/* This file contains the prototypes for the DFP arithmetic, conversion, and

 * support decimal floating point rounding control and exception support
 * whilst those in libgcc do not.  GCC will place these in the code in
 * soft-dfp in place of arithmetic, conversion, or comparison functions, e.g.
 *   _Decimal128 foo = bar + bat;
 * will be replaced with:
 *   _Decima128 = __dpd_addtd3(bar,bat);  */
