if the Ada front-end has an efficient, accurate implementation of x^y, wouldn't it make sense to move it to the back-end (__builtin_pow) so everyone can benefit?
I don't know how efficient or accurate the current implementation is (we are in the process of redoing our math routines from scratch). A fair amount of rewriting would be needed (it's in Ada of course right now, and the rules for raising exceptions are different).
