<dl>
|

<dt><code>sw2 __IACCreadll (iacc </code><var>reg</var><code>)</code><dd>Return the full 64-bit value of IACC0. The <var>reg</var> argument is reserved
|

|
|
for future expansion and must be 0.
|
||
|
|
|
||
|
|
<br><dt><code>sw1 __IACCreadl (iacc </code><var>reg</var><code>)</code><dd>Return the value of IACC0H if <var>reg</var> is 0 and IACC0L if <var>reg</var> is 1.
|
||
|
|
Other values of <var>reg</var> are rejected as invalid.
|

|
|
|
||
|
|
<br><dt><code>void __IACCsetll (iacc </code><var>reg</var><code>, sw2 </code><var>x</var><code>)</code><dd>Set the full 64-bit value of IACC0 to <var>x</var>. The <var>reg</var> argument
|

is reserved for future expansion and must be 0.

|
|
|

is 1. Other values of <var>reg</var> are rejected as invalid.
|

<br><dt><code>void __data_prefetch0 (const void *</code><var>x</var><code>)</code><dd>Use the <code>dcpl</code> instruction to load the contents of address <var>x</var>

into the data cache.
|

<br><dt><code>void __data_prefetch (const void *</code><var>x</var><code>)</code><dd>Use the <code>nldub</code> instruction to load the contents of address <var>x</var>
