The pkt_has_store_s1 field is only used for bookkeeping helpers with a load. With recent changes that eliminate the need to free TCGv variables, it makes more sense to make this transient. These helpers already take the instruction slot as an argument. We combine the slot and pkt_has_store_s1 into a single argument called slotval.

|
|
* 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.
