Re: identify unused functions?

[Stefan Kost <ensonic hora-obscura de>]

Hi,

nm --undefined-only *.o | cut -c12- | sort | uniq
would give you a list of all external symbols

nm --defined-only *.o | cut -c12- | sort | uniq
would give you a list of all defined symbols

now all enties in 2nd list, which are not in first list should be what you are 
looking for ('comm' should be able to do that).
