e4c76c02f7 llvmpipe: Code generate the texture sampling inside the shader. 
Finally a substantial performance improvement: framerates of apps using
texturing tripled, and furthermore, enabling/disabling texturing only
affects around 15% of the framerate, which means the bottleneck is now
somewhere else.

Generated texture sampling code is not complete though -- we always
sample from the base level -- so final figures will be different.

bf19638a00 prog/glsl: fix Makefile for samplers_array. 
The rule added in 488b3c4d1b does not use the
right INCDIR, breaking the build when GL isn't installed in the default include
paths.

7.5 branch only fix, already fixed in master by rewriting the Makefile

4b01e6f614 r300g: Debug flags infrastructure 
So that debugging is no longer a full-spam-or-nothing approach, you are now
supposed to set the RADEON_DEBUG environment flag just like for classic Mesa.

The available debug flags are different, however. Just running an OpenGL
application with RADEON_DEBUG set to an arbitrary string will print out
helpful information.

Everything must be compiled with -DDEBUG for any of this to work

0612ad4f19 i965: Don't set the complete field when there is more VUE yet to come. 
This should help with things like lightsmark, but I don't have a testcase
for this commit.

a47858e45e i965: Add support for 2 threads in the GS.

verts/sec using GL_QUADs on my GM45.

the fragments.

945d34e88a intel: Align untiled region height to 2 according to 965 docs. 
This may or may not be required pre-965, but it doesn't seem unlikely, and
I'd rather be safe.

94d3b832cc i965: Fix source depth reg setting for FSes reading and writing to depth. 
For some IZ setups, we'd forget to account for the source depth register
being present, so we'd both read the wrong reg, and write output depth to
the wrong reg.

Bug #22603.

63b3fa2bce i965: Assert that the offset in the VBO is below the VBO size. 
This avoids sending a bad buffer address to the GPU due to programmer error,
and is permitted by the ARB_vbo spec.  Note that we still have the opportunity
to dereference past the end of the GPU, because we aren't clipping to a
correct _MaxElement, but that appears to be harder than it should be.  This
gets us the 90% solution.

Bug #19911.

217af32c2d i965: Even if no VS inputs are set, still load some amount of URB as required. 
See comment on Vertex URB Entry Read Length for VS_STATE.

This, combined with the previous three commits, fixes #22945.

This fix is just from code and docs inspection, but it may fix hangs on
some applications.
