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.

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

008f4e1929 Don't return .return in advanced mode. 2011-01-13 14:50:25 +09:00

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.

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.

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.

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.

9ac15436d9 More docs. 
Enhance qfprogs qfo debugging.

Make sure functions marked as extern don't emit anything. Fixes the segfault
when building klik.

f7df6fea17 instead of having cpp args in progs.src, potentially breaking some mods, generate progs.i as a series of #includes and then compile everything in one pass 2006-05-24 14:35:39 +00:00

3fb03fc2be hah, should have been using __attribute__((used)) all that time (rather 
than __attribute__((unused))). fixes the missing console in -x11

762aefc9b1 implement Raven's calling convention (rcall: first 2 params in opb and 
opc). should give a general speedup to most progs.

66cabb587f add the vector-calls "optimisation" from fteqcc. makes it possible to 
compile the version of frogbot with waypoints for almost 300 maps.

c3f41e3e69 new opcode: state.f. same as state, but takes a 3rd float operand to 
specify the step for calculating nextthink. accessed using
[frame, think, step] (state is [frame, think])

945006494f short circuit logic for && and || (as per C). forces standard precedence 
(ie, breaks --traditional) when enabled (no choice at the moment, next fix)

23b525059f cast between integer and unsigned just by changing access method 
effectively deprecating conv.ui and conv.iu (they'll die eventually:)

2f6fc5d80c general revamp so params and the return value use proper defs rather than 
hardcoded locations. this will allow use of quaternions in the future.
