* glcpp: Do not remove spaces to preserve locations.Sir Anthony2014-03-084-5/+5
| | | | | | | | | After preprocessing by glcpp all adjacent spaces were replaced by single one and glsl parser received column-shifted shader source. It negatively affected ast location set up and produced wrong error messages for heavily-spaced shaders. Reviewed-by: Kenneth Graunke <[email protected]>

* 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.

* glsl: convert GS input primitive to use ast_type_qualifierJordan Justen2014-02-206-66/+96
| | | | | | | | | | | | | | | | | | | | | | | | 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. This is important since certain scenerios are not supported until after the primitive type has been specified in the shader code. v4: * Merge with compute shader input layout qualifiers Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>

* glsl: Only warn for macro names containing __Ian Romanick2014-02-191-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glcpp: Only warn for macro names containing __Ian Romanick2014-02-192-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | blocks. Aggregating images inside uniform blocks is explicitly disallowed by the standard, aggregating them inside structures is not (as of GL 4.4), but there is a similar problem as with atomic counters: image uniform declarations require either a "writeonly" memory qualifier or an explicit format qualifier, which are explicitly forbidden in structure member declarations. 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.
