Miscellaneous-NoImplicitTypeConversion

Do not use implicit type conversions

Required inputs: IR

This rule will warn on every use of implicit type conversions.

C performs implicit type conversions in many places, e.g. numeric promotion whenever an operator is applied to a type smaller than int.

This makes it nearly impossible to avoid all implicit conversions, so this rule is not very useful. Consider using the MisraC2012 rules 10.* and MisraC2012 rules 11.* instead to prevent problematic implicit type conversions.
