--- Comment #13 from Tom de Vries <vries at gcc dot gnu.org> --- Created attachment 41216 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41216&action=edit updated script patch This updated patch rewrites a line from absolute to relative linenumber if: - the relative line number is '.-1', '.' or '.+1', or - it's adjacent to a line we will rewrite (with the line numbers being consecutive) The biggest relative line number generated by the script is 6.
