 # Rules to build boot.art
 # Input variables:
 #   my_2nd_arch_prefix: indicates if this is to build for the 2nd arch.

 # The image "location" is a symbolic path that with multiarchitecture
 # support doesn't really exist on the device. Typically it is
 # /system/framework/boot.art and should be the same for all supported
 # architectures on the device. The concrete architecture specific
 # content actually ends up in a "filename" that contains an
 # architecture specific directory name such as arm, arm64, mips,
 # mips64, x86, x86_64.
 #
 # Here are some example values for an x86_64 / x86 configuration:
 #
 # DEFAULT_DEX_PREOPT_BUILT_IMAGE_LOCATION=out/target/product/generic_x86_64/dex_bootjars/system/framework/boot.art
 # DEFAULT_DEX_PREOPT_BUILT_IMAGE_FILENAME=out/target/product/generic_x86_64/dex_bootjars/system/framework/x86_64/boot.art
 # LIBART_BOOT_IMAGE=/system/framework/x86_64/boot.art
 #
 # 2ND_DEFAULT_DEX_PREOPT_BUILT_IMAGE_LOCATION=out/target/product/generic_x86_64/dex_bootjars/system/framework/boot.art
 # 2ND_DEFAULT_DEX_PREOPT_BUILT_IMAGE_FILENAME=out/target/product/generic_x86_64/dex_bootjars/system/framework/x86/boot.art
