2212855Sgabeblack@google.com  sc_nbexterns.h -- External functions for both sc_signed and sc_unsigned
2312855Sgabeblack@google.com                    classes. These functions work on two parameters u and
2412855Sgabeblack@google.com                    v, and copy the result to the first parameter u. This
2512855Sgabeblack@google.com                    is also the reason that they are suffixed with _on_help.
2612855Sgabeblack@google.com
2712855Sgabeblack@google.com                    The vec_* functions are called through either these
2812855Sgabeblack@google.com                    functions or those in sc_nbfriends.cpp. The functions in
2912855Sgabeblack@google.com                    sc_nbfriends.cpp perform their work on two inputs u and v,
3012855Sgabeblack@google.com                    and return the result object.
