Another test case:
extern __inline double atan (double __x)
{
register double __result;
__asm __volatile__ ("fld1; fpatan" : "=t" (__result) : "0" (__x) : "st(1)");
return __result;
}
f(double *p)
{
double theta;
double cos_theta, sin_theta;
theta = atan(*p);
sin_theta = sin(theta);
cos_theta = cos(theta);
*p = atan(sin_theta * cos_theta);
}
