1315 call the target function.
1316 * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
1317 "sst.h", and "sst.w".
1318
1319 * v850_sim.h: The V850 doesn't have split I&D spaces. Change
1320 accordingly. Remove many unused definitions.
1321 * interp.c: The V850 doesn't have split I&D spaces. Change
1322 accordingly.
1323 (get_longlong, get_longword, get_word): Deleted.
1324 (write_longlong, write_longword, write_word): Deleted.
1325 (get_operands): Deleted.
1326 (get_byte, get_half, get_word): New functions.
1327 (put_byte, put_half, put_word): New functions.
1328 * simops.c: Remove unused functions. Rough cut at
1329 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1330
1331 * v850_sim.h (struct _state): Remove "psw" field. Add
1332 "sregs" field.
1333 (PSW): Remove bogus definition.
1334 * simops.c: Change condition code handling to use the psw
1335 register within the sregs array. Handle "ldsr" and "stsr".
1336
1337 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1338
1339 * interp.c (do_format_5): Get operands correctly and
1340 call the target function.
1341 (sim_resume): Don't do a PC update for format 5 instructions.
1342 * simops.c: Handle "jarl" and "jmp" instructions.
1343
1344 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1345 "di", and "ei" instructions correctly.
1346
1347 * interp.c (do_format_3): Get operands correctly and call
1348 the target function.
1349 * simops.c: Handle bCC instructions.
1350
1351 * simops.c: Add condition code handling to shift insns.
1352 Fix minor typos in condition code handling for other insns.
1353
1354 * Makefile.in: Fix typo.
1355 * simops.c: Add condition code handling to "sub" "subr" and
1356 "divh" instructions.
1357
1358 * interp.c (hash): Update to be more accurate.
1359 (lookup_hash): Call hash rather than computing the hash
1360 code here.
1361 (do_format_1_2): Handle format 1 and format 2 instructions.
1362 Get operands correctly and call the target function.
1363 (do_format_6): Get operands correctly and call the target
1364 function.
1365 (do_formats_9_10): Rough cut so shift ops will work.
1366 (sim_resume): Tweak to deal with format 1 and format 2
1367 handling in a single funtion. Don't update the PC
1368 for format 3 insns. Fix typos.
1369 * simops.c: Slightly reorganize. Add condition code handling
1370 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1371 and "not" instructions.
1372 * v850_sim.h (reg_t): Registers are 32bits.
1373 (_state): The V850 has 32 general registers. Add a 32bit
1374 psw and pc register too. Add accessor macros
1375
1376 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1377 changes from the d10v simulator.
1378
1379 * simops.c: Add shift support.
1380
1381 * simops.c: Add multiply & divide support. Abort for system
1382 instructions.
1383
1384 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1385 and subr. No condition codes yet.
