 352         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
 353         and "not" instructions.
 354         * v850_sim.h (reg_t): Registers are 32bits.
 355         (_state): The V850 has 32 general registers.  Add a 32bit
 356         psw and pc register too.  Add accessor macros
 357
 358         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
 359         changes from the d10v simulator.
 360
 361         * simops.c: Add shift support.
 362
 363         * simops.c: Add multiply & divide support.  Abort for system
 364         instructions.
