This patch introduces a new command-line option for clang, namely, amdgpu-precise-mem-op (or precise-memory in the backend). When this option is specified, a waitcnt instruction is generated after each memory load/store instruction. The counter values are always 0, but which counters are involved depends on the memory instruction. --------- Co-authored-by: Jun Wang <jun.wang7@amd.com>
