bf626c9e00 Fix some simple fixmes 2011-01-23 11:13:56 +09:00
Bill Currie
20b14af024 Add "is_math" type check and use for unary +/-. 2011-01-23 11:12:58 +09:00
Bill Currie
341f370662 Rename is_math() to is_math_op(). 2011-01-23 11:12:05 +09:00

dea6771d92 Create type_nil for passing nil into ... 2011-01-22 16:41:31 +09:00
Bill Currie
4ac80c2932 Get qfcc running again. 
It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)
 2011-01-22 15:52:57 +09:00
Bill Currie
55d3d17807 Add a missing break. 
"return" falling through to "goto" was bad news :)
 2011-01-22 15:52:01 +09:00
Bill Currie
d5f669af7a Nuke temp reference counting. 
The whole reason for this crazy developement branch :)
 2011-01-22 11:40:53 +09:00
Bill Currie
3b462e16cf Produce flow diagrams of the basic blocks. 2011-01-22 11:40:53 +09:00
Bill Currie
246778b5de Use function pointer tables instead of switch. 
This seems to be better for complicated code. switch seems to be better
suited for relatively simple code.
 2011-01-22 11:40:53 +09:00

2f09efe547 Break out print_expr into its own file. 2011-01-21 20:31:40 +09:00
Bill Currie
bcb2667b73 Possibly get vector calls working. 2011-01-21 19:40:46 +09:00
Bill Currie
52b561f7cb Nuke bind expressions. 
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).
 2011-01-21 19:07:58 +09:00
Bill Currie
0d01930056 Link a bool to its block rather than the block's head. 
This makes the flow make a little more sense.
 2011-01-21 18:50:17 +09:00
Bill Currie
977c48d728 Make operator type overrides clear. 2011-01-21 15:57:53 +09:00
Bill Currie
aec9f256a7 Get calls mostly working. 
Bind seems to be broken, but parameters seem to be being set correctly.
 2011-01-21 15:54:53 +09:00
Bill Currie
5c5fa67e43 Minor tweaks of the expression tree output. 2011-01-21 15:34:42 +09:00
Bill Currie
96fae582e3 Implement bind expressions. 2011-01-21 11:27:40 +09:00
Bill Currie
4a24393d8d Temp expressions now use operands instead of defs. 2011-01-21 11:26:43 +09:00
Bill Currie
2998e578fb Get very basic deref assignments working. 
More complicated expressions will not work yet.
 2011-01-21 10:59:16 +09:00
Bill Currie
ff6e2584da Handle block sub-expressions that produce results. 2011-01-21 10:57:47 +09:00
Bill Currie
16e013ff5d Allow the operand to override the symbol's type. 2011-01-21 10:56:32 +09:00
Bill Currie
3f2793ef72 Get a lot of statements being generated. 2011-01-20 23:26:13 +09:00
Bill Currie
e45ea4b2ae Move the statement printing near the top of the file. 2011-01-20 18:07:24 +09:00
Bill Currie
35b7278967 Re-disable the next-edge constraints. 
This gives a flatter layout.
 2011-01-20 15:36:10 +09:00
Bill Currie
08e387ebac Slight improvement to branch instruction nodes/labels. 2011-01-20 15:33:13 +09:00
Bill Currie
f8cc347dce Print expressions as dot files. 
While the resulting images can be a little confusing, they're much easier
to read than my cryptic postfix notation.
 2011-01-20 15:23:19 +09:00
Bill Currie
0594609b3a Get the label from the right expression. 2011-01-19 22:25:43 +09:00
Bill Currie
5deda9c9b9 Clean out ex_def as ex_symbol replaces it. 2011-01-19 22:25:04 +09:00
Bill Currie
b5424bca7d Start work on getting expressions converted to internal statements. 2011-01-19 15:47:45 +09:00
Bill Currie
cac2e04b18 Avoid namespace issues with dstatements. 2011-01-19 11:35:34 +09:00
Bill Currie
f2ef24d0cc Make symbols use the new value struct for constants. 2011-01-19 11:09:54 +09:00
Bill Currie
e08efe036b Move the constant expression values into their own struct. 2011-01-19 08:43:24 +09:00
Bill Currie
