Bill Currie 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.

Bill Currie 7a2f7e8982 Add some safety checks to progs global dumping. 
Getting segfaults in the debug tools is not fun :P

Bill Currie cc24e2e67e Initialize global string vars correctly. 
Ouch, I'd fixed that for arrays, but not normal vars.
 2012-11-09 12:23:04 +09:00
Bill Currie 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.
 2012-11-09 12:22:34 +09:00
Bill Currie 48fe9f729d Add partial support for pointer arithmetic. 
Only pointer +/- integral is supported. pointer - pointer will come later.
 2012-11-09 12:21:45 +09:00
Bill Currie 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.
 2012-11-09 11:57:06 +09:00
Bill Currie 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.

Bill Currie 1d060d1ac1 Quote string values when dumping globals. 
Much nicer :)
 2012-11-08 21:13:24 +09:00
Bill Currie eb86a66ce5 Do some class object type renaming. 
type_object -> type_obj_object
type_Class -> type_obj_class
type_ClassPtr -> type_Class

In the process, one more FIXME is gone :)
 2012-11-08 20:58:48 +09:00
Bill Currie 377f8f9d56 Use an explicit flag for class initialization. 
Much cleaner than messing with class_Class, which is about to go away.
 2012-11-08 17:14:33 +09:00
Bill Currie 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.
 2012-11-08 17:14:33 +09:00
Bill Currie 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
Bill Currie 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.
 2012-11-08 17:06:38 +09:00
Bill Currie a3a22f2a1b Add the ability to dump qfo type encoding. 2012-11-08 17:06:38 +09:00
Bill Currie 09d1cd61f3 Don't convert a qfo to progs unnecessarily. 
This avoids segfaults on reloctions for external defs.
 2012-11-08 17:06:29 +09:00
Bill Currie 61ef901254 Tweak some FIXMEs. 2012-11-08 17:03:02 +09:00
Bill Currie ed4018fd8d Clear out the function overloading tables between compiles. 
Fixes some issues with multiple compiles (especially mixed languages!).
 2012-11-01 20:53:33 +09:00
Bill Currie ea34a5b753 Fix some nasty memory errors. 
Three cheers for valgrind!!!
 2012-11-01 20:53:28 +09:00
Bill Currie 5c79953a7e Put quotes around strings for statement operands. 
This makes reading output a bit easier (especially if the string is empty
or just whitespace).
 2012-10-30 12:31:28 +09:00
Bill Currie f8bdd909cc Separate out C and html quoting into separate functions. 
Dot sometimes wants normal C quotes, othertimes html. Quite annoying,
really, but this is cleaner anyway.
 2012-10-30 12:31:22 +09:00
Bill Currie f680521e0f Escape unprintable chars. 2012-10-27 11:45:51 +09:00
Bill Currie ec42bde527 Make hash tables more const correct. 
And clean up the resulting mess :/
 2012-10-27 11:44:31 +09:00
Bill Currie 034139b806 Move some code around so it's more accessible. 2012-10-27 11:43:29 +09:00
Bill Currie 7519ec7bbd Fix the bogus missing return warning. 
Pascal's return mechanism is such that void return is always used.
 2012-10-26 20:11:38 +09:00
Bill Currie 3f351a5c88 Fix a printf format goof. 
Forgot to compile test :/
 2012-10-26 19:38:59 +09:00
Bill Currie 52b9721027 Add the COMMA token to the pascal parser. 
I guess I forgot I needed to keep token numbers in sync between pascal and
qc/ruamoko.
 2012-10-26 19:06:10 +09:00
Bill Currie 72045f1a5b Delay storage setting for pascal functions. 
The function def must not be local. This fixes the null function call in
gcd.pas.
 2012-10-26 19:03:00 +09:00
Bill Currie 27b83a8d65 Clean up all extra aborts, using internal_error instead. 
Some internal_error calls have no message, but at least things will be more
consistent.
 2012-10-26 19:02:02 +09:00
Bill Currie 5530e84ada Call find_type for pascal functions/procedures. 
The result of parse_params needs to be passed through find_type before
actually being used. I guess I'd missed this back when I got things working
for qc.
 2012-10-26 16:20:57 +09:00
Bill Currie 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).
 2012-10-26 16:01:41 +09:00
Bill Currie 358ea4ef9a Fall back to execve/wait when execvp and waitpid are unavailable. 2012-08-19 13:18:38 +09:00
Bill Currie b6125276e4 Fix the mis-handling of the progs.dat line in preprogs.src 
Gah, must have lost a line at some stage. Also, handle line number
directives.
 2012-07-14 19:01:47 +09:00
Bill Currie 7444371162 Disable bolding for special chars. 
If an escape sequence is used to access a char, the the programmer probably
wanted that char, regardless of the current bolding mode.
 2012-07-14 17:47:34 +09:00
Bill Currie 3b8141691e Fix a bunch of continue vs break issues. 2012-07-14 17:26:13 +09:00
Bill Currie 1364bff91b Add an extended mode to qfcc. 
Extended mode allows extra keywords (switch, for, etc) that are compatible
with v6 progs.
 2012-07-14 17:16:33 +09:00
Bill Currie 4055d9a435 Add support for \s escapes to qfcc. 
I guess \s is an fteqcc extention for toggling bold characters. At the
request of freewill.
 2012-07-14 11:47:26 +09:00
Bill Currie dbc203b625 And a few more bits of whitespace. 2012-05-23 08:21:27 +09:00
Bill Currie 23a38738fc Massive whitespace cleanup. 
Lots of trailing whitespace and otherwise blank lines.
 2012-05-22 08:23:22 +09:00
Bill Currie 0036a5e113 Ensure edict_size is never 0. 
Avoids division by / in NUM_FOR_EDICT
 2012-05-06 21:35:42 +09:00
Bill Currie 1dd5cccda2 Correct some more error messages. 2012-05-06 18:52:05 +09:00
Bill Currie a0788c6cdf Implement constant folding for unary operators. 
Including conversions between float and int :)
 2012-05-06 18:49:07 +09:00
Bill Currie f781e9078c Correct some typos in error messages. 2012-05-06 18:43:18 +09:00
Bill Currie 954e03c3f7 Report the correct function name for the largest locals. 
I must have been tired when I adapted that code.

Bill Currie 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.
 2012-05-05 18:04:10 +09:00
Bill Currie 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).
 2012-05-04 22:35:20 +09:00
Bill Currie 953e789db2 Handle movement of the final block. 
Moving a final block caused segfaults and weird flow graph corruptions.
 2012-05-04 19:48:32 +09:00
Bill Currie e8c17c68e6 Fix a segfault when the switch expression errors. 2012-05-04 18:13:11 +09:00
Bill Currie 5df25133b3 Implement code movement for unconditional jumps. 
That is, when the destination of the jump is reachable via only the jump.
 2012-05-04 18:00:05 +09:00
Bill Currie 33bfac0508 Process all basic blocks for jump threading. 
I'd copied the for loop from the dead block removal code, but jump
threading doesn't need to look at the following block...
 2012-05-04 14:10:30 +09:00
Bill Currie f169a7732d Factor out label unuse. 
I expect to need this more often in the future.
