edd381931e Create obj_object after obj_class. 
obj_class is self-referential,but obj_object refers to obj_class. This gets
obj_class encoded properly.

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
ee28f3869c Fix the checking for assignments between id and Class. 
With Class now being struct obj_class rather than an actual class or
object, checking for Class now needs to be explicit.

Bill Currie
694b268f53 Correct the type of id. 
It should be struct obj_object * rather than Object *.

35a88d873c Rework the builtin class creation once again. 
Now the classes are built "properly" (using the same tools as the parser
itself), and the structs (obj_object, obj_class and obj_protocol) are built
separately, but using the class ivars.
 2012-11-11 16:23:04 +09:00
Bill Currie
b36bd3a988 Remove the list offsets from the class ivars. 
Even just before, type_obj_object, type_obj_class and type_obj_protocol
were a bit bogus (still are), but now the arrays used to list their ivars
are correct. I plan to create the above mentioned types using
class_to_struct to do it properly.

0cf16ac558 Make _OBJ_CLASS_foo the correct type. 
It needs to be type_obj_class, but I had gotten confused earlier when
rearranging the type names as I was having trouble with "not a class"
errors.
 2012-11-10 13:45:38 +09:00
Bill Currie
06fd912a09 Make super_class for the internal Protocol and Class objects. 
They're based on Object, and that needs to be represented properly.

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.

d33d062bd1 Rearrange class_message_response. 
Even if an object doesn't seem to respond to a message, return the message
so unrelated warnings or errors don't occur.

fd8c639773 Initialize current_symtab early, with pr.symtab. 
This (with the previous commit) fixes the problems with the tags for
builtin structs.
 2012-11-09 14:37:28 +09:00
Bill Currie
9cb0ca6fed Catch symtab operations with an invalid symtab. 
Just via a simple segfault, but it's better than silently missing incorrect
usage.
 2012-11-09 14:36:19 +09:00
Bill Currie
49cc4fed0c Give the builtin structures proper tags. 
With the previous commit, the structures were being created before a valid
source file name was available and thus qfcc would segfault when trying to
generate a tag. Now, the tags look better anyway :).

9fd8741b4f Move the state clearing into InitData. 
Now, for each compilation, or before linking, only InitData needs to be
called. Fixes the double chaining internal error when compiling and linking
in the same command.

f307c7bebc Rework the unary_expr grammar to allow ++*foo. 
This required throwing out the primary rules that snax did up to help me
with conflicts many years ago, but they were now getting in the way. Now
the productions from primary are merged in with unary_expr.

6ff2644ab5 Fix simple pointer dereferences. 
It turns out no code was being generated for x = *y. Ouch. I suspect I need
to take a better look at expr_deref at some time in the not too distant
future.

9095e1eabc Rework build_switch to use initialize_def. 
This required support for label reference expressions, whose purpose is to
represent the address of a label.

afbab60c25 Create linker_find_def. 
It turns out I didn't need it, but it could be useful in the future, so
I'll leave it in.

4ef4711c3b Make the type encodings findable. 
The base of the type encodings block is given by the .type_encodings def.
The block begins with a "null" type (4 words of 0), followed by the first
type encoding.

At some stage, I will need to add information for extended def information
(32 bit offset, type encoding, other?), but this is good for initial
testing.

7e293a38e8 Check for double-chaining of types. 
Chaining a type twice will form a loop in the type list, causing find_type
to go into an infinite loop.

950a3aa83d Avoid infinite recursion when encoding struct types. 
Structures (especially hard-coded ones) can be really nasty as they can
refer to themselves. Avoid the recursion by setting the type_def field of
the type before doing the recursive encodings in the structure encoder.
 2012-11-08 17:06:38 +09:00

7a25283beb Clear out the type encoding def from all types. 
The encodings of static types were getting corrupted because their defs
were not necessarily in the same places between compilations when compiling
multiple files.

5530e84ada Call find_type for pascal functions/procedures. 
The result of parse_params needs to be passed through find_type before

for qc.

f14d8060e0 Merge qfpc into qfcc. 
Since gnu bison and flex are required anyway, no harm in using their api
prefix options. Now, qfcc can compile both QC/Ruamoko and Pascal files
(Pascal is (currently?) NOT supported in progs.src mode), selecting the
language based on the extension: .r, .qc and .c select QC/Ruamoko, .pas and
.p select Pascal, while anything else is treated as an object file (as
before).

55ecf94f2d Don't draw arrows leaving return statements. 
Return statements never flow to the next block (or any other block, for
that matter), so drawing arrows leaving them not only messes up dot's
graphs, but is quite missleading.

56410ddc58 Prevent merged if/goto losing its way. 
When mering if/goto (ie, if skipping a goto), the rest of the dead code
remover is used to delete the goto. That part of the code unuses the goto's
label. The if was getting the goto's label without the lable's used count
being incremented (the usaged temporarily increases by one). I have no idea
why the problem showed up randomly, but this seems to fix it (it fixes /a/
bug, anyway).

75aa28cfac Mark all subsequent blocks as reachable after if/goto merge. 
If an if/goto merge is done in the first dead block pass, no blocks after
the merge have their rechable flag set because they've never been tested.

Bill Currie
8ddd58f951 Fix the dropping of the block after the merged if/goto. 
The naive implementation of the if/goto merging was letting the old target
of the if get dropped because the block would lose its label and thus be
judged unreachable because the preceeding goto block was still in the list.
Instead, when the if/goto are "merged", mark the goto block as unreachable,
the following block as reachable, and break out of the analysis loop to
force the removal of the goto block. Since the dead block removal function
loops until no action is taken, all other dead blocks will be removed.

e866619de6 Output basic block flow diagrams to files. 
The output can be controlled via --block-dot (not yet documented). The
files a named <sourcefile>.<function>.<stage>.dot. Currently, stage will be
one of "initial" (after expression to statement conversion), "thread"
(after jump threading), "dead" (after dead block removal), "final" (final
state before actual code emission).

ab73a267cd Do not unconditionally remove labels from blocks. 
Labels can be shared between multiple flow-control instructions, so use the

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.
 2012-05-03 13:57:31 +09:00
Bill Currie
006882407d Fix the source of alias def chains. 
The actual bug might still be elsewhere, but at least now I know the alias
chains were coming from accessing .return and .param_N, which are unions
(not directly usable by the progs engine). Emitting a reference to a union
(or struct) would create an alias def, but an alias expression was created
in the expression tree to simplify return/param access. The double layer
(sometimes 3 or 4) alias isn't really neaded, so rather than layering the
aliases, just re-alias the alaised def.

c8163fc0de Add an option to prevent the use of default paths. 
Despair has things locked down such that running qfcc during a build fails
due to lack of read access to /usr/local/lib. This is actually a good
thing as accidentally hitting old includes/libs (when a file gets deleted
in the tree) hides bugs. Thus, --no-default-paths to turn off default
search paths.

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. :)

55cc0f9206 Bring back the unsigned type (PROGS version bump) 
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

b522853765 Ensure the target of def_op relocs gets updated.

Look in the entity field symbol table for the field before looking in the

normal symbol table where there is no such field allows for field
variables when I get around to implementing them.
