2019-03-01[Kernel] Simpler generation of opcode filesVincent Laporte
Files kernel/copcodes.ml, kernel/byterun/coq_instruct.h, and kernel/byterun/coq_jumptbl.h are generated by a simple OCaml program rather than a pipeline of sed and awk text processing.
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>

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.

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.
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

Part contre ces cas sont detruis dans les "Definition" (pas dans les "Lemma") je comprends pas ou ils sont enlev'e... Si une id'ee ... - Correction d'un bug dans vm_compute plusieurs fois signal'e par Roland. - Meilleur compilation des coinductifs, on utilise maintenant vraimment du lazy. - Enfin un peu plus de doc dans le code de la vm.
