* glsl: add always_active_io attribute to ir_variableGregory Hainaut2015-12-011-0/+7
| | | | | | | | | | | | | | | | | | | | | | The value will be set in separate-shader program when an input/output must remains active. e.g. when deadcode removal isn't allowed because it will create interface location/name-matching mismatch. v3: * Rename the attribute * Use ir_variable directly instead of ir_variable_refcount_visitor * Move the foreach IR code in the linker file v4: * Fix variable name in assert v5 (by Timothy Arceri): * Rename functions and reword comments * Don't set always active on builtins Signed-off-by: Gregory Hainaut <[email protected]> Reviewed-by: Timothy Arceri <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>
* glsl: add subroutine index qualifier supportTimothy Arceri2015-11-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | 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: Add precision information to ir_variableIago Toral Quiroga2015-11-121-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We will need this later on when we implement proper support for precision qualifiers in the drivers and also to do link time checks for uniforms as indicated by the spec. This patch also adds compile-time checks for variables without precision information (currently, Mesa only checks that a default precision is set for floats in fragment shaders). As indicated by Ian, the addition of the precision information to ir_variable has been done using a bitfield and pahole to identify an available hole so that memory requirements for ir_variable stay the same. v2 (Ian): - Avoid if-ladders by defining arrays of supported sampler names and indexing into them with type->sampler_array + 2 * type->sampler_shadow - Make the code that selects the precision qualifier to use an utility function - Fix a typo v3 (Tapani): - rebased - squashed in "Precision qualifiers are not allowed on structs" - fixed select_gles_precision for sampler arrays - fixed precision_qualifier_allowed for arrays of structs v4 (Tapani): - add atomic_uint handling - do not allow precision qualifier on images (issues reported by Marta) v5 (Tapani): - support precision qualifier on image types v6 (Tapani): - set precision qualifier on interface block members Reviewed-by: Samuel Iglesias Gonsálvez <[email protected]>

* glsl: Fix variable_referenced() for vector_{extract,insert} expressionsIago Toral Quiroga2015-10-141-0/+2
| | | | | | | | | | | | | | 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 Gonsalvez2015-09-251-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

Note that it checks the ir_type, then checks that the pointer isn't NULL. There is some disconnect in GCC around the condition in the as_foo functions. return ir_type == ir_type_##TYPE ? (ir_##TYPE *) this : NULL; \ It believes "this" could be NULL, so it emits check outside the function just for fun.

* glsl: Make it possible to ignore built-ins when matching signatures.Kenneth Graunke2014-08-041-1/+3
| | | | | | | | | | | | | | | | | | Historically, we've implemented the rules for overriding built-in functions by creating multiple ir_functions and relying on the symbol table to hide the one containing built-in functions. That works, but has a few drawbacks, so the next patch will change it. Instead, we'll have a single ir_function for a particular name, which will contain both built-in and user-defined signatures. Passing an extra parameter to matching_signature makes it easy to ignore built-ins when they're supposed to be hidden. I didn't add the parameter to exact_matching_signature since it wasn't necessary. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* util: Move ralloc to a new src/util directory.Kenneth Graunke2014-08-041-1/+1
| | | | | | | | | | | | | | | | | | For a long time, we've wanted a place to put utility code which isn't directly tied to Mesa or Gallium internals. This patch creates a new src/util directory for exactly that purpose, and builds the contents as libmesautil.la. ralloc seemed like a good first candidate. These days, it's directly used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl didn't make much sense.
