Here's some more on gcc optimization from 2010, discusses how GCC optimization started eliminating null pointer checks in Linux kernel code necessiting compiling at a lower optimization level (towards the bottom). On the 'good' side, it also mentions tight loops can speed up 30-50% if the compiler can ignore signed integer overflow.
