2016-10-24Fix #5127 Memory corruption with the VMMaxime Dénès
The bytecode interpreter ensures that the stack space available at some points is above a static threshold. However, arbitrary large stack space can be needed between two check points, leading to segmentation faults in some cases. We track the use of stack space at compilation time and add an instruction to ensure greater stack capacity when required. This is inspired from OCaml's PR#339 and PR#7168. Patch written with Benjamin Grégoire.
2016-07-03errors.ml renamed into cErrors.ml (avoid clash with an OCaml compiler-lib ↵Pierre Letouzey
module) For the moment, there is an Error module in compilers-lib/ocamlbytecomp.cm(x)a

2015-10-28Refine Gregory Malecha's patch on VM and universe polymorphism.Maxime Dénès
- Universes are now represented in the VM by a structured constant containing the global levels. This constant is applied to local level variables if any. - When reading back a universe, we perform the union of these levels and return a [Vsort]. - Fixed a bug: structured constants could contain local universe variables in constructor arguments, which has to be prevented. Was showing up for instance when evaluating [cons _ list (nil _)] with a polymorphic [list] type. - Fixed a bug: polymorphic inductive types can have an empty stack. Was showing up when evaluating [bool] with a polymorphic [bool] type. - Made a few cosmetic changes. Patch written with Benjamin Grégoire.
2015-10-28Adds support for the virtual machine to perform reduction of universe ↵Gregory Malecha
polymorphic definitions. - This implementation passes universes in separate arguments and does not eagerly instanitate polymorphic definitions. - This means that it pays no cost on monomorphic definitions.

2015-07-05Fix handling of primitive projections in VM.Maxime Dénès
I'm pushing this patch now because the previous treatment of such projections in the VM was already unsound. It should however be carefully reviewed.

2015-01-15Correct restriction of vm_compute when handling universe polymorphicMatthieu Sozeau
definitions. Instead of failing with an anomaly when trying to do conversion or computation with the vm's, consider polymorphic constants as being opaque and keep instances around. This way the code is still correct but (obviously) incomplete for polymorphic definitions and we avoid introducing an anomaly. The patch does nothing clever, it only keeps around instances with constants/inductives and compile constant bodies only for non-polymorphic definitions.

2012-11-08Monomorphized a lot of equalities over OCaml integers, thanks toppedrot
the new Int module. Only the most obvious were removed, so there are a lot more in the wild. This may sound heavyweight, but it has two advantages: 1. Monomorphization is explicit, hence we do not miss particular optimizations of equality when doing it carelessly with the generic equality. 2. When we have removed all the generic equalities on integers, we will be able to write something like "let (=) = ()" to retrieve all its other uses (mostly faulty) spread throughout the code, statically. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15957 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-10-02Remove some dead code in the vmletouzey
Apparently Cysmtable.set_global_boxed is unused, and removing it allows to get rid of a bunch of C code concerning "boxed" things (including ACCUMULATECOND instruction). Still TODO: Csymtable.set_transparent_const and Csymtable.set_opaque_const appear to be no-ops. Should we remove them ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15845 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-09-14This patch removes unused "open" (automatically generated fromregisgia

In particular, the unused lib/tlm.ml and lib/gset.ml are removed In addition, to simplify code, Libobject.record_object returning only the ('a->obj) function, which is enough almost all the time.
