Hans Wennborg	aa8c61cf94	-Wformat-non-iso: warn about positional arguments (pr12017) ... This renames the -Wformat-non-standard flag to -Wformat-non-iso, rewords the current warnings a bit (pointing out that a format string is not supported by ISO C rather than being "non standard"), and adds a warning about positional arguments. llvm-svn: 152403	2012-03-09 10:10:54 +00:00
Hans Wennborg	c9dd946852	Warn about non-standard format strings (pr12017) ... This adds the -Wformat-non-standard flag (off by default, enabled by -pedantic), which warns about non-standard things in format strings (such as the 'q' length modifier, the 'S' conversion specifier, etc.) llvm-svn: 151154	2012-02-22 10:17:01 +00:00
Ted Kremenek	e7b9d4342b	Tighten format string diagnostic and make it a bit clearer (and a bit closer to GCC's). ... llvm-svn: 148579	2012-01-20 21:52:58 +00:00
Hans Wennborg	6073e31baa	scanf: parse the 'm' length modifier, and check that the right arguments ... are used with that and the 'a' length modifier. llvm-svn: 148029	2012-01-12 17:11:12 +00:00
Hans Wennborg	fd950878fa	scanf analysis: the 'a' length modifier is valid with a scanlist ... Before r148025 we (accidentally) didn't check whether a length modifier is appropriate for a scanlist, but now we do. llvm-svn: 148026	2012-01-12 15:07:16 +00:00
Hans Wennborg	23926bd2d7	Support the 'a' length modifier in scanf format strings as a C90 ... extension. This fixes gcc.dg/format/c90-scanf-3.c and ext-4.c (test for excess errors). llvm-svn: 146649	2011-12-15 10:25:47 +00:00
