_mm_cmpestra int _mm_cmpestra(__m128i a, int la, __m128i b, int lb): So SSE4.2 has a lot of hard-to-understand instructions. Here is another explanation.
_mm_cmpestrc int _mm_cmpestrc(__m128i a, int la, __m128i b, int lb): Compare packed strings in a and b with lengths la and lb using the control in imm8, and returns 1 if the resulting mask was non-zero, and 0 otherwise.
_mm_cmpestri int _mm_cmpestri(__m128i a, int la, __m128i b, int lb): Compare packed strings in a and b with lengths la and lb using the control in imm8, and return the generated index. Note: if the mask is all zeroes, the returned index is always Count (8 or 16 depending on size).
_mm_cmpestrm __m128i _mm_cmpestrm(__m128i a, int la, __m128i b, int lb): Compare packed strings in a and b with lengths la and lb using the control in imm8, and return the generated mask.
_mm_cmpestro int _mm_cmpestro(__m128i a, int la, __m128i b, int lb): Compare packed strings in a and b with lengths la and lb using the control in imm8, and returns bit 0 of the resulting bit mask.
_mm_cmpestrs int _mm_cmpestrs(__m128i a, int la, __m128i b, int lb): Returns 1 if "any character in a was null", and 0 otherwise. Warning: what they mean is it returns 1 if the given length la is < Count.
_mm_cmpestrz int _mm_cmpestrz(__m128i a, int la, __m128i b, int lb): Returns 1 if "any character in b was null", and 0 otherwise. Warning: what they mean is it returns 1 if the given length lb is < Count.
_mm_cmpgt_epi64 __m128i _mm_cmpgt_epi64(__m128i a, __m128i b): Compare packed signed 64-bit integers in a and b for greater-than.
_mm_cmpistra int _mm_cmpistra(__m128i a, __m128i b): Compare packed strings with implicit lengths in a and b using the control in imm8, and returns 1 if b did not contain a null character and the resulting mask was zero, and 0 otherwise.
_mm_cmpistrc int _mm_cmpistrc(__m128i a, __m128i b): Compare packed strings with implicit lengths in a and b using the control in imm8, and returns 1 if the resulting mask was non-zero, and 0 otherwise.
_mm_cmpistri int _mm_cmpistri(__m128i a, __m128i b): Compare packed strings with implicit lengths in a and b using the control in imm8 and return the generated index. Note: if the mask is all zeroes, the returned index is always Count (8 or 16 depending on size).
_mm_cmpistrm __m128i _mm_cmpistrm(__m128i a, __m128i b): Compare packed strings with implicit lengths in a and b using the control in imm8, and return the generated mask.
_mm_cmpistro int _mm_cmpistro(__m128i a, __m128i b): Compare packed strings in a and b with lengths la and lb using the control in imm8, and returns bit 0 of the resulting bit mask.
_mm_cmpistrs int _mm_cmpistrs(__m128i a, __m128i b): Returns 1 if any character in a was null, and 0 otherwise.
_mm_cmpistrz int _mm_cmpistrz(__m128i a, __m128i b): Returns 1 if any character in b was null, and 0 otherwise.
_mm_crc32_u16 uint _mm_crc32_u16(uint crc, ushort v): Starting with the initial value in crc, accumulates a CR32 value for unsigned 16-bit integer v. Warning: this is computing CRC-32C (Castagnoli), not CRC-32.
_mm_crc32_u32 uint _mm_crc32_u32(uint crc, uint v): Starting with the initial value in crc, accumulates a CRC32 value for unsigned 32-bit integer v. Warning: this is computing CRC-32C (Castagnoli), not CRC-32.
_mm_crc32_u64 ulong _mm_crc32_u64(ulong crc, ulong v): Starting with the initial value in crc, accumulates a CRC32 value for unsigned 64-bit integer v. Warning: this is computing CRC-32C (Castagnoli), not CRC-32.
_mm_crc32_u8 uint _mm_crc32_u8(uint crc, ubyte v): Starting with the initial value in crc, accumulates a CRC32 value for unsigned 8-bit integer v. Warning: this is computing CRC-32C (Castagnoli), not CRC-32.

Variables

_SIDD_BIT_MASK enum int _SIDD_BIT_MASK;: **Mask only**: return the bit mask (default).
_SIDD_CMP_EQUAL_ANY enum int _SIDD_CMP_EQUAL_ANY;: For each character in b, find if it is in a (default) The resulting mask has bit set at b positions that were found in a.
_SIDD_CMP_EQUAL_EACH enum int _SIDD_CMP_EQUAL_EACH;: The strings defined by a and b are equal
_SIDD_CMP_EQUAL_ORDERED enum int _SIDD_CMP_EQUAL_ORDERED;: Search for the defined substring in the target
_SIDD_CMP_RANGES enum int _SIDD_CMP_RANGES;: For each character in b, determine if a[0] <= c <= a[1] or a[1] <= c <= a[2]... Contrarily to false documentation on the Internet, pairs must be in a!
_SIDD_LEAST_SIGNIFICANT enum int _SIDD_LEAST_SIGNIFICANT;: **Index only**: return the least significant bit (default).
_SIDD_MASKED_NEGATIVE_POLARITY enum int _SIDD_MASKED_NEGATIVE_POLARITY;: Negates results only before the end of the string
_SIDD_MASKED_POSITIVE_POLARITY enum int _SIDD_MASKED_POSITIVE_POLARITY;: No effect. Do not negate results before the end of the string. (default when using _SIDD_NEGATIVE_POLARITY) You basically never want this.
_SIDD_MOST_SIGNIFICANT enum int _SIDD_MOST_SIGNIFICANT;: **Index only**: return the most significant bit.
_SIDD_NEGATIVE_POLARITY enum int _SIDD_NEGATIVE_POLARITY;: Negates results
_SIDD_POSITIVE_POLARITY enum int _SIDD_POSITIVE_POLARITY;: Do not negate results (default, no effect)
_SIDD_SBYTE_OPS enum int _SIDD_SBYTE_OPS;: String contains signed 8-bit characters.
_SIDD_SWORD_OPS enum int _SIDD_SWORD_OPS;: String contains signed 16-bit characters.
_SIDD_UBYTE_OPS enum int _SIDD_UBYTE_OPS;: String contains unsigned 8-bit characters (default).
_SIDD_UNIT_MASK enum int _SIDD_UNIT_MASK;: **Mask only**: return the byte/word mask.
_SIDD_UWORD_OPS enum int _SIDD_UWORD_OPS;: String contains unsigned 16-bit characters.
