 183         NULL.
 184         * interf.c(sim_load): Pass the whole string, not just the first
 185         byte.
 186
 187 Version 2.1 26-02-96
 188 --------------------
 189
 190 * Fixed bug in "go" command.
 191
 192 version 2.0 05-02-96
 193 --------------------
 194
 195 * Fixed bug in interrupt force register (erc32.c).
 196
 197 * Change file load function to use bfd_openr.
 198
 199 * SIS should now be endian independent.
 200
 201 version 1.8 24-11-95
 202 --------------------
 203
 204 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 205   the resource dependencies right.
 206
 207 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 208   but no FPU trap is generated.
 209
 210 version 1.7.1 31-10-95
 211 --------------------
 212
 213 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 214   the FPU stays in execute mode.
 215
 216 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 217
 218
 219 version 1.7 25-10-95
 220 --------------------
 221
 222 * Interrupt during annuled instruction corrupted return address - fixed.
 223
 224
 225 version 1.6.2 25-10-95
 226 --------------------
 227
 228 * Added -DFAST_UART to Makefile
 229
 230
 231 version 1.6.1 24-10-95
 232 --------------------
 233
 234 * Fixed bug in STDFQ which caused bus error
 235
 236
 237 version 1.6 02-10-95
 238 --------------------
 239
 240 * Modified srt0.s to include code that initiates registers in IU and FPU
 241   and initializes the data segment. The simulator 'load' command does not
 242   longer initialize the data segment!
 243
 244 * Corrected MEC timer operation; scalers now divide the frequency by
 245   (scaler_value + 1).
 246
 247 * MEC breakpoints are not checked during store operation
 248
 249
 250 version 1.5 14-09-95
 251 --------------------
 252
 253 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 254
 255 * Fixed bug that allowed an annuled instruction to cause memory exception.
 256
 257 * The *ws parameter in mem.c should now contain the number of waitstates
 258   required by the memory access (was total number of cycles).
 259
 260 * The supplied srt0.s now clears the BSS (thanks Joel).
 261
 262 version 1.4 22-08-95
 263 --------------------
 264
 265 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 266 some problems on solaris 2.x machines.
 267
 268 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 269 may suffer a bit ...
 270
 271 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 272
 273 version 1.3 26-07-95
 274 --------------------
 275
 276 * Fixed bug in mulscc instruction (how could that ever have worked?)
 277
 278 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 279
 280 version 1.2 13-07-95
 281 --------------------
 282
 283 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 284 one interrupt pending)
 285
 286 * Fixed updating of condition codes during logical instructions (carry and
 287 overflow were not reset)
 288
 289 * Fixed bug in WRTBR (tt field was wrongly over-written)
 290
 291 version 1.1 07-07-95
 292 --------------------
 293
 294 * Fixed several bugs in the interrupt handler and callback routines.
 295 (reported by Paul Warren, Alsys)
