  29    On the SPARC, we have a "no-overflow" mode which is used when an add or
  30    subtract insn is used to set the condition code.  Different branches are
  31    used in this case for some operations.
  32
  33    We also have two modes to indicate that the relevant condition code is
  34    in the floating-point condition code register.  One for comparisons which
  35    will generate an exception if the result is unordered (CCFPEmode) and
  36    one for comparisons which will never trap (CCFPmode).
  37
  38    CCXmode and CCX_NOOVmode are only used by v9.  */
