Art versions in the directory, and where they were build from
-------------------------------------------------------------
See https://source.android.com/source/build-numbers.html for build numbers.

Build from AOSP branch master. To update to a new AOSP master
mkdir master
cd master
repo init -u https://android.googlesource.com/platform/manifest -b master
repo sync -cq -j24
source build/envsetup.sh
lunch aosp_angler-eng
m -j24
m -j24 build-art
m -j24 test-art-host
Collected into tools/linux/art
scripts/update-host-art.sh --android-checkout ~/android/master --art-dir art
The precise info for the AOSP master used is in aosp_master_manifest.xml, which is
produced using this command:
repo manifest -o aosp_master_manifest.xml -r
To reproduce that AOSP state, use the following commands:
mkdir master
cd master
mkdir -p .repo/manifests
cp <r8-checkout>/aosp_master_manifest.xml .repo/manifests
repo init -u https://android.googlesource.com/platform/manifest -m aosp_master_manifest.xml
<continue with repo sync as above>
