--- Comment #20 from Jan Hubicka <hubicka at gcc dot gnu.org> --- H.J. Can you, please attach the full .cp dump file and release_ssa dump of the corresponding functions? The -fipa-cp-alignment patch looks like a resonable idea. These days you want to check opt_for_fn (decl, flag_ipa_cp_alignment). Ok with that change and documentation update. Honza
