I have a couple of largish simulation programs that run on Windows and
Linux (and OS/2 because it has a debugger that I love). I need to be
able to ignore underflow errors, generate zero instead of NaN on an
underflow, and turn off denormalized numbers. I can do that on some
compilers and not others... is there a cross-platform solution to
setting reasonably consistent FP processor behaviour?
Thanks,
Phil Hobbs |

Nobody? I'd settle for a good way to do it in gcc, which seems to be
the toughest case, if there really isn't a cross-platform library for
this...
