Also fold it into `Z.div_mod_to_quot_rem` Note that the test-suite file is a bit slow. On my machine, it is ``` real 2m32.983s user 2m32.544s sys 0m0.492s ```
2019-01-24Don't bundle Z.div_mod_quot_rem into zifyJason Gross
Alas, I have not had time to work on imrpoving the performance of nia, and there has been a request to include this tactic (which is useful on its own) without bundling it into `zify`. So that is what we do here. I leave the definition of it in `PreOmega` in case we want to eventually include it in `zify`/`nia`.
2019-01-24Don't pose any disjunctions in div_mod_to_quot_remJason Gross
Disjunctions seem to have a negative performance impact, so let's try implications instead.
2019-01-24Add Z.div_mod_to_quot_rem tactic, put it in zifyJason Gross
The various (micr)omega tactics now support `Z.div` and `Z.modulo`. I briefly looked into supporting `Nat.div` and `Nat.modulo`, but the conversions between `Z.div` and `Nat.div` are defined in `ZArith.Zdiv`, which depends on `Omega`, which depends on `PreOmega`, which is where `zify` is defined.

2018-10-18[universes] deprecate constr_of_globalMatthieu Sozeau
In favor of a constr_of_monomorphic_global function. When people move to the new Coqlib interface they will also see this deprecation message encouraging them to think about the best move. This commit changes a few references to constr_of_global and replaces them with a constr_of_monomorphic_global which makes it apparent that this is not the function to call to globalize polymorphic references. The remaining parts using constr_of_monomorphic_global are easily identifiable using this: omega, btauto, ring, funind and auto_ind_decl mainly (this fixes firstorder). What this means is that the symbols registered for these tactics have to be monomorphic for now.

2018-10-15Correct some spelling errorsBenjamin Barenblat
Lintian found some spelling errors in the Debian packaging for coq. Fix them most places they appear in the current source. (Don't change documentation anchor names, as that would invalidate external deeplinks.) This also fixes a bug in coqdoc: prior to this commit, coqdoc would highlight `instanciate` but not `instantiate`.
2018-10-10[coqlib] Rebindable Coqlib namespace.Emilio Jesus Gallego Arias
We refactor the `Coqlib` API to locate objects over a namespace `module.object.property`. This introduces the vernacular command `Register g as n` to expose the Coq constant `g` under the name `n` (through the `register_ref` function). The constant can then be dynamically located using the `lib_ref` function.

2018-10-05[kernel] Remove section paths from `KerName.t`Maxime Dénès
We remove sections paths from kernel names. This is a cleanup as most of the times this information was unused. This implies a change in the Kernel API and small user visible changes with regards to tactic qualification. In particular, the removal of "global discharge" implies a large cleanup of code. Additionally, the change implies that some machinery in `library` and `safe_typing` must now take an `~in_section` parameter, as to provide the information whether a section is open or not.
2018-09-24[engine] Remove and deprecate `nf_enter` et al.Emilio Jesus Gallego Arias

