xor package:what4
Provides an implementation of bitvector abstract domains optimized for
performing XOR operations.
Bitwise logical exclusive or.
Bitvector exclusive or of all arguments.
Bitwise logical exclusive or.
BVDXor mask hi unknown represents a set of values where
hi is a bitwise high bound, and unknown represents
the bits whose values are not known. The value mask caches
the value 2^w-1.
