Oops, fixed it.

I don't know but I've found https://github.com/bytecodealliance/wasmtime/issues/4566 so @uweigand might be able to confirm. The first section seems to be describing the ARM/MIPS behaviour where the element order in the ISA remains the same regardless of the endianness of the elements themselves . I don't see any of the required shuffling bitcasts in lib/Target/SystemZ for that behaviour though. That thread goes on to mention implementing all four combinations so it might be configurable
