of bytes to store. Let nr = CEIL( n
registers to supply data. n consecutive bytes starting at EA are
stored from GPRs rS through rS + nr – 1. Bytes are stored left to
right from each register. The sequence of registers wraps
around through r0 if required. If n = 0, no bytes are stored. Under
certain conditions (for example, segment boundary crossing) the
data alignment exception handler may be invoked.
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.
