// Jief : I think __attribute__ ((used)) was needed for older version of GCC, can't remember.
//        If you want to put it back, do it only for the compiler version that really needs it.
//        Nov 2020 : With Gcc 10.2, defining it for memset is ok, but not needed. Defining it for memcpy generates an error in GenFW.
