* Sync with bgfx upstream revision b91d0b6
* Sync with bx upstream revision d60912b
* Sync with bimg upstream revision bd81f60
* Add astc-codec decoder
* Rename VertexDecl to VertexLayout
* Rename UniformType enum Int1 to Sampler.
* Add NVN stub
* Fix unused-const-variable error on macOS
* Drop redundant explicit language parameters
buildoptions_cpp are only applied to c++ files and buildoptions_objcpp are only
applied to objective c++ files. As such, hardcoding -x offers no benefit while
preventing overrides (such as one needed by 3rdparty/bgfx/src/renderer_vk.cpp on
macOS) from working.
* Re-introduce -x c++ in places where C code is compiled as C++ to prevent clang from throwing a warning
* Build bgfx as Objective-C++ on macOS
It is needed due to included headers
* Enable Direct3D12 and Vulkan bgfx rendering backends
* Enable building of spirv shaders
* Properly escape /c in cmd call
* Comment out dx12 bgfx renderer
* Honor VERBOSE setting during shaders build
* Only invert hlsl shader XYZ_TO_sRGB matrix for opengl
* Add spirv shaders
* OpenGL ES needs transposed matrix too
* Metal needs transposed matrix as well
Trying to evaluate __GLIBC__ will result in an error if is not defined,
if the preprocessor does not short-cut the evaluation.
Split the macros onto separate lines and define the result in a new
BX_USE_GLIBC_PTHREAD_SETNAME_NP macro to avoid duplication.
Fix potential compilation error by ensuring __GLIBC__ is only evaluated
when actually defined.
When __GLIBC__ is defined, we do not need any additional headers on BSD
platforms (hence why using #elif).
I've filed a more complete patch for this upstream:
https://github.com/bkaradzic/bx/pull/61
but this has been ignored since June. This patch is the minimal
set to fix the build on NetBSD.
