* Delayed the computation of parameters in sort polymorphism ofGravatar herbelin2013-05-14
| | | | | | | | inductive types. This saves some computation, but also allows incidentally to retype terms with evars without failing if an inductive type as an argument whose type is an evar. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16526 85f007b7-540e-0410-9357-904b9bb8a0f7
* Splitting Term into five unrelated interfaces:Gravatar ppedrot2013-04-29
| | | | | | | | | | | | | | | | | 1. sorts.ml: A small file utility for sorts; 2. constr.ml: Really low-level terms, essentially kind_of_constr, smart constructor and basic operators; 3. vars.ml: Everything related to term variables, that is, occurences and substitution; 4. context.ml: Rel/Named context and all that; 5. term.ml: derived utility operations on terms; also includes constr.ml up to some renaming, and acts as a compatibility layer, to be deprecated. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16462 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

* Applicative commutative cuts in Fixpoint guard conditionGravatar pboutill2010-05-18
| | | | | | | | | | | | | | | | | | | | | In "(match ... with |... -> fun x -> t end) u", "x" has now the subterm property of "u" in the analysis of "t". Commutative cuts aren't compatible with typing so we need to ensure that term of "x"'s type and term of "u"'s have the same subterm_spec. Consequently,declaration.MRec argument has changed to the inductive name instead of only the number of the inductive in the mutual_inductive family. In subterm_specif and check_rec_call, arguments are stored in a stack. At each lambda, one element is popped to add in renv a smarter subterm_spec for the variable. subterm_spec of constructor's argument was added this way, the job is now done more often. Some eta contracted match branches are now accepted but enforcing eta-expansion of branches might be anyway a recommended invariant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13012 85f007b7-540e-0410-9357-904b9bb8a0f7

* Move from ocamlweb to ocamdoc to generate mli documentationGravatar pboutill2010-04-29
| | | | | | | | | | | | | | | | | | | dev/ocamlweb-doc has been erased. I hope no one still use the "new-parse" it generate. In dev/, make html will generate in dev/html/ "clickable version of mlis". (as the caml standard library) make coq.pdf will generate nearly the same awfull stuff that coq.ps was. make {kernel,lib,parsing,..}.{dot,png} will do the dependancy graph of the given directory. ocamldoc comment syntax is here : http://caml.inria.fr/pub/docs/manual-ocaml/manual029.html The possibility to put graphs in pdf/html seems to be lost. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12969 85f007b7-540e-0410-9357-904b9bb8a0f7
