From 89a85a6603b7112e685a052d728284d3e4c2881e Mon Sep 17 00:00:00 2001 From: Gaëtan Gilbert Date: Fri, 11 May 2018 23:07:14 +0200 Subject: Fix #7421: constr_eq ignores universe constraints. The test isn't quite the one in #7421 because that use of algebraic universes is wrong. --- engine/evd.ml | 3 +++ engine/evd.mli | 2 ++ 2 files changed, 5 insertions(+) (limited to 'engine') diff --git a/engine/evd.ml b/engine/evd.ml index 0c9c3a29b..f56f9662d 100644 --- a/engine/evd.ml +++ b/engine/evd.ml @@ -894,6 +894,9 @@ let check_eq evd s s' = let check_leq evd s s' = UGraph.check_leq (UState.ugraph evd.universes) s s' +let check_constraints evd csts = + UGraph.check_constraints csts (UState.ugraph evd.universes) + let fix_undefined_variables evd = { evd with universes = UState.fix_undefined_variables evd.universes } diff --git a/engine/evd.mli b/engine/evd.mli index c40e925d8..405fcc403 100644 --- a/engine/evd.mli +++ b/engine/evd.mli @@ -552,6 +552,8 @@ val set_eq_instances : ?flex:bool -> val check_eq : evar_map -> Univ.Universe.t -> Univ.Universe.t -> bool val check_leq : evar_map -> Univ.Universe.t -> Univ.Universe.t -> bool +val check_constraints : evar_map -> Univ.Constraint.t -> bool + val evar_universe_context : evar_map -> UState.t val universe_context_set : evar_map -> Univ.ContextSet.t val universe_subst : evar_map -> UnivSubst.universe_opt_subst -- cgit v1.2.3
