I just tried the same on a ARM Cortex-A9 [1], which VFP is much faster
than A8. But to my astonishment, 5g floating point crunching is 11
times slower than optimized gcc. Something may be related to the long
sys time observation above?
nbody -n 50000000
gcc -O2 -lm nbody.c 71.40u 0.00s 71.41r
gc nbody 862.53u 0.02s 862.78r
gc_B nbody 865.00u 0.05s 865.28r
