Intrinsics for Integer Subtraction Operations

The prototypes for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) intrinsics are located in the zmmintrin.h header file. For purposes of including a header in your code, use immintrin.h .

Intrinsic Name	Operation	Corresponding Intel® AVX-512 Instruction
`_mm512_sub_epi32`, `_mm512_mask_sub_epi32`, `_mm512_maskz_sub_epi32`	Subtracts int32 elements.	`VPSUBD`
`_mm512_sub_epi64`, `_mm512_mask_sub_epi64`, `_mm512_maskz_sub_epi64`	Subtracts int64 elements.	`VPSUBQ`

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_sub_epi32

extern __m512i __cdecl _mm512_sub_epi32(__m512i a, __m512i b);

Subtracts packed 32-bit integers in b from packed 32-bit integers in a, and stores the result.

_mm512_mask_sub_epi32

extern __m512i __cdecl _mm512_mask_sub_epi32(__m512i src, __mmask16 k, __m512i a, __m512i b);

Subtracts packed 32-bit integers in b from packed 32-bit integers in a, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).

_mm512_maskz_sub_epi32

extern __m512i __cdecl _mm512_maskz_sub_epi32(__mmask16 k, __m512i a, __m512i b);

Subtracts packed 32-bit integers in b from packed 32-bit integers in a, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).

_mm512_sub_epi64

extern __m512i __cdecl _mm512_sub_epi64(__m512i a, __m512i b);

Subtracts packed 64-bit integers in b from packed 64-bit integers in a, and stores the result.

_mm512_mask_sub_epi64

extern __m512i __cdecl _mm512_mask_sub_epi64(__m512i src, __mmask8 k, __m512i a, __m512i b);

Subtracts packed 64-bit integers in b from packed 64-bit integers in a, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).

_mm512_maskz_sub_epi64

extern __m512i __cdecl _mm512_maskz_sub_epi64(__mmask8 k, __m512i a, __m512i b);

Subtracts packed 64-bit integers in b from packed 64-bit integers in a, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
