2
3 * c-ppoutput.c (scan_translation_unit): Handle CPP_PRAGMA
4 and CPP_PRAGMA_EOL.
5 * c-pragma.c (pragma_ns_name): New typedef.
6 (registered_pp_pragmas): New variable.
7 (c_pp_lookup_pragma): New function.
8 (c_register_pragma_1): If flag_preprocess_only, do nothing
9 for non-expanded pragmas, for expanded ones push pragma's
10 namespace and name into registered_pp_pragmas vector.
11 (c_invoke_pragma_handler): Register OpenMP pragmas even when
12 flag_preprocess_only, don't register GCC pch_preprocess
13 pragma if flag_preprocess_only.
14 * c-opts.c (c_common_init): Call init_pragma even if
15 flag_preprocess_only.
16 * c-pragma.c (c_pp_lookup_pragma): New prototype.
17 * config/darwin.h (DARWIN_REGISTER_TARGET_PRAGMAS): Don't call
18 cpp_register_pragma if flag_preprocess_only.
19
20 * gcc.dg/gomp/preprocess-1.c: New test.
