Author: dim Date: Fri Dec 23 00:23:37 2011 New Revision: 228822 URL: http://svn.freebsd.org/changeset/base/228822
Log: When building the kernel with clang, it produces several warnings which might be useful in some cases, but which are not severe enough to error out the whole kernel build. Display them anyway, so there is at least some incentive to fix them eventually. Start with -Wtautological-compare warnings. These usually occur when people check if unsigned quantities are negative, or similar cases. To clean these up would be painful, and might give problems if the base type which is compared against changes to signed later on.
