 360
 361 version 2.0 05-02-96
 362 --------------------
 363
 364 * Fixed bug in interrupt force register (erc32.c).
 365
 366 * Change file load function to use bfd_openr.
 367
 368 * SIS should now be endian independent.
 369
 370 version 1.8 24-11-95
 371 --------------------
 372
 373 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 374   the resource dependencies right.
 375
 376 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 377   but no FPU trap is generated.
 378
 379 version 1.7.1 31-10-95
 380 --------------------
 381
 382 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 383   the FPU stays in execute mode.
 384
 385 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 386
 387
 388 version 1.7 25-10-95
 389 --------------------
 390
 391 * Interrupt during annuled instruction corrupted return address - fixed.
 392
 393
 394 version 1.6.2 25-10-95
 395 --------------------
 396
 397 * Added -DFAST_UART to Makefile
 398
 399
 400 version 1.6.1 24-10-95
 401 --------------------
 402
 403 * Fixed bug in STDFQ which caused bus error
 404
 405
 406 version 1.6 02-10-95
 407 --------------------
 408
 409 * Modified srt0.s to include code that initiates registers in IU and FPU
 410   and initializes the data segment. The simulator 'load' command does not
 411   longer initialize the data segment!
 412
 413 * Corrected MEC timer operation; scalers now divide the frequency by
 414   (scaler_value + 1).
 415
 416 * MEC breakpoints are not checked during store operation
 417
 418
 419 version 1.5 14-09-95
 420 --------------------
 421
 422 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 423
 424 * Fixed bug that allowed an annuled instruction to cause memory exception.
 425
 426 * The *ws parameter in mem.c should now contain the number of waitstates
 427   required by the memory access (was total number of cycles).
 428
 429 * The supplied srt0.s now clears the BSS (thanks Joel).
 430
 431 version 1.4 22-08-95
 432 --------------------
 433
 434 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 435 some problems on solaris 2.x machines.
 436
 437 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 438 may suffer a bit ...
 439
 440 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 441
 442 version 1.3 26-07-95
 443 --------------------
 444
 445 * Fixed bug in mulscc instruction (how could that ever have worked?)
 446
 447 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 448
 449 version 1.2 13-07-95
 450 --------------------
 451
 452 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 453 one interrupt pending)
 454
 455 * Fixed updating of condition codes during logical instructions (carry and
 456 overflow were not reset)
 457
 458 * Fixed bug in WRTBR (tt field was wrongly over-written)
 459
 460 version 1.1 07-07-95
 461 --------------------
 462
 463 * Fixed several bugs in the interrupt handler and callback routines.
