Darn.

objdump -W <file>

objdump -WL <file>

I doubt if this is the same as oprofile will produce, but both tools
will be displaying processed DWARF line number information so they
should be roughly equivalent.  You can also use "objdump -Wl <file>"
(with a lowercase-l rather than an uppercase-L) to see the raw DWARF
debug line information.

Cheers
