 220         NULL.
 221         * interf.c(sim_load): Pass the whole string, not just the first
 222         byte.
 223
 224 Version 2.1 26-02-96
 225 --------------------
 226
 227 * Fixed bug in "go" command.
 228
 229 version 2.0 05-02-96
 230 --------------------
 231
 232 * Fixed bug in interrupt force register (erc32.c).
 233
 234 * Change file load function to use bfd_openr.
 235
 236 * SIS should now be endian independent.
 237
 238 version 1.8 24-11-95
 239 --------------------
 240
 241 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 242   the resource dependencies right.
 243
 244 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 245   but no FPU trap is generated.
 246
 247 version 1.7.1 31-10-95
 248 --------------------
 249
 250 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 251   the FPU stays in execute mode.
 252
 253 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 254
 255
 256 version 1.7 25-10-95
 257 --------------------
 258
 259 * Interrupt during annuled instruction corrupted return address - fixed.
 260
 261
 262 version 1.6.2 25-10-95
 263 --------------------
 264
 265 * Added -DFAST_UART to Makefile
 266
 267
 268 version 1.6.1 24-10-95
 269 --------------------
 270
 271 * Fixed bug in STDFQ which caused bus error
 272
 273
 274 version 1.6 02-10-95
 275 --------------------
 276
 277 * Modified srt0.s to include code that initiates registers in IU and FPU
 278   and initializes the data segment. The simulator 'load' command does not
 279   longer initialize the data segment!
 280
 281 * Corrected MEC timer operation; scalers now divide the frequency by
 282   (scaler_value + 1).
 283
 284 * MEC breakpoints are not checked during store operation
 285
 286
 287 version 1.5 14-09-95
 288 --------------------
 289
 290 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 291
 292 * Fixed bug that allowed an annuled instruction to cause memory exception.
 293
 294 * The *ws parameter in mem.c should now contain the number of waitstates
 295   required by the memory access (was total number of cycles).
 296
 297 * The supplied srt0.s now clears the BSS (thanks Joel).
 298
 299 version 1.4 22-08-95
 300 --------------------
 301
 302 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 303 some problems on solaris 2.x machines.
 304
 305 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 306 may suffer a bit ...
 307
 308 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 309
 310 version 1.3 26-07-95
 311 --------------------
 312
 313 * Fixed bug in mulscc instruction (how could that ever have worked?)
 314
 315 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 316
 317 version 1.2 13-07-95
 318 --------------------
 319
 320 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 321 one interrupt pending)
 322
 323 * Fixed updating of condition codes during logical instructions (carry and
 324 overflow were not reset)
 325
 326 * Fixed bug in WRTBR (tt field was wrongly over-written)
 327
 328 version 1.1 07-07-95
 329 --------------------
 330
 331 * Fixed several bugs in the interrupt handler and callback routines.
 332 (reported by Paul Warren, Alsys)
