The following revision refers to this bug: https://chromium.googlesource.com/v8/v8.git/+/ec0e9e6a400df0789b5269cd3c6b84b351d249e2 commit ec0e9e6a400df0789b5269cd3c6b84b351d249e2 Author: mstarzinger <mstarzinger@chromium.org> Date: Mon Sep 26 11:38:51 2016 [turbofan] Handle simplified ops in escape analysis. This adds handling of simplified ops without effect input to the escape status analysis. Such uses are treated as escaping for now until we add dedicated handling to the escape analysis reducer.
