--- Comment #47 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 42873 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42873&action=edit gcc8-pr83396-ia64.patch So what about this for the ia64 issue? Rather than trying to force sanity into the ia64 port, just keep what we've been doing except for DEBUG_INSNs, i.e. process other insns only from BB_HEAD to BB_END, the rest only care about DEBUG_INSNs and from those assert it isn't debug bind.
