Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |enhancement --- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- We have in evrp: Registering value_relation (b_2(D) >= a_3(D)) on (2->4) ... Relational : (b_2(D) >= a_3(D)) <bb 4> : if (a_3(D) < 0) goto <bb 5>; [INV] else goto <bb 6>; [INV] 4->5 (T) a_3(D) : int [-INF, -1] 4->6 (F) a_3(D) : int [0, +INF] But then we don't update the value relationship for what we had for b_2 for the branch where a_3 >= 0, we should also a range for b_2(D) of [0, +INF] for 4->6.
