-### Note about building with avx512 by g++ v9 and v10
-
-There is a risk when compile with avx512 by g++ v9 and v10,
-as some `MMX Technology` instructions is used by g++ v9/v10 
-without clearing fpu state. 
-Check [issue 154](https://github.com/intel/x86-simd-sort/issues/154) 
-for more details.
-
-Adding `g++` option `-mno-mmx`, which disables `MMX Technology` instructions, is a possible workaround.
