2011-04-15Extraction: nicer error when a toplevel module has no body (#2525)letouzey
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

2011-04-13Extraction: opaque terms are not traversed anymore by defaultletouzey
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

2011-04-12Subtyping: align coqtop behavior concerning opaque csts on coqchk's oneletouzey
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
