Hi,

	I am facing problem while using gdb-6.7.50_20070918.
When I used command like:

$xc16x-elf-gdb app1.out

I get the following error message:

I'm sorry, Dave, I can't do that.  Symbol format 'elf32-xc16x' unknown.



I traced and modified find_sym_fns()in symfile.c just for testing purpose as follows:


static struct sym_fns *
find_sym_fns (bfd *abfd)
{
  struct sym_fns *sf;
  enum bfd_flavour our_flavour = bfd_get_flavour (abfd);

  enum bfd_flavour test_flavour;  /* create one bfd_flavour instance for 						test purpose */

  if (our_flavour == bfd_target_srec_flavour
      || our_flavour == bfd_target_ihex_flavour
      || our_flavour == bfd_target_tekhex_flavour)
    return NULL;	/* No symbols.  */

  for (sf = symtab_fns; sf != NULL; sf = sf->next)
  {
	  test_flavour = sf->sym_flavour;
	  printf_unfiltered (_("test_flavour %d.. our flavour  %d...\n"), test_flavour,our_flavour);  /* print tested values */
    //if (our_flavour == sf->sym_flavour)
    //return sf;
  }
  error (_("I'm sorry, Dave, I can't do that.  Symbol format `%s' unknown."),
	 bfd_get_target (abfd));
}


And got the following output :

test_flavour 3.. our flavour  5...
test_flavour 2.. our flavour  5...
test_flavour 1.. our flavour  5...
I'm sorry, Dave, I can't do that.  Symbol format 'elf32-xc16x' unknown.

Here the loop is iterated only for 3 times. however in gdb-6.4 (after making the same changes in find_sym_fns()function in symfile.c I got different output as :

test_flavour 5.. our flavour  5...
test_flavour 4.. our flavour  5...
test_flavour 3.. our flavour  5...
test_flavour 2.. our flavour  5...
test_flavour 1.. our flavour  5...

in this case the loop iterated 5 times giving correct expected output.

I am not getting the reason why this is happening in case of
gdb 6.7.50_20070918.
What are the possible reasons to this problems?
And what changes or additions I need to do?

Any help appreciated.
Thanking you in advance.
