403 | ||
404 | * simops.c: "rts" adds 4 to the stack pointer. | |
405 | ||
406 | * simops.c: Fix CF and CX computation for add instructions. | |
407 | ||
408 | * simops.c: Leave the upper 8 bits alone for logical ops. | |
409 | Mask off high 8 bits before doing any shifts/rotates. | |
410 | Fix carry bit handling in rotates again. | |

412 | Mon Jan 20 10:45:08 1997 Jeffrey A Law (law@cygnus.com) | |
413 | ||
414 | * simops.c: Don't lose the sign bit for "asr". | |

416 | Fri Jan 17 01:45:14 1997 Jeffrey A Law (law@cygnus.com) | |
417 | ||
418 | * simops.c: Fix overflow computation for "cmp" and "sub" | |
419 | instructions. | |
420 | ||
421 | * simops.c: Use the right register for "jmp (an)" and "jsr (an)". | |
422 | ||
423 | * interp.c (hash): Improve hashing for 3 byte instructions. | |
424 | ||
425 | * simops.c: Fix extraction of 16/24bit immediates for some | |
426 | instructions. "cmp" instructions only modify the PSW. | |
427 | Fix various thinkos when extracting register operands too. | |

430 | ||
431 | * simops.c: Fix "rol" and "ror". | |
432 | ||
433 | * simops.c: Truncate PC to 24bits after modifying it. | |
434 | Closer stab at emulated system calls. | |
435 | ||

437 | ||
438 | * interp.c (hash): Improve hashing of two byte insns. | |
439 | (store_mem): Handle storing 3 byte quantities. | |
440 | ||
441 | * simops.c: Fix various typos/thinkos. | |
442 | ||
443 | * interp.c (load_mem_big, load_mem, store_mem): Fix thinko in | |
444 | code to handle 24bit addresses. | |
445 | * simops.c (REG0_8, REG0_16): Fix typo. | |

448 | ||
449 | * mn10200_sim.h: Various fixes for mixed 16/24bit architecture. | |
450 | * interp.c: Similarly. | |
451 | * simops.c: Similarly. | |
452 | ||
453 | * Makefile.in, config.in, configure, configure.in: New files. | |
454 | * gencode.c, interp.c, mn10200_sim.h, simops.c: New files. | |
