1591 * simops.c: Remove unused functions. Rough cut at
1592 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1594 * v850_sim.h (struct _state): Remove "psw" field. Add
1596 (PSW): Remove bogus definition.
1597 * simops.c: Change condition code handling to use the psw
1598 register within the sregs array. Handle "ldsr" and "stsr".
1600 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1602 * interp.c (do_format_5): Get operands correctly and
1603 call the target function.
1604 (sim_resume): Don't do a PC update for format 5 instructions.
1605 * simops.c: Handle "jarl" and "jmp" instructions.
1607 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1608 "di", and "ei" instructions correctly.
1610 * interp.c (do_format_3): Get operands correctly and call
1611 the target function.
1612 * simops.c: Handle bCC instructions.
1614 * simops.c: Add condition code handling to shift insns.
1615 Fix minor typos in condition code handling for other insns.
1617 * Makefile.in: Fix typo.
1618 * simops.c: Add condition code handling to "sub" "subr" and
1619 "divh" instructions.
1621 * interp.c (hash): Update to be more accurate.
1622 (lookup_hash): Call hash rather than computing the hash
1624 (do_format_1_2): Handle format 1 and format 2 instructions.
1625 Get operands correctly and call the target function.
1626 (do_format_6): Get operands correctly and call the target
1628 (do_formats_9_10): Rough cut so shift ops will work.
1629 (sim_resume): Tweak to deal with format 1 and format 2
1630 handling in a single funtion. Don't update the PC
1631 for format 3 insns. Fix typos.
1632 * simops.c: Slightly reorganize. Add condition code handling
1633 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1634 and "not" instructions.
1635 * v850_sim.h (reg_t): Registers are 32bits.
1636 (_state): The V850 has 32 general registers. Add a 32bit
1637 psw and pc register too. Add accessor macros
1639 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1640 changes from the d10v simulator.
1642 * simops.c: Add shift support.
1644 * simops.c: Add multiply & divide support. Abort for system
1647 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1648 and subr. No condition codes yet.

1652 * ChangeLog, Makefile.in, configure, configure.in, v850_sim.h,
1653 gencode.c, interp.c, simops.c: Created.
