Bruce Evans	0f79d73473	Support printf format checking of FreeBSD kernel formats %[Dbrz]. ... This is enabled by the undocumented option -fformat-extensions. This option should be named better and/or give more control over the extensions. Fixed a message - don't warn about the field width when it's the precision that has the wrong type. Didn't fix excessive checking for the precision relative to the type - ANSI requires both to be ints, but gcc permits the field width to be either int or unsigned int.	1998-08-24 06:33:52 +00:00
John Polstra	3bc25faee6	Add support for a new archetype "printf0" for the "format" function ... attribute. It is like the existing "printf" archetype, except that it doesn't complain if the format string is a null pointer. See the node "Function Attributes" in the GCC info pages if you don't know what this is all about. This change will allow us to add format string checking for the err(3) family of functions.	1998-07-15 04:22:45 +00:00
Peter Wemm	a4cd5630b0	Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the ... non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.	1996-09-18 05:35:50 +00:00
