Ian Ewell bda75597 2016-04-18T17:25:54 Finish NV12 support via streams. The main functionality for NV12 texture support through EGL streams has been added. Updates to the compiler, texture code, and stream code were added to support binding to external D3D11 NV12 textures. An end2end test was also added to test sampling of YUV textures and converting to RGB. There is also a new script to convert BMP files to an NV12 texture ready to load into D3D11 for testing purposes.

Olli Etuaho 5858f7e3 2016-04-08T13:08:46 Re-land "Refactor texture function handling in OutputHLSL" This change is pure refactoring, it does not introduce any functional changes. Separate texture function output into a helper class and further into different helper functions to make the code more maintainable. Some of the logic is simplified slightly by eliminating duplicate cases and limiting the scope of variables where possible, but care has been taken to preserve the exact same functionality as before. Re-land with a fix to typo in include guard.

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.

Olli Etuaho 9b4e8626 2015-12-22T15:53:22 Redesign samplers in shaders on D3D11 Translation of samplers to HLSL on D3D11 is changed as follows: Instead of passing around HLSL sampler and HLSL texture references in shaders, all references to ESSL samplers are converted to constant indices within the shader body. Each ESSL sampler is identified by an unique index. In the code generated to implement ESSL texture functions, these indices are used to index arrays of HLSL samplers and HLSL textures to get the sampler and texture to use. HLSL textures and samplers are grouped into arrays by their types. Each unique combination of a HLSL texture type + HLSL sampler type gets its own array. To convert a unique sampler index to an index to one of these arrays, a constant offset is applied. In the most common case of a 2D texture and a regular (non-comparison) sampler, the index offset is always zero and is omitted. The end goal of this refactoring is to make adding extra metadata for samplers easier. The unique sampler index can be used in follow-up changes to index an array of metadata passed in uniforms, which can contain such things as the base level of the texture. This does not solve the issues with samplers in structs. The interface from the point of view of libANGLE is still exactly the same, the only thing that changes is how samplers are handled inside the shader. On feature level 9_3, the D3D compiler has a bug where it can report that the maximum sampler index is exceeded when in fact it is not. This can happen when an array of samplers is declared in the shader. Because of this the new approach can't be used on D3D11 feature level 9_3, but it will continue using the old approach instead.

Olli Etuaho f5cfc8df 2015-08-06T16:36:39 Track whether a name is internal to ANGLE in a separate class The AST contains identifiers in a few different places: besides symbols, there are also function names, which show up in function signatures and function calls. Any of these can be coming either from the original shader or from inside ANGLE. A class that encapsulates a string and its internalness will be useful for implementing a unified way of handling all names in shader translation. Start implementing this by splitting the functionality out of TSymbol.

This workaround fixed scoped structs with the same name. It would also block any possiblity of linking the structs successfully.
