-xprefetch[={yes|no}]

Use prefetch instructions on Ultrasparc II platforms.

SPARC: 77/90

Specifying -xprefetch=yes enables the compiler to insert prefetch instructions whenever appropriate. This may result in a performance improvement on UltraSPARC II processors.

If not specified, the compiler assumes -xprefetch=no. -xprefetch specified by itself defaults to -xprefetch=yes.
