Hi all,
this series aims to refactor some macros that cause violations of MISRA C Rule
20.7 ("Expressions resulting from the expansion of macro parameters shall be
enclosed in parentheses"). All the macros touched by these patches are in some
way involved in violations, and the strategy adopted to bring them into
compliance is to add parentheses around macro arguments where needed.
Given that the community has previously requested a deviation from the rule, as
stated in docs/misra/deviations.rst, and reported below for convenience [1],
some macro parameters do not need any adjusting (e.g., when used as lhs to
an assignment in statement expressions).
Note that the patch on list.h of the earlier series [2] has been intentionally
left out of this series, because it still needs some adjustments.
[1] - Code violating Rule 20.7 is safe when macro parameters are used:
(1) as function arguments;
(2) as macro arguments;
(3) as array indices;
(4) as lhs in assignments.
