* Evar maps contain econstrs.Gravatar Gaëtan Gilbert2018-04-13
| | | | | | We bootstrap the circular evar_map <-> econstr dependency by moving the internal EConstr.API module to Evd.MiniEConstr. Then we make the Evd functions use econstr.

| | * Delayed weak constraints for cumulative inductive types.Gravatar Gaëtan Gilbert2018-03-09
| | | | | | | | | | | | | | | | | | | | | When comparing 2 irrelevant universes [u] and [v] we add a "weak constraint" [UWeak(u,v)] to the UState. Then at minimization time a weak constraint between unrelated universes where one is flexible causes them to be unified.

| | * Cumulativity: improve treatment of irrelevant universes.Gravatar Gaëtan Gilbert2018-03-09
| | | | | | | | | | | | | | | | | | In Reductionops.infer_conv we did not have enough information to properly try to unify irrelevant universes. This requires changing the Reduction.universe_compare type a bit.
| | * Allow using cumulativity without forcing strict constraints.Gravatar Gaëtan Gilbert2018-03-09
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | [compat] Remove "Refolding Reduction" option.Gravatar Emilio Jesus Gallego Arias2018-03-08

Even typing functions were not ported to Sigma. - Some unsafe combinators (Unsafe.tclEVARS) were replaced with slightly less unsafe ones (e.g. s_enter), but those ones were not marked unsafe at all (despite still being so). - There was no good story for higher order functions manipulating evar maps. Without higher order, one can most of the time get away with reusing the same name for the updated evar map. - Most of the code doing complex things with evar maps was using unsafe casts to sigma. This code should be fixed, but this is an orthogonal issue. Of course, this was showing a nice and elegant use of GADTs, but the cost/benefit ratio in practice did not seem good.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This exports two functions: - declare_reduction_effect: to declare a hook to be applied when some constant are visited during the execution of some reduction functions (primarily cbv, but also cbn, simpl, hnf, ...). - set_reduction_effect: to declare a constant on which a given effect hook should be called. Developed jointly by Thomas Sibut-Pinote and Hugo Herbelin. Added support for printing effect in functions of tacred.ml.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the continuation of #244, we now deprecate `CErrors.error`, the single entry point in Coq is `user_err`. The rationale is to allow for easier grepping, and to ease a future cleanup of error messages. In particular, we would like to systematically classify all error messages raised by Coq and be sure they are properly documented. We restore the two functions removed in #244 to improve compatibility, but mark them deprecated.
* | | [option] Remove support for non-synchronous options.Gravatar Emilio Jesus Gallego Arias2017-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspired by https://coq.inria.fr/bugs/show_bug.cgi?id=5229 , which this PR solves, I propose to remove support for non-synchronous options. It seems the few uses of `optsync = false` we legacy and shouldn't have any impact. Moreover, non synchronous options may create particularly tricky situations as for instance, they won't be propagated to workers.
