2018-10-31No need to require List in test-suite/success/Inductive.vGaëtan Gilbert
Requires are slow in the debugger so removing this makes it nicer to debug.

2017-09-23Fixing _rect bug for inductive types with let-ins and non-rec uniform params.Hugo Herbelin
The bug was caused by an inconsistency in different part of the code for deciding where cutting the context in between recursively uniform parameters and non-recursively uniform ones when let-ins were in the middle. We fix it by using uniformly "context_chop".
2016-11-30Fix UGraph.check_eq!Matthieu Sozeau
Universes are kept in normal form w.r.t. equality but not the <= relation, so the previous check worked almost always but was actually too strict! In cases like (max(Set,u) = u) when u is declared >= Set it was failing to find an equality. Applying the KISS principle: u = v <-> u <= v /\ v <= u. Fix invariant breakage that triggered the discovery of the check_eq bug as well. No algebraic universes should appear in a term position (on the left of a colon in a typing judgment), this was not the case when an algebraic universe instantiated an evar that appeared in the term. We force their universe variable status to change in refresh_universes to avoid this. Fix ind sort inference: Use syntactic universe equality for inductive sort inference instead of check_leq (which now correctly takes constraints into account) and simplify code
2015-03-25Fully fixing bug #3491 (anomaly when building _rect scheme in theHugo Herbelin
presence of let-ins and recursively non-uniform parameters). The bug was in the List.chop of Inductiveops.get_arity which was wrong in the presence of let-ins and recursively non-uniform parameters. The bug #3491 showed up because, in addition to have let-ins, it was wrongly detected as having recursively non-uniform parameters. Also added some comments in declarations.mli.
2015-03-25Another example about the consequence of a wrong computation of theHugo Herbelin
number of recursively uniform parameters in the presence of let-ins. In practice, more recursively non-uniform parameters were assumed and this was used especially for checking positivity of nested types, leading to refusing more nested types than necessary (see Inductive.v).

presence of let-ins. This fixes #3491.
2015-03-24Fixing wrong rel_context in checking positivity condition.Hugo Herbelin
Parameters were missing in the context, apparently without negative effects because the context was used only for whd normalization of types, while reduction (in closure.ml) was resistant to unbound rels. See however next commit for an indirect effect on the wrong computation of non recursively uniform parameters producing an anomaly when computing _rect schemas.

2009-08-11Ensures that let-in's in arities of inductive types work well. Maybe notherbelin
very useful in practice but as soon as let-in's were not forbidden in the internal data structure, better to do it.
