Just to add to this, in C, a for-loop is smaller but less optimized than writing out each statement seperately.

And using cos() or other trig functions might be smaller but a lookup table is much faster.

When you're not specifically dealing with instructions, code size doesn't really have any correlation to speed.

Just to beat a dead horse:

in C, a for-loop is smaller but less optimized than writing out each statement seperately.

...unless the unrolled loop's extra code size causes a cache miss across a slow bus, in which case the for-loop is more optimized (assuming, of course, that the loop fits in a cache line).
