The transformations that the compiler does, especially with -O, are sufficiently complex that trying to second-guess the performance effects of source changes is difficult. You'd get a much better handle on this by reading the post-optimised program, which you can get with -ddump-simpl. Good luck! This is not for the faint of heart.
