Oh, you can sun scons with arcs=gen or arcs=use, that will turn on 
branch profile generation/usage. When I tried it, it made no difference 
(long time ago), does it mean we need to use additional arguments to gcc 
to make it really work? Thanks for the link, I will read it in train, it 
looks interesting.
