Code Inspection: Incompatible bitwise mask operation

Reports a bitwise mask expression which for sure evaluates to true or false and . Expressions are of the form (var & constant1) == constant2 or (var | constant1) == constant2, where constant1 and constant2 are incompatible bitmask constants.

Example:

// Incompatible mask: as the last byte in mask is zero, // something like 0x1200 would be possible, but not 0x1234 if ((mask & 0xFF00) == 0x1234) {...}
