1821         * interp.c (do_format_3): Get operands correctly and call
1822         the target function.
1823         * simops.c: Handle bCC instructions.
1824
1825         * simops.c: Add condition code handling to shift insns.
1826         Fix minor typos in condition code handling for other insns.
1827
1828         * Makefile.in: Fix typo.
1829         * simops.c: Add condition code handling to "sub" "subr" and
1830         "divh" instructions.
1831
1832         * interp.c (hash): Update to be more accurate.
1833         (lookup_hash): Call hash rather than computing the hash
1834         code here.
1835         (do_format_1_2): Handle format 1 and format 2 instructions.
1836         Get operands correctly and call the target function.
1837         (do_format_6): Get operands correctly and call the target
1838         function.
1839         (do_formats_9_10): Rough cut so shift ops will work.
1840         (sim_resume): Tweak to deal with format 1 and format 2
1841         handling in a single funtion.  Don't update the PC
1842         for format 3 insns.  Fix typos.
1843         * simops.c: Slightly reorganize.  Add condition code handling
1844         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1845         and "not" instructions.
1846         * v850_sim.h (reg_t): Registers are 32bits.
1847         (_state): The V850 has 32 general registers.  Add a 32bit
1848         psw and pc register too.  Add accessor macros
1849
1850         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1851         changes from the d10v simulator.
1852
1853         * simops.c: Add shift support.
1854
1855         * simops.c: Add multiply & divide support.  Abort for system
1856         instructions.
1857
1858         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1859         and subr.  No condition codes yet.
