2018-06-27Swapping Context and Constr: defining declarations on constr in Constr.Hugo Herbelin
This shall eventually allow to use contexts of declarations in the definition of the "Case" constructor. Basically, this means that Constr now includes Context and that the "t" types of Context which were specialized on constr are not defined in Constr (unfortunately using a heavy boilerplate).

2018-05-04[api] Rename `global_reference` to `GlobRef.t` to follow kernel style.Emilio Jesus Gallego Arias
In #6092, `global_reference` was moved to `kernel`. It makes sense to go further and use the current kernel style for names. This has a good effect on the dependency graph, as some core modules don't depend on library anymore. A question about providing equality for the GloRef module remains, as there are two different notions of equality for constants. In that sense, `KerPair` seems suspicious and at some point it should be looked at.

2018-03-09Allow using cumulativity without forcing strict constraints.Gaëtan Gilbert
Previously [fun x : Ind@{i} => x : Ind@{j}] with Ind some cumulative inductive would try to generate a constraint [i = j] and use cumulativity only if this resulted in an inconsistency. This is confusingly different from the behaviour with [Type] and means cumulativity can only be used to lift between universes related by strict inequalities. (This isn't a kernel restriction so there might be some workaround to send the kernel the right constraints, but not in a nice way.) See modified test for more details of what is now possible. Technical notes: When universe constraints were inferred by comparing the shape of terms without reduction, cumulativity was not used and so too-strict equality constraints were generated. Then in order to use cumulativity we had to make this comparison fail to fall back to full conversion. When unifiying 2 instances of a cumulative inductive type, if there are any Irrelevant universes we try to unify them if they are flexible.

2018-01-26Safer VM interfacesMaxime Dénès
We separate functions dealing with VM values (vmvalues.ml) and interfaces of the bytecode interpreter (vm.ml). Only the former relies on untyped constructions. This also makes the VM architecture closer to the one of native_compute, another patch could probably try to share more code between the two for conversion and reification (not trivial, though). This is also preliminary work for integers and arrays.

Extending terms is notoriously difficult. We try to get more help from the compiler by making sure such an extension will trigger non exhaustive pattern matching warnings.
2017-11-22[api] Deprecate Term destructors, move to ConstrEmilio Jesus Gallego Arias
We mirror the structure of EConstr and move the destructors from `Term` to `Constr`. This is a step towards having a single module for `Constr`.

2014-10-20A patch for printing "match" when constructors are defined with let-inHugo Herbelin
but the internal representation dropped let-in. Ideally, the internal representation of the "match" should use contexts for the predicate and the branches. This would however be a rather significant change. In the meantime, just a hack. To do, there is still an extra @ in the constructor name that does not need to be there.

2014-06-06Make kernel reduction code parametric over the handling of universes,Matthieu Sozeau
allowing fast conversion to be used during unification while respecting the semantics of unification w.r.t universes. - Inside kernel, checked_conv is used mainly, it just does checking, while infer_conv is used for module subtyping. - Outside, infer_conv is wrapped in Reductionops to register the right constraints in an evarmap. - In univ, add a flag to universes to cache the fact that they are >= Set, the most common constraints, resulting in an 4x speedup in some cases (e.g. HigmanS).
