* Adding a sanity check on inductive variance subtyping.Gravatar Pierre-Marie Pédrot2018-02-15

* Simplification: cumulativity information is variance information.Gravatar Gaëtan Gilbert2018-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | Since cumulativity of an inductive type is the universe constraints which make a term convertible with its universe-renamed copy, the only constraints we can get are between a universe and its copy. As such we do not need to be able to represent arbitrary constraints between universes and copied universes in a double-sized ucontext, instead we can just keep around an array describing whether a bound universe is covariant, invariant or irrelevant (CIC has no contravariant conversion rule). Printing is fairly obtuse and should be improved: when we print the CumulativityInfo we add marks to the universes of the instance: = for invariant, + for covariant and * for irrelevant. ie Record Foo@{i j k} := { foo : Type@{i} -> Type@{j} }. Print Foo. gives Cumulative Record Foo : Type@{max(i+1, j+1)} := Build_Foo { foo : Type@{i} -> Type@{j} } (* =i +j *k |= *)
* Moving some universe substitution code out of the kernel.Gravatar Pierre-Marie Pédrot2017-12-30
| | | | | | This code was not used at all inside the kernel, it was related to universe unification that happens in the upper layer. It makes more sense to put it somewhere upper.
* Do not hashcons universes beforehand.Gravatar Pierre-Marie Pédrot2017-09-01
| | | | | This should save a lot of useless reallocations and hashset crawling, which end up costing a lot.

* Fixing the checker w.r.t. wrongly used abstract universe contexts.Gravatar Pierre-Marie Pédrot2017-07-19
| | | | | | | | | | | It seems we were not testing the checker on cumulative inductive types, because judging from the code, it would just have exploded in anomalies. Before this patch, the checker was mixing De Bruijn indices with named variables, resulting in ill-formed universe contexts used throughout the checking of cumulative inductive types. This patch also gets rid of a lot of now dead code, and removes abstraction breaking code from the checker.
* Properly handling polymorphic inductive subtyping in the checker.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | This is the followup of the previous commit, this time implementing the correct algorithm in the checker.
* Less footguns in universe handling: remove subst_instance_context.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | This function was lurking around, waiting to bite anybody willing to use it. We use instead a better API, correct and much less error-prone.
* Getting rid of simple calls to AUContext.instance.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | | This function breaks the abstraction barrier of abstract universe contexts, as it provides a way to observe the bound names of such a context. We remove all the uses that can be easily get rid of with the current API.
