That is just weird. Looking at the cross case, I see tree_function_version= ing being called 5 times, but in all cases DECL_FUNCTION_SPECIFIC_TARGET and DECL_FUNCTION_SPECIFIC_OPTIMIZATION of both old_decl and new_decl are NULL, 4 times from that from cgraph_node::create_version_clone_with_body with NULL target_attributes. So I don't much see how it could make a difference. So, do you really see changes with that commit, if so, are they in the -fno-checking or -fchecking=3D1 case (r13-6738 vs. r13-6739), do any changes appear in -fdump-tree-optimized, or if not, where things differ first with -fdump-noaddr -fdump-rtl-all?=
