--- Comment #15 from Ian Lance Taylor <ian at airs dot com> ---
I mean simply to build the compiler on a couple of little-endian systems using
fp-bit and make sure that the floating point code works correctly.  I don't
mean test fp-bit separately, though that's not a bad idea.  But if we are going
to change something that has been around for more than ten years, we need to
check that the generated code will continue to work.  I have no reason to think
that it won't work, but we must try it.
