llvm dev - May 2020 - __syncthreads() inrtinsic seems to be missing from __clang_cuda_device_functions.h

Hi!

I see the `__syncthreads_{and|or|count}()` CUDA intrinsics listed in
https://github.com/llvm/llvm-project/blob/master/clang/lib/Headers/__clang_cuda_device_functions.h
but
the vanilla `__syncthreads()` intrinsic seems to be missing. Is this an
oversight, or is it omitted for a specific reason?

Thank you!

We list it as a builtin and it should be available if the target is nvptx.

Do you have problems due to the missing function?


Cheers,

https://github.com/ycm-core/ycmd seems to require this, as detailed in
https://reviews.llvm.org/D80464. I'll let the issues be sorted out there,
thank you!
