--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think the RTTI "names" merely need to be unique (but maybe the C++ frontend
emits them elsewhere as well, like for direct compares?), so replacing them
globally (covering all RTTI interactions in the programs/shlibs involved)
with minimum size 1:1 mappings should be possible. Not sure how to do this,
possibly LTO could be used for all RTTI data that doesn't "escape" the
unit? Post-processing all binaries/libraries in a system is probably not
easily possible.
