Functions

_mm_cmpestrasse4.2

Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return 1 if b did not contain a null character and the resulting mask was zero, and 0 otherwise.

_mm_cmpestrcsse4.2

Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return 1 if the resulting mask was non-zero, and 0 otherwise.

_mm_cmpestrisse4.2

Compares packed strings a and b with lengths la and lb using the control in IMM8 and return the generated index. Similar to _mm_cmpistri with the exception that _mm_cmpistri implicitly determines the length of a and b.

_mm_cmpestrmsse4.2

Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return the generated mask.

_mm_cmpestrosse4.2

Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return bit 0 of the resulting bit mask.

_mm_cmpestrssse4.2

Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return 1 if any character in a was null, and 0 otherwise.

_mm_cmpestrzsse4.2

Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return 1 if any character in b was null, and 0 otherwise.

_mm_cmpgt_epi64sse4.2

Compares packed 64-bit integers in a and b for greater-than, return the results.

_mm_cmpistrasse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8, and return 1 if b did not contain a null character and the resulting mask was zero, and 0 otherwise.

_mm_cmpistrcsse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8, and return 1 if the resulting mask was non-zero, and 0 otherwise.

_mm_cmpistrisse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8 and return the generated index. Similar to _mm_cmpestri with the exception that _mm_cmpestri requires the lengths of a and b to be explicitly specified.

_mm_cmpistrmsse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8, and return the generated mask.

_mm_cmpistrosse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8, and return bit 0 of the resulting bit mask.

_mm_cmpistrssse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8, and returns 1 if any character in a was null, and 0 otherwise.

_mm_cmpistrzsse4.2

Compares packed strings with implicit lengths in a and b using the control in IMM8, and return 1 if any character in b was null. and 0 otherwise.

_mm_crc32_u8sse4.2

Starting with the initial value in crc, return the accumulated CRC32-C value for unsigned 8-bit integer v.

_mm_crc32_u16sse4.2

Starting with the initial value in crc, return the accumulated CRC32-C value for unsigned 16-bit integer v.

_mm_crc32_u32sse4.2

Starting with the initial value in crc, return the accumulated CRC32-C value for unsigned 32-bit integer v.
