# Intrinsics for Integer Addition 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>

Intrinsic Name | Operation | Corresponding Intel® AVX-512 Instruction
--- | --- | ---
`_mm512_add_epi32`, `_mm512_mask_add_epi32`, `_mm512_maskz_add_epi32` | Add int32 vectors. | `VPADDD`
`_mm512_add_epi64`, `_mm512_mask_add_epi64`, `_mm512_maskz_add_epi64` | Add int64 vectors. | `VPADDQ`

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_add_epi32

    extern __m512i __cdecl _mm512_add_epi32(__m512i a, __m512i b);

Adds packed int32 elements in a and b, and stores the result.

_mm512_mask_add_epi32

    extern __m512i __cdecl _mm512_mask_add_epi32(__m512i src, __mmask16 k, __m512i a, __m512i b);

Adds packed int32 elements in a and b, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).

_mm512_maskz_add_epi32

    extern __m512i __cdecl _mm512_maskz_add_epi32(__mmask16 k, __m512i a, __m512i b);

Adds packed int32 elements in a and b, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).

_mm512_add_epi64

    extern __m512i __cdecl _mm512_add_epi64(__m512i a, __m512i b);

Adds packed int64 elements in a and b, and stores the result.

_mm512_mask_add_epi64

    extern __m512i __cdecl _mm512_mask_add_epi64(__m512i src, __mmask8 k, __m512i a, __m512i b);

Adds packed int64 elements in a and b, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).

_mm512_maskz_add_epi64

    extern __m512i __cdecl _mm512_maskz_add_epi64(__mmask8 k, __m512i a, __m512i b);

Adds packed int64 elements in a and b, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
