Module `sse42`

Streaming SIMD Extensions 4.2 (SSE4.2)

Extends SSE4.1 with STTNI (String and Text New Instructions).

Functions

_mm_cmpestra 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_cmpestrc 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_cmpestri 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_cmpestrm Compares packed strings in a and b with lengths la and lb using the control in IMM8, and return the generated mask.
_mm_cmpestro 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_cmpestrs 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_cmpestrz 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_epi64 Compares packed 64-bit integers in a and b for greater-than, return the results.
_mm_cmpistra 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_cmpistrc 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_cmpistri 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_cmpistrm Compares packed strings with implicit lengths in a and b using the control in IMM8, and return the generated mask.
_mm_cmpistro 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_cmpistrs 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_cmpistrz 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_u16 Starting with the initial value in crc, return the accumulated CRC32-C value for unsigned 16-bit integer v.
_mm_crc32_u32 Starting with the initial value in crc, return the accumulated CRC32-C value for unsigned 32-bit integer v.
_mm_crc32_u8 Starting with the initial value in crc, return the accumulated CRC32-C value for unsigned 8-bit integer v.

Constants

_SIDD_BIT_MASK Mask only: return the bit mask
_SIDD_CMP_EQUAL_ANY For each character in a, find if it is in b (Default)
_SIDD_CMP_EQUAL_EACH The strings defined by a and b are equal
