It only says the function has malloc behavior in that it returns a pointer that
does not alias with any other memory.  So

/* Nonzero if this is a call to malloc or a related function.  */
#define ECF_MALLOC              4

is not really useful documentation ;)  flags_from_decl_or_type has the slightly
more informative

     /* The function exp may have the `malloc' attribute.  */
     if (DECL_IS_MALLOC (exp))
       flags |= ECF_MALLOC;
