number of bytes to store. Let nr = CEIL( n
of 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. Under certain conditions (like
segment boundary crossing), the data alignment exception
handler may be invoked. In some implementations, this
instruction is likely to have a greater latency and take longer to
execute than a sequence of individual load or store instructions
that produce the same results.
