Intrinsics for Test Operations

The prototypes for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) intrinsics are located in the
zmmintrin.h
header file.
To use these intrinsics, include the
immintrin.h
file as follows:
#include <immintrin.h>

variable
definition
k
writemask used as a selector
a
first source vector element
b
second source vector element
src
source element to use based on writemask result
_mm512_conflict_epi32
extern __m512i __cdecl _mm512_conflict_epi32(__m512i a);
Tests each 32-bit element of
a
for equality with all other elements in
a
closer to the least significant bit.
Each element's comparison forms a zero extended bit vector in the destination.
_mm512_mask_conflict_epi32
extern __m512i __cdecl _mm512_mask_conflict_epi32(__m512i src, __mmask16 k, __m512i a);
Tests each 32-bit element of
a
for equality with all other elements in
a
closer to the least significant bit using writemask
k
(elements are copied from
src
when the corresponding mask bit is not set).
Each element's comparison forms a zero extended bit vector in the destination.
_mm512_maskz_conflict_epi32
extern __m512i __cdecl _mm512_maskz_conflict_epi32(__mmask16 k, __m512i a);
Tests each 32-bit element of
a
for equality with other elements in
a
closer to the least significant bit using zeromask
k
(elements are zeroed out when the corresponding mask bit is not set).
Each element's comparison forms a zero extended bit vector in the destination.
_mm512_conflict_epi64
extern __m512i __cdecl _mm512_conflict_epi64(__m512i a);
Tests each 64-bit element of
a
for equality with other elements in
a
closer to the least significant bit.
Each element's comparison forms a zero extended bit vector in the destination.
_mm512_mask_conflict_epi64
extern __m512i __cdecl _mm512_mask_conflict_epi64(__m512i src, __mmask8 k, __m512i a);
Tests each 64-bit element of
a
for equality with other elements in
a
closer to the least significant bit using writemask
k
(elements are copied from
src
when the corresponding mask bit is not set).
Each element's comparison forms a zero extended bit vector in the destination.
_mm512_maskz_conflict_epi64
extern __m512i __cdecl _mm512_maskz_conflict_epi64(__mmask8 k, __m512i a);
Tests each 64-bit element of
a
for equality with other elements in
a
closer to the least significant bit using zeromask
k
(elements are zeroed out when the corresponding mask bit is not set).
Each element's comparison forms a zero extended bit vector the destination.
_mm512_test_epi32_mask
extern __mmask16 __cdecl _mm512_test_epi32_mask(__m512i a, __m512i b);
Computes the bitwise
AND
of packed 32-bit integers in
a
and
b
, producing intermediate 32-bit values, and sets the corresponding bit in result mask
k
if the intermediate value is non-zero.
_mm512_mask_test_epi32_mask
extern __mmask16 __cdecl _mm512_mask_test_epi32_mask(__mmask16 k, __m512i a, __m512i b);
Computes the bitwise
AND
of packed 32-bit integers in
a
and
b
, producing intermediate 32-bit values, and sets the corresponding bit in result mask
k
(subject to writemask
k
) if the intermediate value is non-zero.
