* mesa: Add decoding functions for GL_COMPRESSED_SIGNED_R11_EACAnuj Phogat2012-12-075-3/+126
| | | | | | | | | | | | | | | | | | | | | | | | | Data in GL_COMPRESSED_SIGNED_R11_EAC format is decoded and stored in MESA_FORMAT_SIGNED_R16. v2: 16 bit signed data is converted to 16 bit unsigned data by adding 2 ^ 15 and stored in an unsigned texture format. v3: 1. Handle a corner case when base code word value is -128. As per OpenGL ES 3.0 specification -128 is not an allowed value and should be truncated to -127. 2. Converting a decoded 16 bit signed data to 16 bit unsigned data by adding 2 ^ 15 gives us an output which matches the decompressed image (.ppm) generated by ericsson's etcpack tool. ericsson is also doing this conversion in their tool because .ppm image files don't support signed data. But gles 3.0 specification doesn't suggest this conversion. We need to keep the decoded data in signed format. Both signed format tests in gles3 conformance pass with these changes.

| | | | | | | | | | | | | | | | | | | | | | | This patch implements all of the built-in types for GLSL 3.00 ES. This is almost exactly the same as the set of built-in types for GLSL 1.30, except ate 1D samplers are skipped, and samplerCubeShadow is added. This patch also addes an assertion so that when we add new GLSL versions, we'll notice that we need to update the types. In review, Eric noted: "This change looks correct. The overall interaction of profiles is getting ugly, though. I'm imagining a restructure of the symbol table population so that there's a big list of types, and each #version has a nice list of strings of type names copy and pasted out of its spec."

* glsl: Clean up shading language mixing check for GLSL 3.00 ES.Paul Berry2012-12-061-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we prohibited mixing of shading language versions if min_version == 100 or max_version >= 130. This was technically correct (since desktop GLSL 1.30 and beyond prohibit mixing of shading language versions, as does GLSL 1.00 ES), but it was confusing. Also, we asserted that all shading language versions were between 1.00 and 1.40, which was unnecessary (since the parser already checks shading language versions) and doesn't work for GLSL 3.00 ES. This patch changes the code to explicitly check that (a) ES shaders aren't mixed with desktop shaders, (b) shaders aren't mixed between ES versions, and (c) shaders aren't mixed between desktop GLSL versions when at least one shader is GLSL 1.30 or greater. Also, it removes the unnecessary assertion. [v2, idr]: Slightly tweak the is_es_prog detection to occur outside the loop instead of doing something special on the first loop iteration.
