(split_specs_attrs, strip_attrs): Add prototypes. * tree.c (merge_machine_{type,decl}_attributes): New functions. * c-decl.c (duplicate_decls): Call merge_machine_decl_attributes. Update olddecl's attributes too. * c-common.c (strip_attrs): New function. * c-typeck.c (common_type): Call merge_machine_type_attributes. * varasm.c (make_function_rtl): New target macro REDO_SECTION_INFO_P. (make_decl_rtl): Likewise. * c-decl.c (shadow_tag_warned): Call split_specs_attrs. ./cp/ChangeLog: * decl.c (duplicate_decls): Call merge_machine_decl_attributes. Update olddecl's attributes too. (strip_attrs): Remove function. * typeck.c (common_type): Call merge_machine_type_attributes.
