* glsl: Allow dot() on scalars, and throw out dotlike().Matt Turner2014-03-183-11/+5
| | | | | | | | | | In all uses of dotlike() we're writing generic code that operates on 1-4 component vectors. That our IR requires ir_binop_dot expressions' operands to be 2+ component vectors is an implementation detail that's not important when implementing built-in functions with dot(), which is defined for scalar floats in GLSL.

| | | | | | | | | | | | | | | | | Patch adds a remap table for uniforms that is used to provide a mapping from application specified uniform location to actual location in the UniformStorage. Existing UniformLocationBaseScale usage is removed as table can be used to set sequential values for array uniform elements.

* glsl: Fix broken LRP algebraic optimization.Kenneth Graunke2014-03-021-1/+3
| | | | | | | | | | | | | | | | | | | | | opt_algebraic was translating lrp(x, 0, a) into add(x, -mul(x, a)). Unfortunately, this references "x" twice, which is invalid in the IR, leading to assertion failures in the validator. Normally, cloning IR solves this. However, "x" could actually be an arbitrary expression tree, so copying it could result in huge piles of wasted computation. This is why we avoid reusing subexpressions. Instead, transform it into mul(x, add(1.0, -a)), which is equivalent but doesn't need two references to "x". Fixes a regression since d5fa8a95621169, which isn't in any stable branches.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | From page 14 (page 20 of the PDF) of the GLSL 1.10 spec: "In addition, all identifiers containing two consecutive underscores (__) are reserved as possible future keywords." The intention is that names containing __ are reserved for internal use by the implementation, and names prefixed with GL_ are reserved for use by Khronos. Names simply containing __ are dangerous to use, but should be allowed. Per the Khronos bug mentioned below, a future version of the GLSL specification will clarify this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 3.3 (Preprocessor) of the GLSL 1.30 spec (and later) and the GLSL ES spec (all versions) say: "All macro names containing two consecutive underscores ( __ ) are reserved for future use as predefined macro names. All macro names prefixed with "GL_" ("GL" followed by a single underscore) are also reserved." The intention is that names containing __ are reserved for internal use by the implementation, and names prefixed with GL_ are reserved for use by Khronos. Since every extension adds a name prefixed with GL_ (i.e., the name of the extension), that should be an error. Names simply containing __ are dangerous to use, but should be allowed. In similar cases, the C++ preprocessor specification says, "no diagnostic is required." Per the Khronos bug mentioned below, a future version of the GLSL specification will clarify this.

In the resolution of Khronos bug #10903 the same wording applied to atomic counters was decided to mean that they're not allowed inside structures -- Rejecting image member declarations within structures seems the most reasonable option for now.
