[PATCH] CPP Macro predicates
https://gcc.gnu.org/ml/gcc-patches/2018-08/msg00897.html
libcpp/
* include/cpplib.h (cpp_user_macro_p, cpp_builtin_macro_p)
(cpp_macro_p): New inlines.
* directives.c (do_pragma_poison): Use cpp_macro_p.
(do_ifdef, do_ifndef): Likewise. Use _cpp_maybe_notify_macro_use.
(cpp_pop_definition): Use cpp_macro_p. Move _cpp_free_definition
earlier. Don't zap node directly.
* expr.c (parse_defined): Use _cpp_maybe_notify_macro_use &
cpp_macro_p.
* files.c (should_stack_file): Use cpp_macro_p.
* identifiers.c (cpp_defined): Likewise.
* internal.h (_cpp_mark_macro): Use cpp_user_macro_p.
(_cpp_notify_macro_use): Declare.
(_cpp_maybe_notify_macro_use): New inline.
* lex.c (is_macro): Use cpp_macro_p.
* macro.c (_cpp_warn_if_unused_macro): Use cpp_user_macro_p.
(enter_macro_context): Likewise.
(_cpp_create_definition): Use cpp_builtin_macro_p,
cpp_user_macro_p. Move _cpp_free_definition earlier.
(_cpp_notify_macro_use): New, broken out of multiple call sites.
* traditional.c (fun_like_macro_p): Use cpp_builtin_macro_p.
(maybe_start_funlike, _cpp_scan_out_logical_line)
(push_replacement_text): Likewise.
gcc/c-family/
* c-ada-spec.c (count_ada_macro): Use cpp_user_macro_p.
(store_ada_macro): Likewise.
* c-ppoutput.c (cb_used_define, dump_macro): Likewise.
* c-spellcheck.cc (should-suggest_as_macro_p): Likewise,
gcc/
* config/rs6000/rs6000-c.c (rs6000_macro_to_expend): Use cpp_macro_p.
* config/powerpcspc/powerpcspe-c.c (rs6000_macro_to_expend): Likewise.
gcc/cp/
* name-lookup.c (lookup_name_fuzzy): Likewise.
gcc/fortran/
* cpp.c (dump_macro): Use cpp_user_macro_p.
