Test: m out/host/linux-x86/apex/art_boot_images/javalib/x86_64/boot.oat

Test: m droid
  on master and check that
  out/soong/.intermediates/art/build/apex/com.android.art/android_common_com.android.art_image/image.apex/javalib/x86_64/boot.oat
  and out/target/product/vsoc_x86_64/system/framework/x86_64/boot-framework.oat
  are identical.
