* glsl: Expose gl_MaxTess{Control,Evaluation}AtomicCounters.Matt Turner2015-09-241-8/+4
| | | | | | | | | | | | | | | | | | | | | ... with only ARB_shader_atomic_counters. I expected to see interactions with ARB_tessellation_shader in the ARB_shader_atomic_counters spec, but they do not exist. It seems that we should unconditionally expose these variables in the presence of ARB_shader_atomic_counters: gl_MaxTessControlAtomicCounters gl_MaxTessEvaluationAtomicCounters This partially reverts commit da7adb99e8. The commit also affected gl_MaxTessControlImageUniforms and gl_MaxTessEvaluationImageUniforms similarly but the ARB_shader_image_load_store spec does list an interaction with ARB_tessellation_shader.

* glsl: Initialize patch member of glsl_struct_fieldMichel Dänzer2015-08-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is apparently a subtle difference in C++ between F f; and F f(); The former will use the default constructor. If there is no default constructor specified, the compiler provides one that simply invokes the default constructor for each field. For built-in basic types, the default constructor does nothing. The later will, according to http://stackoverflow.com/questions/2417065/does-the-default-constructor-initialize-built-in-types) perform value-initialization of the type. For built-in types this means initializing to zero. The per_vertex_accumulator constructor is: per_vertex_accumulator::per_vertex_accumulator() : fields(), num_fields(0) { } This is the second form of constructor, so the glsl_struct_field objects were previously zero initialized. With the addition of an empty default constructor in commit 7ac946e5, per_vertex_accumulator::fields receive no initialization. Fixes a bunch of random (mostly tessellation related) piglit failures since commit 7ac946e5 ("glsl: Add constuctors for the common cases of glsl_struct_field").
