Revert "nir: Turn imov/fmov of undef into undef."

2016-12-16T13:01:00+00:00

This reverts commit 6aa730000fea84a14b49828a4bb30761d43903bf.

This was changing the size of the undef to always be 1 (the number of inputs
to imov and fmov) which is wrong, we could be moving a vec4 for example.

spirv: Use a simpler and more correct implementaiton of tanh()

2016-12-15T16:46:28+00:00

The new implementation is more correct because it clamps the incoming value
to 10 to avoid floating-point overflow.  It also uses a much reduced
version of the formula which only requires 1 exp() rather than 2.  This
fixes all of the dEQP-VK.glsl.builtin.precision.tanh.* tests.

compiler/glsl: fix precision problem of tanh

2016-12-15T16:46:11+00:00

Clamp input scalar value to range [-10, +10] to avoid precision problems
when the absolute value of input is too large.

Fixes dEQP-GLES3.functional.shaders.builtin_functions.precision.tanh.* test
failures.

v2: added more explanation in the comment.

mesa: fix active subroutine uniforms properly

2016-12-14T19:03:10+00:00

07fe2d565b introduced a big hack in order to return
NumSubroutineUniforms when querying ACTIVE_RESOURCES for
_SUBROUTINE_UNIFORM interfaces. However this is the
wrong fix we are meant to be returning the number of active
resources i.e. the count of subroutine uniforms in the
resource list which is what the code was previously doing,
anything else will cause trouble when trying to retrieve
the resource properties based on the ACTIVE_RESOURCES count.

The real problem is that NumSubroutineUniforms was counting
array elements as separate uniforms but the innermost array
is always considered a single uniform so we fix that count
instead which was counted incorrectly in 7fa0250f9.

Idealy we could probably completely remove
NumSubroutineUniforms and just compute its value when needed
from the resource list but this works for now.

glsl/lower_output_reads: fix geometry shader output handling with conditional emit

2016-11-24T16:34:41+00:00

Consider a geometry shader that contains code like this:

   some_out = expr;

   if (cond) {
      ...
      EmitVertex();
   } else {
      ...
      EmitVertex();
   }

Both branches should see the correct value of some_out.

Since this is a rather subtle and rare case, I'm submitting a piglit test
for this as well.

GLSL says that the values of output variables are undefined after
EmitVertex(). With this change, the values will now be defined and
unmodified. This may reduce optimization opportunities in the probably
quite rare case where subsequent compiler passes cannot prove that the
value of the output variable is overwritten.

nir/spirv: Fix handling of gl_PrimitiveId

2016-11-24T16:34:40+00:00

Before, we were always treating it as an output which bogus.  The only
stage in which this it can be an output is the geometry stage.  In all
other stages, it's an input which, in the back-end, we actually want to be
a system value.
