5827 * c-ppoutput.c (pp_dir_change): New function.
5828 * c-common.h (pp_dir_change): New declaration.
5829 * cpplib.h (struct cpp_options): Remove working_directory field.
5830 * cppinit.c (cpp_find_main_file, cpp_push_main_file): Merge back to
5831 (cpp_read_main_file): as before 10-01. Call _cpp_stack_file.
5832 Don't handle -fworking_directory here, but in c_common_post_options.
5833 (read_original_directory): Don't back up when done.
5834 Don't clear no-longer used working_directory flag.
5835 * cpplib.h: Update declarations to match.
5836 * c-lex.c (cb_dir_change): Move to c-opts.c.
5837 (init_c_lex): Don't set dir_change callback here, since we want
5838 to set it even if flag_preprocess_only.
5839 * c-opts.c (cb_dir_change): Function moved from c-lex.c.
5840 (c_common_post_options): Set dir_change callback.
5841 Call pp_dir_change if approporiate.
5842 (finish_options): Don't call cpp_find_main_file here. Hence remove
5843 unneeded parameter and result. Do LC_RENAME for <built-in>.
5844 (c_common_post_options): Call cpp_read_main_file here instead.
5845 (c_common_init): Update accordingly.
5846 (push_command_line_include): Don't cpp_push_main_file.
5847 Do LC_RENAME rather than LC_LEASE to get back to main file.
5848 Compared to pre-10-01 version, inline cpp_rename_to_main_file.
5849 (c_common_parse_file): Call cpp_read_main_file for subsequent main
5850 files, but call finish_options for all files.
5851 * c-opts.c (sanitize_cpp_opts): Don't set cpp_opts->working_directory.
5852 * fix-header.c (read_scan_file): Call cpp_read_main_file instead of
5853 cpp_find_main_file + cpp_push_main_file.
5854 * c-lex.c (fe_file_change): Don't set main_input_filename here.
5855 * opts.c (handle_options): Only set main_input_filename first time.

5873 against FIRST_PSEUDO_REGISTER.
