/**************************** 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 * * (c) Copyright 2012-2017 GNU General Public License www.gnu.org/licenses ******************************************************************************/ #ifndef VECTORCLASS_H #define VECTORCLASS_H 129 // Maximum vector size, bits.
