tgsi: add PK2H/UP2H support

The util functions handle the half-float conversion.
Note that piglit won't like it much due to:
a) The util functions use magic float mul conversion but when run inside
softpipe/llvmpipe, denorms are flushed to zero, therefore when the conversion
is from/to f16 denorm the result will be zero. This is a bug which should be
fixed in these functions (should not rely on denorms being available), but
will happen elsewhere just the same (e.g. conversion to f16 render targets).
b) The util functions use trunc round mode rather than round-to-nearest. This
is NOT a bug (as it is a d3d10 requirement). This will result of rounding not
representable finite values to MAX_F16 rather than INFINITY. My belief is the
piglit tests are wrong here but it's difficult to tell (generally glsl
rounding mode is undefined, however I'm not sure if rounding mode might need
to be consistent for different operations). Nevertheless, for gl it would be
better to use round-to-nearest, but using different rounding for GL and d3d10
is an unsolved problem (as it affects things like conversion to f16 render
targets, clear colors, this shader opcode).

Hence for now don't enable the cap bit (so the code is unused).

llvmpipe: drop scissor planes early if the tri is fully inside them

If the tri is fully inside a scissor edge (or rather, we just use the
bounding box of the tri for the comparison), then we can drop these
additional scissor "planes" early. We do not even need to allocate
space for them in the tri.

The math actually appears to be slightly iffy due to bounding boxes
being rounded, but it doesn't matter in the end.

Those scissor rects are costly - the 4 planes from the scissor are
already more expensive to calculate than the 3 planes from the tri itself,
and it also prevents us from using the specialized raster code for small
tris.

This helps openarena performance by about 8% or so. Of course, it helps
there that while openarena often enables scissoring (and even moves the
scissor rect around) I have not seen a single tri actually hit the
scissor rect, ever.

llvmpipe: use vector loads for (optimized) tri raster funcs

When we switched to 64bit rasterization, we could no longer use straight
aligned loads for loading the plane data. However, what the code actually
does for loading 3 planes, is 12 scalar loads + 9 unpacks, and then there's
another 8 unpacks for the transpose we need (!).

It would be possible to do the (scalar) loads of course already transposed
(at least saving the additional unpacks), however instead just use
(un)aligned vector loads, and recalculate the eo values, which is much less
instructions (note in case of the triangle_32_3_4 case, the eo values are
not even used, making the scalar loads + unpacks for them all the more
pointless).

This drops execution time of the triangle_32_3_4 function considerably,
albeit it doesn't really make a measurable difference (for small tris we're
essentially limited by vertex throughput in any case), for triangle_32_3_16
it's essentially noise (the loop is more costly than the initial code there).

(I'm thinking about just ditching storing the eo values in the plane data,
so could switch back to using aligned planes, however right now they are
still used in the other raster functions dealing with planes with scalar
code. Also not touching the ppc code, might not be that bad there in any

8 years agost/mesa: treat a write as a read for range purposes
Ilia Mirkin [Fri, 29 Jan 2016 19:45:38 +0000 (14:45 -0500)]
st/mesa: treat a write as a read for range purposes

We use this logic to detect live ranges and then do plain renaming
across the whole codebase. As such, to prevent WaW hazards, we have to
treat a write as if it were also a read.

For example, the following sequence was observed before this patch:

 13: UIF TEMP[6].xxxx :0
 14:   ADD TEMP[6].x, CONST[6].xxxx, -IN[3].yyyy
 15:   RCP TEMP[7].x, TEMP[3].xxxx
 16:   MUL TEMP[3].x, TEMP[6].xxxx, TEMP[7].xxxx
 17:   ADD TEMP[6].x, CONST[7].xxxx, -IN[3].yyyy
 18:   RCP TEMP[7].x, TEMP[3].xxxx
 19:   MUL TEMP[4].x, TEMP[6].xxxx, TEMP[7].xxxx

While after this patch it becomes:

 13: UIF TEMP[7].xxxx :0
 14:   ADD TEMP[7].x, CONST[6].xxxx, -IN[3].yyyy
 15:   RCP TEMP[8].x, TEMP[3].xxxx
 16:   MUL TEMP[4].x, TEMP[7].xxxx, TEMP[8].xxxx
 17:   ADD TEMP[7].x, CONST[7].xxxx, -IN[3].yyyy
 18:   RCP TEMP[8].x, TEMP[3].xxxx
 19:   MUL TEMP[5].x, TEMP[7].xxxx, TEMP[8].xxxx

Most importantly note that in the first example, the second RCP is done
on the result of the MUL while in the second, the second RCP should have
the same value as the first. Looking at the GLSL source, it is apparent
that both of the RCP's should have had the same source.

Looking at what's going on, the GLSL looks something like

  float tmin_8;
  float tmin_10;
  tmin_10 = tmin_8;
... lots of code ...
  tmin_8 = tmpvar_17;
... more code that never looks at tmin_8 ...

And so we end up with a last_read somewhere at the beginning, and a
first_write somewhere at the bottom. For some reason DCE doesn't remove
it, but even if that were fixed, DCE doesn't handle 100% of cases, esp
including loops.

With the last_read somewhere high up, we overwrite the previously
correct (and large) last_read with a low one, and then proceed to decide
to merge all kinds of junk onto this temp. Even if that weren't the
case, and there were just some writes after the last read, then we might
still overwrite a merged value with one of those.

As a result, we should treat a write as a last_read for the purpose of
determining the live range.

nvc0: avoid crashing when there are holes in vertex array bindings

When using the "shared" vertex array configuration strategy, we bind
each of the buffers as a separate array. However there can be holes in
such vertex buffer lists, so just emit a disable for those.

meta: Use internal functions to set texture parameters

_mesa_texture_parameteriv is used because (the more obvious)
_mesa_texture_parameteri just stuffs the parameter in an array and calls
_mesa_texture_parameteriv.  This just cuts out the middleman.

As a side bonus we no longer need check that ARB_stencil_texturing is
supported.  The test doesn't allow non-supporting implementations to
avoid any work, and it's redundant with the value-changed test.

Fix bug #93717 because the state restore commands at the bottom of
