Richard Smith	1b98ccc4e9	PR20356: Fix all Sema warnings with mismatched ext_/warn_ versus ... ExtWarn/Warnings. Mostly the name of the warning was changed to match the semantics, but in the PR20356 cases, the warning was about valid code, so the diagnostic was changed from ExtWarn to Warning instead. llvm-svn: 213443	2014-07-19 01:39:17 +00:00
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
