The swift-arm.slack.com team has been working hard on bringing Swift to Linux AArch64 devices. This is everything from small SBC's like Raspberrypi 3 and the Rock64 to 96 core Cavium ThunderX Servers.
Thanks to https://www.worksonarm.com/cluster from https://www.packet.net/ we now have a dedicated AArch64 CI server - https://ci-external.swift.org/computer/ubuntu-16.04-aarch64/
We are now very close to having a release version of Swift 4.1.2 for Linux / AArch64.
Help with the following is needed to get us across the finish line.
PR  - https://github.com/apple/swift/pull/15174
This is currently blocking successful builds on the CI. Help is needed updating this PR and getting it approved.
Any help will be greatly appreciated.
