Arpith Chacko Jacob 82b0fc2a51 [NVPTX] Add intrinsics to support named barriers. ... Support for barrier synchronization between a subset of threads in a CTA through one of sixteen explicitly specified barriers. These intrinsics are not directly exposed in CUDA but are critical for forthcoming support of OpenMP on NVPTX GPUs. The intrinsics allow the synchronization of an arbitrary (multiple of 32) number of threads in a CTA at one of 16 distinct barriers. The two intrinsics added are as follows: call void @llvm.nvvm.barrier.n(i32 10) waits for all threads in a CTA to arrive at named barrier #10. call void @llvm.nvvm.barrier(i32 15, i32 992) waits for 992 threads in a CTA to arrive at barrier #15. Detailed description of these intrinsics are available in the PTX manual. http://docs.nvidia.com/cuda/parallel-thread-execution/#parallel-synchronization-and-communication-instructions Reviewers: hfinkel, jlebar Differential Revision: https://reviews.llvm.org/D17657 llvm-svn: 293384		2017-01-28 16:38:15 +00:00
