[aarch64-port-dev ] RFR: 8168503 JEP 297: Unified arm32/arm64 Port

[Vladimir Kozlov]

hi Bob,

I would suggest to have separate webrevs for different repositories because different groups should look on them.

For example, top repository and makefiles changes should be also reviewed on build-dev at openjdk.java.net

Why do you need cahnges in SA libproc.h?

I saw Hotspot changes before and I think they are fine (did not dive deep).

Thanks,
Vladimir
