From 89a85a6603b7112e685a052d728284d3e4c2881e Mon Sep 17 00:00:00 2001 From: Gaëtan Gilbert Date: Fri, 11 May 2018 23:07:14 +0200 Subject: Fix #7421: constr_eq ignores universe constraints. The test isn't quite the one in #7421 because that use of algebraic universes is wrong. --- doc/sphinx/proof-engine/tactics.rst | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'doc/sphinx') diff --git a/doc/sphinx/proof-engine/tactics.rst b/doc/sphinx/proof-engine/tactics.rst index 29c2f8b81..d0a0d568e 100644 --- a/doc/sphinx/proof-engine/tactics.rst +++ b/doc/sphinx/proof-engine/tactics.rst @@ -3949,9 +3949,20 @@ succeeds, and results in an error otherwise. :name: constr_eq This tactic checks whether its arguments are equal modulo alpha - conversion and casts. + conversion, casts and universe constraints.
