About 'cbench-x86'

This is a simple header file targeting evaluation of computation overhead between C code snippets.

It also contains some helper macros for implementing a benchmark easier, such as the CPU cache line alignment.

Supported environment

• AMD64 (x86-64); must be compiled with GCC/CLANG.
• i386(x86) and MSVC supports are in the plan.

Example code

Reference 'example_avx256rotl.c' source file.

It is an example code for the performance comparison of an AVX2 based 'bit-rotate-to-left' implementation to the traditional 'bit-rotate-to-left'.
