meaning of this objdump output?

[Phil Edwards <pedwards at disaster dot jaj dot com>]

The output of objdump -t is documented to be "similar to the information
provided by the `nm' program."  Except that it isn't.  Reading through
the code, '-t' forwards to bfd_print_symbol(), which is a macro wrapper
around something horrible.  :-)  That's where I gave up.

For example,

    47% nm -C libstdc++.so | grep S_free_list
    0009d640 B std::__default_alloc_template<true, 0>::_S_free_list
    48%

nm's documentation explains to me (and more importantly, my coworkers!) what
the B means.  No problems there, nm is a common tool.

But this output

    49% objdump -t -C -j .bss libstdc++.so | grep _S_free_list
    0009d640 g     O .bss   00000080              std::__de[ trim long name ]
    50%

isn't similar, doesn't correspond, and isn't documented.  My coworkers
could figure out the address field (obvious), and the ".bss" and "00000080"
fields were obvious to me, but none of us can tell what the "g" and "O" are.

Anyone give us a hand?


Thanks for your time,
Phil
