2# ART boot image installation
3# Input variables:
4#   my_boot_image_name: the boot image to install
5#   my_boot_image_arch: the architecture to install (e.g. TARGET_ARCH, not expanded)
6#   my_boot_image_out:  the install directory (e.g. $(PRODUCT_OUT))
7#   my_boot_image_syms: the symbols director (e.g. $(TARGET_OUT_UNSTRIPPED))
8#
9# Output variables:
10#   my_boot_image_module: the created module name. Empty if no module is created.
11#
12# Install the boot images compiled by Soong.
13# Create a module named dexpreopt_bootjar.$(my_boot_image_name)_$($(my_boot_image_arch))
14# that installs all of boot image files.
15# If there is no file to install for $(my_boot_image_name), for example when
16# building an unbundled build, then no module is created.
