Hi Sandhya

Thanks very much for your works.
To make AArch64 backend review easier and reduce conflicts with jdk master, I'm
refactoring AArch64 backend recently. I have merged these patches and initiate AArch64
backend reviews on hotspot-compile-dev. Please check it.


Could you update latest webrevs in https://bugs.openjdk.java.net/browse/JDK-8223347.
So that I can check them.

Hi Yang,

We are getting closer and closer to JDK 15 deadline and don't have much time left.
Please do initiate Aarch64 backend reviews on hotspot-compile-dev ASAP.
I have enclosed the link [1] to x86 backend review request for your reference.

We have already received reviews on Runtime, Compiler,  x86 backend and the API.
Also, we are making good progress on CSR front.
The CSR is in provisional state and we are requesting next set of reviews today to finalize it.

We are hoping to propose the vector API JEP to target this week and it is important to get Aarch64 backend reviews in.

Best Regards,
