Optimizing the performance of Gcc compiled programs for BeagleBoard

Researching the various ways to optimize the compilation programs for BeagleBoard, I've come with the following parameters for GCC:

-O3 -fomit-frame-pointer -mfloat-abi=softfp -mfpu=neon -mcpu=cortex-a8 -ftree-vectorize -ffast-math

At the moment they are the best parameters we could get. Maybe you have aditional parameters you use to speed the resulting program's performance?
