Done, ta. Next thing I plan on doing is to add fenv.h and the related
functions in newlib, starting with rounding modes and precision control.
[ I'm not working to any strict plan here, but the mplayer-vs-llrintf thing
made me look at the math library code closely, and I think we can replace the
slow soft float stuff from newlib with x87 fpu insns, which would be nice, and
user control over the fpu precision is required for one of the mitigating
workarounds for GCC PR323, which might be helpful as we have a number of
people who like using cygwin + g77 to do heavy-duty academic number crunching,
so I'm going to try and tidy up a few of these bits and pieces and hopefully
we'll get some modest performance improvements in application performance as
well as adding missing functionality. ]
Can't think of a witty .sigline today....
