--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The code is in c-family/c-common:
/* Assume that Ox is -Ox, a numeric value is -Ox, a s by
itself is -Os, and any other switch begins with a -f. */
if ((*p >= '0' && *p <= '9')
|| (p[0] == 's' && p[1] == '\0'))
*r++ = 'O';
else if (*p != 'O')
*r++ = 'f';
as you can see 's' is support by that but 'g' or "fast" is not.
