i965: Remove bad constant buffer constant-reg-already-loaded optimization.
Thanks to branching, the state of c->current_const[i].index at the point
of emitting constant loads for this instruction may not match the actual
constant currently loaded in the reg at runtime. Fixes a regression in my
GLSL program for idr's class since b58b3a786a.
intel: Unmap buffers if needed at DeleteBuffer time.
This fixes a crash in glean's pbo test, which tripped over the assert when a
context was destroyed while a buffer was still mapped (Mesa doesn't call
UnmapBuffer in that case). Regression in
c6bde8873f
i965: Remove the forced lack of caching for renderbuffer surface state.
This snuck in with the multi-draw-buffers commit, and is a major penalty
to performance. It doesn't appear to be required, as the only dependency
the surface BO has is on the state key (and if there's some other dependency,
it should just be in the key).
This brings openarena performance up to almost 2% faster than Mesa 7.4.
i965: Split WM constant buffer update from other WM surfaces.
This can avoid re-uploading constant data when it isn't necessary, and is
a step towards not updating other surfaces just because constants change.
It also brings the upload of the constant buffer next to the creation.
This brings openarena performance up another 4%, to 91% of the Mesa 7.4 branch.
i965: Don't create constant buffers if they won't be used.
Really, the creation and upload of constants should be in the same place,
since they should only happen together, and a state flag should be
triggered by them so that we don't thrash state around so much for just
updating constants. But this still recovers openarena performance by
another 19%, leaving us 16% behind Mesa 7.4 branch.
mesa: only use fallback texture when using shaders, not fixed-function (take two)
The semantics are a little different for shaders vs. fixed-function when
trying to use an incomplete texture. The fallback texture returning
(0,0,0,1) should only be used with shaders. For fixed function, the texture
unit is truly disabled/ignored.
Fixes glean fbo test regression.

mesa: more complete fix for transform_invarient glitches
Add a new flag mvp_with_dp4 in the context, and use that to switch
both ffvertex.c and programopt.c vertex transformation code to
either DP4 or MUL/MAD implementations.
mesa/main: set PREFER_DP4 to match position_invarient code
This is a quick fix for z fighting in quake4 caused by the mismatch
between vertex transformation here and in the position_invarient code.
Full fix would be to make this driver-tunable and adjust both
position_invarient and ffvertex_prog.c code to respect driver
preferences.
gallium/tgsi: hack around linker/archiver breakage
Add a dummy function which exists only so that tgsi_text_translate()
doesn't get magic-ed out of the libtgsi.a archive by the build system.
Don't remove unless you know this has been fixed - check on
mingw/scons builds as well.
mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXEL
Since GL_READ_BUFFER is historically part of the gl_pixel_attrib group
it made sense to signal changes with _NEW_PIXEL. But now with FBOs it's
also part of the framebuffer state.
Now _NEW_PIXEL strictly indicates pixels transfer state changes.
This change avoids framebuffer state validation when any random bit of
pixel-transfer state is set.
DRI drivers updated too: don't check _NEW_COLOR when updating framebuffer
state. I think that was just copied from the Xlib driver because we care
about dither enable/disable state there.
