Hi Kunal

You can build ART for host with the master-art manifest using:

$ cd $ANDROID_BUILD_TOP
$ . build/envsetup.sh
$ lunch silvermont-eng
$ art/tools/buildbot-build.sh --host

You can check your changes don't break existing tests unexpectedly running:

$ art/test.py --host -r -g

Good luck
Orion
