描述

I just built caffe2 on Ubuntu 16.04.3 on Power8 LE, using all defaults except disabling NNPACK in the top CMakeLists.txt. It builds and installs fine, but when running "make test" it fails on the cpuid_test.

I hope MMX isn't really a requirement for caffe2.. ?

All other tests are successful.

研究方向
Investigate the cpuid test source file to determine why it fails on Power8. The issue is likely due to x86 specific cpuid instruction usage. Consider adding architecture detection or conditional compilation to skip the test on non x86 platforms. Reference the CMake configuration for platform specific settings.
