nir: Store some geometry shader data in nir_shader.

This makes it possible for NIR shaders to know the number of output
vertices and the number of invocations.  Drivers could also access
these directly without going through gl_program.

We should probably add InputType and OutputType here too, but currently
those are stored as GL_* enums, and I wanted to avoid using those in
NIR, as I suspect Vulkan/SPIR-V will use different enums.  (We should
probably make our own.)

We could add VerticesIn, but it's easily computable from the input
topology, so I'm not sure whether it's worth it.  It's also currently
not stored in gl_shader (only gl_shader_program), which would require
changes to the glsl_to_nir interface or require us to store it there.

This is a bit of duplication of data...ideally, we would factor these
substructs out of gl_program, gl_shader_program, and nir_shader, creating
a gl_geometry_info class...but it would need to go in a new place (in
src/glsl?) that isn't mtypes.h nor nir.h.

9 years agometa: Use result of texture coordinate clamping operation
Ian Romanick [Wed, 9 Sep 2015 17:27:04 +0000 (10:27 -0700)]
meta: Use result of texture coordinate clamping operation

Previously the result of the complicated clamp() expression just dropped
on the floor: clamp does not modify any of its parameters.  Looking at
the surrounding code, I believe this is supposed to modify the value of
tex_coord.

This change (along with a change to avoid the use of
brw_blorp_framebuffer) does not affect any existing piglit tests.  I'm
not sure what this clamp is trying to accomplish, so I'm not sure how to
write a test to exercise this path.

I also noticed another bug in this code.  There is no way the array
texture case could possibly work.  This will generate code for the
TEXEL_FETCH macro like:

    #define TEXEL_FETCH(coord) texelFetch(texSampler, ivec3(coord), sample_map[int(2 * fract(coord.x))]);

Since the coord parameter of this macro is a vec2 at all invocations, no
expansion of this macro will even compile.

softpipe: Split 3D to 2D coords conversion into separate function

This is to avoid tying the conversion to the sampling -
textureQueryLod will need to do the conversion too, but it does not do
any sampling.

So instead of a "get_samples" vfunc, there is just a bool saying
whether the conversion is needed or not. This solution keeps a nice
property of not adding any overhead for the common case (2D textures).

v2:
  - replaced the "convert_coords" vfunc with a "need_cube_convert"
    boolean to avoid overhead of copying arrays in common case
  - removed an unused typedef
