[PATCH] Force DFP function args into FP registers per the ABI

[David Edelsohn]

	The patch generally looks okay.  Too bad these new modes need to
diffuse into everything.

+	  /* Must use an even/odd register pair.  */

Would you please clarify this with "Decimal Float must..." or "_Decimal128
must..."  in both places?

+    case DDmode:
     case DFmode:
     case SFmode:
       if (CONSTANT_P (operands[1])

Please list DDmode after DFmode, so the ordering is consistent
everywhere.  When browsing these functions for modes, it's confusing to
have the decimal modes jump around.

The file is being added to the FSF in 2007, so the copyright should list

Okay with those changes.

Thanks, David