ff6e1b4d6c Get functions attempting to generate code. 
However, the statements are only printed as expressions.
 2011-01-19 08:38:09 +09:00
Bill Currie
87ce9f5333 Get basic function creation working. 
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.
 2011-01-18 12:47:13 +09:00
Bill Currie
8fb1b49a9d Add support for function symbols. 2011-01-18 10:46:42 +09:00
Bill Currie
b186173d18 Fix a segfault in structure finalization. 2011-01-18 08:59:44 +09:00
Bill Currie
21c0c960ae Initialize data before types. 
This is needed for string data. It might be better to init saved strings
separately, but this works for now.
 2011-01-18 08:58:43 +09:00
Bill Currie
3fe7a7250a Handle unnamed structures in make_structure. 
Symbols may not have null names.
 2011-01-18 08:56:47 +09:00
Bill Currie
b76a5c5284 Add my QuakePascal test program. 
Trivial as it is...
 2011-01-17 22:44:58 +09:00
Bill Currie
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.
 2011-01-17 22:34:41 +09:00
Bill Currie
85de101aa3 Break out the defspace code. 
This also makes some improvements to the free block handling code.
 2011-01-17 22:34:41 +09:00
Bill Currie
d3a98af783 Make internal_error globally available. 2011-01-17 22:34:41 +09:00
Bill Currie
537b930ba6 Add new_symbol_type to ease creation of typed symbols. 
This is inteded for code generation functions that need to create
variables and structures.
 2011-01-17 12:04:41 +09:00
Bill Currie
ffea505678 Cleanup QC's constant handling based on QP. 2011-01-14 12:10:28 +09:00
Bill Currie
c38ea0b1bc Correct the spelling of "nil". 2011-01-14 12:07:40 +09:00
Bill Currie
fb8b3d1211 Rework the lexer and parser to use symbols instead of defs. 
Currently parses the test program just fine, but code generation is very
very broken.
 2011-01-13 14:58:16 +09:00
Bill Currie
8f71986306 Add symbol expressions (like def expressions). 
They will eventually replace def expressions. Currently quite broken.
 2011-01-13 14:54:24 +09:00
Bill Currie
008f4e1929 Don't return .return in advanced mode. 2011-01-13 14:50:25 +09:00
Bill Currie
5b8725ca66 Rewrite the symbol (table) management in light of actual usage. 2011-01-13 14:48:38 +09:00
Bill Currie
ac14db7b1b Create a function to ease param list building. 
This is especially useful for QuakePascal, but it will mean I'll be able to
get rid of the parameter reversals in Ruamoko later on.
 2011-01-13 14:45:53 +09:00
Bill Currie
258c896e4d Create a function to build if/else blocks. 2011-01-13 14:33:16 +09:00
Bill Currie
638f4445cc More return code cleanup. 
Don't use the true void return in traditional mode.
Prefer the true void return over "done" at the end of functions.
Don't emit the above if the last emitted statement is a return and there is
no label at the end of the function.
 2011-01-13 00:46:46 +09:00
Bill Currie
3c9991364b Add a "void return" instruction. 
I got fed up with always having to explicty return something.
 2011-01-13 00:29:56 +09:00
Bill Currie
9ce9b70484 Add variadic functions. 
Already extending QuakePascal, and many basics aren't there yet :P
 2011-01-12 23:39:59 +09:00
Bill Currie
02b3dde83b Make QuakePascal programs runnable. 
Generate a mini-main function (".main", to avoid namespace pollution) that
calls the function named by "program", and make qwaq check for ".main" as
well as "main". If both are present, ".main" will take priority.
 2011-01-12 23:39:22 +09:00
Bill Currie
332b7da127 Minor header cleanup. 2011-01-12 23:34:15 +09:00
Bill Currie
96ba4605fa Fix the micro-optimization that avoided emitting x = x 
