--- Comment #4 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It isn't implemented for any other targets yet. When I use __builtin_hypot
with -ffast-math (I tried on powerpc64-linux) I get a call to __hypot_finite,
instead of just three machine instructions, like e.g.
fmul 2,2,2
fmadd 1,1,1,2
fsqrt 1,1
which is what you get for
double hypot(double x, double y) { return __builtin_sqrt(x*x + y*y); }
Reopened. (Or do you want this PR to be just for x87? If so, why?)
