* glsl: Relax qualifier ordering restriction in ES 3.1.Matt Turner2015-12-081-10/+10
| | | | | | | | | | | ... and allow the "binding" qualifier in ES 3.1 as well. GLSL ES 3.1 incorporates only a few features from the extension ARB_shading_language_420pack: the relaxed qualifier ordering requirements and the binding qualifier.

* glsl: add support for complie-time constant expressionsTimothy Arceri2015-11-211-60/+27
| | | | | | | | | | | | | | | | | | | 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: move stream layout qualifier validationTimothy Arceri2015-11-211-9/+2
| | | | | | | | | | | | | | | | | We are moving this out of the parser in preparation for compile time constant support. The reason a validation function is used rather than an apply function like what is used with bindings is because glsl allows streams to be defined on members of blocks even though they must match the stream thats associated with the current block, this means we need access to the value after validation to do this comparision.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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]>

There is very little spec guidance on exactly which combinations should be allowed, but with ARB_sso it's useful to allow these qualifiers with rendezvous-by-location. Since it's unclear exactly where the layout qualifier should appear when combined with other qualifiers, we will allow it anywhere before the auxiliary storage qualifier.
