The FMV (4.8) and clone (6.0) features are intended to be easier-to-use wrappers around ifunc. FMV-4.8 (C++) generates the ifunc dispatching code for the programmer, and FMV-6.0 (C/C++) moves on to do the code duplication for the programmer too. It is added with the assumption that GCC's optimization / vectorization magic is good enough to gain significant performance gains by just changing -march options on the exact same piece of code.
