# RUN: llc -march=hexagon -run-pass hexagon-packetizer %s -o - | FileCheck %s

# Make sure that we don't try to packetize the two stores together. The
# dependence on $r0 could be broken by updating the offset in the storeiri,
# but then the offset would become invalid for that instruction (it has to
# be a multiple of 4).

# CHECK: S4_storeiri_io killed $r0, 0, 0
