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

5# The image "location" is a symbolic path that with multiarchitecture
6# support doesn't really exist on the device. Typically it is
7# /system/framework/boot.art and should be the same for all supported
8# architectures on the device. The concrete architecture specific
9# content actually ends up in a "filename" that contains an
10# architecture specific directory name such as arm, arm64, mips,
11# mips64, x86, x86_64.
12#
13# Here are some example values for an x86_64 / x86 configuration:
14#

16# DEFAULT_DEX_PREOPT_BUILT_IMAGE_FILENAME=out/target/product/generic_x86_64/dex_bootjars/system/framework/x86_64/boot.art
17# LIBART_BOOT_IMAGE=/system/framework/x86_64/boot.art

19# 2ND_DEFAULT_DEX_PREOPT_BUILT_IMAGE_LOCATION=out/target/product/generic_x86_64/dex_bootjars/system/framework/boot.art
