There were no objections to this so far. I assume it means nobody is opposing this new feature.
Just to give a bit more info and a chance for the last feedback. We don't plan to contribute the whole patch but only around 3K lines + tests. The overall changes will be smaller than OpenCL 2.0. And they will mainly affect C++ code paths in Sema and CodeGen, but some parsing bits too. The time frame to start this work will hopefully be the beginning of April.

The plan would be to take small patches from the github repository and perform any necessary rework and clean up before putting up for review. From the OpenCL side, I don't see any issue with this plan as it doesn't interfere with any current development I am aware of, and also it would be great to progress to the next OpenCL standard. I just want to check if there are any objections from anyone or things we should be aware of before the start. I'm particularly looking for feedback from C++ implementers as there might be some overlap. Additionally, there are two more related threads, which I plan to discuss separately. There is: (i) standard library support libclcxx: https://github.com/KhronosGroup/libclcxx. (ii) and IR generation to SPIRV: http://lists.llvm.org/pipermail/llvm-dev/2018-February/121317.html that we would like to provide as well, in order to allow Clang to produce an end binary targeting a wider range of architectures directly (not just AMD GPU). We expect that the complete open source solution for OpenCL C++ will increase significantly Clang users and unify our development forces i.e. refactoring, bug hunting, etc. The plan would be to do similar for OpenCL C too at a later point of time. Please, contact me if you have any thoughts or comments. Cheers, Anastasia
