* More monomorphic List.mem + List.assoc + ...Gravatar letouzey2013-10-24
| | | | | | | | | | | To reduce the amount of syntactic noise, we now provide a few inner modules Int.List, Id.List, String.List, Sorts.List which contain some monomorphic (or semi-monomorphic) functions such as mem, assoc, ... NB: for Int.List.mem and co we reuse List.memq and so on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16936 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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
* State Transaction MachineGravatar gareuselesinge2013-08-08
| | | | | | | | | | | | | | | | | | | | | The process_transaction function adds a new edge to the Dag without executing the transaction (when possible). The observe id function runs the transactions necessary to reach to the state id. Transaction being on a merged branch are not executed but stored into a future. The finish function calls observe on the tip of the current branch. Imperative modifications to the environment made by some tactics are now explicitly declared by the tactic and modeled as let-in/beta-redexes at the root of the proof term. An example is the abstract tactic. This is the work described in the Coq Workshop 2012 paper.

* Fix extraction of inductive types that Coq auto-detects to be in PropGravatar letouzey2013-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | Typical example : Inductive t := T : t -> t. Earlier, the extraction was using a shortcut to get the sort of t (via some mind_arity stuff), but this was producing a less precise answer (here InType) than a full Retyping.get_sort_family_of (here InProp since t is a singleton type, with no content). The extraction of t was hence awkward, since the type of the constructor T was computed with the precise method, and its argument was optimized out. Now the whole t is considered logical by the extraction. NB: to avoid this clever but highly non-intuitive behavior of Coq placing the above t in Prop, for the moment you have to fix its sort, for instance: Inductive t : Set := T : t -> t. Using Type instead of Set still activates Coq's minimal sort detection... Instead, you could also use one specific TypeX obtained via Definition TypeX := Type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16203 85f007b7-540e-0410-9357-904b9bb8a0f7

* The new ocaml compiler (4.00) has a lot of very cool warnings,Gravatar regisgia2012-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility.

Earlier "full" pattern correspond to pattern Pusual. Patterns Pwild and Prel allow to encode optimized matchs without hacks as earlier. Other pattern situations aren't used (yet) by extraction, but only by P.N Tollitte's code. A MLtuple constructor has been introduced. It isn't used by the extraction for the moment, but only but P.N.

* Extraction Implicit: fix the numbering of constructor argumentsGravatar letouzey2011-09-05
| | | | | | | | | | | | | | | | | | | | For constructors, the numbers of parameters used to be wrongly ignored. Consider for instance : Inductive listn (A:Type) : nat -> Type := | niln : listn A 0 | consn : forall n, A -> listn A n -> listn A (S n). Saying "Extraction Implicit consn [n]" should now work correctly, and correspond to the alternative syntax "Extraction Implicit consn [2]", where 2 is the position of the argument n when counting with inductive parameters. Note that saying "Extraction Implicit consn [1]" (or [A]) is now a no-op : constructors have always been cleaned-up from their parameters during extraction. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14449 85f007b7-540e-0410-9357-904b9bb8a0f7

* Set Extraction KeepSingleton: an option for not decapsulating singleton typesGravatar letouzey2011-07-04
| | | | | | | | | | | | A informative inductive type with one constructor C and one informative arg to C is normally extracted as an identity, with C removed, see for example the "sig" type. When this new option is set, these singleton types are left untouch, providing extracted code which is closer to the initial Coq development. Feature requested by Wouter Swiestra. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14260 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: forbid Prop-polymorphism of inductives when extracting to OcamlGravatar letouzey2011-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A particular case in sort-polymorphism of inductive types allows an informative type (such as prod) to have instances in Prop: (I,I) : True * True : Prop This is due to the fact that prod is a singleton type: indeed (I,I) has no informative content. But this invalidates an important invariant for the correctness of the extraction: inductive constructors stop having always the same sort as their inductive type. Consider for instance: Definition f (X:Type)(x:X*X)(g:X->nat) := g (fst x). Definition test := f _ (I,I) (fun _ => 0). Then the inductive element (I,I) is extracted as a logical part __, but during a strict evaluation (i.e. in Ocaml, not Haskell), this __ will be given to fst, and hence to a match, leading to a nasty result (potentially segfault). Haskell is not affected, since fst is never evaluated. This patch adds a check for this situation during any Ocaml extraction, leading for the moment to a fatal error. Some functions in inductive.ml and retyping.ml now have an extra optional argument ?(polyprop=true) that should stay untouched in regular Coq usage, while type-checking done during extraction will disable this prop-polymorphism. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14256 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

* Extraction: an experimental command to get rid of some cst/constructor argumentsGravatar letouzey2010-04-30
| | | | | | | | | | | | The command : Extraction Implicit foo [1 3]. will tell the extraction to consider fst and third arg of foo as implicit, and remove them, unless a final occur-check after extraction shows they are still there. Here, foo can be a inductive constructor or a global constant. This allow typicaly to extract vectors into usual list :-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12982 85f007b7-540e-0410-9357-904b9bb8a0f7
* Remove the svn-specific $Id$ annotationsGravatar letouzey2010-04-29
| | | | | | | | | | | - Many of them were broken, some of them after Pierre B's rework of mli for ocamldoc, but not only (many bad annotation, many files with no svn property about Id, etc) - Useless for those of us that work with git-svn (and a fortiori in a forthcoming git-only setting) - Even in svn, they seem to be of little interest git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: less eta in calls to global functions, better optimization phaseGravatar letouzey2010-04-16
| | | | | | | | | | | | - we saturate the normalize function : as long as (kill_dummy + simpl) isn't a nop, we do it again. - generalize_case allowed on all types of theories/Init/*.v instead of only bool,sumbool,sumor. NB: this optim cannot be performed on any type, it might produce untyped code. - common_branch allowed on match with one branch: in this situation it indicates whether the match can be removed or not. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12942 85f007b7-540e-0410-9357-904b9bb8a0f7
