(_cpp_handle_directive): Reenable macro expander if appropriate. (undefine_macros): Inline body of _cpp_free_definition for speed. Do not call undef callback or _cpp_warn_if_unused_macro. (cpp_get_deps): New interface. * files.c (search_cache): Add pfile argument. Check for file that would be found by "" or <> search here... (_cpp_find_file): ...not here. Correct recorded start_dir of files found by directory-of-current-file search that would be found by "" or <> search. * init.c (cpp_add_dependency_target): Delete. * internal.h (struct lexer_state): Add discarding_output flag. * lex.c (lex_identifier): Compute hash function while scanning. * macro.c (cpp_scan_nooutput): Disable macro expansion outside directives. * makedepend.c: New file. * mkdeps.c (struct deps): Add vpath vector. (apply_vpath, deps_add_vpath): New function. (deps_free): Free vpath vector. (deps_add_dep, deps_add_target): Use apply_vpath. * symtab.c (calc_hash): Use HT_HASHSTEP and HT_FINISH. (ht_lookup_with_hash): New function. * cpplib.h, mkdeps.h: Update prototypes. * symtab.h: Update prototypes. (HT_HASHSTEP, HT_FINISH): New macros. gcc: * Makefile.in (MKDEPS_H): New shorthand. (c-opts.o): Update dependencies. * c-opts.c: Include mkdeps.h. (handle_deferred_opts): Use cpp_get_deps and deps_add_target, not cpp_add_dependency_target. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@82654 138bc75d-0d04-0410-961f-82ee72b054a4 --- libcpp/internal.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'libcpp/internal.h') diff --git a/libcpp/internal.h b/libcpp/internal.h index 9cd9be57cc4..3608201d560 100644 --- a/libcpp/internal.h +++ b/libcpp/internal.h @@ -246,6 +246,10 @@ struct lexer_state /* Nonzero when parsing arguments to a function-like macro. */ unsigned char parsing_args; + /* Nonzero if prevent_expansion is true only because output is + being discarded. */ + unsigned char discarding_output; + /* Nonzero to skip evaluating part of an expression. */ unsigned int skip_eval; }; -- cgit v1.2.3
