# Some versions of dalvik had a bug where you cannot use the second half of an input long
# as the first part of an output long. This smali code explicitly has that issue so the
# generated dex file can be used to test art/dalvik versions.
# The issue was that if you have
# add-long v3, v0, v2
# dalvik would add v0 and v2 and store the result in v3 before adding v1 and v3 (now clobbered).
