Enable -Wshift-overflow=2 to check for undefined shift behavior
The -Wshift-overflow=2 option enables checks for left bit shifts. Specifically, the option will warn when the result of a shift will be placed into a signed integer and overflow the sign bit there, which results in undefined behavior. To avoid the warnings from these checks, the left operand of a shift can be made an unsigned integer by using the U() macro or appending the u suffix.
