* Added backtrace primitives.Gravatar ppedrot2013-01-28
| | | | | | | | | | | | | | | | | | | | | | Using OCaml 3.11+ builtin facilities to record stack frames during exception raising, we can now recover at runtime the backtrace of an uncaught toplevel exception and display it to the user, without the infamous OCaml debugger. The backtrace is displayed when using the [-debug] flag. This requires a bit of discipline, as each time we reraise an exception we need to keep track of those frames we discarded between the previous raise and the current [try-with] branch. Currently, only [Anomaly] is handled, but this can be ported to any exception as long as we add the backtrace info into the exception, and we provide the corresponding handler to [Backtracke.register_backtrace_handler]. Hopefully this should not be to costly, as we only do little work when reraising, and only with the [-debug] flag set. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16166 85f007b7-540e-0410-9357-904b9bb8a0f7

* Checker/subtyping.ml: avoid adding in env a module already there (fix #2609)Gravatar letouzey2011-10-26
| | | | | | | | | | | | | | | | | | | When doing a [check_subtypes env mtb1 mtb2], we used to always add [mtb1] in the environment. But since the stricter checks of commit r14150, this is an error if the environment already knows [mtb1] (for instance when doing (F M) and checking that M is compatible with the type of the arg of F. [check_subtypes] now expect [mtb1] to be already in env, and we move the add_module to the unique call site of this function that requires it. Moreover, we solve a second issue : when subtyping a functor, we update the environment once inside the functor, and this is also refused by the checks of commits r14150. So we first remove the module name from the env before doing the update. Since the module added earlier was a functor, there is no inner defs to chase in env. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14615 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
