Thank you,
can you, please, check that the problem appears still after
2013-12-17 Jan Hubicka <hubi...@ucw.cz>
* ipa-utils.h (possible_polymorphic_call_targets): Determine context of
the call.
* gimple-fold.c (gimple_fold_call): Use ipa-devirt to devirtualize.
this patch makes early passes to use same analysis for devirtualization as IPA
passes and thus it should prevent from devirtualization to be discovered just
after early passes but before IPA analysis. I suspect those can bring LTO
streaming out of sync. If this is the case, we need to chase away the
unreachable code removal that should not be placed in between renumbering stmts
and streaming.
