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