Using host libm routines is a bad idea, that would make the generated code=
=20
depend on the host libm and processor.  Having a cut-off to avoid constant=
=20
folding these functions for n >=3D 128 might make sense (that cut-off is=20
chosen as the one beyond which the ISO 24747 versions of the functions,=20
and the versions in the standard C++ library, have implementation-defined=20
behavior).=
