* glsl: Expose gl_MaxTess{Control,Evaluation}AtomicCounters.Matt Turner2015-09-281-8/+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").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we had an enum called gl_shader_type which represented pipeline stages in the order they occur in the pipeline (i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several inconsistently named functions for converting between it and other representations: - _mesa_shader_type_to_string: gl_shader_type -> string - _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type - _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type - _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string This patch tries to clean things up so that we use more consistent terminology: the enum is now called gl_shader_stage (to emphasize that it is in the order of pipeline stages), and the conversion functions are: - _mesa_shader_stage_to_string: gl_shader_stage -> string - _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage - _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage - _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES, for consistency with the new name for the enum.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ever since the addition of interface blocks with instance names, we have had an implicit invariant: var->type->is_interface() == (var->type == var->interface_type) The odd use of == here is intentional because !var->type->is_interface() implies var->type != var->interface_type. Further, if var->type->is_array() is true, we have a related implicit invariant: var->type->fields.array->is_interface() == (var->type->fields.array == var->interface_type) However, the ir_variable constructor doesn't maintain either invariant. That seems kind of silly... and I tripped over it while writing some other code. This patch makes the constructor do the right thing, and it introduces some tests to verify that behavior. v2: Add general-ir-test to .gitignore.
