Intel® C++ Compiler 16.0 User and Reference Guide
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 .
These intrinsics are used for compilation and do not generate any instructions.
