+
+ * c-ppoutput.c (scan_translation_unit): Handle CPP_PRAGMA
+ and CPP_PRAGMA_EOL.
+ * c-pragma.c (pragma_ns_name): New typedef.
+ (registered_pp_pragmas): New variable.
+ (c_pp_lookup_pragma): New function.
+ (c_register_pragma_1): If flag_preprocess_only, do nothing
+ for non-expanded pragmas, for expanded ones push pragma's
+ namespace and name into registered_pp_pragmas vector.
+ (c_invoke_pragma_handler): Register OpenMP pragmas even when
+ flag_preprocess_only, don't register GCC pch_preprocess
+ pragma if flag_preprocess_only.
+ * c-opts.c (c_common_init): Call init_pragma even if
+ flag_preprocess_only.
+ * c-pragma.c (c_pp_lookup_pragma): New prototype.
+ * config/darwin.h (DARWIN_REGISTER_TARGET_PRAGMAS): Don't call
+ cpp_register_pragma if flag_preprocess_only.
+
+ * gcc.dg/gomp/preprocess-1.c: New test.
