This is a follow up on an email I send out earlier wrt to list command not
able to output correct information. The list command does not see the
debug infomation in the case of fortran programs?? I have below a senario
on a PPC64 machine.


I compiled a simple hello world program in fortran

--------------------- hellow.f ---------------------
*
C Hello world program
*
      PROGRAM HELLOW
      WRITE(UNIT=*, FMT=*) 'Hello World'
      END
----------------------------------------------------

g77 -g -m64 -o hellowf hellow.f

manjo@nefertiti:~/projects/src> ./gdb/gdb ~/tests/hellow

directory.
        in ../sysdeps/powerpc/powerpc64/elf/start.S
(gdb)


In the above case, the list command does not see the debug information
even if the program is compiled with "-g" option.

The same program when written in C

-------------------------- test.c --------------------------
#include <stdio.h>

main()
{
    printf("hello world\n");
}
-------------------------------------------------------------

cc -g -m64 -o test test.c

2
3       main()
4       {
5           printf("hello world\n");
6       }
7
(gdb) quit

Which is the correct output for the list command.


Any thoughts??
