[Patch: RL78] Add support for 64-bit doubles

[DJ Delorie]

I think this part is wrong (and your mailer is dropping some
whitespace).  "long double" should always be 64 bits, which means that
libgcc must always have DFmode helpers.


 #define LONG_DOUBLE_TYPE_SIZE64 /*DOUBLE_TYPE_SIZE*/

-#define LIBGCC2_HAS_DF_MODE1
+#ifdef __RL78_32BIT_DOUBLES__
+#define LIBGCC2_HAS_DF_MODE             0
+#define LIBGCC2_LONG_DOUBLE_TYPE_SIZE   32
+#else
+#define LIBGCC2_HAS_DF_MODE             1
 #define LIBGCC2_LONG_DOUBLE_TYPE_SIZE   64
+#endif
