-xprefetch[=(yes|no)]

SPARC: Uses prefetch instructions on UltraSPARC II processors.

With -xprefetch=yes, the compiler is free to insert prefetch instructions into the code it generates. This can result in a performance improvement on UltraSPARC II processors.

Defaults

If the -xprefetch option is not specified, the default is -xprefetch=no.

Specifying -xprefetch alone is equivalent to -xprefetch=yes.
