* Lazy loading of opaque proofs: fast as -dont-load-proofs without its drawbacksGravatar letouzey2011-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent experiment with -dont-load-proofs in the stdlib showed that this options isn't fully safe: some axioms were generated (Include ? functor application ? This is still to be fully understood). Instead, I've implemented an idea of Yann: only load opaque proofs when we need them. This is almost as fast as -dont-load-proofs (on the stdlib, we're now 15% faster than before instead of 20% faster with -dont-load-proofs), but fully compatible with Coq standard behavior. Technically, the const_body field of Declarations.constant_body now regroup const_body + const_opaque + const_inline in a ternary type. It is now either: - Undef : an axiom or parameter, with an inline info - Def : a transparent definition, with a constr_substituted - OpaqueDef : an opaque definition, with a lazy constr_substitued Accessing the lazy constr of an OpaqueDef might trigger the read on disk of the final section of a .vo, where opaque proofs are located. Some functions (body_of_constant, is_opaque, constant_has_body) emulate the behavior of the old fields. The rest of Coq (including the checker) has been adapted accordingly, either via direct access to the new const_body or via these new functions. Many places look nicer now (ok, subjective notion). There are now three options: -lazy-load-proofs (default), -force-load-proofs (earlier semantics), -dont-load-proofs. Note that -outputstate now implies -force-load-proofs (otherwise the marshaling fails on some delayed lazy). On the way, I fixed what looked like a bug : a module type (T with Definition x := c) was accepted even when x in T was opaque. I also tried to clarify Subtyping.check_constant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13952 85f007b7-540e-0410-9357-904b9bb8a0f7

* Remove the "Boxed" syntaxes and the const_entry_boxed fieldGravatar letouzey2011-01-28
| | | | | | | | | | | | | | | | According to B. Gregoire, this stuff is obsolete. Fine control on when to launch the VM in conversion problems is now provided by VMcast. We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint. The option "(Un)Set Boxed Definitions" aren't there anymore, but tolerated (as no-ops), since unknown options raise a warning instead of an error by default. Some more cleaning could be done in the vm. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13806 85f007b7-540e-0410-9357-904b9bb8a0f7

* Change of nomenclature: rawconstr -> glob_constrGravatar glondu2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a discrepancy of the notions "raw" and "globalized" between constrs and tactics, and some confusion of the notions in e.g. genarg.mli (see all globwit_* there). This commit is a first step towards unification of terminology between constrs and tactics. Changes in module names will be done separately. In extraargs.ml4, the "ARGUMENT EXTEND raw" and related stuff, even affected by this change, has not been touched and highlights another confusion in "ARGUMENT EXTEND" in general that will be addressed later. The funind plugin doesn't respect the same naming conventions as the rest, so leave some "raw" there for now... they will be addressed later. This big commit has been generated with the following command (wrapped here, but should be on a *single* line): perl -pi -e 's/(\W(?:|pp|pr_l)|_)raw((?:constrs?|type|vars|_binder| _context|decl|_decompose|_compose|_make)(?:\W|_))/\1glob_\2/g;s/glo b__/glob_/g;s/prraw/prglob/g;s/(\W)R((?:Ref|Var|Evar|PatVar|App|Lam bda|Prod|LetIn|Cases|LetTuple|If|Rec|Sort|Hole|Cast|Dynamic)\W)/\1G \2/g' `git ls-files|grep -v dev/doc/changes.txt` git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13743 85f007b7-540e-0410-9357-904b9bb8a0f7

