Please review JDK-8134490 "Dead var statement evacuation incorrectly descends into nested functions" at <http://cr.openjdk.java.net/~attila/8134490/webrev.jdk9> for <https://bugs.openjdk.java.net/browse/JDK-8134490>
The essential change is the enterFunctionNode in Lower that returns false to avoid descending into nested functions. The change in FindScopeDepths is actually a code tightening; I was poking in there for the bug first, and I realized that it can be streamlined; !compiler.isOnDemandCompilation is always true, and instead of using enterDefault with instanceof IdentNode we can just use enterIdentNode… Thanks, Attila.
