I can interpret the source code example in the way that the number of set bits are checked. I can eventually become concerned around the preferred coding style because of the usage of these constant values. Would you like to check the use of bit fields? >> * Where do you stumble on difficulties to express a corresponding source code >> search pattern by the means of the semantic patch language? > > #defines, shifts, masks You come along the usual development challenges for the safe handling of possible code variations. With which approach would you like to start and perform further source code analysis?
