Author: das Date: Mon Jan 16 04:05:53 2012 New Revision: 230189 URL: http://svn.freebsd.org/changeset/base/230189 Log: Convert softfloat to use the standard exception flag and rounding macros in fenv.h instead of the non-standard and incomplete ones in ieeefp.h. Thanks to Ian Lepore for testing this patch.
