Comment #1 on issue 3864 by [email protected]: Support for node splitting in the Scheduler
https://code.google.com/p/v8/issues/detail?id=3864#c1
The following revision refers to this bug:https://chromium.googlesource.com/v8/v8.git/+/d8cfbc633d6f2fcc7016dfb8db8c3f7636c3151e
commit d8cfbc633d6f2fcc7016dfb8db8c3f7636c3151e Author: Benedikt Meurer <[email protected]> Date: Tue Feb 03 14:50:40 2015 [turbofan] Split pure nodes in the scheduler if beneficial. If a (pure) node has two or more uses, but there exists a path from the common dominator of these uses to end, which does not contain a use, then we split the node such that no unnecessary computation takes place. Note however, that this only applies if the node cannot be hoisted out of a loop.
