[aarch64-port-dev ] JDK-8253947: JEP 388 Windows/AArch64 backport to jdk11u

[Reka Kovacs]

Hi Christoph,

I will be substituting for Bernhard while he's on leave. Internally, we have the PR on top of 11.0.12+5, but will be rebasing it to jdk11u-dev/e62d6a2f3 this week. We are still going through our internal review and testing cycles to make sure we don't break any other platforms, running jtreg:all on all available architecture/OS combinations before and after the backport, and SPEC benchmarks similar to the original port testing.

As for the method of integration, I don't mind opening separate PRs if that makes reviews easier. Otherwise, thanks for looking into the merge option.

Best regards,
Reka

Hi,

now jdk11u-dev has switched to Github for the 11.0.13 CPU release. So it would be time to rebase the changes and open a PR here: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fopenjdk%2Fjdk11u-dev&data=04%7C01%7Crekakovacs%40microsoft.com%7C8b4645b914334f1159a608d92726c490%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637583869744063373%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=FMCQkTYN2KLwKXXE8M2slc2P%2FYrN42qPmH%2BDZ%2BxOTOM%3D&reserved=0

Once this PR has been reviewed and it's agreed that we want to merge the changes for JEP 388, we should not integrate it via the usual "/integrate" as this would squash all the single commits. I would then rather try to get it in via a "merge" PR - which I should be able to do as a maintainer of the Github repository. So, please let me know when the PR is ready and I'll have a look at the proper way to merge this.

Alternatively, we can go for each single backport but I guess it would be cumbersome in this case... ��

Best regards
Christoph
