        Description

        Issue 8068945 (https://bugs.openjdk.java.net/browse/JDK-8068945) allows x86 to use RBP as a proper frame pointer for debug and profiling.

        This was fixed in http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/rev/382e9e4b3b71

        This issue proposes a similar enhancement for aarch64.

        I have a patch under preparation which I will post for review shortly
