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
