2020-11-15Fixes #12348: long-standing de Bruijn indices bug in imitation ↵Hugo Herbelin
(solve_simple_eqn). The bug was that an assumption could be interpreted as a local definition and wrongly expanded. It triggered rarely because it involved mixing let-ins and local assumptions + imitation under binders.

2020-11-13Fixes #13363: case of a meta not paying attention to being under binders.Hugo Herbelin
In Evar := C[Meta] problems of unification.ml, and C[ ] contains binders, Meta was wrongly considered by pose_all_metas_as_evars as under these binders (while Metas are always defined in the initial context of the unification problem).
2020-11-13Make the universe of primitive arrays irrelevantGaëtan Gilbert
Fix #13354 This change is very specific to array, but should not be a significant obstacle to generalization of the feature to eg axioms if we want to later.

2020-11-09Remove the native symbol registering from the safe environment.Pierre-Marie Pédrot
Instead we store that data in the native code that was generated in adapt the compilation scheme accordingly. Less indirections and less imperative tinkering makes the code safer. The global symbol table was originally introduced in #10359 as a way not to depend on the Global module in the generated code. By storing all the native-related information in the cmxs file itself, this PR also makes other changes easier, such as e.g. #13287.

Also some dead code. If no typo is introduced, there should be no semantic changes.
2020-10-31Closes #13278: take into account elimination constraints in small inversion.Hugo Herbelin
Ideally, if equations t <= ?x were preserving subtyping that could be simpler. Currently we need however to put a rigid universe as constraint on the return predicate so that one branch does not force the return sort to be lower by unification than what another branch would have needed.
2020-10-31Fine-tuning the sort of the predicate obtained by small inversion.Hugo Herbelin
If the result is in SProp, Prop or (impredicative) Set, we preserve this information since the elimination sort might be restricted by the sort of the destructed type. If the result is in Type, we use a fresh sort upper bound so that we are sure not having residual algebraic universes which would raise problems in a type constraint (e.g. in define_evar_as_product). This fixes the part of #13278 posted on discourse.
