Note: For compliance purposes, there is no distinction between rules and directives. Most of the guidelines can be checked using tools that perform. They are separately classified as either Single Translation Unit or System. Rule Definition Widespread use of the guidelines over a number of years has clearly provided valuable feedback from the user community. For the Engineer writing in C, designing a safe program not only demands that the program run as it was designed to, the program must also run correctly when ported to a different environment and, just as important, the source code must be very clearly written for others that may read it later.

The remaining guidelines require the use of. Rules are now better defined, explained, and justified to address areas where there was some confusion. Additionally, the rules are classified as Decidable or Undecidable. The true positive rates for these rules range from 24-100%. .

In addition, 29 out of 72 rules had a zero true positive rate. Advisory rules may be disapplied without a formal deviation, but this should still be recorded in the project documentation. If a rule is undecidable, it will not be possible for a tool to guarantee compliance in all circumstances however sophisticated the analysis techniques may be. Unfortunately it had also introduced a range of new hazards. At the time this made sense, with few compilers offering support for C99, and even fewer projects using the new standard C11.

There were several reasons, including strong support for C99, responding to user feedback, and an acknowledgement that improvements could be made. It comes to similar results: From the data obtained, we can make the following key observations. The rapidly increasing reliance on software is focusing more and more attention on the critical importance of ensuring reliability. Rule Enforceability A characteristic of prime importance for any coding rule is the extent to which it can be enforced using static analysis: a rule that cannot be enforced automatically requires expensive and time-consuming manual code reviews to ensure compliance. If a rule is decidable, it should be possible, in theory, for an analysis tool to decide unequivocally whether the rule has been violated or not.

This will reduce potential problems when, and if, the software is further developed. Previous standards are still available for use with legacy software projects that need to refer to it. Rule Classification In the past, rules were classified as either Advisory or Required. Deviations must be documented either in the code or in a file. Rules are precisely defined and can be enforced solely by analysis of the source code; but compliance with directives may require reference to design documentation, functional requirements, or some degree of subjective judgment or interpretation. .
