Previously, we were doing it in the midst of the pipeline run, which gave
an opportunity to enable/disable fallbacks, which is certainly the wrong
time to be doing so. This manifested itself in a NULL dereference for PutRow
after transitioning out of a fallback during a run_pipeline in glean glsl1.

This reverts commit e7044d552c6d16389447880b8744a51de1cf0199. It
prevented the driver from ever recovering from a software fallback due
to a program error. The original bug it claimed to fix doesn't appear to
exist post-revert.

Previously, we'd go trashing the heap.

It's misleading to report things like the program having too many native
instructions as a Mesa implementation error, when the program may just be
too big for the hardware.

lim x->0 log(x) = -inf so -FLT_MAX is a better approximation than 0
for LG2(0).

Fixes potential crash on X server shutdown.

I think this should be safe for all of the BSDs.

Since the various BSDs use some different features here,
define PIPE_OS_OPENBSD and PIPE_OS_NETBSD as well

This was redundant as drivers can just keep track of whether they are
inside a begin/end query pair. We want to add more query types later
and also support nested queries, none of which map well onto a flag like
this. No driver appeared to be using the flag.

The renderType parameter to CreateContext() was never used. Also, it
was often passed as zero. Now when it's zero we check if the context
is RGBA or CI mode and set it accordingly.
Fixes bug 24211.

Once we've freed a miptree, we won't see any more state cache requests
that would hit the things that pointed at it until we've let the miptree
get released back into the BO cache to be reused. By leaving those
surface state and binding table pointers that pointed at it around, we
would end up with up to (500 * texture size) in memory uselessly consumed
by the state cache.

This feature corresponds to the Begin/End paradigm. Disabling this
feature also eliminates the use of GLvertexformat completely.

This fixes a NULL-pointer dereference when
eglMakeCurrent(dpy, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT)
is called.

Since sqrt() is basically implemented in terms of RSQ/RCP we'll do a
divide by zero if x=0 and wind up with unpredictable results.
Now use CMP instruction to test for x<=0 and return zero in that case.

These options can be used to force vertex/fragment shaders to be no-op
shaders (actually, simple pass-through shaders). For debug/test purposes.

The combination of fptosi
and sitofp (necessary for trunc/floor/ceil/round implementation)
somehow becomes invalid code.
Skip the instruction combining pass when SSE4.1 is not available.

This silences tons of valgrind warnings in programs that don't call
glClear(), such as progs/demos/gamma.

Nasty bug when the surface is freed and another is allocated right on
top of it. The next time we set the fb state SP thinks it's the same
surface and doesn't flush, and when the flush eventually happens the
surface belongs to a completely different texture.

Call _eglConfigFromContextModesRec to convert __GLcontextModes to
_EGLConfig. Single-buffered configs are no longer skipped.

_eglConfigFromContextModesRec is used to convert a __GLcontextModes to a
_EGLConfig. Note that the config is not validated. An invalid mode
is likely to give an invalid config.

Make it similiar to how contexts and surfaces are looked up. It should
be slightly faster, and work better with multiple displays.
