* function.c: Remove all_functions. Make outer_function_chain static. (init_function_start): Don't add new function structure to all_functions. (find_function_data, push_function_context_to, pop_function_context_from, put_var_into_stack, trampoline_address): Update for changed structure element names. (push_function_context_to): Disentangle. (free_after_compilation): Also free F. (expand_dummy_function_end): Don't free cfun here. (put_var_into_stack): Comment why we can't use find_function_data here. (fix_lexical_addr, trampoline_address, ): Use find_function_data. (mark_function_chain): Split into maybe_mark_struct_function and ggc_mark_struct_function. Export the latter. (init_function_once): Mark from cfun and outer_function_chain; not all_functions. * function.h (struct function): Kill next_global. Rename next to outer. All users updated to match. (all_functions, outer_function_chain): Don't declare. * ggc-common.c (ggc_mark_trees): Mark DECL_SAVED_INSNS. * integrate.c (output_inline_function): Clear DECL_SAVED_INSNS, don't touch f->inlinable, after calling rest_of_compilation. * tree.h: Forward-declare struct function. Prototype ggc_mark_struct_function. From-SVN: r45336
