* Fix #7333: vm_compute segfaults / Anomaly with cofixGravatar Maxime Dénès2018-05-28

* | [api] Rename `global_reference` to `GlobRef.t` to follow kernel style.Gravatar Emilio Jesus Gallego Arias2018-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * Adapt the VM GC hook to handle the no-naked-pointers option flag.Gravatar Pierre-Marie Pédrot2018-04-30
| | | | | | | | | | | | | | The Coq VM stack is scanned by the OCaml GC, but it can contain raw pointers to C-allocated strings standing for VM bytecode. If the the no-naked-pointers option is set, we perform the check that a stack value lives on the OCaml heap ourselves.
| * Make the VM accumulator look like an OCaml block.Gravatar Pierre-Marie Pédrot2018-04-30
| | | | | | | | | | | | We allocate an additional header so that the accumulator is not a naked pointer. Indeed, it is contained in accumulator blocks which are scanned by the GC as their tags is 0.
| * Wrap VM bytecode used on the OCaml side in an OCaml block.Gravatar Pierre-Marie Pédrot2018-04-30
|/ | | | | | | | | | This prevents the existence of a few naked pointers to C heap from the OCaml heap. VM bytecode is represented as any block of size at least 1 whose first field points to a C-allocated string. This representation is compatible with the Coq VM representation of (potentially recursive) closures, which are already specifically tailored in the OCaml GC to be able to contain out-of-heap data.

* | | Always print explanation for univ inconsistency, rm Flags.univ_printGravatar Gaëtan Gilbert2018-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the Flags.univ_print in the kernel, making it possible to put the univ printing flag ownership back in Detyping. The lazyness is because getting an explanation may be costly and we may discard it without printing. See benches - with lazy https://ci.inria.fr/coq/view/benchmarking/job/benchmark-part-of-the-branch/406/console - without lazy https://ci.inria.fr/coq/view/benchmarking/job/benchmark-part-of-the-branch/405/console Notably without lazy mathcomp odd_order is +1.26% with some lines showing significant changes, eg PFsection11 line 874 goes from 11.76s to 13.23s (+12%). (with lazy the same development has -1% overall and the same line goes from 11.76s to 11.23s (-4%) which may be within noise range)

* Fix expected number of arguments for cumulative constructors.Gravatar Gaëtan Gilbert2018-03-09
| | | | | | | We expected `nparams + nrealargs + consnrealargs` but the `nrealargs` should not be there. This breaks cumulativity of constructors for any inductive with indices (so records still work, explaining why the test case in #6747 works).

| | * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We limit fixpoints to Finite inductive types, so that BiFinite inductives (non-recursive records) are excluded from fixpoint construction. This is a regression in the sense that e.g. fixpoints on unit records were allowed before. Primitive records with eta-conversion are included in the BiFinite types. Fix deprecation Fix error message, the inductive type needs to be recursive for fix to work
