Jamie Madill 3c1da04e 2017-11-27T18:33:40 Isolate GlslangWrapper header from most of ANGLE. Since we might want to use the ANGLE PoolAlloc in the Vulkan back-end, we want to make completely sure that it doesn't show up in any header that might be included with the Glslang headers, since this could cause a conflict. This change moves as much as possible to forward-declaring instead of including headers directly in ProgramLinkedResources.h. This means making several internal Program helper classes external. I.E. instead of Program::Bindings, we have ProgramBindings. It also redeclares a "using" in two places, since it isn't possible to forward declare these, and it seemed overdesigned to put the using in a separate header.

Olli Etuaho 465835d6 2017-09-26T13:34:10 Support arrays of arrays in the API The ShaderVariable class that is used as an interface between the compiler and the rest of the code gets arrays of arrays support. Array of array variables are passed from the compiler just like any other variables. However, when stored in Program state each innermost array constitutes a separate variable. This is done to make the implementation match the GLES specification for program interface query APIs. This will be tested more fully once support for parsing arrays of arrays lands in the compiler.

Jamie Madill acf2f3ad 2017-11-21T19:22:44 Apply Chromium style fixes. This addresses several minor code quality issues that are validated in Chromium, but not yet applied to ANGLE: * constructors and destructors must be defined out-of-line * auto is not allowed for simple pointer types * use override everywhere instead of virtual * virtual functions must also be defined out-of-line Slightly reduces binary size for me (~2k on Win, 150k on Linux).

jchen10 85c93c41 2017-11-12T15:36:47 Refactor VaryingPacking Move all packing related logic from Program to VaryingPacking. Do linkValidateTransformFeedback check first to simplify packing. Make getPackedVaryings collect all required VaryingPackings in one run pass, so that packUserVaryings can focus on packing merely.

Olli Etuaho c853804c 2017-09-27T11:20:15 Add support for arrays of arrays to VariableLocation Array indices are sorted so that the outermost index is in the back. This is because we want to be consistent with future arrays of arrays parsing code. In parsing we'll have a utility function to make a TType object into an array, and there it's most natural to push the new outermost sizes to the back of the vector. Further patches will still be needed to parse arrays of arrays and add support to arrays of arrays into the API.

Jamie Madill 192745a7 2016-12-22T15:58:21 Add varying packing validation for WebGL. This CL moves the varying packing from the D3D layer up to Program. This is necessary for WebGL validation, and gives us consistency for the various back-ends. There may be some additional cleanup work on the VaryingPacking class, because it does some work that is D3D- specific. WebGL requires strict varying packing. Instead of allowing success unconditionally, it's an explicit error to succeed to pack a set of varyings that the sample algorithm would fail to pack. Introduce a new packing mode option to the varying packing class to handle this different packing style, while keeping our old more relaxed packing method for ES code.
