 Finds uses of bitwise operations on signed integer types, which may lead to
 undefined or implementation defined behavior.
 
+Performing bitwise operations on signed integers can be confusing and may
+lead to undefined or implementation dependent behavior. In particular, right

+integer may result in undefined behavior.