2018-09-05[build] Preliminary support for building Coq with `dune`.Emilio Jesus Gallego Arias
[Dune](https://github.com/ocaml/dune) is a compositional declarative build system for OCaml. It provides automatic generation of `version.ml`, `.merlin`, `META`, `opam`, API documentation; install management; easy integration with external libraries, test runners, and modular builds. In particular, Dune uniformly handles components regardless whether they live in, or out-of-tree. This greatly simplifies cases where a plugin [or CoqIde] is checked out in the current working copy but then distributed separately [and vice-versa]. Dune can thus be used as a more flexible `coq_makefile` replacement. For now we provide experimental support for a Dune build. In order to build Coq + the standard library with Dune type: ``` $ make -f Makefile.dune world ``` This PR includes a preliminary, developer-only preview of Dune for Coq. There is still ongoing work, see https://github.com/coq/coq/issues/8052 for tracking status towards full support. ## Technical description. Dune works out of the box with Coq, once we have fixed some modularity issues. The main remaining challenge was to support `.vo` files. As Dune doesn't support custom build rules yet, to properly build `.vo` files we provide a small helper script `tools/coq_dune.ml`. The script will scan the Coq library directories and generate the corresponding rules for `.v -> .vo` and `.ml4 -> .ml` builds. The script uses `coqdep` as to correctly output the dependencies of `.v` files. `coq_dune` is akin to `coq_makefile` and should be able to be used to build Coq projects in the future. Due to this pitfall, the build process has to proceed in three stages: 1) build `coqdep` and `coq_dune`; 2) generate `dune` files for `theories` and `plugins`; 3) perform a regular build with all targets are in scope. ## FAQ ### Why Dune? Coq has a moderately complex build system and it is not a secret that many developer-hours have been spent fighting with `make`. In particular, the current `make`-based system does offer poor support to verify that the current build rules and variables are coherent, and requires significant manual, error-prone. Many variables must be passed by hand, duplicated, etc... Additionally, our make system offers poor integration with now standard OCaml ecosystem tools such as `opam`, `ocamlfind` or `odoc`. Another critical point is build compositionality. Coq is rich in 3rd party contributions, and a big shortcoming of the current make system is that it cannot be used to build these projects; requiring us to maintain a custom tool, `coq_makefile`, with the corresponding cost. In the past, there has been some efforts to migrate Coq to more specialized build systems, however these stalled due to a variety of reasons. Dune, is a declarative, OCaml-specific build tool that is on the path to become the standard build system for the OCaml ecosystem. Dune seems to be a good fit for Coq well: it is well-supported, fast, compositional, and designed for large projects. ### Does Dune replace the make-based build system? The current, make-based build system is unmodified by this PR and kept as the default option. However, Dune has the potential ### Is this PR complete? What does it provide? This PR is ready for developer preview and feedback. The build system is functional, however, more work is necessary in order to make Dune the default for Coq. The main TODOs are tracked at https://github.com/coq/coq/issues/8052 This PR allows developers to use most of the features of Dune today: - Modular organization of the codebase; each component is built only against declared dependencies so components are checked for containment more strictly. - Hygienic builds; Dune places all artifacts under `_build`. - Automatic generation of `.install` files, simplified OPAM workflow. - `utop` support, `-opaque` in developer mode, etc... - `ml4` files are handled using `coqp5`, a native-code customized camlp5 executable which brings much faster `ml4 -> ml` processing. ### What dependencies does Dune require? Dune doesn't depend on any 3rd party package other than the OCaml compiler. ### Some Benchs: ``` $ /usr/bin/time make DUNEOPT="-j 1000" -f Makefile.dune states 59.50user 18.81system 0:29.83elapsed 262%CPU (0avgtext+0avgdata 302996maxresident)k 0inputs+646632outputs (0major+4893811minor)pagefaults 0swaps $ /usr/bin/time sh -c "./configure -local -native-compiler no && make -j states" 88.21user 23.65system 0:32.96elapsed 339%CPU (0avgtext+0avgdata 304992maxresident)k 0inputs+1051680outputs (0major+5300680minor)pagefaults 0swaps ```

2018-05-30[api] Remove deprecated object from `Term`Emilio Jesus Gallego Arias
We remove most of what was deprecated in `Term`. Now, `intf` and `kernel` are almost deprecation-free, tho I am not very convinced about the whole `Term -> Constr` renaming but I'm afraid there is no way back. Inconsistencies with the constructor policy (see #6440) remain along the code-base and I'm afraid I don't see a plan to reconcile them. The `Sorts` deprecation is hard to finalize, opening `Sorts` is not a good idea as someone added a `List` module inside it.

2017-11-23Using is_conv rather than eq_constr to find `nat` or `Z` in omega.Hugo Herbelin
Moving at the same to a passing "env sigma" style rather than passing "gl". Not that it is strictly necessary, but since we had to move functions taking only a "sigma" to functions taking also a "env", we eventually adopted the "env sigma" style. (The "gl" style would have been as good.) This answers wish #4717.
2017-10-05Omega now aware of context variables with bodies (in type Z or nat) (fix bug ↵Pierre Letouzey
148) For compatibility, this extra feature of omega could be disabled via Unset Omega UseLocalDefs. Caveat : for now, real let-ins inside goals or hyps aren't handled, use some "cbv zeta" reduction if you want to get rid of them. And context definitions whose types aren't Z or nat are ignored, some manual "unfold" are still mandatory if expanding these definitions will help omega.

2017-06-12zify: force reduction of (Z.max 0 0) and similar (fix #5439)Pierre Letouzey
Turn some "simpl" into "compute". Also do the same for the few "simpl (Z.of_nat ...)". This way, definition like Z.max are properly reduced, and moreover zify isn't sensible anymore to the "Arguments Z.of_nat : simpl never" that some user want (see also #5039). Unfortunately, the compute we're using now still honor the "Opaque" declarations, so a "Opaque Z.max" will block things again (see also #5374).

2017-06-06Remove the Sigma (monotonous state) API.Maxime Dénès
Reminder of (some of) the reasons for removal: - Despite the claim in sigma.mli, it does *not* prevent evar leaks, something like: fun env evd -> let (evd',ev) = new_evar env evd in (evd,ev) will typecheck even with Sigma-like type annotations (with a proof of reflexivity) - The API stayed embryonic. 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.
