 232         NULL.
 233         * interf.c(sim_load): Pass the whole string, not just the first
 234         byte.
 235
 236 Version 2.1 26-02-96
 237 --------------------
 238
 239 * Fixed bug in "go" command.
 240
 241 version 2.0 05-02-96
 242 --------------------
 243
 244 * Fixed bug in interrupt force register (erc32.c).
 245
 246 * Change file load function to use bfd_openr.
 247
 248 * SIS should now be endian independent.
 249
 250 version 1.8 24-11-95
 251 --------------------
 252
 253 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 254   the resource dependencies right.
 255
 256 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 257   but no FPU trap is generated.
 258
 259 version 1.7.1 31-10-95
 260 --------------------
 261
 262 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 263   the FPU stays in execute mode.
 264
 265 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 266
 267
 268 version 1.7 25-10-95
 269 --------------------
 270
 271 * Interrupt during annuled instruction corrupted return address - fixed.
 272
 273
 274 version 1.6.2 25-10-95
 275 --------------------
 276
 277 * Added -DFAST_UART to Makefile
 278
 279
 280 version 1.6.1 24-10-95
 281 --------------------
 282
 283 * Fixed bug in STDFQ which caused bus error
 284
 285
 286 version 1.6 02-10-95
 287 --------------------
 288
 289 * Modified srt0.s to include code that initiates registers in IU and FPU
 290   and initializes the data segment. The simulator 'load' command does not
 291   longer initialize the data segment!
 292
 293 * Corrected MEC timer operation; scalers now divide the frequency by
 294   (scaler_value + 1).
 295
 296 * MEC breakpoints are not checked during store operation
 297
 298
 299 version 1.5 14-09-95
 300 --------------------
 301
 302 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 303
 304 * Fixed bug that allowed an annuled instruction to cause memory exception.
 305
 306 * The *ws parameter in mem.c should now contain the number of waitstates
 307   required by the memory access (was total number of cycles).
 308
 309 * The supplied srt0.s now clears the BSS (thanks Joel).
 310
 311 version 1.4 22-08-95
 312 --------------------
 313
 314 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 315 some problems on solaris 2.x machines.
 316
 317 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 318 may suffer a bit ...
 319
 320 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 321
 322 version 1.3 26-07-95
 323 --------------------
 324
 325 * Fixed bug in mulscc instruction (how could that ever have worked?)
 326
 327 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 328
 329 version 1.2 13-07-95
 330 --------------------
 331
 332 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 333 one interrupt pending)
 334
 335 * Fixed updating of condition codes during logical instructions (carry and
 336 overflow were not reset)
 337
 338 * Fixed bug in WRTBR (tt field was wrongly over-written)
 339
 340 version 1.1 07-07-95
 341 --------------------
 342
 343 * Fixed several bugs in the interrupt handler and callback routines.
 344 (reported by Paul Warren, Alsys)
