Each operation initiates the data read of a line
into cache in a state most efficient for writing (store). The data stream indicated
by arg3 is read beginning at address arg1
using the control
word in arg2. The arg1
type may also be a pointer to a const-qualified type. The result of the operation
is void.
vec_dstst indicates to the memory subsystem that the
data stream is relatively static, or persistent, in nature, while
vec_dststt indicates that the data stream is
relatively transient. Otherwise the instructions are identical.
See Software
Directed Prefetch for a discussion of
data streams and instructions that affect them.
