 236         NULL.
 237         * interf.c(sim_load): Pass the whole string, not just the first
 238         byte.
 239
 240 Version 2.1 26-02-96
 241 --------------------
 242
 243 * Fixed bug in "go" command.
 244
 245 version 2.0 05-02-96
 246 --------------------
 247
 248 * Fixed bug in interrupt force register (erc32.c).
 249
 250 * Change file load function to use bfd_openr.
 251
 252 * SIS should now be endian independent.
 253
 254 version 1.8 24-11-95
 255 --------------------
 256
 257 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 258   the resource dependencies right.
 259
 260 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 261   but no FPU trap is generated.
 262
 263 version 1.7.1 31-10-95
 264 --------------------
 265
 266 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 267   the FPU stays in execute mode.
 268
 269 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 270
 271
 272 version 1.7 25-10-95
 273 --------------------
 274
 275 * Interrupt during annuled instruction corrupted return address - fixed.
 276
 277
 278 version 1.6.2 25-10-95
 279 --------------------
 280
 281 * Added -DFAST_UART to Makefile
 282
 283
 284 version 1.6.1 24-10-95
 285 --------------------
 286
 287 * Fixed bug in STDFQ which caused bus error
 288
 289
 290 version 1.6 02-10-95
 291 --------------------
 292
 293 * Modified srt0.s to include code that initiates registers in IU and FPU
 294   and initializes the data segment. The simulator 'load' command does not
 295   longer initialize the data segment!
 296
 297 * Corrected MEC timer operation; scalers now divide the frequency by
 298   (scaler_value + 1).
 299
 300 * MEC breakpoints are not checked during store operation
 301
 302
 303 version 1.5 14-09-95
 304 --------------------
 305
 306 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 307
 308 * Fixed bug that allowed an annuled instruction to cause memory exception.
 309
 310 * The *ws parameter in mem.c should now contain the number of waitstates
 311   required by the memory access (was total number of cycles).
 312
 313 * The supplied srt0.s now clears the BSS (thanks Joel).
 314
 315 version 1.4 22-08-95
 316 --------------------
 317
 318 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 319 some problems on solaris 2.x machines.
 320
 321 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 322 may suffer a bit ...
 323
 324 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 325
 326 version 1.3 26-07-95
 327 --------------------
 328
 329 * Fixed bug in mulscc instruction (how could that ever have worked?)
 330
 331 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 332
 333 version 1.2 13-07-95
 334 --------------------
 335
 336 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 337 one interrupt pending)
 338
 339 * Fixed updating of condition codes during logical instructions (carry and
 340 overflow were not reset)
 341
 342 * Fixed bug in WRTBR (tt field was wrongly over-written)
 343
 344 version 1.1 07-07-95
 345 --------------------
 346
 347 * Fixed several bugs in the interrupt handler and callback routines.
 348 (reported by Paul Warren, Alsys)
