This function is used when dispatching compute shader in order to avoid
mixing compute and 3D registers in the context's dirty list. This
allows the compute code to resuse 3D functions like evergreen_cb, which
return a struct r600_pipe_state and still have control over when and how
the register writes are emitted.
The start_compute_cs atom initializes some config and context registers
to the values needed for running compute shaders. When a compute shader
is dispatched, this atom is emitted after the start_cs_cmd atom, which
initializes registers that are common to both 3D and compute.

Some packets require the shader type bit (bit 1) to be set when
used for compute shaders. The pkt_flag will be initialized to
RADEON_CP_PACKET3_COMPUTE_MODE for any struct r600_command_buffer used
for dispatching compute shaders and it will be or'd against the result of
the PKT3 macro when adding a new packet to a struct r600_command buffer.

For copy propgation, we've dropped the use of a GRF in favor of a
(probably later) use of a different GRF. This definitely requires
invalidating intervals.
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
Since live intervals are based on ip, removing an instruction trashes
the intervals unless we were to go do some surgery. These happen to
usually remove a use of a grf, so it's time to recalculate, anyway.

NOTE: This is a candidate for the 8.0 release branch.
This has less impact than for the FS (4k savings), because it was partially
done already, but makes things more consistent.

We factor out all the EGL book-keeping into dri2_create_image() and
simplify the wayland case by using dupImage.

This reverts commit cbffaf20e9.
Use the PRIx64 macro in the fprintf() call instead, as suggested
by Dylan Noblesmith.

ROUND and TRUNC are implemented with one function to reduce code duplication.
Note: ROUND isn't actually used yet, but probably will be soon.

Converting CMP to SLT+LRP didn't work when src2 or src3 was Inf/NaN.
That's the case for GLSL sqrt(0). sqrt(0) actually happens in many
piglit auto-generated tests that use the distance() function.

Fixes quite a few piglit tests of float->int conversion, integer
division, etc.

If the 'dst' register is the same as the 'pass' register we'll generate
invalid code. Use a temporary register in that case.

Redo this commit, and remove the inclusion of gl2ext.h
from src/mapi/glapi/glapi_priv.h. The include was added in
8f3be33985 to fix a missing prototype for
glDrawBuffersNV and others, but it's not possible to include both
glext.h and gl2ext.h from the same file.
I don't see the missing prototype here (with or without shared glapi)
so I'm just removing the offending #include.
Also, since we're redoing this, update to the most recent gl2ext.2.

That old bug was hidden but the clipper always interpolating in 3d space
no matter what it should have been doing. Now that the interpolation
has been fixed, the bug shows up.
