/* FIXME: defining add_ssaaaa and sub_ddmmss should be advantageous for
DFmode ("double" intrinsics, avoiding two of the three insns handling
carry), but defining them as open-code C composing and doing the
operation in DImode (UDImode) shows that the DImode needs work:
register pressure from requiring neighboring registers and the
traffic to and from them come to dominate, in the 4.7 series. */
