Right. Do we need to document this better? There are more builtins that can generate code for older archs than you might expect (like, set_fpscr_rn). Hrm, it *is* documented, but in a big wall of text. Not sure we can do much better though, there simply are this many builtins, but maybe you have an idea how to arrange things better? Anyway: okay for trunk. Thanks! Segher