* Here comes the commit, announced long ago, of the new tactic engine.Gravatar aspiwack2010-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fairly large commit (around 140 files and 7000 lines of code impacted), it will cause some troubles for sure (I've listed the know regressions below, there is bound to be more). At this state of developpement it brings few features to the user, as the old tactics were ported with no change. Changes are on the side of the developer mostly. Here comes a list of the major changes. I will stay brief, but the code is hopefully well documented so that it is reasonably easy to infer the details from it. Feature developer-side: * Primitives for a "real" refine tactic (generating a goal for each evar). * Abstract type of tactics, goals and proofs * Tactics can act on several goals (formally all the focused goals). An interesting consequence of this is that the tactical (. ; [ . | ... ]) can be separated in two tacticals (. ; .) and ( [ . | ... ] ) (although there is a conflict for this particular syntax). We can also imagine a tactic to reorder the goals. * Possibility for a tactic to pass a value to following tactics (a typical example is an intro function which tells the following tactics which name it introduced). * backtracking primitives for tactics (it is now possible to implement a tactical '+' with (a+b);c equivalent to (a;c+b;c) (itself equivalent to (a;c||b;c)). This is a valuable tool to implement tactics like "auto" without nowing of the implementation of tactics. * A notion of proof modes, which allows to dynamically change the parser for tactics. It is controlled at user level with the keywords Set Default Proof Mode (this is the proof mode which is loaded at the start of each proof) and Proof Mode (switches the proof mode of the current proof) to control them. * A new primitive Evd.fold_undefined which operates like an Evd.fold, except it only goes through the evars whose body is Evar_empty. This is a common operation throughout the code, some of the fold-and-test-if-empty occurences have been replaced by fold_undefined. For now, it is only implemented as a fold-and-test, but we expect to have some optimisations coming some day, as there can be a lot of evars in an evar_map with this new implementation (I've observed a couple of thousands), whereas there are rarely more than a dozen undefined ones. Folding being a linear operation, this might result in a significant speed-up. * The declarative mode has been moved into the plugins. This is made possible by the proof mode feature. I tried to document it so that it can serve as a tutorial for a tactic mode plugin. Features user-side: * Unfocus does not go back to the root of the proof if several Focus-s have been performed. It only goes back to the point where it was last focused. * experimental (non-documented) support of keywords BeginSubproof/EndSubproof: BeginSubproof focuses on first goal, one can unfocus only with EndSubproof, and only if the proof is completed for that goal. * experimental (non-documented) support for bullets ('+', '-' and '*') they act as hierarchical BeginSubproof/EndSubproof: First time one uses '+' (for instance) it focuses on first goal, when the subproof is completed, one can use '+' again which unfocuses and focuses on next first goal. Meanwhile, one cas use '*' (for instance) to focus more deeply. Known regressions: * The xml plugin had some functions related to proof trees. As the structure of proof changed significantly, they do not work anymore. * I do not know how to implement info or show script in this new engine. Actually I don't even know what they were suppose to actually mean in earlier versions either. I wager they would require some calm thinking before going back to work. * Declarative mode not entirely working (in particular proofs by induction need to be restored). * A bug in the inversion tactic (observed in some contributions) * A bug in Program (observed in some contributions) * Minor change in the 'old' type of tactics causing some contributions to fail. * Compilation time takes about 10-15% longer for unknown reasons (I suspect it might be linked to the fact that I don't perform any reduction at QED-s, and also to some linear operations on evar_map-s (see Evd.fold_undefined above)). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12961 85f007b7-540e-0410-9357-904b9bb8a0f7

Lescuyer, specification of compare is now inductive - GenericMinMax: axiomatisation + properties of min and max out of OrderedTypeFull structures. - MinMax.v, {Z,P,N,Q}minmax.v are specialization of GenericMinMax, with also some domain-specific results, and compatibility layer with already existing results. - Some ML code of plugins had to be adapted, otherwise wrong "eq", "lt" or simimlar constants were found by functions like coq_constant. - Beware of the aliasing problems: for instance eq:=@eq t instead of eq:=@eq M.t in Make_UDT made (r)omega stopped working (Z_as_OT.t instead of Z in statement of Zmax_spec). - Some Morphism declaration are now ambiguous: switch to new syntax anyway. - Misc adaptations of FSets/MSets - Classes/RelationPairs.v: from two relations over A and B, we inspect relations over A*B and their properties in terms of classes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12461 85f007b7-540e-0410-9357-904b9bb8a0f7
