From e43b1768d0f8399f426b92f4dfe31955daceb1a4 Mon Sep 17 00:00:00 2001 From: Maxime Dénès Date: Fri, 16 Feb 2018 01:02:17 +0100 Subject: Primitive integers 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 Co-authored-by: Benjamin Grégoire Co-authored-by: Vincent Laporte --- dev/top_printers.ml | 4 ++++ dev/vm_printers.ml | 1 + 2 files changed, 5 insertions(+) (limited to 'dev') diff --git a/dev/top_printers.ml b/dev/top_printers.ml index 8f207d1e0a..2629cf8626 100644 --- a/dev/top_printers.ml +++ b/dev/top_printers.ml @@ -292,6 +292,8 @@ let constr_display csr = ^(Array.fold_right (fun x i -> (name_display x)^(if not(i="") then (";"^i) else "")) lna "")^"," ^(array_display bl)^")" + | Int i -> + "Int("^(Uint63.to_string i)^")" and array_display v = "[|"^ @@ -421,6 +423,8 @@ let print_pure_constr csr = print_cut(); done in print_string"{"; print_fix (); print_string"}" + | Int i -> + print_string ("Int("^(Uint63.to_string i)^")") and box_display c = open_hovbox 1; term_display c; close_box() diff --git a/dev/vm_printers.ml b/dev/vm_printers.ml index ea126e2756..dc30793a6e 100644 --- a/dev/vm_printers.ml +++ b/dev/vm_printers.ml @@ -82,6 +82,7 @@ and ppwhd whd = | Vcofix _ -> print_string "cofix" | Vconstr_const i -> print_string "C(";print_int i;print_string")" | Vconstr_block b -> ppvblock b + | Vint64 i -> printf "int64(%LiL)" i | Vatom_stk(a,s) -> open_hbox();ppatom a;close_box(); print_string"@";ppstack s -- cgit v1.2.3
