Add amdgpu.expected.active.lane metadata which can be applied to operations by a compiler front-end. Do not apply the DPP atomic optimizer to LDS atomics where less than five active lanes are expected. This is an empirically derived threshold based on GFX11 and GFX12 testing. --------- Co-authored-by: YaFan <YaFan.Tao@amd.com>
This directory contains testcases that the verifier is supposed to detect as malformed LLVM code. Testcases for situations that the verifier incorrectly identifies as malformed should go in the test/Assembler directory.
