c-common.c (format_wanted_type): Add reading_from_flag.
* c-common.c (format_wanted_type): Add reading_from_flag.
(print_char_table): Mark %s and %S formats with flag "R".
(check_format_info_main): Set up reading_from_flag appropriately.
If aflag, always set writing_in_flag rather than relying on the
format used being a scanf format and so having it set.
(check_format_types): Check for formats reading through null
pointers.
testsuite:
* gcc.dg/c90-printf-1.c: Add test for printf formats reading
through a null pointer.
