Description :
A precise assigns clause for function memcpy is /@ assigns ((char)dst)[0..n] \from ((char*)src)[0..n]; assigns \result \from dst; / void Frama_C_memcpy(void* dst, const void* src, unsigned n);
This is currently not treated by the aforementioned Db function, probably because of the casts to char*. By using char* directly everywhere, the assigns clause is (imprecisely) translated to something equivalent to /*@ assigns dst[..] \from src[..];
Since the comment on the function is to complain if some unsupported cases are required, I'm complaining :-)
