Only a little.  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).
