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

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.

ad787ae98a Set the expression type to the correct value for addresses. 2011-01-11 12:06:40 +09:00

21d7c78eb7 Allow deep copying of expression trees. 
Certain expression types (eg labels) are created fresh.

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.

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. 
Just for convenience.

18ae178eaf Make new_vector_expr and new_quaternion_expr const-correct. 2011-01-11 08:43:34 +09:00

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

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.

6ebee4ad0e Get the type of Method right. 
It's a direct structure rather than a pointer.

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.

c69ac1f56f Don't segfault when build_builtin_function detects an error. 2011-01-10 12:25:31 +09:00

It's now time to work on the revamp of the symbols, trees, etc.

edaa6235e7 Get functions/procedures emitted. 
No actual code is emitted, though.

25c36a51a8 -f and -F were reversed in the usage. 2011-01-10 12:25:31 +09:00

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.

5627e43465 Use the method's selector rather than its def name in error messages. 2011-01-03 16:25:29 +09:00

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.

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.

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

530e8fae34 Rework class_type_t to be more useful. 
This allows current_class to refer to procols as well (for error
reporting).

f738ef5dba Remove redundant RETURN statement rule. 
The same effect can be achieved with one rule using opt_expr.

1a767849ab Sort the options in the switch. 
Should make finding them a little easier.

d6b3d4891a Finally, help output for qfprogs. 
Nothing great, but better than nothing.

f4d8b82115 Rearrange the options into alpha order. 2010-12-24 17:08:48 +09:00

28740bb57f Add unsigned integer constant support. 2010-12-23 19:32:28 +09:00

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.

f5706f9c44 Make control of expression dumping less of a hassle. 2010-12-19 11:15:13 +09:00

d981968208 v6 modulo implementation now produces good code. 
At least for simple inputs, anyway. That needs to be tested next.
 2010-12-18 22:21:55 +09:00

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.
