/*
 * 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 probes the
 * load to make sure it doesn't fault.  Then, we process the store ahead of
 * the actual load.
