--- Comment #37 from Thomas Henlich <thenlich at gcc dot gnu.org> --- It would make sense to keep optimization in mind: Several calls to conversions of the same value should be performed only once. As a special case: Calls to compute sind(x) and cosd(x) should be optimized to a conversion, followed by a call to sincos. The conversion could also be provided as a user function, for example in code like y=tand(x)-deg2rad(x) the conversion would need to be performed only once.
