  2004-05-21  Jim Blandy  <jimb at redhat.com>
  
         * dwarf2expr.c (execute_stack_op): Add 'break' statements after
         cases for DW_OP_div and DW_OP_shr.  (Thanks to Reva Cuthbertson.)
  
  GDB: Replace use of sprintf.
  
  2005-03-17  Mark Kettenis  <kettenis at gnu.org>
  
        * corelow.c (get_core_register_section): Replace usage of sprintf
        and strcpy with xstrprintf and xstrdup.
