* sim-bits.h (_MSB_16, _LSB_16): Define for 16-bit targets. (MASK, LSBIT, MSBIT): Likewise and use _MSB_16 and _LSB_16. (EXTENDED): Define for 16-bit word size. * sim-bits.c (LSEXTRACTED, MSEXTRACTED, LSINSERTED, MSINSERTED, LSSEXT, MSSEXT): Implement for 16-bit word size. * sim-types.h: Added support for 16-bit targets.
