Olli Etuaho 1d9dcc24 2017-01-19T11:25:32 Make AST path always include the current node being traversed AST traversers tend to sometimes call traverse() functions manually during PreVisit. Change TIntermTraverser so that even if this happens, all the nodes are automatically added to the traversal path, instead of having to add them manually in each individual AST traverser. This also makes calling getParentNode() return the correct node during InVisit. This does cause the same node being added to the traversal path twice in some cases, where nodes are repeatedly traversed, like in OutputHLSL, but this should not have adverse side effects. The more common case is that the traverse() function is called on the children of the node being currently traversed. This fixes a bug in OVR_multiview validation, which did not previously call incrementDepth and decrementDepth when it should have.

It represents the root node of the tree which is a list of declarations and function definitions, and any code blocks that can be denoted by curly braces. These include function and loop bodies, and if-else branches. This change enables a bunch of more compile-time type checking, and makes the AST code easier to understand and less error-prone. The PostProcess step that used to be done to ensure that the root node is TIntermAggregate is removed in favor of making sure that the root node is a TIntermBlock in the glslang.y parsing code. Intermediate output formatting is improved to print the EOpNull error in a clearer way.

Olli Etuaho 3d932d83 2016-04-12T11:10:30 Defer global initializers when necessary Move global variable initializers that are not constant expressions to a function that gets called at the start of main(). This is done with an AST transformation. This needs to be done because global variable initializers must be constant in native GL, but ANGLE is more lenient with what can be put into ESSL 1.00 global initializers to remain compatible with legacy WebGL content. Non-constant global variable initializers also caused issues in HLSL output, since in HLSL output some types of expressions get unfolded into multiple statements. These include short-circuiting operators and array initialization. To make sure that these cases are covered, any initializers that can't be constant folded are deferred, even if they have the const qualifier. The old deferring mechanism in OutputHLSL is removed in favor of this new AST transformation based approach.

Olli Etuaho 9696316d 2016-03-21T11:54:33 Support ESSL structs containing samplers on D3D Since HLSL can't natively handle samplers in structs, samplers need to be extracted out of structs into separate variables in the translated shader code. In HLSL 4.1, samplers that were in structs go into the normal sampler arrays and are identified by index constants. In other HLSL versions, samplers that were in structs are translated as uniform variables. These transformations are done inside the HLSL output classes, not as tree transformations. This helps to keep the uniform API provided by the shader translator intact. Wherever a struct containing samplers is passed into a user-defined function, the translated HLSL code passes the separate sampler variables alongside a struct where the samplers have been removed. The D3D backend in libANGLE queries the uniform registers of any samplers that were in uniform structs, and adds them to the register maps, so that correct sampler state gets assigned to them. The extracted sampler variables are prefixed with "angle_" instead of the usual "_" to prevent any name conflicts between them and regular variables.

This also improves the maintainability of HLSL output by isolating the unfolding into a separate compilation step. The new version of UnfoldShortCircuit traverser will traverse the tree until an expression that needs to be unfolded is encountered. It then unfolds it and gets reset. The traverser will be run repeatedly until no more operations to unfold are found. This helps with keeping the traverser's design relatively simple.

Olli Etuaho 9638c352 2015-04-01T14:34:52 Support assigning array constructors in HLSL output This adds support to the following type of shader code, where an array constructor is used as a source of assignment: float a[3]; a = float[3](0.0, 1.0, 2.0); The assignment gets replaced in the HLSL code by a function call where the array is an out parameter and the constructor parameters are regular parameters. Constructors cannot yet be used in initializers. With this change in place, some of the relevant dEQP tests start passing.

Nicolas Capens 84cfa124 2014-04-14T13:48:45 Fix Lod0 texture functions that take a bias parameter. Texture functions that are in a divergent path can still take a bias parameter. Treat the bias parameter as an explicit lod. The logic behind this is that the implicit lod is considerd to be 0 like with other Lod0 functions, and then the bias is added to it.

Conservatively assume aggreate and selection operators have side effects for now.
