Is app.exe stripped or in some other format that doesn't include symbols?

Has the .exe been moved from its build location?  Sometimes you have to
tell objdump (and gdb) where the real source is located.  Use the --source
option.

I use objdump to do what you are doing and it does work.  Here's an example
fragment:

RTEMS_INLINE_ROUTINE void _Chain_Initialize_empty(
  Chain_Control *the_chain
)
{
  the_chain->first          = _Chain_Tail(the_chain);
 2003a00:       c2 20 7f fc     st  %g1, [ %g1 + -4 ]
 2003a04:       82 00 7f fc     add  %g1, -4, %g1
  the_chain->permanent_null = NULL;
  the_chain->last           = _Chain_Head(the_chain);
 2003a08:       c2 20 60 08     st  %g1, [ %g1 + 8 ]
