We see that there is one partial symbol table whose filename contains
the string @samp{dwarf2read}, belonging to the @samp{gdb} executable;
and we see that @value{GDBN} has not read in any symtabs yet at all.
If we set a breakpoint on a function, that will cause @value{GDBN} to
read the symtab for the compilation unit containing that function:
@smallexample
