8f71986306 Add symbol expressions (like def expressions).
They will eventually replace def expressions. Currently quite broken.

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.

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.

3c9991364b Add a "void return" instruction.
I got fed up with always having to explicty return something.

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.

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.

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.

c73ac30e3f Turns out decrementing the users was very very bad. 2011-01-11 10:56:36 +09:00

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.

abe471110c Make inc/dec_users return the the expression.

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.

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.

fed82466cc The first stages of Quake-Pascal.

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.

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.

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.

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.

4481ba9b0d Allow explicit references to classes and categories.

create a refence to the class or category, forcing the defining object file

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.

a623fb53a7 Proper support for empty structs and unions.
They now have a single private, void, unnamed member, resulting in a size of

669771681a split up and modernize configure.ac
Most of the guts of configure.ac have been moved to config.d and are then
brought in by m4_include. This will make maintaining configure.ac much easier.

Also drop use of PROGRAM and VERSION, using PACKAGE_NAME, PACKAGE_VERSION, and
on occasion, PACKAGE_STRING instead, and clean out some old files we no longer
need.
