[Qemu-devel] [PATCH 11/36] hw/s390x: Hard code size with MO_{8|16|32|64}
Posted by Richard Henderson 5 years, 7 months ago
From: Tony Nguyen <tony.nguyen@bt.com>

Temporarily no-op size_memop was introduced to aid the conversion of
memory_region_dispatch_{read|write} operand "unsigned size" into
"MemOp op".

Now size_memop is implemented, again hard coded size but with
MO_{8|16|32|64}. This is more expressive and avoids size_memop calls.
