/* This file contains some basic DWARF info.  The only particularity about
   this info is that this compile unit does not have a DW_AT_producer
   attribute.  The rest is a straight copy of one of the other assembly
   files available in this directory.

   The intent of this testcase is to verify that GDB is able to handle
   the lack of the DW_AT_producer attribute without problem.  */
