To avoid confusion, I'd like to note that rgba selector was first introduced in OpenCL C++ kernel language, which is currently in provisional state and will be part of OpenCL version 2.2. https://www.khronos.org/registry/cl/specs/opencl-2.2-cplusplus.pdf (page 18). OpenCL version 2.1 uses OpenCL C 2.0 kernel language, which doesn't support rgba selector. https://www.khronos.org/registry/cl/ - latest versions of OpenCL specs. http://reviews.llvm.org/D20602 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
