@cindex sincos math function, implicit usage
@defmac TARGET_HAS_SINCOS
When this macro is nonzero, GCC will implicitly optimize calls to @code{sin}
and @code{cos} with the same argument to a call to @code{sincos}. The
default is zero. The target has to provide the following functions:
@smallexample
void sincos(double x, double *sin, double *cos);
void sincosf(float x, float *sin, float *cos);
void sincosl(long double x, long double *sin, long double *cos);

Define this macro to generate code for Objective-C message sending using
the calling convention of the NeXT system. This calling convention
