Other-General Support-XMM

Register:

XMM 128 bit

Return Type:

void

Param Types:

void const* p, unsigned extensions, unsigned hints

Param ETypes:

p,

UI32 extensions, UI32 hints

void _mm_monitor(void const* p, unsigned extensions,
                 unsigned hints)

Intel Description

Arm address monitoring hardware using the address specified in “p”. A store to an address within the specified address range triggers the monitoring hardware. Specify optional extensions in “extensions”, and optional hints in “hints”.

Return Type:

void

Param Types:

char const* p, int i

Param ETypes:

UI8 p, IMM i

void _mm_prefetch(char const* p, int i);

Intel Description

Fetch the line of data from memory that contains address “p” to a location in the cache hierarchy specified by the locality hint “i”, which can be one of:<ul>

<li>_MM_HINT_ET0 // 7, move data using the ET0 hint. The PREFETCHW instruction will be generated.</li> <li>_MM_HINT_T0 // 3, move data using the T0 hint. The PREFETCHT0 instruction will be generated.</li> <li>_MM_HINT_T1 // 2, move data using the T1 hint. The PREFETCHT1 instruction will be generated.</li> <li>_MM_HINT_T2 // 1, move data using the T2 hint. The PREFETCHT2 instruction will be generated.</li> <li>_MM_HINT_NTA // 0, move data using the non-temporal access (NTA) hint. The PREFETCHNTA instruction will be generated.</li>
