# 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.
