The resolver is only called once per symbol. A few extra cycles to save and restore fp registers will not matter; the savings elsewhere from being able to use vector ops probably more than compensate anyway. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
