__attribute__() [1/3]

__inline__ short __attribute__ ( (__always_inline__, __nodebug__, __target__("movbe")) ) const

static

Load a 16-bit value from memory and swap its bytes.

Swap the bytes of a 32-bit value and store it to memory.

Load a 32-bit value from memory and swap its bytes.

Swap the bytes of a 16-bit value and store it to memory.

This intrinsic corresponds to the MOVBE instruction.

Parameters

__P	A pointer to the 16-bit value to load.

Returns

The byte-swapped value.

This intrinsic corresponds to the MOVBE instruction.

Parameters

__P	A pointer to the memory for storing the swapped value.
__D	The 16-bit value to be byte-swapped.

This intrinsic corresponds to the MOVBE instruction.

Parameters

__P	A pointer to the 32-bit value to load.

Returns

The byte-swapped value.

This intrinsic corresponds to the MOVBE instruction.

Parameters

__P	A pointer to the memory for storing the swapped value.
__D	The 32-bit value to be byte-swapped.

__attribute__() [2/3]

__inline__ unsigned int __attribute__ ( (__always_inline__, __nodebug__, __target__("rdpid")) )

static

Reads the value of the IA32_TSC_AUX MSR (0xc0000103).

This intrinsic corresponds to the RDPID instruction.

Returns

The 32-bit contents of the MSR.

__attribute__() [3/3]

__inline__ int __attribute__ ( (__always_inline__, __nodebug__, __target__("rdrnd")) )

static

Returns a 16-bit hardware-generated random value.

Returns a 64-bit hardware-generated random value.

Returns a 32-bit hardware-generated random value.

This intrinsic corresponds to the RDRAND instruction.

Parameters

__p	A pointer to a 16-bit memory location to place the random value.

Returns

1 if the value was successfully generated, 0 otherwise.

This intrinsic corresponds to the RDRAND instruction.

Parameters

__p	A pointer to a 32-bit memory location to place the random value.

Returns

1 if the value was successfully generated, 0 otherwise.

This intrinsic corresponds to the RDRAND instruction.

Parameters

__p	A pointer to a 64-bit memory location to place the random value.

Returns

1 if the value was successfully generated, 0 otherwise.
