ATTENTION: hg: jdk9/hs-comp/hotspot: 8149418: AArch64: replace tst+br with tbz instruction when tst's constant operand is 2 power

[Vladimir Kozlov]

Please, don't push RFE(Enhancement) changes without approval. Even if it is platform specific code.

We passed FC (Feature Complete) date May 26:

http://openjdk.java.net/projects/jdk9

All RFE(Enhancement) changes for JDK 9 should be approved before pushing them. Or target RFE for JDK 10.

If changes are ready you still need to get approval. Unfortunately the procedure for openjdk contribution approval is 
not finalized yet. Please, wait a little. For now add FC exemption request comment if you want to push into JDK 9. See 
for example:

https://bugs.openjdk.java.net/browse/JDK-8156839

Note, if shared code (or platforms specific code which Oracle support) is changed by RFE it will be a lot harder to get 
approval.

Regards,
Vladimir
