Reports shift operations where the value shifted by is constant and outside of the reasonable range. Integer shift operations outside of the range 0..31 and long shift operations outside of the range 0..63 are reported. Shifting by negative or overly large values is almost certainly a coding error.

Example:

  int shiftSize = 32;
  // Warning: shift by 32 bits is equivalent to shift by 0 bits, so there's no shift at all. 
  int mask = (1 << shiftSize) - 1;
