* Coqc: fix the exit codeGravatar letouzey2011-04-15
| | | | | | Patch suggested by Benjamin Monate git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14016 85f007b7-540e-0410-9357-904b9bb8a0f7
* Extraction: nicer error when a toplevel module has no body (#2525)Gravatar letouzey2011-04-15
| | | | | | | | | I thought this situation wasn't possible, hence the Option.get. But it's apparently legal to use Declare Module anywhere, even outside a Module Type. No idea on how to handle that at extraction for the moment, hence a proper "unsupported" error message. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14013 85f007b7-540e-0410-9357-904b9bb8a0f7

* Extraction: opaque terms are not traversed anymore by defaultGravatar letouzey2011-04-13
| | | | | | | | | | | | | In signatures, opaque terms are always seen as parameters. In implementations, a flag Set/Unset Extraction AccessOpaque allows to customize things: - Set : opacity is ignored (this is the old behavior) - Unset : opaque terms are extracted as axioms (default now) Some warnings are anyway emitted when extraction encounters informative opaque terms. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13999 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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
