…ailabl externally A workaround for https://github.com/llvm/llvm-project/issues/60996 As the title suggested, we can avoid emitting available externally functions which is marked as noinline already. Such functions should contribute nothing for optimizations. The update for docs will be sent seperately if this got approved.
