/**************************** vectorclass.h ********************************
* Author: Agner Fog
* Date created: 2012-05-30
* Last modified: 2017-05-10
* Version: 1.29
* Project: vector classes
* Description:
* Header file defining vector classes as interface to intrinsic functions
* in x86 microprocessors with SSE2 and later instruction sets up to AVX512.
*
* Instructions:
* Use Gnu, Clang, Intel or Microsoft C++ compiler. Compile for the desired
* instruction set, which must be at least SSE2. Specify the supported
* instruction set by a command line define, e.g. __SSE4_1__ if the
* compiler does not automatically do so.
*
* Each vector object is represented internally in the CPU as a vector
* register with 128, 256 or 512 bits.
*
* This header file includes the appropriate header files depending on the
* supported instruction set
*
* For detailed instructions, see VectorClass.pdf
