Possibly we should map the front color to black (zeroes). But not sure
there is a way to do that without generating a shader variant.
Signed-off-by: Rob Clark <robclark@freedesktop.org>
Shaders like:
FRAG
PROPERTY FS_COLOR0_WRITES_ALL_CBUFS 1
DCL IN[0], GENERIC[0], PERSPECTIVE
DCL OUT[0], COLOR
DCL SAMP[0]
DCL TEMP[0], LOCAL
IMM[0] FLT32 { 0.0000, 1.0000, 0.0000, 0.0000}
0: TEX TEMP[0], IN[0].xyyy, SAMP[0], 2D
1: MOV OUT[0], IMM[0].xyxx
2: END
cause unhappyness. They have an IN[], but once this is compiled the
useless TEX instruction goes away. Leaving a varying that is never
fetched, which makes the hw unhappy.
In the process fix a signed vs unsigned compare. If the vertex shader
has max_reg=-1, MAX2() vs an unsigned would not give the desired result.

On Windows, the Piglit primitive-restart test was failing a
glGetError()==0 assertion when it was run w/out any command line
arguments. Piglit's all.py script only runs primitive-restart
with arguments so this case isn't normally hit during a full
piglit run.
The basic problem is Microsoft's opengl32.dll calls glFlush
from wglGetProcAddress() and Piglit uses wglGetProcAddress() to
resolve glPrimitiveRestartNV() which is called inside glBegin/End.
See comments in the code for more info.
Plus, improve the comments for _mesa_alloc_dispatch_table().

This isn't perfect -- the filtering is happening on the srgb values, and
we're decoding afterwards, which is not what you want. I think that's the
cause of some additional texwrap(GL_CLAMP, LINEAR) failures, though many
other texwrap tests on srgb start to pass since unfiltered values come out
correct.
Since the RA has to be done s.t. each one gets its own (adjacent)
register, it would complicate matters if instructions were allowed to be
repeated. This enables copy-propagation use in situations where
previously that might have happened.

While running piglit in virgl, I hit an assert in intel driver.
"qemu-system-x86_64: intel_tex.c:219: intel_map_texture_image: Assertion `tex_image->TexObject->Target != 0x8C18 || h == 1' failed."
Thanks to Eric and Ken for pointing me in the right direction,
Fix the get_tex_depth to do the same fixup as get_tex_rgba does
for 1D array textures.

With current makefiles the build fails because source and build paths
are generated incorrectly. With Android build system the top_srcdir and
top_builddir variables are undefined and all paths are relative to where
Android.mk is located. This ends up with path likes
external/mesa/src/mesa/src/mesa/ for both source and build paths, which
are obviously wrong.
This patch fixes this by overriding resulting SRCDIR and BUILDDIR
variables with empty string, so that paths end up being relative to
Android.mk file again. Appending correct build path to generated files
is already done in Android.gen.mk.

Before, we were hard-coding the base_mrf based on dispatch width not number
of registers spilled at a time. This caused us to emit instructions with a
base_mrf or 14 and a mlen of 3 so we used the magical non-existant m16
register. This fixes the problem.

Previously, we had a MAX_SAMPLER_MESSAGE_SIZE which we used instead.
However, some FB write messages can validly be longer than this so we need
something different. Since MAX_SAMPLER_MESSAGE_SIZE is validly useful on
its own, we leave it alone and add a new MAX_GRF_SIZE that's big enough for
FB writes.
