* i965: Perform basic optimizations on the BROADCAST opcode.Francisco Jerez2015-05-048-0/+44

* i965: Introduce the BROADCAST pseudo-opcode.Francisco Jerez2015-05-046-0/+98
| | | | | | | | | | | | | | | | | | | The BROADCAST instruction picks the channel from its first source given by an index passed in as second source. This will be used in situations where all channels from the same SIMD thread have to agree on the value of something, e.g. a surface binding table index. This is in particular the case for UBO, sampler and image arrays, which can be indexed dynamically with the restriction that all active SIMD channels access the same index, provided to the shared unit as part of a single scalar field of the message descriptor. Simply taking the index value from the first channel as we were doing until now is incorrect, because it might contain an uninitialized value if the channel had previously been disabled by non-uniform control flow. v2: Minor style fixes. Improve commit message. Reviewed-by: Matt Turner <[email protected]>

* mesa: Update image unit state when glBindImageTexture is called with texture=0.Francisco Jerez2015-05-041-16/+15
| | | | | | | | | | There's no indication in the spec that the image unit state other than the bound texture object shouldn't be updated when glBindImageTexture() is called passing the zero texture as argument. It's very unlikely that any application would ever have relied on this, but it's easy to get right, and it fixes the "state" ARB_shader_image_load_store piglit test.

* mesa: Initialize image units to default state on context creation.Francisco Jerez2015-05-043-0/+21

* mesa: Validate original image internal format rather than derived mesa format.Francisco Jerez2015-05-041-3/+3
| | | | | | | | | | | This matches what _mesa_BindImageTextures() does. The derived image format (gl_texture_image::TexFormat) isn't necessarily equivalent to the internal format of the texture image. If a forbidden internal format has been specified we need to mark the image unit as invalid as required by the spec, regardless of the derived format. Fixes the "invalid" ARB_shader_image_load_store piglit test. Reviewed-by: Matt Turner <[email protected]>

From now on all typed and untyped surface access opcodes will follow the same pattern: src[0] will be the message payload, src[1] will be the surface index and src[2] will be a control immediate (atomic operation for atomic opcodes and number of vector components for surface read and write opcodes).

| | | | | | | | | | | | | | For ES, we set the max counts based on SIMD8, which is currently accurate. For desktop GL, we set the max counts based on SIMD16, which can fail in some cases where a SIMD16 program is not currently supported. Therefore, this value is not currently accurate, but will work fine in many cases, and lets us run more test cases. Eventually we want to always be able to generate a SIMD16 program.
