* glsl: allow multiple layout qualifiers for a single declarationTimothy Arceri2016-01-201-1/+2
| | | | | | | | | | | | | | | | | | | | From the ARB_shading_language_420pack spec: "More than one layout qualifier may appear in a single declaration. If the same layout-qualifier-name occurs in multiple layout qualifiers for the same declaration, the last one overrides the former ones." The parser was already failing correctly when the extension is not available but testing for duplicates within a single layout qualifier was still causing this to fail when available as both cases share the same function for merging. Here we add a parameter to differentiate between the two uses and apply it to the duplicate test. Acked-by: Matt Turner <[email protected]> Reviewed-by: Chris Forbes <[email protected]>

* glsl: add subroutine index qualifier supportTimothy Arceri2015-11-211-1/+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: add support for complie-time constant expressionsTimothy Arceri2015-11-211-17/+16
| | | | | | | | | | | | | | | | | | | This patch replaces the old interger constant qualifiers with either the new ast_layout_expression type if the qualifier requires merging or ast_expression if the qualifier can't have mulitple declarations or if all but the newest qualifier is simply ignored. We also update the process_qualifier_constant() helper to be similar to the one in the ast_layout_expression class, but in this case it will be used to process the ast_expression qualifiers. Global shader layout qualifier validation is moved out of the parser in this change as we now need to evaluate any constant expression before doing the validation.

* glsl: add new type for compile time constantsTimothy Arceri2015-11-211-0/+20
| | | | | | | | | | | | | | | | | | | | | | | In this patch we introduce a new ast type for holding the new compile-time constant expressions. The main reason for this is that we can no longer do merging of layout qualifiers before they have been converted into GLSL IR so we need to store them to be proccessed later. The new type has two helper functions: - process_qualifier_constant() Used to merge and then evaluate qualifier expressions - merge_qualifier() Simply appends a qualifier to a list to be merged later by process_qualifier_constant() In order to avoid cascading error messages the process_qualifier_constant() helpers return a bool Reviewed-by: Emil Velikov <[email protected]>

* glsl: add ast/parser support for subroutine parsing storage (v3.2)Dave Airlie2015-07-231-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the guts of the GLSL parser and AST support for shader subroutines. The code creates a subroutine type in the parser, and uses that there to validate the identifiers. The parser also distinguishes between subroutine types/function prototypes /uniforms and subroutine defintions for functions. Then in the AST conversion it recreates the types, and stores the subroutine definition info or subroutine info into the ir_function along with a side lookup table in the parser state. It also converts subroutine calls into the enhanced ir_call. v2: move to handling method calls in function handling not in field selection. v3: merge Chris's previous parser patches in here, to make it clearer what's changed in one place. v3.1: add more documentation, drop unused include v3.2: drop is_subroutine_def Reviewed-by: Chris Forbes <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

The notable ones are where we produce unrolling in cases we didn't before (presumably just because of the lower instruction count). But there are also some cases where pushing things right into the variables prevents copy propagation and tree grafting, since we don't split our variable usage webs apart.

* glsl: convert GS input primitive to use ast_type_qualifierJordan Justen2014-02-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | We introduce a new merge_in_qualifier ast_type_qualifier which allows specialized handling of merging input layout qualifiers. By merging layout qualifiers into state->in_qualifier, we allow multiple input qualifiers. For example, the primitive type can be specified specified separately from the invocations count (ARB_gpu_shader5). state->gs_input_prim_type is moved into state->in_qualifier->prim_type state->gs_input_prim_type_specified is still processed separately so we can determine when the input primitive is specified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the time it is not necessary to perform type inference to compile GLSL; the type of every expression can be inferred from the contents of the expression itself (and previous type declarations). The exception is aggregate initializers: their type is determined by the LHS of the variable being assigned to. For example, in the statement: mat2 foo = { { 1, 2 }, { 3, 4 } }; the type of { 1, 2 } is only known to be vec2 (as opposed to, say, ivec2, uvec2, int[2], or a struct) because of the fact that the result is being assigned to a mat2. Previous to this patch, we handled this situation by doing some type inference during parsing: when parsing a declaration like the one above, we would call _mesa_set_aggregate_type(), which would infer the type of each aggregate initializer and store it in the corresponding ast_aggregate_initializer::constructor_type field. Since this happened at parse time, we couldn't do the type inference using glsl_type objects; we had to use ast_type_specifiers, which are much more awkward to work with. Things are about to get more complicated when we add support for ARB_arrays_of_arrays. This patch simplifies things by postponing the call to _mesa_set_aggregate_type() until ast-to-hir time, when we have access to glsl_type objects. As a side benefit, we only need to have one call to _mesa_set_aggregate_type() now, instead of six. Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | | | | All member variables of ast_node are already being initialized from its constructor, but some of its derived classes were leaving members uninitialized -- Fix them. Using rzalloc makes it more likely that we will start relying on the allocator to zero out all memory if the class is ever extended with new member variables. That's bad because it ties objects to some specific allocation scheme, and gives unpredictable results when an object is created with a different allocator -- Stack allocation, array allocation, or aggregation inside a different object are some of the useful possibilities that come to my mind. v2: Use NULL initialization instead of default construction for pointers.
