1313 (get_operands): Deleted.
1314 (get_byte, get_half, get_word): New functions.
1315 (put_byte, put_half, put_word): New functions.
1316 * simops.c: Remove unused functions. Rough cut at
1317 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1318
1319 * v850_sim.h (struct _state): Remove "psw" field. Add
1320 "sregs" field.
1321 (PSW): Remove bogus definition.
1322 * simops.c: Change condition code handling to use the psw
1323 register within the sregs array. Handle "ldsr" and "stsr".
1324
1325 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1326
1327 * interp.c (do_format_5): Get operands correctly and
1328 call the target function.
1329 (sim_resume): Don't do a PC update for format 5 instructions.
1330 * simops.c: Handle "jarl" and "jmp" instructions.
1331
1332 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1333 "di", and "ei" instructions correctly.
1334
1335 * interp.c (do_format_3): Get operands correctly and call
1336 the target function.
1337 * simops.c: Handle bCC instructions.
1338
1339 * simops.c: Add condition code handling to shift insns.
1340 Fix minor typos in condition code handling for other insns.
1341
1342 * Makefile.in: Fix typo.
1343 * simops.c: Add condition code handling to "sub" "subr" and
1344 "divh" instructions.
1345
1346 * interp.c (hash): Update to be more accurate.
1347 (lookup_hash): Call hash rather than computing the hash
1348 code here.
1349 (do_format_1_2): Handle format 1 and format 2 instructions.
1350 Get operands correctly and call the target function.
1351 (do_format_6): Get operands correctly and call the target
1352 function.
1353 (do_formats_9_10): Rough cut so shift ops will work.
1354 (sim_resume): Tweak to deal with format 1 and format 2
1355 handling in a single funtion. Don't update the PC
1356 for format 3 insns. Fix typos.
1357 * simops.c: Slightly reorganize. Add condition code handling
1358 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1359 and "not" instructions.
1360 * v850_sim.h (reg_t): Registers are 32bits.
1361 (_state): The V850 has 32 general registers. Add a 32bit
1362 psw and pc register too. Add accessor macros
1363
1364 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1365 changes from the d10v simulator.
1366
1367 * simops.c: Add shift support.
1368
1369 * simops.c: Add multiply & divide support. Abort for system
1370 instructions.
1371
1372 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1373 and subr. No condition codes yet.
