        * gcov.c (add_line_counts): Assign BBs to lines just if the BB
        is marked by compiler as living on a line.
        (get_cycles_count): Remove usage of the union.
        (output_intermediate_file): Likewise.
        (find_source): Fix GNU coding style.
        (accumulate_line_counts): Remove old non-all block mode.
        (output_lines): Remove usage of the union.
        * profile.c (output_location): Include all BBs, even if
        belonging to a same line (and file) as a previous BB.
