Hi, Mesa fails the following dEQP tests:
dEQP-GLES3.functional.shaders.linkage.varying.rules.invalid_type_struct_array dEQP-GLES3.functional.shaders.linkage.varying.rules.invalid_type_struct_struct dEQP-GLES3.functional.shaders.linkage.varying.rules.invalid_type_array_struct they are about defining a struct with an array field, a struct inside a struct and an array of structs respectively. dEQP considers these types invalid but Mesa allows them. I thought this was a bit odd but then I read this in the GLSL ES spec, chapter 4.3.4. Input variables (and similar text exists for the desktop version): "Fragment inputs can only be signed and unsigned integers and integer vectors, float, floating-point vectors, matrices, or arrays or structures of these." That text suggests that the tests are correct and these types are invalid (at least as inputs of a fragment shader). I think that is an odd restriction, and then is the fact that not only Mesa, but also nVidia and AMD proprietary drivers support this. I also tested these types using Khronos' glslangvalidator tool and it does not complain, so it looks a lot like a spec bug to me... Should we file a bug report against the spec? Ian, what do you think? Iago _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
