Jonathan,
I compiled and built gcc 4.7.0 myself. I am not sure if I build gcc on
my machine, it would be compiled as c++. How would I check that?
Thanks

Consider following loop.
int recal(int *x){int i;
for(i=0;;i+=4){
if(__builtin_expect((x[i]|x[i+1])|(x[i+2]|x[i+3]),0))
break;
}
return (x[i]|x[i+1])*(x[i+2]|x[i+3]);
}
On x64 orl instruction is destructive. Gcc saves intermediate result to
register instead recalculating it at end
