# RUN: llc -march=hexagon -mcpu=hexagonv62  -run-pass amode-opt %s -o -
# REQUIRES: asserts
#
# This test merely checks if the pass that optimizes addressing modes in the
# hexagon backend doesn't crash when the following code is presented to it.
#
# This is a testcase reduced from code generated by the Halide compiler for a
# Halide pipeline. This code was causing the pass 'amode-opt' to crash because
# it was looking for the third operand (offset) in the following instruction
# that does not, in fact, have a third operand.
#
#          $r1 = L2_loadw_locked $r1
#
# Check that this doesn't crash.
