https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71084 --- Comment #4 from Ilya Enkovich --- This is still CSE invalidating dominance info. Calls to cleanup_cfg don't affect cse_cfg_altered. If I replace cfg_cleanup calls with cse_cfg_altered |= cleanup_cfg (..) then testcase passes.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71084 --- Comment #3 from Richard Biener --- fwprop_init calcuates dominator info so it's likely df that runs cfg-cleanup and doesn't expect it to wreck dominator info. Probably rightfully so.
