--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'll note the testcase no longer exhibits large number of antic iterations:
Pass statistics of "pre": ----------------
RPO blocks: 3610
insert iterations == 2: 1
compute_antic iterations == 2: 1
not even with -O1 -fno-thread-jumps -fno-tree-pre
I'm not working on this, the assert, now with checking enabled only, still
catches non-convergent dataflow, so it's useful.
