# Generates the final .pak file allowlist that can be used by repack()'s
# repack_allowlist parameter. Used resources are tracked by the toolchain when
# enable_resource_allowlist_generation = true and are stored in the unstripped
# binary's debug info. This action extracts the allowlist from the binary.
#
# Variables
# input: Path to the unstripped .so file.
# output: Path to write the output allowlist to.
#
# Example
# generate_resource_allowlist("pak_allowlist") {
# deps = [ ":my_shared_lib" ]
# input = "$root_out_dir/lib.unstripped/libmy_shared_lib$shlib_extension"
# output = "$target_gen_dir/pak_allowlist.txt"
# }
