starting at EA are loaded into GPRs rD through r31.
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. If rA is in the range of registers specified
to be loaded, including the case in which rA = 0, the instruction
form is invalid.
Note that, in some implementations, 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.
