Fastest sort of fixed length 6 int array

Since these are integers and compares are fast, why not compute the rank order of each directly:
inline void sort6(int *d) {
int e[6];
memcpy(e,d,6*sizeof(int));
int o0 = (d[0]>d[1])+(d[0]>d[2])+(d[0]>d[3])+(d[0]>d[4])+(d[0]>d[5]);
int o1 = (d[1]>=d[0])+(d[1]>d[2])+(d...
