Thanks Vladimir and Andrew! > 1) support for macos/aarch64 is not just jep-391, we split our jep into pieces, > some of them were macos/aarch64 independent and were pushed to upstream > as separate commits ( for example, macos MAP_JIT support). also some > important pieces from community ( like JNF dependency removal by Phil Race). > All these pieces need to be backported before jep-391. For JEP 388 we have a similar situation, although those independent changes are at a smaller scale I would say. For example let's have a look at JDK-8248403 [1], does it need its own PR on the jdk11u repository or is it fine package it all together in one big PR? Here is a rebased jdk11u branch btw: https://github.com/lewurm/jdk11u/commits/jdk11u-windows > 2) we have a plan to go in a traditional way, ojdk17 -> ojdk15 -> ojdk13 > -> ojdk11 I would say jdk13u/jdk15u is low-priority for us, but I can have a look at them for JEP 388 once I've figured out the process for jdk11u (assuming it's the same). > Cross compilation is not a requirement for a backport. Cross compilation is the only way to build Windows+Arm64 today, so we need at least the hacky variant that I suggested.

All these pieces need to be backported before jep-391. 2) we have a plan to go in a traditional way, ojdk17 -> ojdk15 -> ojdk13 -> ojdk11 If you don’t want to bother with jdk15/13 I would suggest you to go without waiting for jep-391.

JEP 391 (macOS/AArch64) has a dependency on JEP 388, and I'm assuming we want both to be backported. Question: Is it preferred to do it one go (both together), or should we do it separately (that would be Windows first, then macOS)? > > 2. JEP 388 includes build changes to add cross compilation support for Windows in a hacky way. It's enough to get a build out of it [1], but it's not exactly clean. It was eventually cleaned up with the "WINENV" patch by Magnus [2], but imho it isn't trivial to backport that change. Thoughts? > > > Assuming the answer to question 1 is to split the backports: I think https://github.com/openjdk/aarch64-port/tree/jdk11-windows by Ludovic is in an okay shape, but I will take it for a spin tomorrow and then submit an initial PR against https://github.com/openjdk/jdk11u > > > Thank you, > -Bernhard > > > [1] with workarounds: https://github.com/openjdk/jdk/pull/212#issuecomment-695024586 > [2] https://github.com/openjdk/jdk/pull/1597
