* Added multiple implicit arguments rules per name.Gravatar herbelin2010-10-03
| | | | | | | | | Example: "Implicit Arguments eq_refl [[A] [x]] [[A]]". This should a priori be used with care (it might be a bit disturbing seeing the same constant used with apparently incompatible signatures). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13484 85f007b7-540e-0410-9357-904b9bb8a0f7
* Simplify tactic(_)-bound arguments in TACTIC EXTEND rulesGravatar glondu2010-09-30
| | | | | | | | | | | | | | Arguments bound with tactic(_) in TACTIC EXTEND rules are now of type glob_tactic_expr, instead of glob_tactic_expr * tactic. Only the first component is kept, the second one can be obtained with Tacinterp.eval_tactic. Rationale: these declare parsing rules, and eval_tactic is a semantic action, and therefore should be done in the rule body instead. Moreover, having the glob_tactic_expr and its evaluation captured by these rules was quite confusing IMHO. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13480 85f007b7-540e-0410-9357-904b9bb8a0f7

* Remove some occurrences of "open Termops"Gravatar glondu2010-09-28
| | | | | | | Functions from Termops were sometimes fully qualified, sometimes not in the same module. This commit makes their usage more uniform. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13470 85f007b7-540e-0410-9357-904b9bb8a0f7
* Remove "init" label from Termops.it_mk* specialized functionsGravatar glondu2010-09-28
| | | | | | | | | | These functions are applied much more often without labels than with them (the alternate of adding the label wherever relevant changes 124 lines instead of 41). Moreover, this is more consistent with the Term module and there is no ambiguity in argument types.

But it seems quite unlikely to encounter both situations (clever partial application and non-generalizable variable) at the same time. Compcert is ok, for instance.

* Extraction: multiple fixes related with the Not_found encountered by X. LeroyGravatar letouzey2010-09-17
| | | | | | | | | | | | | | | | | | | Cf. coqdev for the details of the bug report. - Protect some Hashtbl.find and other risky functions in order to avoid as much as possible to end with an irritating Anomaly : Not_found. - Re-enable in pp_ocaml_extern the case of a module-file used as a module (e.g. module A' := A for A.v) when doing modular extraction. - Rework the code that decides to "open" or not modules initially: opening A when A contains a submodule B hides the file B even when B isn't opened itself, we avoid that now. - Fix some tables (sets or maps) used by extraction for which it is critical to consider constants/inductives/global_reference _not_ modulo the equivalence of Elie, but rather via Pervasives.compare. Still to do : avoid appearance of '_a in extracted code. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13424 85f007b7-540e-0410-9357-904b9bb8a0f7

* Extraction: fix a bit the extraction under modulesGravatar letouzey2010-07-15
| | | | | | | | | | | | | | | | | | Extraction under modules is highly experimental, and just work a bit. Don't expect too much of it. With this commit, I simply avoid a few "assert false" to occur when we are under modules. But things are still quite wrong, for instance with: Definition foo. Module M. Definition bar := foo. Recursive Extraction bar. Extraction of bar is ok, but foo isn't displayed, since extraction can't get it: Lib.contents_after doesn't mention it, it is probably in some frozen summary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13281 85f007b7-540e-0410-9357-904b9bb8a0f7

* Extraction: restrict autoinling to csts whose body is globally visible (fix ↵Gravatar letouzey2010-07-08
| | | | | | | | | | | | | | | | #2241) Here, the constants "without body" we don't want to autoinline are constants made opaque by the rigid signature of their module. As mentionned by X.L. inlining them might lead to untypable code. The current solution is safe, but not ideal: we could want to inline such constants at least inside their own module, and we could also want to inline constants that are not globally visible (functors...). NB: AutoInline is anyway not activated by default anymore git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13273 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: more factorization of common match branchesGravatar letouzey2010-07-08
| | | | | | | | | | | | | | In addition to the "| _ -> cst" situation, now we can also reconstruct a "| e -> f e" final branch. For instance, this has a tremenduous effect on Compcert/backend/Selection.v. NB: The "fun" factorisation is almost more general than the "cst" situation, but not always. Think of A=>A|B=>A, 1st branch will be recognized as (fun x->x), not (fun x->A). We also add a fine detection of inductive types with phantom type variables, for which this optimisation is type-unsafe. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13267 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: Unset Extraction AutoInline is now the defaultGravatar letouzey2010-07-08
| | | | | | | | | | | The auto-inlining has always been cumbersome. We only keep the inlining of recursors (foo_rect for inductive foo), and a short list of specific constants declared in mlutil.ml. In particular we inline andb and orb to keep their lazy behavior. The previous behavior is available via Set Extraction AutoInline git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13266 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | And similarly for Haskell: we do not force capitalized/uncapitalized filenames anymore, but we rather follow the name of the .v file (with new extensions of course). Ok, this is an incompatible change, but it is really convenient, some people where actually already doing some hacks to have this behavior (cf. Compcert). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13260 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: get advantage of nicer, algebraic, module typesGravatar letouzey2010-07-07
| | | | | | | | | | | | We use the mod_type_alg and typ_expr_alg field when they aren't empty. As a consequences, many signatures are now simple abbreviations, or "with" constructions, leading to .mli that are _way_ shorter this way. Various fixups concerning the "with Definition" syntax. In extract_seb_spec, we propagate both the alg and non-alg versions of the structure, for handlying nicely the "with" situation, and expanding situations not possible in ocaml. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13249 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: some more work on the (re)naming frameworkGravatar letouzey2010-07-07
| | | | | | | | | | | | | - MPbound can be part of visible_mps (when printing the type of a module parameter, or when printing body of a With), hence the locality test base_mp mp = base_mp (top_visible_mp ()) isn't accurate. - new organisation, pp_ocaml_gen is splitted in many sub-functions, attempt to be clearer - the shortcut (if List.length ls = 1 then ...) isn't safe, we might detect name conflict even in this case. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13248 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: (yet another) rework of the renaming codeGravatar letouzey2010-07-05
| | | | | | | | | | | | | | | - Add module parameters in the structure of visible_layer, in order for module params to be part of name clash detection, avoiding this way a source of potentially wrong code. - In case of clash, module params are alpha-renamed to something unique (Foo__XXX where XXX is the number contained in the mbid). This solves some situations that were unsupported by extraction. for instance the "Module F (X:T). Module X:=X. ... End F." - We now check in Coq identifiers the presence of the extraction-reserved string __. If it is found, we issue a warning (which might become an error someday). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13240 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: better support of modulesGravatar letouzey2010-07-02
| | | | | | | | | | | | | - For Haskell, modules abbreviations and applied functors are expanded. The only remaining sitation that isn't supported is extracting functors and applying them after extraction. - Add a module extraction for Scheme with the same capabilities as for Haskell (with no Extraction Library, though). - Nicer extracted module types (use of the mb.mod_type_alg if present) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13236 85f007b7-540e-0410-9357-904b9bb8a0f7
