Sun Studio 12 Update 1: Fortran User's Guide

3.4.157.2 Interactions:

With -xprefetch=explicit, the compiler will recognize the directives:

$PRAGMA SUN_PREFETCH_READ_ONCE (name)

$PRAGMA SUN_PREFETCH_READ_MANY (name)

$PRAGMA SUN_PREFETCH_WRITE_ONCE (name)

$PRAGMA SUN_PREFETCH_WRITE_MANY (name)

The -xchip setting effects the determination of the assumed latencies and therefore the result of a latx:factor setting.

The latx:factor suboption is valid only when automatic prefetching (auto) is enabled on SPARC processors.
