2020-07-06Primitive persistent arraysMaxime Dénès
Persistent arrays expose a functional interface but are implemented using an imperative data structure. The OCaml implementation is based on Jean-Christophe Filliâtre's. Co-authored-by: Benjamin Grégoire <Benjamin.Gregoire@inria.fr> Co-authored-by: Gaëtan Gilbert <gaetan.gilbert@skyskimmer.net>
2020-03-18Update headers in the whole code base.Théo Zimmermann
Add headers to a few files which were missing them.
2019-11-21[coq] Untabify the whole ML codebase.Emilio Jesus Gallego Arias
We also remove trailing whitespace. Script used: ```bash for i in `find . -name '*.ml' -or -name '*.mli' -or -name '*.mlg'`; do expand -i "$i" | sponge "$i"; sed -e's/[[:space:]]*$//' -i.bak "$i"; done ```

2019-02-04Primitive integersMaxime Dénès
This work makes it possible to take advantage of a compact representation for integers in the entire system, as opposed to only in some reduction machines. It is useful for heavily computational applications, where even constructing terms is not possible without such a representation. Concretely, it replaces part of the retroknowledge machinery with a primitive construction for integers in terms, and introduces a kind of FFI which maps constants to operators (on integers). Properties of these operators are expressed as explicit axioms, whereas they were hidden in the retroknowledge-based approach. This has been presented at the Coq workshop and some Coq Working Groups, and has been used by various groups for STM trace checking, computational analysis, etc. Contributions by Guillaume Bertholon and Pierre Roux <Pierre.Roux@onera.fr> Co-authored-by: Benjamin Grégoire <Benjamin.Gregoire@inria.fr> Co-authored-by: Vincent Laporte <Vincent.Laporte@fondation-inria.fr>
2018-09-17[VM] Move structured_constant to VmvaluesMaxime Dénès
2018-07-24VM: don't duplicate projection narg information in lproj/kprojGaëtan Gilbert
2018-07-24Projections use index representationGaëtan Gilbert
The upper layers still need a mapping constant -> projection, which is provided by Recordops.
2018-06-27Fix #7723: vm_compute segfaults with universe polymorphismMaxime Dénès
Was revealing a critical bug in VM universe handling introduced in 8.5.
2018-06-10[VM] Remove projection names from structured constants.Maxime Dénès
It was actually a hack since those names are never used to represent values, only to be passed as arguments to bytecode instructions. So instead of reusing the structured_constant type, we follow the same pattern as switch annotations.

2018-03-04Merge PR #935: Handling evars in the VMMaxime Dénès
2018-03-03Handling evars in the VM.Pierre-Marie Pédrot
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.
2018-03-02[VM] Unify Const_sorts and Const_type, and remove Vsort.Maxime Dénès
This simplifies the representation of values, and brings it closer to the ones of the native compiler.

2018-02-23New IR in VM: Clambda.Maxime Dénès
This intermediate representation serves two purposes: 1- It is a preliminary step for primitive machine integers, as iterators will be compiled to Clambda. 2- It makes the VM compilation passes closer to the ones of native_compute. Once we unifiy the representation of values, we should be able to factorize the lambda-code generation between the two compilers, as well as the reification code. This code was written by Benjamin Grégoire and myself.
2018-02-14Factorize the relocations in the on-disk VM representation.Pierre-Marie Pédrot
Instead of using a linear representation, we simply use a table that maps every kind of relocation to the list of positions it needs to be applied to.

We do up to `Term` which is the main bulk of the changes.

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.
2016-08-22Use a better data structure for VM compilation of free vars.Pierre-Marie Pédrot
This fixes #3450 and probably provides a huge speed-up to many instances.

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.

2015-07-05Fix 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.
2015-06-23Add a Set Dump Bytecode command for debugging purposes.Maxime Dénès
Prints the VM bytecode produced by compilation of a constant or a call to vm_compute.

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.

dev/ocamlweb-doc has been erased. I hope no one still use the "new-parse" it generate. In dev/, make html will generate in dev/html/ "clickable version of mlis". (as the caml standard library) make coq.pdf will generate nearly the same awfull stuff that coq.ps was. make {kernel,lib,parsing,..}.{dot,png} will do the dependancy graph of the given directory. ocamldoc comment syntax is here : http://caml.inria.fr/pub/docs/manual-ocaml/manual029.html The possibility to put graphs in pdf/html seems to be lost. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12969 85f007b7-540e-0410-9357-904b9bb8a0f7
