qfcc now does local common subexpression elimination. It seems to work, but
is optional (default off): use -O to enable. Also, uninitialized variable
detection is finally back :)
The progs engine now has very basic valgrind-like functionality for
checking pointer accesses. Enable with pr_boundscheck 2
Getting everything right with an enum proved to be too difficult if not
impossible. Also use better tests for equivalence and intersection.
Many more tests have been added. All pass :)
Also move the ALLOC/FREE macros from qfcc.h to QF/alloc.h (needed to for
set.c).
Both modules are more generally useful than just for qfcc (eg, set
builtins for ruamoko).
Aliasing the jump table to an integer broke statement_get_targetlist with
the new alias def handling, and was really wrong anyway. I probably did
that due to being fed up with things and wanting to get qfcc working again
rather than spending time getting jumpb right.
The depth limits in the gl and glsl renderers and in the trace code really
bothered me, but then the fix hit me: at load-time, recurse the trees
normally and record the depth in the appropriate place. The node stacks can
then be allocated as necessary (I chose to add a paranoia buffer of 2, but
I expect the maximum depth will rarely be used).
While accessing short foo[2][4]; as foo[0][0..7] should work in theory, who
knows what gcc does with it when optimizing. I don't know if this will fix
johnnyonflame's bsp loading problem, but no point in having rhinodemonic
code hanging around.
This necessitated disabling the id2 padding, but it's only commented out
incase there's more growth. Now the (compiler) error in -addObjectNoRetain
is caught ealier.
Using "=" was rather confusing, so changing it to "<CONV>" seems to be a
good idea. As the string is used only for selecting opcodes at compile
time, only qfcc is affected.

Going by "standard" Objective-C, retainCount really doesn't belong in
Object itself. The way GNUStep does it is to stash retainCount in memory
just below the object by allocating extra bytes for the count and returning
a pointer just beyond those extra bytes. Now Ruamoko does the same. This
fixes the inconsistencies in structure layouts for Protocol and class
structs between qfcc generated (internal) structs and user visible structs.
The attached patch (against quakeforge git) changes the [con]width,
[con]height, and most importantly the rowbytes members of viddef_t
from unsigned to signed int, like in q2. This allows for a properly
negative vid.rowbytes which may be needed in, e.g. a DIB sections
windows driver if needed. Along with it, I changed a few places
where unsigned int is used along with comparisons against the relevant
vid.* members.
One thing I am not 100% sure is the signedness requirements of
d_zrowbytes and d_zwidth: q2 has them as unsigned but I am not sure
whether that is because they are needed as unsigned or it was just an
oversight of the id developers. They do look like they should be OK
as signed int to me, though: comments?

Note from Bill Currie: I had to do some extra changes as many
signed/unsigned comparisons were somehow missed.
This fixes the horribly different results between optimized and unoptimized
qfbsp (there is still a difference of 1 brushface). Unfortunately, it also
severely limits the maximum size of a map.
It turns out the expected orientation of the sky cube is exactly that of
Blender's default cube looked at from the front view (num-1) and the front
face being the nearest face. This put's Marcher's sun nicely in the view
when exiting the cave.
Rearrange the sky_suffix and sky_coords arrays and remove the sky_target
array such that the faces can be loaded using
GL_TEXTURE_CUBE_MAP_POSITIVE_X + i (apparently certain drivers break if
the faces aren't loaded in the correct order).
Also, the nomalization of the direction vector in the fragment isn't
necessary.
Need to subtract the size of the bsp_t/bsp29_t struct. Now old and new
qfbsp produce identical bsps (so long as they're both unoptimized, or
(probably) both optimized).
All of the nastiness is hidden in bspfile.c (including the old bsp29
specific data types). However, the conversions between bsp29 and bsp2 are
implemented but not yet hooked up properly. This commit just gets the data
structures in place and the obvious changes necessary to the rest of the
engine to get it to compile, plus a few obvious "make it work" changes.
