starting at EA are stored from the GPRs rS through r31. For
example, if rS = 30, 2 words are stored. EA must be a multiple
of four. If it is not, either the system alignment exception handler
is invoked or the results are boundedly undefined.
Note that this instruction is likely to have a greater latency and
take longer to execute, perhaps much longer, than a sequence
of individual load or store instructions that produce the same
results.
