 258         * interf.c(sim_load): Pass the whole string, not just the first
 259         byte.
 260
 261 Version 2.1 26-02-96
 262 --------------------
 263
 264 * Fixed bug in "go" command.
 265
 266 version 2.0 05-02-96
 267 --------------------
 268
 269 * Fixed bug in interrupt force register (erc32.c).
 270
 271 * Change file load function to use bfd_openr.
 272
 273 * SIS should now be endian independent.
 274
 275 version 1.8 24-11-95
 276 --------------------
 277
 278 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 279   the resource dependencies right.
 280
 281 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 282   but no FPU trap is generated.
 283
 284 version 1.7.1 31-10-95
 285 --------------------
 286
 287 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 288   the FPU stays in execute mode.
 289
 290 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 291
 292
 293 version 1.7 25-10-95
 294 --------------------
 295
 296 * Interrupt during annuled instruction corrupted return address - fixed.
 297
 298
 299 version 1.6.2 25-10-95
 300 --------------------
 301
 302 * Added -DFAST_UART to Makefile
 303
 304
 305 version 1.6.1 24-10-95
 306 --------------------
 307
 308 * Fixed bug in STDFQ which caused bus error
 309
 310
 311 version 1.6 02-10-95
 312 --------------------
 313
 314 * Modified srt0.s to include code that initiates registers in IU and FPU
 315   and initializes the data segment. The simulator 'load' command does not
 316   longer initialize the data segment!
 317
 318 * Corrected MEC timer operation; scalers now divide the frequency by
 319   (scaler_value + 1).
 320
 321 * MEC breakpoints are not checked during store operation
 322
 323
 324 version 1.5 14-09-95
 325 --------------------
 326
 327 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 328
 329 * Fixed bug that allowed an annuled instruction to cause memory exception.
 330
 331 * The *ws parameter in mem.c should now contain the number of waitstates
 332   required by the memory access (was total number of cycles).
 333
 334 * The supplied srt0.s now clears the BSS (thanks Joel).
 335
 336 version 1.4 22-08-95
 337 --------------------
 338
 339 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 340 some problems on solaris 2.x machines.
 341
 342 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 343 may suffer a bit ...
 344
 345 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 346
 347 version 1.3 26-07-95
 348 --------------------
 349
 350 * Fixed bug in mulscc instruction (how could that ever have worked?)
 351
 352 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 353
 354 version 1.2 13-07-95
 355 --------------------
 356
 357 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 358 one interrupt pending)
 359
 360 * Fixed updating of condition codes during logical instructions (carry and
 361 overflow were not reset)
 362
 363 * Fixed bug in WRTBR (tt field was wrongly over-written)
 364
 365 version 1.1 07-07-95
 366 --------------------
 367
 368 * Fixed several bugs in the interrupt handler and callback routines.
 369 (reported by Paul Warren, Alsys)
