The condition was introduced in r267142 to mitigate a long compile-time case. In r306087, a max-computation limit was introduced that should handle the same case while leaving the max disjuncts heuristic it should have replaced intact. Today, the max disjuncts bail-out causes problems in that it prematurely stops SCoPs from being detected, e.g. in SPEC's lbm. This would hit less like if isl_set_coalesce would be called after isl_set_remove_divs (which makes more basic_set likely to be coalescable) instead of before. This patch tries to remove the premature max-disjuncts bail-out condition by using simple_hull() to reduce the computational overhead, instead of directly invalidating that SCoP.
