I've decided to do reentrant versions of the set allocators and I didn't
particularly like the invasiveness of allocating sets this way.
This bypasses set_new, but completely removes the use of the global lock
from within RecursiveClusterFlow. This seems to give a small speedup: 203
seconds threaded.
I think the reason I didn't think of that when I tried to improve qfvis's
performance many years ago is I just simply did not understand
ClipToSeparators. However, the difference caching the separators makes is
phenomenal. Before the change, single threaded qfvis would get stuck on one
particular portal for at least a day (I gave up waiting), but now even a
debug build will complete gmsp3v2.bsp in less than 12 minutes (4 threads on
my quad-core). And that's at level 2! Getting stuck for a day was at level
0.
While noticeably slower than the previous expanded set manipulation code,
this is much easier to read. I can worry about optimizing the set code when
I get qfvis behaving better.
Unfortunately, just because the header is there doesn't mean anything will
actually work :(. Also, the check is based on the host vendor/os for now.
Yes, it's rather lame but it will do for now.
With this, QF will build on an almost fresh ps3toolchain install. Only two
"fixes" are needed:
o In $PS3DEV/ppu/powerpc64-ps3-elf: ln -s ../include sys-include
o libsamplerate cross-built and installed.
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.
Make the params for FreeWinding and CopyWinding consistent with those in
qfbsp. This fixes some doxygen warnings while I think about how best to
handle the duplicate code.
