The following revision refers to this bug: https://chromium.googlesource.com/v8/v8.git/+/a757a62bf5106086250e61eb3a17db888c8a37e3 commit a757a62bf5106086250e61eb3a17db888c8a37e3 Author: mstarzinger <mstarzinger@chromium.org> Date: Fri Jul 01 13:51:51 2016 [turbofan] Broaden checkpoint elimination on returns. This makes the elimination of checkpoints flowing effect-wise into nodes having the {Return} operator more permissive. We can cut out checkpoints even when they are not wholly owned by the return. This also alleviates a problem where TCO no longer applies.
