   8  * It seems as though gcc expects its implicit arithmetic functions to
   9  * be cdecl, even if -mrtd is specified.  This is somewhat
  10  * inconsistent; for example, if -mregparm=3 is used then the implicit
  11  * functions do become regparm(3).
  12  *
  13  * The implicit calls to memcpy() and memset() which gcc can generate
  14  * do not seem to have this inconsistency; -mregparm and -mrtd affect
  15  * them in the same way as any other function.
