Yes, they are symbols that are not referenced by other objects. In fact, I believe you'll find in the case of each of these symbols that *every* binary on the given architecture includes their own copy of these symbols, including executables as well as libraries. > That exclude list will still have to be maintained over the years I think > since the list will probably evolve. Hopefully it will evolve with negative magnitude, so we get fewer such symbols over the years rather than more of them. :) I've seen other people opine before, and I agree, that these extra exported symbols ought to be considered bugs in the toolchain, and ought to eventually be removed from the export list. > I'm checking for example on a powerpc machine: [...] > So it looks like those symbols are defined in each and every binary. > But the programs do not rely on the same symbols from the libraries. > Thus it seems fine to exclude them from the symbols files. Yep. Cheers, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
