frame information missing

["nagaraju.m" <nagaraju dot m at redpinesignals dot com>]

Hi,
  
   I have recently ported gdb-6.8. I took frv as reference for my 
*-tdep file. Every thing is working fine but,

      Whenever a function is called it is printing whole stack instead 
of printing function arguments..

 *consider the following simple program*

int add(int a,int b)
{
   return (a+b);
}

int main()
{
        int a=10,b=20;
        b = add(a,b);
}
                                 
*     GDB Behaviour*

(gdb)

(gdb)
main () at add.c:10
10      }
(gdb) p b
$1 = 30

can any one please suggest where should i give frame boundaries.

Thanks,
