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 --- doc/sphinx/user-extensions/syntax-extensions.rst | 4 ++-- doc/stdlib/index-list.html.template | 9 ++++++--- 2 files changed, 8 insertions(+), 5 deletions(-) (limited to 'doc') diff --git a/doc/sphinx/user-extensions/syntax-extensions.rst b/doc/sphinx/user-extensions/syntax-extensions.rst index ae66791b0c..105b0445fd 100644 --- a/doc/sphinx/user-extensions/syntax-extensions.rst +++ b/doc/sphinx/user-extensions/syntax-extensions.rst @@ -1497,12 +1497,12 @@ Numeral notations for only non-negative integers, and the given numeral is negative. - .. exn:: @ident should go from Decimal.int to @type or (option @type).
