2009-12-08gallium: fix more potential strict aliasing issuesRoland Scheidegger
In particular, gcc man page warns that union a_union { int i; double d; }; int f() { double d = 3.0; return ((union a_union *) &d)->i; } "might" not be ok (why not?), even though it doesn't seem to generate any warnings. Hence don't use this and do the extra step to actually use assignment to get the values in/out of the union. This changes parts of 3456f9149b3009fcfce80054759d05883d3c4ee5.
2009-12-07mesa: fix shader prog_execute strict aliasing violationsRoland Scheidegger
use unions instead of pointer casts.
2009-12-07gallium/util: fix util_color_[un]pack[-ub] to be strict aliasing safeRoland Scheidegger
use pointer to union instead of void pointer. gcc complained a lot, depending what the pointer originally actually was. Looks like it's in fact maybe legal to cast for instance uint pointers to union pointers as long as union contains a uint type, hence use this with some callers, other just use union util_color in the first place.

2009-12-03mesa: use _mesa_memcpy for COPY_4FV macroRoland Scheidegger
Gets rid of one of the worst strict-aliasing offenders, and actually produces faster code (at least in some cases, when compiler can use for instance 64bit moves for memcpy). (note _mesa_memcpy should get inlined)
2009-12-03gallium: fix ref counting bug in pb_bufmgrJosé Fonseca
This was discovered by the pipe_reference api change.
2009-12-03gallium: fix reference counting functions to be strict-aliasing compliantRoland Scheidegger
Historically, parts of mesa code are not strict-aliasing safe, hence -fno-strict-aliasing is needed to compile (this got forgotten for scons builds for gallium, which indeed not only caused compiler warnings but also unexplicable crashes in non-debug builds). However, we should try to eliminate code not complying with strict-aliasing code at least for gallium. Hence change pipe_reference functions to make them strict-aliasing compliant. This adds a bit more complexity (especially for derived classes) but is the right thing to do, and it does in fact fix a segfault.

function" This reverts commit 792888121b92913733daec7526c9441f27ce1231. We're instead returning 0 for the PIPE_CAP_MAX_VERTEX_TEXTURE_UNITS query.

The driver (and draw module) don't support vertex shader textures yet.

2009-12-01r300g: simplify allocations of VS output registersMarek Olšák
No need to parse TGSI tokens since it's easier to walk through shader semantics. Also fog coordinates now work reliably.

2009-12-01r300g: clean up derived statesMarek Olšák
The state setups which aren't derived anymore have been moved to the VS and FS objects.
2009-12-01r300g: VS->FS attribute routing reworkMarek Olšák
Now it always correctly pairs up VS and FS even if the semantics and indices of VS outputs and FS inputs don't match.
