RE: Kernel IEEE Math Completion (everything is zeroed!?!)
Same here on EV56 (Alphastation 500/500) with gcc 4.0.4 20060507
(prerelease) (Debian 4.0.3-3) on Linux 2.6.16-2-alpha-generic:
thetaphi@alpha:~$ ./test
Please enter the num: 0
Please enter the den: 0
0/0 = 0
thetaphi@alpha:~$ ./test
Please enter the num: 1
Please enter the den: 0
1/0 = 0
thetaphi@alpha:~$ ./test
Please enter the num: 1e-320
Please enter the den: 2
9.99989e-321/2 = 0

Fwiw, I get the exact same results as Bob on an EV56 (miata) running a
2.6.15 kernel. Gcc version is 3.4.4.

I don't seem to reproduce the problem on 2.6.15.
0/0 = nan
1/0 = inf
9.99989e-321/2 = 4.99994e-321

The gcc I have installed is 4.0.3, but I couldn't guarantee that's what
I used to compile this kernel...
