add a comment about fake statement numbers.
I had forgotten how they worked (not surprising after 6 years).

5ba13d759b Fix a FIXME.
Set of everything got added shortly after that FIXME was added, but I
forgot to fix it.

5dbb7b6d4d Handle all modelgen commands.
Just in case someone ever adds models.qc to progs.src.

027e76b4c9 Add a doc block to parse_cpp_line.
It took me too long to figure it out :P

Forgot to check if the test expression was not an error.

bf40f0126e Convert vector expressions when passing parameters.
Calling a function with [vector stuff] caused an ICE.

431074d58f Update label destination when moving labels.
This fixes a segfault when optimizing the empty-body test. The label was
getting moved, but the statement block to which it pointed was not updated
and thus it pointed to dead data.

d54ee6c8c3 Do not promote debug messages to warnings.
I think I copied the notice code for debug and forgot to edit the
promotion. Oops.

c88d1987a1 Add warnings for empty blocks in if/else/do.
Saw a discussion of such in #qc and that gcc implemented it. I realized it
would be pretty easy to detect and very useful (I've made such mistakes at
times).

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.

ec98954dfc Remove the small struct optimization.
It might cause trouble for the binary_expr() cleanup.

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

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.
2013-09-27 23:15:57 +09:00
Bill Currie
2572811bf4 Add support for quaternion.w/x/y/z.
It's sometimes more useful to have direct access to each individual
component of the imaginary part of the quaternion, and then for
consistency, alias w and s.

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.

Yay for continually improving gcc warnings :)

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.

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.

77337e2402 Separate "" and nil.
It turns out this is required for compatibility with qcc (and C, really).
Once string to boolean conversions are sorted out completely (not that
simple as qcc is inconsistent with if (string) vs if (!string)), Qgets can
be implemented :)

fd1ea9e00e Add an option to control the enum switch warning. 2013-06-26 09:29:37 +09:00

29df4ac7ee Fix case label lookup.
It looks like I had forgotten that the compare function is supposed to
return true/false (unlike memcmp's sorting ability). Also, avoid the
pointers in the value struct as they can change without notice.

Using enums in switches now works nicely, including warnings for unused
enum values.
2013-06-26 09:29:31 +09:00
Bill Currie
8ac2c3a04d Check for unused enum values in switch statements.
Unfortunately, it turns out the value lookup is broken (including for
duplicate cases).

35bc981402 Allow use of a jump table when switching on an enum. 2013-06-26 09:25:45 +09:00

64f76bd762 Use the right value when getting a function's defref.
Either I had gotten confused while writing the code and mixed up line and
offset, or I had changed offset to line at one stage but missed a place.
This fixes the segfault when compiling chewed-alias.r and return-ivar.r

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.

9d418379bf Use the correct type when allocating flow node edges.
sizeof (struct) vs sizeof (struct *). Ouch.

6a3c775270 Correct the emission of meta class ivars.
type_obj_class is no longer a class, so its ivars are not stored in
type_obj_class.t.class->ivars but rather type_obj_class.t.symtab.

This fixes the segfault Spirit and Randy were experiencing.

In passing, correct the unneeded emission of meta class ivars for non-root
classes. This should make for much smaller progs that use classes.

e27d7cbd2d Handle alloca "correctly".
Use AC_FUNC_ALLOCA and the #ifdef mess suggested by the autoconf docs
(hidden in qfalloca.h).

f1aefc969d Fix some 64-bit mingw compile issues.
Just one more issue to fix (alloca), but with a hack, QF compiles (no clue
yet if it works: wine doesn't seem to be an option at this stage)

eacc59c016 Build the field types array for enums, too.
However, every element is the same: type_default's type_def. This fixes the
segfault building qwaq introduced by the previous enum commit.

46d2959908 Delay calling find_type for enums.
As find_type encodes the type too, calling find_type before the enumerators
have been created causes the type encoding to lose the enumerators.

7a504f8983 Use float for enum defs in v6 progs.
The values are (or should be!) written as floats, so don't give any
debuggers hernias when displaying enums in v6 progs.
