URL: https://github.com/llvm/llvm-project/commit/35cf2f42dda4d708741e06570b2dbe91cec4dc41 DIFF: https://github.com/llvm/llvm-project/commit/35cf2f42dda4d708741e06570b2dbe91cec4dc41.diff LOG: [Driver][docs] Document option -mtune as a no-op. This documents that option -mtune is accepted for compatibility with GCC, currently it has no effect, and thus does not currently perform any CPU type specific tuning.
