teemperor updated this revision to Diff 68556.
teemperor added a comment.
- Added more documentation to the CloneSignature::Complexity field.
- Macros now have a complexity value of 1 + sum(ChildComplexityValues).
- Tests should be less cryptic now.

Do I understand correctly that a code generated by a macro doesn't affect
"complexity" at all then?
v.g.vassilev added inline comments.
