[PATCH 00/14] target/s390x: Clean up mem ops and byte swapping

Posted by Richard Henderson 1 month, 4 weeks ago

Once upon a time we didn't have controllable endianness in our memory ops,
so we were forced to perform the bswap for LOAD/STORE REVERSED manually.
But that hasn't been true for quite some time.  Tidy up all of the simple
loads and stores by stashing the complete MemOp for each instruction.
