What is wrong with optimization of code, e.g. replacing call to
memset by a quick loop which does same thing even faster than a
function call? ... beside that such optimization needs normally a
bit more of space it is faster and does same thing as original
function call. Try using size optimization (-Os) to avoid
replacing function calls by inline replacements.
