We require hardware support for AVX2 instructions. You have to make sure that you instruct your
compiler to use these instructions as needed. Under compilers such as GNU GCC or LLVM clang, the
flag `-march=native` used on a recent Intel compiler (Haswell or better) is sufficient. You may
also use the flags `-mavx2 -mbmi2`. Under Visual Studio, you need to target x64 and add the
flag `/arch:AVX2`.
Note: In some settings, it might be desirable to precompile `simdjson.cpp` instead of including it.
## Usage (old-school Makefile on platforms like Linux or macOS)
Requirements: recent clang or gcc, and make. We recommend at least GNU GCC/G++ 7 or LLVM clang 6. A system like Linux or macOS is expected.
