| # 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. |
