I strongly discourage people from using it.  If you don't care about ABI 
compatibility it might be a few cycles faster.. but it does limit your ability 
to draw from existing EABI software.  (Be it commercial or open source.)

(And yes, I realize this is a minor concern for most embedded systems.. but it 
is an issue.)
