Author: dim Date: Mon Apr 14 17:54:01 2014 New Revision: 264464 URL: http://svnweb.freebsd.org/changeset/base/264464 Log: MFC r264345: Amend r263891, by making clang default to DWARF2 debug info format for all FreeBSD versions, not just 10.x and earlier. Apparently too many people seem to have trouble with post-1993 formats. Also remove the related notes about messing with kernel configuration files from UPDATING, which are now superfluous.
