72  * Section 5.5 of the Hexagon V67 Programmer's Reference Manual
73  *
74  * Slot 1 store with slot 0 load
75  * A slot 1 store operation with a slot 0 load operation can appear in a packet.
76  * The packet attribute :mem_noshuf inhibits the instruction reordering that
77  * would otherwise be done by the assembler. For example:
78  *     {
79  *         memw(R5) = R2 // slot 1 store
80  *         R3 = memh(R6) // slot 0 load
81  *     }:mem_noshuf
82  * Unlike most packetized operations, these memory operations are not executed
83  * in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
84  * effectively executes first, followed by the load instruction in Slot 0. If
85  * the addresses of the two operations are overlapping, the load will receive
86  * the newly stored data. This feature is supported in processor versions
87  * V65 or greater.
88  *
89  *
90  * For qemu, we look for a load in slot 0 when there is  a store in slot 1
91  * in the same packet.  When we see this, we call a helper that merges the
92  * bytes from the store buffer with the value loaded from memory.
