(_cpp_preprocess_dir_only): New function. * directives.c (_cpp_handle_directive): Check directives_only before disabling execution of indented directives. * files.c (_cpp_stack_file): Add directives_only check. * include/cpplib.h (struct cpp_options): Add directives_only. (cpp_init_special_builtins): New function. * init.c (cpp_init_special_builtins): New function. (cpp_init_builtins): Move builtin_array initialization to cpp_init_special_builtins. (post_options): Check directives_only before setting pfile->state.prevent_expansion = 1. * macro.c (_cpp_builtin_macro_text): Print an error if __COUNTER__ is expanded inside a directive while -fdirectives-only is enabled. * Makefile.in (libcpp_a_OBJS): Add directives-only.o. (libcpp_a_SOURCES): Add directives-only.c. gcc/ * c-ppoutput.c (print_lines_directives_only): New function. (scan_translation_unit_directives_only): New function. (preprocess_file): Add call to scan_translation_unit_directives_only. * c-opts.c (c_common_handle_option): Add OPT_fdirectives_only. (sanitize_cpp_opts): Add default flag_dump_macros setting for -fdirectives-only. Add errors for -fdirectives-only conflict with -Wunused-macros and -traditional.
