u_primconvert: Copy min/max_index from the original primitive.
These values are supposed to be the minimum/maximum index values used to
read from the vertex buffers. This code either copies index values out of
the old IB (so, same min/max as the original draw call), or generates a
new IB (using index values between the start and the start + count of the
old array draw info, which just happens to be what min/max_index are set
to by st_draw.c).
We were incorrectly setting the max_index in the
converting-from-glDrawArrays case to the start vertex plus the number of
vertices generated in the new IB, which broke QUADS primitive conversion
on VC4 (where max_index really has to be correct, or the kernel might
reject your draw call due to buffer overflow).

v2: Rebase on helpers change.

vc4: Add support for swizzles of 32 bit float vertex attributes.
Some tests start working (useprogram-flushverts, for example) due to
getitng the right vertices now. Some that used to pass start failing with
memory overflow during binning, which is weird (glsl-fs-texture2drect).
And a couple stop rendering correctly (glsl-fs-bug25902).
v2: Move the attribute format setup in the key from after search time to
before the search.
v3: Fix reading of attributes other than position (I forgot to respect
attr and stored everything in inputs 0-3, i.e. position).

vc4: Crank up the tile allocation BO size
This avoids a simulator assertion failure with glamor. I need to actually
support resize, though.

vc4: Add more useful debug for the undefined-source case
We could get undefined sources in real programs from the wild, so we'll
need to turn off this debug eventually. But for now, using undefined
sources is typically me just mistyping something.

instead of Y. Fixes glean's LIT test.
v3: Rebase on the helpers.

vc4: Refactor uniform handling.
I wanted an easy way to set up new uniforms every time, so I could handle
texture-sampler-related uniforms.
v2: Rebase on helpers change.

Date: Fri Jul 4 10:59:42 2014 -0700
vc4: Add copy propagation between temps.
We put in a bunch of extra MOVs for program outputs, and this can clean
those up. We should do uniforms, too, though.
v2: Fix missing flagging of progress when we actually optimize. Caught by
Aaron Watry.

Date: Fri Jul 4 09:48:23 2014 -0700
vc4: Add dead code elimination.
This cleans up a bunch of noise in the compiled coordinate shaders (since
we don't need the varying outputs), and also from writemasked instructions
with negated src operands.

vc4: Add an initial pass of algebraic optimization.
There was a lot of extra noise in my piglit shader dumps because of silly
CMPs.

vc4: Add support for CMP.
This took a couple of tries, and this is the squash of those attempts.
v2: Fix register file conflicts on the args in the
destination-is-accumulator case.
v3: Rebase on helper change and qir_inst4 change.

vc4: Make scheduling of NOPs a separate step from QIR -> QPU translation.
This should also be used as a way to pair QIR instructions into QPU
instructions later.

vc4: Add WIP support for varyings.
It doesn't do all the interpolation yet, but more tests can run now.
v2: Rebase on helpers.

vc4: Use r3 instead of r5 for temps, since r5 only has 32 bits of storage
Reserving a whole accumulator for temps is awful in the first place, but
I'll fix that later.

vc4: Load the tile buffer before incrementally drawing.
We will want to occasionally disable this again when we do clear support.
v2: Squash with the previous commit (I accidentally committed at two
stages of writing the change)

vc4: Don't reallocate the tile alloc/state bos every frame.
This was a problem for the simulator since we don't free memory back to
it, and it would soon just run out.

vc4: Use the user's actual first vertex attribute.
This is hardcoded to read it as RGBA32F so far, but starts to get more
tests working.

vc4: Fix UBO allocation when no uniforms are used.
We do rely on a real BO getting allocated, so make sure we ask for a non-zero size.

vc4: Switch to actually generating vertex and fragment shader code from TGSI.
This introduces an IR (QIR, for QPU IR) to do optimization on. It's a
scalar, SSA IR in general. It looks like optimization is pretty easy this
way, though I haven't figured out if it's going to be good for our weird
register allocation or not (or if I want to reduce to basically QPU
instructions first), and I've got some problems with it having some
multi-QPU-instruction opcodes (SEQ and CMP, for example) which I probably
want to break down.
Of course, this commit mostly doesn't work, since many other things are
still hardwired, like the VBO data.
v2: Rewrite to use a bunch of helpers (qir_OPCODE) for emitting QIR
instructions into temporary values, and make qir_inst4 take the 4 args
separately instead of an array (all later callers wanted individual
args).

vc4: Start converting the driver to use vertex shaders.
Note: This is the cutoff point where I switched from developing primarily
on the Pi to developing o the simulator. As a result, from this point on
the code is untested on the Pi (the kernel code I have currently wasn't
rendering anything at this commit, though the simulator renders
successfully, suggesting kernel bugs).

vc4: Initial skeleton driver import.
This mostly just takes every draw call and turns it into a sequence of
commands that clear the FBO and draw a single shaded triangle to it,
regardless of the actual input vertices or shaders. I copied the initial
driver skeleton mostly from freedreno, and I've preserved Rob Clark's
copyright for those. I also based my initial hardcoded shaders and
command lists on Scott Mansell (phire)'s "hackdriver" project, though the
bit patterns of the shaders emitted end up being different.
v2: Rebase on gallium megadrivers changes.
v3: Rebase on PIPE_SHADER_CAP_MAX_CONSTS change.
v4: Rely on simpenrose actually being installed when building for
simulation.
v5: Add more header duplicate-include guards.
v6: Apply Emil's review (protection against vc4 sim and ilo at the same
time, and dropping the dricommon drm bits) and fix a copyright header
(thanks, Roland)
