The analyzer has found some code that can be optimized. The code contains a call of a function which accepts as its arguments several calls of one and the same function with identical arguments.
Consider the following sample:
....
init(cos(-roty), sin(-roty),
-sin(-roty), cos(-roty));
....The call of such a function works slowly, while this effect will be intensified if this code fragment is placed inside a loop. You'd better rewrite this code. For instance, you may create a temporary variable:
....
double cos_r = cos(-roty);
double sin_r = sin(-roty);
init(cos_r, sin_r, -sin_r, cos_r);
....You cannot always change the code that way, of course. Moreover, this refactoring doesn't always guarantee that you get a performance gain. But such optimizations may be very helpful sometimes.
