    I would not recommend using a loop to make the processor wait a while. The compiler is free to generate any kind of code, it might even remove it completely if it can determine that it doesn't perform any action.

    Instead, you can use the intrinsic function __delay_cycles, it inserts assembly code that takes an exact number of cycles to run. Of course, for long delays, you could also consider putting the processor into low-power mode and wake it using a timer.
