1825         (sim_resume): Don't do a PC update for format 5 instructions.
1826         * simops.c: Handle "jarl" and "jmp" instructions.
1827
1828         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
1829         "di", and "ei" instructions correctly.
1830
1831         * interp.c (do_format_3): Get operands correctly and call
1832         the target function.
1833         * simops.c: Handle bCC instructions.
1834
1835         * simops.c: Add condition code handling to shift insns.
1836         Fix minor typos in condition code handling for other insns.
1837
1838         * Makefile.in: Fix typo.
1839         * simops.c: Add condition code handling to "sub" "subr" and
1840         "divh" instructions.
1841
1842         * interp.c (hash): Update to be more accurate.
1843         (lookup_hash): Call hash rather than computing the hash
1844         code here.
1845         (do_format_1_2): Handle format 1 and format 2 instructions.
1846         Get operands correctly and call the target function.
1847         (do_format_6): Get operands correctly and call the target
1848         function.
1849         (do_formats_9_10): Rough cut so shift ops will work.
1850         (sim_resume): Tweak to deal with format 1 and format 2
1851         handling in a single funtion.  Don't update the PC
1852         for format 3 insns.  Fix typos.
1853         * simops.c: Slightly reorganize.  Add condition code handling
1854         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1855         and "not" instructions.
1856         * v850_sim.h (reg_t): Registers are 32bits.
1857         (_state): The V850 has 32 general registers.  Add a 32bit
1858         psw and pc register too.  Add accessor macros
1859
1860         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1861         changes from the d10v simulator.
1862
1863         * simops.c: Add shift support.
1864
1865         * simops.c: Add multiply & divide support.  Abort for system
1866         instructions.
1867
1868         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1869         and subr.  No condition codes yet.
