1830 * simops.c: Handle "jarl" and "jmp" instructions.
1831
1832 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1833 "di", and "ei" instructions correctly.
1834
1835 * interp.c (do_format_3): Get operands correctly and call
1836 the target function.
1837 * simops.c: Handle bCC instructions.
1838
1839 * simops.c: Add condition code handling to shift insns.
1840 Fix minor typos in condition code handling for other insns.
1841
1842 * Makefile.in: Fix typo.
1843 * simops.c: Add condition code handling to "sub" "subr" and
1844 "divh" instructions.
1845
1846 * interp.c (hash): Update to be more accurate.
1847 (lookup_hash): Call hash rather than computing the hash
1848 code here.
1849 (do_format_1_2): Handle format 1 and format 2 instructions.
1850 Get operands correctly and call the target function.
1851 (do_format_6): Get operands correctly and call the target
1852 function.
1853 (do_formats_9_10): Rough cut so shift ops will work.
1854 (sim_resume): Tweak to deal with format 1 and format 2
1855 handling in a single funtion. Don't update the PC
1856 for format 3 insns. Fix typos.
1857 * simops.c: Slightly reorganize. Add condition code handling
1858 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1859 and "not" instructions.
1860 * v850_sim.h (reg_t): Registers are 32bits.
1861 (_state): The V850 has 32 general registers. Add a 32bit
1862 psw and pc register too. Add accessor macros
1863
1864 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1865 changes from the d10v simulator.
1866
1867 * simops.c: Add shift support.
1868
1869 * simops.c: Add multiply & divide support. Abort for system
1870 instructions.
1871
1872 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1873 and subr. No condition codes yet.
