| Axivion Bauhaus Suite |
| CertC-INT34 | Can detect shifts by a negative or an excessive number of bits and right shifts on negative values. | ||||||
| CodeSonar |
| LANG.ARITH.BIGSHIFT | Shift amount exceeds bit width | ||||||
| Compass/ROSE | Can detect violations of this rule. Unsigned operands are detected when checking for INT13-C. Use bitwise operators only on unsigned operands | ||||||||

| Cppcheck |
| shiftNegative, shiftTooManyBits | Context sensitive analysis | ||||||
| Cppcheck Premium |
| shiftNegative, shiftTooManyBits premium-cert-int34-c | Context sensitive analysis Warns whenever Cppcheck sees a negative shift for a POD expression (The warning for shifting too many bits is written only if Cppcheck has sufficient type information and you use --platform to specify the sizes of the standard types.) | ||||||
