Corentin Wallez f0e89be6 2017-11-08T14:00:32 Use packed enums for the texture types and targets, part 1 In OpenGL there are two enum "sets" used by the API that are very similar: texture types (or bind point) and texture targets. They only differ in that texture types have GL_TEXTURE_CUBEMAP and target have GL_TEXTURE_CUBEMAP_[POSITIVE|NEGATIVE]_[X|Y|Z]. This is a problem because in ANGLE we use GLenum to pass around both types of data, making it difficult to know which of type and target a variable is. In addition these enums are placed somewhat randomly in the space of OpenGL enums, making it slow to have a mapping from texture types to some data. Such a mapping is in hot-code with gl::State::mTextures. This commit stack makes the texture types and target enums be translated to internal packed enums right at the OpenGL entry point and used throughout ANGLE to have type safety and performance gains. This is the first of two commit which does the refactor for all of the validation and stops inside gl::Context. This was the best place to split patches without having many conversions from packed enums to GL enums.

Geoff Lang 5d5253a3 2017-11-22T14:51:12 Clean up usage of EXT_debug_marker and KHR_debug in the backends. In RendererGL, the EXT_debug_marker functions were calling the KHR_debug entry points, now they fall back only when EXT_debug_marker is missing. Separated the ContextImpl methods for the two extensions.

Jamie Madill 6d94f064 2017-10-21T22:19:40 Add more complete NULL driver for the GL back-end. This implements a NULL driver in OpenGL by stubbing out most of the GL functions in FunctionsGL except a few static "Gets" that are needed for initialization with Chromium and the tests. It is intended to be used for performance testing ONLY and will not have correct behaviour. It also adds a define to enable conditionally excluding the null entry points for implementations that wish to save on a bit of binary size. Also fixes some of the typedefs in functionsgl_typesdefs.h that were turned up after implementing the direct assignment from NULL stub entry point, generated from gl.xml, to the function pointer with type defined from functionsgl_typedefs.h.
