...
Most legitimate platform dependencies can and should be isolated in separate modules that use portable interfaces but platform-specific implementations.
Non-Compliant
...
Code Example
This non-compliant coding code example used uses the complement operator in the test for unsigned integer overflow.
...
If the non-compliant form of this test is truly faster, talk to your compiler vendor, because if these tests are equivalent then optimization should occur. If both forms have the same performance, prefer the portable form.
Risk Assessment
Unused values may indicate significant logic errors, possibly resulting in a denial of service conditionUnnecessary platform dependencies are, by definition, unnecessary. Avoiding these dependencies can eliminate porting errors resulting from invalidated assumptions.
