What I mean is that it seems from experimental results that :
for(int i=0;i<16;++i) // code is more often unrolled than for(int i =
foo();i<bar();++i) // code
Concerning your remark :
"While access by index is theoretically slower than pointer increments,
I'm pretty sure any compiler optimizes the former to the latter. "
you're perfectly right.
