Lines Matching refs:prefetch

469 and @samp{prefetch}.  Another example are the set of V9
532 The @code{prefetch} and @code{prefetcha} instructions take a prefetch
533 function code. The following prefetch function code constant
538 @samp{#n_reads} requests a prefetch for several reads, and corresponds
539 to a prefetch function code of 0.
541 @samp{#one_read} requests a prefetch for one read, and corresponds
542 to a prefetch function code of 1.
544 @samp{#n_writes} requests a prefetch for several writes (and possibly
545 reads), and corresponds to a prefetch function code of 2.
547 @samp{#one_write} requests a prefetch for one write, and corresponds
548 to a prefetch function code of 3.
550 @samp{#page} requests a prefetch page, and corresponds to a prefetch
553 @samp{#invalidate} requests a prefetch invalidate, and corresponds to
554 a prefetch function code of 16.
556 @samp{#unified} requests a prefetch to the nearest unified cache, and
557 corresponds to a prefetch function code of 17.
559 @samp{#n_reads_strong} requests a strong prefetch for several reads,
560 and corresponds to a prefetch function code of 20.
562 @samp{#one_read_strong} requests a strong prefetch for one read,
563 and corresponds to a prefetch function code of 21.
565 @samp{#n_writes_strong} requests a strong prefetch for several writes,
566 and corresponds to a prefetch function code of 22.
568 @samp{#one_write_strong} requests a strong prefetch for one write,
569 and corresponds to a prefetch function code of 23.
571 Onle one prefetch code may be specified. Here are some examples:
574 prefetch [%l0 + %l2], #one_read
575 prefetch [%g2 + 8], #n_writes
580 The actual behavior of a given prefetch function code is processor
581 specific. If a processor does not implement a given prefetch
582 function code, it will treat the prefetch instruction as a nop.