The check was broken by alias defs. If a def is aliased, the alias must be
checked.
 2011-01-12 23:33:51 +09:00
Bill Currie
c787923c99 Forgot to remove that print_expr. 2011-01-11 12:11:54 +09:00
Bill Currie
08bf7e24de Produce nicer code for post-op. 
The temp notice is still there for arrays (that's caused by issues in
constfold.c, not easily fixilbe), but it's harmless and correct (and nice)
code is much more important.
 2011-01-11 12:07:48 +09:00
Bill Currie
ad787ae98a Set the expression type to the correct value for addresses. 2011-01-11 12:06:40 +09:00
Bill Currie
21d7c78eb7 Allow deep copying of expression trees. 
Certain expression types (eg labels) are created fresh.
 2011-01-11 12:05:29 +09:00
Bill Currie
c73ac30e3f Turns out decrementing the users was very very bad. 2011-01-11 10:56:36 +09:00
Bill Currie
4af5dad424 More math identities. 
I forgot about 0 for multiplication and division. Detects division by zero.
 2011-01-11 08:49:43 +09:00
Bill Currie
5b43fc1de3 Improve interaction between temps and const_folding. 
Unfortunately, this seems to overdo the decrementing, so it could be
dangerous, but the ruamoko directory builds properly.
 2011-01-11 08:47:52 +09:00
Bill Currie
abe471110c Make inc/dec_users return the the expression. 
Just for convenience.
 2011-01-11 08:44:43 +09:00
Bill Currie
18ae178eaf Make new_vector_expr and new_quaternion_expr const-correct. 2011-01-11 08:43:34 +09:00
Bill Currie
4da2657bfe Fix most of the notice spam (hacky). 
The implementation and declaration of OP_DONE disagree (not sure what to do
about it yet), so give it special treatment when emitting.
 2011-01-11 08:07:04 +09:00
Bill Currie
ded741430b Add some missing static declarations. 2011-01-10 13:23:39 +09:00
Bill Currie
5f70e27613 Quaternions use quaternion_val, not vector_val :P 2011-01-10 13:23:12 +09:00
Bill Currie
cd38bd71fa Swap the order of scale and base for calculating the array index. 
fold_constants doesn't like dags very much, but it can do the right thing
if the expressions are in the right order. This is merely a workaround
until I get to work on the code generator itself.
 2011-01-10 12:26:11 +09:00
Bill Currie
5864c198cc Property list tests are working. 2011-01-10 12:26:11 +09:00
Bill Currie
d327c860cb Get messages working again. 2011-01-10 12:26:11 +09:00
Bill Currie
cb0bc7229a Resurect the debugging messages in rua_obj.c 
Yet another debug flag: SYS_RUA_OBJ
 2011-01-10 12:26:10 +09:00
Bill Currie
aac8185e4e Print some addresses in hex. 2011-01-10 12:25:31 +09:00
Bill Currie
6ebee4ad0e Get the type of Method right. 
It's a direct structure rather than a pointer.
 2011-01-10 12:25:31 +09:00
Bill Currie
ba27db6b93 Use some math identities to eliminate operations on non-constants. 2011-01-10 12:25:31 +09:00
Bill Currie
75ec6bf244 Clean out some unnecessary types from the progs engine and clean up the mess. 
This is a nasty commit, sorry, but 99% of the commit is interdependent.
 2011-01-10 12:25:31 +09:00
Bill Currie
c69ac1f56f Don't segfault when build_builtin_function detects an error. 2011-01-10 12:25:31 +09:00
Bill Currie
806d9110a2 Support both (* *) and // style comments. 2011-01-10 12:25:31 +09:00
Bill Currie
a17e73c863 Generate code. 
It's now time to work on the revamp of the symbols, trees, etc.
 2011-01-10 12:25:31 +09:00
Bill Currie
e34f7caeb0 Use op instead of integer_val for ADDOP etc. 2011-01-10 12:25:31 +09:00
Bill Currie
edaa6235e7 Get functions/procedures emitted. 
No actual code is emitted, though.
 2011-01-10 12:25:31 +09:00
Bill Currie
74016573b4 Need frame grabbing after all. 2011-01-10 12:25:31 +09:00

