How about this?

typedef unsigned int uint;
inline void foo0(uint k, uint n, double const& m, double* s, uint const*
c, double const* v) { #pragma ivdep
while (++k < n) s[ c[k] ] -= m * v[k]; }

template <class Ts, class Tc, class Tv>
inline void foo(uint k, uint n, double const& m, Ts s, Tc c, Tv v)
{ foo0(k, n, m, s, c, v); }
