 303         NULL.
 304         * interf.c(sim_load): Pass the whole string, not just the first
 305         byte.
 306
 307 Version 2.1 26-02-96
 308 --------------------
 309
 310 * Fixed bug in "go" command.
 311
 312 version 2.0 05-02-96
 313 --------------------
 314
 315 * Fixed bug in interrupt force register (erc32.c).
 316
 317 * Change file load function to use bfd_openr.
 318
 319 * SIS should now be endian independent.
 320
 321 version 1.8 24-11-95
 322 --------------------
 323
 324 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 325   the resource dependencies right.
 326
 327 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 328   but no FPU trap is generated.
 329
 330 version 1.7.1 31-10-95
 331 --------------------
 332
 333 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 334   the FPU stays in execute mode.
 335
 336 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 337
 338
 339 version 1.7 25-10-95
 340 --------------------
 341
 342 * Interrupt during annuled instruction corrupted return address - fixed.
 343
 344
 345 version 1.6.2 25-10-95
 346 --------------------
 347
 348 * Added -DFAST_UART to Makefile
 349
 350
 351 version 1.6.1 24-10-95
 352 --------------------
 353
 354 * Fixed bug in STDFQ which caused bus error
 355
 356
 357 version 1.6 02-10-95
 358 --------------------
 359
 360 * Modified srt0.s to include code that initiates registers in IU and FPU
 361   and initializes the data segment. The simulator 'load' command does not
 362   longer initialize the data segment!
 363
 364 * Corrected MEC timer operation; scalers now divide the frequency by
 365   (scaler_value + 1).
 366
 367 * MEC breakpoints are not checked during store operation
 368
 369
 370 version 1.5 14-09-95
 371 --------------------
 372
 373 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 374
 375 * Fixed bug that allowed an annuled instruction to cause memory exception.
 376
 377 * The *ws parameter in mem.c should now contain the number of waitstates
 378   required by the memory access (was total number of cycles).
 379
 380 * The supplied srt0.s now clears the BSS (thanks Joel).
 381
 382 version 1.4 22-08-95
 383 --------------------
 384
 385 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 386 some problems on solaris 2.x machines.
 387
 388 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 389 may suffer a bit ...
 390
 391 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 392
 393 version 1.3 26-07-95
 394 --------------------
 395
 396 * Fixed bug in mulscc instruction (how could that ever have worked?)
 397
 398 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 399
