63  *
64  * Slot 1 store with slot 0 load
65  * A slot 1 store operation with a slot 0 load operation can appear in a packet.
66  * The packet attribute :mem_noshuf inhibits the instruction reordering that
67  * would otherwise be done by the assembler. For example:
68  *     {
69  *         memw(R5) = R2 // slot 1 store
70  *         R3 = memh(R6) // slot 0 load
71  *     }:mem_noshuf
72  * Unlike most packetized operations, these memory operations are not executed
73  * in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
74  * effectively executes first, followed by the load instruction in Slot 0. If
75  * the addresses of the two operations are overlapping, the load will receive
76  * the newly stored data. This feature is supported in processor versions
77  * V65 or greater.
78  *
79  *
80  * For qemu, we look for a load in slot 0 when there is  a store in slot 1
81  * in the same packet.  When we see this, we call a helper that probes the
82  * load to make sure it doesn't fault.  Then, we process the store ahead of
83  * the actual load.
