* | [AMDGPU] Eliminate barrier if workgroup size is not greater than wavefront size | Stanislav Mekhanoshin | 2017-04-06 | 1 | -0/+30 |
If a workgroup size is known to be not greater than wavefront size the s_barrier instruction is not needed since all threads are guarantied to come to the same point at the same time. Differential Revision: https://reviews.llvm.org/D31731 llvm-svn: 299659 |
