It seemed to do little more than what the blurb says: implement soft-float and test itself. This is not very interesting for us on at least i386's, since we already have hard-float with known properties, and Intel and a few hundred million of Intel's customers tested it. The missing test coverage is mainly of the less commonly used math functions (Gamma, Bessel and lots of new C99 functions). Bruce
