The quadword in the specified register is stored into memory.
The memory address that is computed is truncated to a multiple of 8
(i.e., the 3 bottom bits of the effective address are cleared).

.section Store S_floating (Store Longword) (sts)
.syntax
    sts &opnd9
.esyntax
.descrp
The 4-byte S_floating (or Longword Integer) datum in the specified
register is stored into memory.
The location must be longword aligned.

.section Store T_floating (Store Quadword) (stt)
.syntax
    stt &opnd9
.esyntax
.descrp
The 8-byte T_floating (or Quadword Integer) datum in the specified
register is stored into memory.
The location must be quadword aligned.

.section Prefetch Data (fetch)
.syntax
    fetch address
.esyntax
.descrp
The specified address is used to designate an aligned 512-byte block
of data.
An implementation may optionally attempt to move all or part of this
block (or a larger surrounding block) of data to a faster-access part
of the memory hierarchy, in anticipation of subsequent Load or Store
instructions that access the data.

.section Prefetch Data, Modify Intent (fetch_m)
.syntax
    fetch_m address
.esyntax
.descrp
The specified address is used to designate an aligned 512-byte block
of data.
An implementation may optionally attempt to move all or part of this
block (or a larger surrounding block) of data to a faster-access part
of the memory hierarchy, in anticipation of subsequent Load or Store
instructions that access the data.
.np
The fetch_m instruction differs from the fetch instruction in that
it gives the additional hint that modifications (stores) to some or
all of the data block are anticipated.

.section Memory Barrier (mb)
.syntax
    mb
.esyntax
.descrp
Memory Barrier is used to serialize access to memory.
It is only required in multiprocessor systems.
In the absence of an mb instruction, loads and stores to different
physical locations are allowed to complete out of order on the issuing
processor as observed by other processors.

.section Write Memory Barrier (wmb)
.syntax
    wmb
.esyntax
.descrp
Write Memory Barrier guarantees that all previous store instructions
access memory before any store instructions issued after the wmb
instruction.
