Hi Paul,
I thought that the suggestion to add the original input lines was not bad. It would be even better if -fdump-tree-original could do that. I often time find myself putting a line under the spotlight in a contained subroutine.
This should be doable. What should be the perferred format? Something like filename:line\tOutput goes here would be possible, or without the file name line\tOutput goes here The latter would have the advantage that it would be fairly easy to line up the declarations from modules, which probably should not have line number annotations. And what would be preferred - having a new option to control line numbering, or doing it unconditionally? Regards Thomas
