You use -O3 that bloats the code by inlining functions.  The bloat might 
be such that it overshadows any gains from the extra register that 
-fomit-fram-pointer gets.

But that's speculation.  You need to look at the code produced by GCC to 
understand the reason.  In general, I find -O3 a bad idea.
