Compass/ROSE



Could detect violations of this recommendation by searching for the following pattern:

    • Any expression that calls two functions between the same sequence points
    • Those two functions both modify the value of a static variable
    • That static variable's value is referenced by code following the expression

EVALUATION_ORDER

Can detect the specific instance where a statement contains multiple side effects on the same value with an undefined evaluation order because the statement may behave differently with different compiler flags or different compilers or platforms

The value of an expression shall be the same under any order of evaluation that the standard permits
Don't write code that depends on the order of evaluation of function arguments
Don't write code that depends on the order of evaluation of function designator and function arguments

A programmer could also violate the recommendation using dynamic memory passed to both functions, but that would be extremely difficult to detect using static analysis.
