Function Documentation

_mm_crc32_u16()

__inline__ unsigned int __DEFAULT_FN_ATTRS _mm_crc32_u16 ( unsigned int __C, unsigned short __D )

static

Adds the unsigned integer operand to the CRC-32C checksum of the unsigned short operand.

This intrinsic corresponds to the CRC32W instruction.

Parameters

__C	An unsigned integer operand to add to the CRC-32C checksum of operand __D.
__D	An unsigned 16-bit integer operand used to compute the CRC-32C checksum.

Returns

The result of adding operand __C to the CRC-32C checksum of operand __D.

_mm_crc32_u32()

__inline__ unsigned int __DEFAULT_FN_ATTRS _mm_crc32_u32 ( unsigned int __C, unsigned int __D )

static

Adds the first unsigned integer operand to the CRC-32C checksum of the second unsigned integer operand.

This intrinsic corresponds to the CRC32L instruction.

Parameters

__C	An unsigned integer operand to add to the CRC-32C checksum of operand __D.
__D	An unsigned 32-bit integer operand used to compute the CRC-32C checksum.

Returns

The result of adding operand __C to the CRC-32C checksum of operand __D.

_mm_crc32_u8()

__inline__ unsigned int __DEFAULT_FN_ATTRS _mm_crc32_u8 ( unsigned int __C, unsigned char __D )

static

Adds the unsigned integer operand to the CRC-32C checksum of the unsigned char operand.

This intrinsic corresponds to the CRC32B instruction.

Parameters

__C	An unsigned integer operand to add to the CRC-32C checksum of operand __D.
__D	An unsigned 8-bit integer operand used to compute the CRC-32C checksum.

Returns

The result of adding operand __C to the CRC-32C checksum of operand __D.
