Adjustment of sine input values
As we have seen, using SSE instructions is quite convenient and effective; although, as we were mostly loading data from memory to registers and moving it within the registers, we have not been able to see its actual effectiveness yet. There are two procedures called from the calculation loop that perform the actual computations. One of them is the adjust() procedure.
Due to the overall simplicity of the algorithm, and since each of the two procedures is called from exactly one place, we are not following any specific calling convention; instead, we're using the XMM0 register for passing the floating point values and the ECX register for passing integer parameters.
In the case of the adjust() procedure, we ...
