NetBSD/lib/libc/softfloat/timesoftfloat.c
bjh21 4472dbe5e3 Initial commit of SoftFloat 2a import. This should provide a sensible 
mostly-MI floating-point implementation for use by gcc -msoft-float.
It's currently only used by arm26, but should be usable by other ports
without too much hacking, assuming doubles and u_int64_ts are passed and
returned the same way, and FP formats are IEEEish.
