; RUN: llc -march=hexagon < %s | FileCheck %s

; Check that this testcase compiles successfully.
; Because l2fetch has mayLoad/mayStore flags on it, the packetizer
; was tricked into thinking that it's a store. The v65-specific
; code dealing with mem_shuff allowed it to be packetized together
; with the load.
