in memory at
EA = (RA|0) + (RB).
Update the base address,
(RA)
← EA.

EA = (RA|0) + (RB).
316
stmw RS, D(RA) Store consecutive words from RS through GPR(31) in
memory starting at
EA = (RA|0) + EXTS(D).
317
stswi RS, RA, NB Store consecutive bytes in memory starting at EA=(RA|0).
Number of bytes n=32 if NB=0, else n=NB.
Bytes are unstacked from CEIL(n/4)
consecutive registers starting with RS.
GPR(0) is consecutive to GPR(31).
318
stswx RS, RA, RB Store consecutive bytes in memory starting at
EA=(RA|0)+(RB).
Number of bytes n=XER[TBC].
Bytes are unstacked from CEIL(n/4)
consecutive registers starting with RS.
GPR(0) is consecutive to GPR(31).
