| * | Handling evars in the VM.Gravatar Pierre-Marie Pédrot2018-03-03
| | | | | | | | | | | | | | | | | | | | | We simply treat them as as an application of an atom to its instance, and in the decompilation phase we reconstruct the instance from the stack. This grants wish BZ#5659.

* Safer VM interfacesGravatar Maxime Dénès2018-01-26
| | | | | | | | | | | | We separate functions dealing with VM values (vmvalues.ml) and interfaces of the bytecode interpreter (vm.ml). Only the former relies on untyped constructions. This also makes the VM architecture closer to the one of native_compute, another patch could probably try to share more code between the two for conversion and reification (not trivial, though). This is also preliminary work for integers and arrays.

| * Fix #5127 Memory corruption with the VMGravatar Maxime Dénès2016-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Refine Gregory Malecha's patch on VM and universe polymorphism.Gravatar Maxime Dénès2015-10-28
| | | | | | | | | | | | | | | | - 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.

| | | | | 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.

* Correct restriction of vm_compute when handling universe polymorphicGravatar Matthieu Sozeau2015-01-15
| | | | | | | | | | 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.

* Monomorphized a lot of equalities over OCaml integers, thanks toGravatar ppedrot2012-11-08
| | | | | | | | | | | | | | | | | 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
* Remove some dead code in the vmGravatar letouzey2012-10-02
| | | | | | | | | | | | | 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
