Runs fine in qemu on my amd64 (Athlon64 3000+) with a 64 bits mode qemu.
5 secondes for bootstrap
1"50 for compling
less than 5 seconds for boot.
test-i386 runs but isn't conform to the reference (seems to be sign
extension related bug => 64 bits ?): see attached screen dump. A test
with qemu-user gives the same result, in fact...
test.sh and linux-test just Oooops...
Nbench results:
(in qemu, native, ratio)
Numeric sort 91.72 | 1432.4 => 15
string sort 4.1145 | 111.68 => 27
bitfield 2.8079e+07 | 2.4296e+08 => 8.7
FP emulation 6.1485 | 105.4 => 17
Fourier 2867.8 | 16789 => 5
Assignment 1.1278 | 25.758 => 22
Idea 286.04 | 1901.3 => 6
Huffman 87.261 | 1155.8 => 13
Neural net 0.97965 | 30.367 => 30
LU dec 34.942 | 921.12 => 26
======================================
Memory index 0.683 | 11.952 => 17.5
Integer index 0.852 | 10.562 => 12.4
FP Index 1.166 | 19.646 => 16.8
Don't know what neural net does, but qemu doesn't like it :-(
There, you may find stuff to optimise ;-)
