 Overview

 The simdjson library takes advantage of SIMD instruction sets such as NEON, SSE and AVX to achieve
 much of its speed. Because these instruction sets work differently, simdjson has to compile a
 different version of the JSON parser for different CPU architectures, often with different
 algorithms to take better advantage of a given CPU!

 The current implementations are:

 * arm64: 64-bit ARMv8-A NEON

 In many cases, you don't know where your compiled binary is going to run, so simdjson automatically
 compiles *all* the implementations into the executable. On Intel, it will include 4 implementations
-(icelake, haswell, westmere and fallback), on ARM it will include 2 (arm64 and fallback), and on PPC

 Recent versions of Microsoft Visual Studio on Windows provides support for the LLVM Clang compiler. You  only need to install the "Clang compiler" optional component (ClangCL). You may also get a copy of the 64-bit LLVM CLang compiler for [Windows directly from LLVM](https://releases.llvm.org/download.html). The simdjson library fully supports the LLVM Clang compiler under Windows. In fact, you may get better performance out of simdjson with the LLVM Clang compiler than with the regular Visual Studio compiler. Meanwhile the [LLVM CLang compiler is binary compatible with Visual Studio](https://clang.llvm.org/docs/MSVCCompatibility.html) which means that you can combine their binaries (executables and libraries).
