* Lazyconstr -> OpaqueproofGravatar Enrico Tassi2014-02-26
| | | | | Make this module deal only with opaque proofs. Make discharging/substitution invariant more explicit via a third constructor.
* Declarations.mli: reorganization of modular structuresGravatar letouzey2013-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The earlier type [struct_expr_body] was far too broad, leading to code with unclear invariants, many "assert false", etc etc. Its replacement [module_alg_expr] has only three constructors: * MEident * MEapply : note the module_path as 2nd arg, no more constraints here * MEwith : no more constant_body inside, constr is just fine But no more SEBfunctor or SEBstruct constructor here (see below). This way, this datatype corresponds to algebraic expressions, i.e. anything that can appear in non-interactive modules. In fact, it even coincides now with [Entries.module_struct_entry]. - Functor constructors are now necessarily on top of other structures thanks to a generic [functorize] datatype. - Structures are now separated from algebraic expressions by design : the [mod_type] and [typ_expr] fields now only contain structures (or functorized structures), while [mod_type_alg] and [typ_expr_alg] are restricted to algebraic expressions only. - Only the implementation field [mod_expr] could be either algebraic or structural. We handle this via a specialized datatype [module_implementation] with four constructors: * Abstract : no implementation (cf. for instance Declare Module) * Algebraic(_) : for non-interactive modules, e.g. Module M := N. * Struct(_) : for interactive module, e.g. Module M : T. ... End M. * FullStruct : for interactive module with no type restriction. The [FullStruct] is a particular case of [Struct] where the implementation need not be stored at all, since it is exactly equal to its expanded type present in [mod_type]. This is less fragile than hoping as earlier that pointer equality between [mod_type] and [mod_expr] will be preserved... - We clearly emphasize that only [mod_type] and [typ_expr] are relevant for the kernel, while [mod_type_alg] and [typ_expr_alg] are there only for a nicer extraction and shorter module printing. [mod_expr] is also not accessed by the kernel, but it is important for Print Assumptions later. - A few implicit invariants remain, for instance "no MEwith in mod_expr", see the final comment in Declarations - Heavy refactoring of module-related files : modops, mod_typing, safe_typing, declaremods, extraction/extract_env.ml ... - Coqchk has been adapted accordingly. The code concerning MEwith in Mod_checking is now gone, since we cannot have any in mod_expr. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16712 85f007b7-540e-0410-9357-904b9bb8a0f7
* Robust display of NotConvertibleTypeField errors (fix #3008, #2995)Gravatar letouzey2013-03-21
| | | | | | | | | | | | | | Since the nametab isn't aware of everything needed to print mismatched types (cf the bug test-cases), we create a robust term printer that known how to print a fully-qualified name when [shortest_qualid_of_global] has failed. These Printer.safe_pr_constr and alii are meant to never fail (at worse they display "??", for instance when the env isn't rich enough). Moreover, the environnement may have changed between the raise of NotConvertibleTypeField and its display, so we store the original env in the exception. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16342 85f007b7-540e-0410-9357-904b9bb8a0f7

* Monomorphized a lot of equalities over OCaml integers, thanks toGravatar ppedrot2012-11-08
| | | | | | | | | | | | | | | | | the new Int module. Only the most obvious were removed, so there are a lot more in the wild. This may sound heavyweight, but it has two advantages: 1. Monomorphization is explicit, hence we do not miss particular optimizations of equality when doing it carelessly with the generic equality. 2. When we have removed all the generic equalities on integers, we will be able to write something like "let (=) = ()" to retrieve all its other uses (mostly faulty) spread throughout the code, statically. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15957 85f007b7-540e-0410-9357-904b9bb8a0f7

Techically, we simply allow the same label to occur at most twice in a structure_body, which is a (label * structure_field_body) list). These two label occurences should not be at the same level of fields (e.g. a SFBmodule and a SFBmind are ok, but not two SFBmodule's or a SFBmodule and a SFBmodtype).

* Subtyping: align coqtop behavior concerning opaque csts on coqchk's oneGravatar letouzey2011-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After discussion with Bruno and Hugo, coqtop now accepts that an opaque constant in a module type could be implemented by anything of the right type, even if bodies differ. Said otherwise, with respect to subtyping, an opaque constant behaves just as a parameter. This was already the case in coqchk, and a footnote in documentation is advertising for quite some time that: "Opaque definitions are processed as assumptions." Truly, it might seem awkward that "Definition x:=3" can implement "Lemma x:nat. Proof 2. Qed." but the opacity ensures that nothing can go wrong afterwards, since Coq is forced to ignore that the x in signature has body "2". Similarly, "T with Definition x := c" is now legal when T contains an opaque x, even when this x isn't convertible with c. By avoiding accesses to opaque bodies, we also achieve some speedup (less delayed load of .vo final sections containing opaque terms). Nota: the extraction will have to be adapted, since for the moment it might access the body of opaque constants: the warning emitted when doing that should become an error. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13987 85f007b7-540e-0410-9357-904b9bb8a0f7
* 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

* This big commit addresses two problems:Gravatar soubiran2009-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1- Management of the name-space in a modular development / sharing of non-logical objects. 2- Performance of atomic module operations (adding a module to the environment, subtyping ...). 1- There are 3 module constructions which derive equalities on fields from a module to another: Let P be a module path and foo a field of P Module M := P. Module M. Include P. ... End M. Declare Module K : S with Module M := P. In this 3 cases we don't want to be bothered by the duplication of names. Of course, M.foo delta reduce to P.foo but many non-logical features of coq do not work modulo conversion (they use eq_constr or constr_pat object). To engender a transparent name-space (ie using P.foo or M.foo is the same thing) we quotient the name-space by the equivalence relation on names induced by the 3 constructions above. To implement this, the types constant and mutual_inductive are now couples of kernel_names. The first projection correspond to the name used by the user and the second projection to the canonical name, for example the internal name of M.foo is (M.foo,P.foo). So: ************************************************************************************* * Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values * ************************************************************************************* Map and Set indexed on names are ordered on user name for the kernel side and on canonical name outside. Thus we have sharing of notation, hints... for free (also for a posteriori declaration of them, ex: a notation on M.foo will be avaible on P.foo). If you want to use this, use the appropriate compare function defined in name.ml or libnames.ml. 2- No more time explosion (i hoppe) when using modules i have re-implemented atomic module operations so that they are all linear in the size of the module. We also have no more unique identifier (internal module names) for modules, it is now based on a section_path like mechanism => we have less substitutions to perform at require, module closing and subtyping but we pre-compute more information hence if we instanciate several functors then we have bigger vo. Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions above, i will work on it soon... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12406 85f007b7-540e-0410-9357-904b9bb8a0f7

Pour éviter le côté contre-intuitif d'avoir unit dans Type et Prop <= Set, on garde la représentation de Prop au sein de la hiérarchie prédicative sous la forme "Type (max ([],[])" (le niveau sans aucune contrainte inférieure, appelons Type -1) et on adapte les fonctions de sous-typage et de typage pour qu'elle prenne en compte la règle Type -1 <= Prop (cf reduction.ml, reductionops.ml, et effets incidents dans Termops.refresh_universes et Univ.super).
