# 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
# 2ND_LIBART_BOOT_IMAGE=/system/framework/x86/boot.art
