 172         NULL.
 173         * interf.c(sim_load): Pass the whole string, not just the first
 174         byte.
 175
 176 Version 2.1 26-02-96
 177 --------------------
 178
 179 * Fixed bug in "go" command.
 180
 181 version 2.0 05-02-96
 182 --------------------
 183
 184 * Fixed bug in interrupt force register (erc32.c).
 185
 186 * Change file load function to use bfd_openr.
 187
 188 * SIS should now be endian independent.
 189
 190 version 1.8 24-11-95
 191 --------------------
 192
 193 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 194   the resource dependencies right.
 195
 196 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 197   but no FPU trap is generated.
 198
 199 version 1.7.1 31-10-95
 200 --------------------
 201
 202 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 203   the FPU stays in execute mode.
 204
 205 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 206
 207
 208 version 1.7 25-10-95
 209 --------------------
 210
 211 * Interrupt during annuled instruction corrupted return address - fixed.
 212
 213
 214 version 1.6.2 25-10-95
 215 --------------------
 216
 217 * Added -DFAST_UART to Makefile
 218
 219
 220 version 1.6.1 24-10-95
 221 --------------------
 222
 223 * Fixed bug in STDFQ which caused bus error
 224
 225
 226 version 1.6 02-10-95
 227 --------------------
 228
 229 * Modified srt0.s to include code that initiates registers in IU and FPU
 230   and initializes the data segment. The simulator 'load' command does not
 231   longer initialize the data segment!
 232
 233 * Corrected MEC timer operation; scalers now divide the frequency by
 234   (scaler_value + 1).
 235
 236 * MEC breakpoints are not checked during store operation
 237
 238
 239 version 1.5 14-09-95
 240 --------------------
 241
 242 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 243
 244 * Fixed bug that allowed an annuled instruction to cause memory exception.
 245
 246 * The *ws parameter in mem.c should now contain the number of waitstates
 247   required by the memory access (was total number of cycles).
 248
 249 * The supplied srt0.s now clears the BSS (thanks Joel).
 250
 251 version 1.4 22-08-95
 252 --------------------
 253
 254 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 255 some problems on solaris 2.x machines.
 256
 257 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 258 may suffer a bit ...
 259
 260 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 261
 262 version 1.3 26-07-95
 263 --------------------
 264
 265 * Fixed bug in mulscc instruction (how could that ever have worked?)
 266
 267 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 268
 269 version 1.2 13-07-95
 270 --------------------
 271
 272 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 273 one interrupt pending)
 274
 275 * Fixed updating of condition codes during logical instructions (carry and
 276 overflow were not reset)
 277
 278 * Fixed bug in WRTBR (tt field was wrongly over-written)
 279
 280 version 1.1 07-07-95
 281 --------------------
 282
 283 * Fixed several bugs in the interrupt handler and callback routines.
 284 (reported by Paul Warren, Alsys)
