From: Stas Boukarev Date: Fri, 6 Sep 2013 22:03:08 +0000 (+0400) Subject: Improve knownfun declarations. X-Git-Url: http://repo.macrolet.net/gitweb/?a=commitdiff_plain;h=01cc13c8dab7399f6d7ef10e01add5edbbc03e31;p=sbcl.git Improve knownfun declarations. Make some types more accurate, add some :derive-type #'result-type-first/last-arg. Add missing %adjoin/member/assoc-test/not/key defknowns. --- diff --git a/package-data-list.lisp-expr b/package-data-list.lisp-expr index 631504b..8ebecda 100644 --- a/package-data-list.lisp-expr +++ b/package-data-list.lisp-expr @@ -1866,6 +1866,7 @@ is a good idea, but see SB-SYS re. blurring of boundaries."