Bill Currie
25c36a51a8 -f and -F were reversed in the usage. 2011-01-10 12:25:31 +09:00
Bill Currie
fed82466cc The first stages of Quake-Pascal. 
At present, this parses a subset of the pascal language with a few type
extensions. There is already work on the type system.
 2011-01-10 12:25:31 +09:00
Bill Currie
ae4ca52661 Make function.h more independent. 2011-01-10 12:25:31 +09:00

782a4c9a8d New symbol table code. 2011-01-10 12:25:30 +09:00

dfbbda37af New tool: qflmp 
Stupid little lump tool, converts from lmp to pcx and back.

qflmp -h for help.

a27ea057c4 Add a test for calling class methods. 2011-01-03 18:11:46 +09:00
Bill Currie
02f78e46f8 More expression docs. 2011-01-03 16:25:59 +09:00
Bill Currie
5627e43465 Use the method's selector rather than its def name in error messages. 2011-01-03 16:25:29 +09:00
Bill Currie
a1f36a9944 Make new_function take a def rather than a name. 
Moves into new_function some code that should have been there in the first
place.
 2011-01-03 16:25:29 +09:00
Bill Currie
4c69a97ac7 Allow normal declarations within a class implementation. 
I had always been under the assumption that such was illegal in
Objective-C, but after working on Forge, I now know otherwise.
 2011-01-03 16:25:29 +09:00
Bill Currie
dc5bafb8fb Minimal error recovery. 
No more bailing on the first syntax error. While the recovery is not
perfect (things can get right twisted), qfcc will now continue parsing
after a syntax error.
 2011-01-03 16:25:29 +09:00
Bill Currie
a4635d79e8 Slightly more informative error locations. 
Inside a class or protocol definition is not "at top level" ;)
 2011-01-03 16:25:29 +09:00
Bill Currie
530e8fae34 Rework class_type_t to be more useful. 
This allows current_class to refer to procols as well (for error
reporting).
 2011-01-03 16:25:29 +09:00
Bill Currie
f738ef5dba Remove redundant RETURN statement rule. 
The same effect can be achieved with one rule using opt_expr.
 2011-01-03 16:19:28 +09:00
Bill Currie
58042719e5 A little more documentation for expressions. 2011-01-03 16:19:28 +09:00
Bill Currie
7946fec523 More cString cleanups. 
I don't know that fileSystemRepresentation is any better than cString for
general usage (due to wchar on windows).
 2010-12-28 07:42:08 +09:00
Bill Currie
d29e8deb0a Use Qprintf for writing maps, and fileSystemRepresentation to get the path. 2010-12-27 23:18:43 +09:00
Bill Currie
97e8ab7f3a A bunch more NSString and NSFileManager usage. 
It does make for cleaner could, though it would have been nice if NSData
was null terminated :P
 2010-12-26 22:33:04 +09:00
Bill Currie
8e13a8327d Use NSFileManager methods instead of access(). 
This even fixes a bug where an inaccessible bspSound was being opened.
 2010-12-26 21:07:55 +09:00
Bill Currie
f105fbd6a0 Use NS* classes for QUAKED directory scanning. 
The scanning of actual files is still done using normal C strings, but now
everything up to (but not including) opening the file is handled by *step.
 2010-12-26 20:45:01 +09:00
Bill Currie
232c67640c Get the QUAKED text for nullclass right. 
? is not a character that's lexed out by the script class.
This fixes the segfault when loading a map when no entities are defined
(ie, the mod's source code could not be found for QUAKED).
 2010-12-26 19:06:39 +09:00

8653f9d9a7 Add a man page for zpak 
It's lame, but so is zpak :)

1a767849ab Sort the options in the switch. 
Should make finding them a little easier.
 2010-12-24 17:35:33 +09:00
Bill Currie
d6b3d4891a Finally, help output for qfprogs. 
Nothing great, but better than nothing.

Bill Currie
2229c7557d Update cross-build scripts. 
They're hard-coded for my current setup, but easy to fix.
 2010-12-23 11:45:08 +09:00
Bill Currie
de04e1b602 Lots of win32 (mingw cross) build fixes. 
HTTP (curl) support is missing, but everything else builds.
 2010-12-23 11:40:16 +09:00
Bill Currie
6c631c6d5d Start documenting qfcc. 2010-12-19 11:35:18 +09:00
Bill Currie
52e844ee48 Produce slightly better v6 modulo code for complex inputs. 
I'm having problems with temp defs, but I imagine this code is rarely used
so I won't worry about it for now. It will, however, make a good test case
for when I rework emit.c after I do some reading.
 2010-12-19 11:23:33 +09:00

d981968208 v6 modulo implementation now produces good code. 
At least for simple inputs, anyway. That needs to be tested next.

00e50c0ad3 Rewrite the v6 modulo implementation. 
While trying to understand bind expressions, I discovered that the v6
modulo code was incorrect. This version is correct but uses one too many
temps. That's next.

699799bfc8 Don't warn when adding a new method to an implementation. 
Methods defined in the implementation but not declared in the interface are
just fine.

4481ba9b0d Allow explicit references to classes and categories. 
Use "@reference ClassName;" or "@reference ClassName(CategoryName);" to
create a refence to the class or category, forcing the defining object file
to be linked into the program when the object file is part of a library.

2c84ae4898 Don't let casting in constfold increment users. 
This fixes Deek's temp notice. No new notices have shown up, so this should
be the correct fix. The constant folding code no longer calls cast_expr
directly, but rather uses an internal wrapper that decrements users after
cast_expr increments it, resulting in a no-op.

74d959ec64 Cope gracefully with wadfiles we can't handle 
This is a weird little diff. We're doing a lot of gymnastics here so that
we don't have to crash (killing any loaded unsaved work!) when we find a
wadfile we don't know how to deal with.

Make sure we don't add a new key-pair when the key already exists, and if
the existing value has the same pointer as the "new" value, do nothing.
