72  *
73  * Slot 1 store with slot 0 load
74  * A slot 1 store operation with a slot 0 load operation can appear in a packet.
75  * The packet attribute :mem_noshuf inhibits the instruction reordering that
76  * would otherwise be done by the assembler. For example:
77  *     {
78  *         memw(R5) = R2 // slot 1 store
79  *         R3 = memh(R6) // slot 0 load
80  *     }:mem_noshuf
81  * Unlike most packetized operations, these memory operations are not executed
82  * in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
83  * effectively executes first, followed by the load instruction in Slot 0. If
84  * the addresses of the two operations are overlapping, the load will receive
85  * the newly stored data. This feature is supported in processor versions
86  * V65 or greater.
87  *
88  *
89  * For qemu, we look for a load in slot 0 when there is  a store in slot 1
90  * in the same packet.  When we see this, we call a helper that probes the
91  * load to make sure it doesn't fault.  Then, we process the store ahead of
92  * the actual load.
