In case of declarations and function calls we need to carry over comments from the statement's source location into individual subexpressions as the source location of those subexpressions will be used when generating the goto program instruction.

There was a problem hiding this comment.
If the comment is non empty, should we merge instead of ignoring?

The new implementation in #4666 also resolves this problem (in parts by just removing the above code :-) ).

I will merge this now, but will also explore a cleaner solution that doesn't abuse comments and instead has dedicated annotations. Then "merging" will actually be possible as the semantics of those annotations can be clearly defined. |
