No. See pass_free_cfg,

Are these invalid code generators then? Or are we talking about
different things?

The very first thing that ia64_reorg does is
compute_bb_for_insn ();
Just taking a quick look, I don't see any bb

Hi!
I inspect code after branch delay slot scheduling by dumping the
insn-list to a VCG-file:
for(insn = get_insns(), NULL_RTX != insn; insn = NEXT_INSN(insn))
dump_insn_and_prev_and_next(insn);
FOR_EACH(bb) dump_bb_and_head_and_end(bb)
But some basic blocks seem to point to insns which

No. See pass_free_cfg, which is the third pass before pass_delay_slots.
