From: mstarzinger@chromium.org Date: Fri, 1 Mar 2013 12:23:24 +0000 (+0000) Subject: Unify deoptimizer for accessor and arguments frames. X-Git-Tag: upstream/4.7.83~14987 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05f1be1bb3b1fae759c381ad19c5c6ca39d36b55;p=platform%2Fupstream%2Fv8.git Unify deoptimizer for accessor and arguments frames. This unifies the translation of artificial accessor stub and arguments adaptor frames. The frame layout is the same on all architectures and the computation code can be shared.
