* glsl: tidy up struct with a single memberTimothy Arceri2015-12-301-1/+1
| | | | | | | | | | | There used to be more members but they now share other fields in order to keep memory use low. Also making the naming more generic will allow us to reuse the field for explicit byte offsets within blocks for ARB_enhanced_layouts. Reviewed-by: Edward O'Callaghan <[email protected]>

* glsl: add subroutine index qualifier supportTimothy Arceri2015-11-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | ARB_explicit_uniform_location allows the index for subroutine functions to be explicitly set in the shader. This patch reduces the restriction on the index qualifier in validate_layout_qualifiers() to allow it to be applied to subroutines and adds the new subroutine qualifier validation to ast_function::hir(). ast_fully_specified_type::has_qualifiers() is updated to allow the index qualifier on subroutine functions when explicit uniform locations is available. A new check is added to ast_type_qualifier::merge_qualifier() to stop multiple function qualifiers from being defied, before this patch this would cause a segfault. Finally a new variable is added to ir_function_signature to store the index. This value is validated and the non explicit values assigned in link_assign_subroutine_types().

* glsl: Fix variable_referenced() for vector_{extract,insert} expressionsIago Toral Quiroga2015-10-141-0/+16
| | | | | | | | | | | | | | We get these when we operate on vector variables with array accessors (i.e. things like a[0] where 'a' is a vec4). When we call variable_referenced() on these expressions we want to return a reference to 'a' instead of NULL. This fixes a problem where we pass a[0] as the first argument to an atomic SSBO function that expects a buffer variable. In order to check this, we use variable_referenced(), but that is currently returning NULL in this case, since the underlying rvalue is a vector_extract expression.

* glsl: Add parser/compiler support for unsized array's length()Samuel Iglesias Gonsalvez2015-09-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unsized array length is computed with the following formula: array.length() = max((buffer_object_size - offset_of_array) / stride_of_array, 0) Of these, only the buffer size needs to be provided by the backends, the frontend already knows the values of the two other variables. This patch identifies the cases where we need to get the length of an unsized array, injecting ir_unop_ssbo_unsized_array_length expressions that will be lowered (in a later patch) to inject the formula mentioned above. It also adds the ir_unop_get_buffer_size expression that drivers will implement to provide the buffer length. v2: - Do not define a triop that will force backends to implement the entire formula, they should only need to provide the buffer size since the other values are known by the frontend (Curro). v3: - Call state->has_shader_storage_buffer_objects() in ast_function.cpp instead of using state->ARB_shader_storage_buffer_object_enable (Tapani).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A simple shader such as vec4 color; color.xy.x = 1.0; would cause ir_assignment::set_lhs() to generate bogus IR: (swiz xy (swiz x (constant float (1.0)))) We were setting the number of components of each new RHS swizzle based on the highest channel used in the LHS swizzle. So, .xy.y would generate (swiz xy (swiz xx ...)), while .xy.x would break. Our existing Piglit test happened to use .xzy.z, which worked, since 'z' is the third component, resulting in an xxx swizzle. This patch sets the number of swizzle components based on the size of the LHS swizzle's inner value, so we always have the correct number at each step. Fixes new Piglit tests glsl-vs-swizzle-swizzle-lhs-[23]. Fixes ir_validate assertions in in Metro 2033 Redux. v2: Move num_components updating completely out of update_rhs_swizzle (suggested by Timothy Arceri). Simplify.
