[aarch64-port-dev ] [jdk11u] 8253947: Implementation: JEP 388: Windows AArch64 Support

[Ludovic Henry]

Hi,

As we are getting closer to merge JEP 388 (Windows/AArch64 Port), I wanted to share the work I've done for the backport to JDK 11.

This email is not an RFR as the webrev is not finalized yet (the JEP implementation hasn't landed on JDK tip). I'm sharing it just to give an idea of the work which will be required, what kind of changes we are facing, and for other parties who have expressed interest in this backport. I'll keep updating it as we get reviews on [1].

Once we've landed the JEP implementation into JDK tip, I'll create the appropriate bug IDs for all the necessary backports, and contact the relevant mailing lists with the different webrevs and JBS.

I've tested this change on Windows-AArch64 against hotspot:tier1, jdk:tier1 and langtools, but not yet on Linux-AArch64.

Webrev: http://cr.openjdk.java.net/~luhenry/8253947/webrev.00/

Thank you,
Ludovic
