2011-12-17Added a flag to control the use of typing when instantiating appliedherbelin
meta in the tactic unification algorithm ("auto" becomes much slower if it takes into account the type of metas). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14813 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-12-16Introducing a notion of evar candidates to be used when an evar isherbelin
known in advance to be instantiable by only a finite number of terms. When an evar with candidates remain unsolved after unification, the first candidate is taken as a heuristic. This is used in particular to reduce the number of pending conversion problems when trying to infer the return clause of a pattern-matching problem. As an example, this repairs test 2615.v. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14797 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-12-12Proof using ...gareuselesinge
New vernacular "Proof using idlist" to declare the variables to be discharged at the end of the current proof.

2011-11-17Merge subinstances branch by me and Tom Prince.msozeau
This adds two experimental features to the typeclass implementation: - Path cuts: a way to specify through regular expressions on instance names search pathes that should be avoided (e.g. [proper_flip proper_flip]). Regular expression matching is implemented through naïve derivatives. - Forward hints for subclasses: e.g. [Equivalence -> Reflexive] is no longer applied backwards, but introducing a specific [Equivalence] in the environment register a [Reflexive] hint as well. Currently not backwards-compatible, the next patch will allow to specify direction of subclasses hints. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14671 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-11-04Auto: removal of ?use_core_db obsolete now that we have nocoreletouzey
Suggestion of Tom Prince, that told me that he has adapted the rippling tactic to use the "nocore" pseudo-database. Since this tactic was the only user of these optional arguments ?use_core_db, let's remove them. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14629 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-11-02Add type annotations around all calls to Libobject.declare_objectletouzey
These annotations are purely optional, but could be quite helpful when trying to understand the code, and in particular trying to trace which which data-structure may end in the libobject part of a vo. By the way, we performed some code simplifications : - in Library, a part of the REQUIRE objects was unused. - in Declaremods, we removed some checks that were marked as useless, this allows to slightly simplify the stored objects. To investigate someday : in recordops, the RECMETHODS is storing some evar_maps. This is ok for the moment, but might not be in the future (cf previous commit on auto hints). This RECMETHODS was not detected by my earlier tests : not used in the stdlib ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14627 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-10-26Auto: avoid storing clausenv (and hence env, evar_map, universes) in voletouzey
It appears that registration of hints is the only place (at least when compiling stdlib) where Univ.universes (the graph of universes) is stored in vo. More precisely, a Hint Resolve will place in vo a pri_auto_tactic, which may contain some clausenv, which contain both a env and a evar_map, each of them containing a Univ.universes In fact, even env and evar_map are also never stored in vo apart from hints registration. Currently, there's nothing wrong in this storing of env / evar_map / universes. In fact, it seems that every stored universes are actually empty. Same for env, thanks to awkward lines { cl with env=empty_env }. But this may hinder potential evolutions of Univ.universes toward a private per-session representation. Conclusion: it is cleaner (and not that hard) to store a Term.types instead of the clausenv in vo, and reconstitute the clausenv at Require-time. On a compilation of the stdlib, the time effect is hardly noticable (<1%). NB: a Univ.universes is also stored in initial.coq, but this is a different story (Write State ...) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14611 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-10-22Fixing Equality.injectable which did not detect an equality withoutherbelin
constructors as non relevant for injection. Also made injection failing in such situation. Incidentally, this fixes a loop in Invfun.reflexivity_with_destruct_cases (observed in the compilation of CoinductiveReals.LNP_Digit). The most probable explanation is that this loop was formerly protected by a failing rewrite which stopped failing after revision 14549 made second-order pattern-matching more powerful. Also suppressed dead code in Invfun.intros_with_rewrite. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14577 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-10-11Various simplifications about constant_of_delta and mind_of_deltaletouzey
Most of the time, a constant name is built from: - a kernel_name for its user part - a delta_resolver applied to this kernel_name for its canonical part With this patch we avoid building unnecessary constants for immediately amending them (cf in particular the awkward code removed in safe_typing). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14545 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-08-10Propagated information from the reduction tactics to the kernel soherbelin
that the kernel conversion solves the delta/delta critical pair the same way the tactics did. This allows to improve Qed time when slow down is due to conversion having (arbitrarily) made the wrong choice. Propagation is done thanks to a new kind of cast called REVERTcast. Notes: - Vm conversion not modified - size of vo generally grows because of additional casts - this remains a heuristic... for the record, when a reduction tactic is applied on the goal t leading to new goal t', this is translated in the kernel in a conversion t' <= t where, hence, reducing in t' must be preferred; what the propagation of reduction cast to the kernel does not do is whether it is preferable to first unfold c or to first compare u' and u in "c u' = c u"; in particular, intermediate casts are sometimes useful to solve this kind of issues (this is the case e.g. in Nijmegen/LinAlg/subspace_dim.v where the combination "simpl;red" needs the intermediate cast to ensure Qed answers quickly); henceforth the merge of nested casts in mkCast is deactivated - for tactic "change", REVERTcast should be used when conversion is in the hypotheses, but convert_hyp does not (yet) support this (would require e.g. that convert_hyp overwrite some given hyp id with a body-cleared let-binding new_id := Cast(old_id,REVERTCast,t)) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14407 85f007b7-540e-0410-9357-904b9bb8a0f7
