5 * simops.c: Don't forget to initialize temp for
8 * interp.c: Remove various debugging printfs.
10 * simops.c: Fix satadd, satsub boundary case handling.
12 * interp.c (hash): Fix.
13 * interp.c (do_format_8): Get operands correctly and

19 * interp.c (do_format_4): Get operands correctly and
20 call the target function.
21 * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
24 * v850_sim.h: The V850 doesn't have split I&D spaces. Change
25 accordingly. Remove many unused definitions.
26 * interp.c: The V850 doesn't have split I&D spaces. Change
28 (get_longlong, get_longword, get_word): Deleted.
29 (write_longlong, write_longword, write_word): Deleted.
30 (get_operands): Deleted.
31 (get_byte, get_half, get_word): New functions.
32 (put_byte, put_half, put_word): New functions.
33 * simops.c: Remove unused functions. Rough cut at
34 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
36 * v850_sim.h (struct _state): Remove "psw" field. Add
38 (PSW): Remove bogus definition.
39 * simops.c: Change condition code handling to use the psw
40 register within the sregs array. Handle "ldsr" and "stsr".
42 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
44 * interp.c (do_format_5): Get operands correctly and
45 call the target function.
46 (sim_resume): Don't do a PC update for format 5 instructions.
47 * simops.c: Handle "jarl" and "jmp" instructions.
49 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
50 "di", and "ei" instructions correctly.
52 * interp.c (do_format_3): Get operands correctly and call
54 * simops.c: Handle bCC instructions.
56 * simops.c: Add condition code handling to shift insns.
57 Fix minor typos in condition code handling for other insns.
59 * Makefile.in: Fix typo.
60 * simops.c: Add condition code handling to "sub" "subr" and
63 * interp.c (hash): Update to be more accurate.
64 (lookup_hash): Call hash rather than computing the hash
66 (do_format_1_2): Handle format 1 and format 2 instructions.
67 Get operands correctly and call the target function.
68 (do_format_6): Get operands correctly and call the target
70 (do_formats_9_10): Rough cut so shift ops will work.
71 (sim_resume): Tweak to deal with format 1 and format 2
72 handling in a single funtion. Don't update the PC
73 for format 3 insns. Fix typos.
74 * simops.c: Slightly reorganize. Add condition code handling
75 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
76 and "not" instructions.
77 * v850_sim.h (reg_t): Registers are 32bits.
78 (_state): The V850 has 32 general registers. Add a 32bit
79 psw and pc register too. Add accessor macros
81 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
82 changes from the d10v simulator.
84 * simops.c: Add shift support.
86 * simops.c: Add multiply & divide support. Abort for system
89 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
90 and subr. No condition codes yet.

94 * ChangeLog, Makefile.in, configure, configure.in, v850_sim.h,
95 gencode.c, interp.c, simops.c: Created.
