Subject: [Qemu-devel] [PATCH v9 04/20] hw/s390x: Access MemoryRegion with MemOp
Date: Sat, 24 Aug 2019 04:36:42 +1000 [thread overview]
Message-ID: <2f41da26201fb9b0339c2b7fde34df864f7f9ea8.1566466906.git.tony.nguyen@bt.com> (raw)
In-Reply-To: <cover.1566466906.git.tony.nguyen@bt.com>
The memory_region_dispatch_{read|write} operand "unsigned size" is
being converted into a "MemOp op".
Convert interfaces by using no-op size_memop.
After all interfaces are converted, size_memop will be implemented
and the memory_region_dispatch_{read|write} operand "unsigned size"
will be converted into a "MemOp op".
As size_memop is a no-op, this patch does not change any behaviour.
