re PR c++/22476 (-Wmissing-format-attribute should pick out function pointer candidates also)
PR c/22476
* c-common.c (check_function_arguments): Call
'check_function_format' if either -Wformat or
-Wmissing-format-attribute are specified.
* c-format.c (check_function_format): Check -Wformat before
calling 'check_format_info'.
* c-opts.c (c_common_post_options): Don't warn for
-Wmissing-format-attribute without -Wformat.
* c-typeck.c (convert_for_assignment): Detect additional cases for
-Wmissing-format-attribute.
* doc/invoke.texi (-Wmissing-format-attribute): Document new
behavior.
testsuite:
* gcc.dg/format/miss-1.c, gcc.dg/format/miss-2.c: Don't
specify -Wformat for these tests.
* gcc.dg/format/miss-3.c, gcc.dg/format/miss-4.c,
gcc.dg/format/miss-5.c, gcc.dg/format/miss-6.c: New.
* gcc.dg/format/opt-6.c: Delete.
