◆ _mm_crc32_u16()

static __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
__CAn unsigned integer operand to add to the CRC-32C checksum of operand __D.
__DAn 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()

static __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
__CAn unsigned integer operand to add to the CRC-32C checksum of operand __D.
__DAn 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()

static __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
__CAn unsigned integer operand to add to the CRC-32C checksum of operand __D.
__DAn 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.
