  96
  97         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't

 147         NULL.
 148         * interf.c(sim_load): Pass the whole string, not just the first
 149         byte.
 150
 151 Version 2.1 26-02-96
 152 --------------------
 153
 154 * Fixed bug in "go" command.
 155
 156 version 2.0 05-02-96
 157 --------------------
 158
 159 * Fixed bug in interrupt force register (erc32.c).
 160
 161 * Change file load function to use bfd_openr.
 162
 163 * SIS should now be endian independent.
 164
 165 version 1.8 24-11-95
 166 --------------------
 167
 168 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 169   the resource dependencies right.
 170
 171 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 172   but no FPU trap is generated.
 173
 174 version 1.7.1 31-10-95
 175 --------------------
 176
 177 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 178   the FPU stays in execute mode.
 179
 180 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 181
 182
 183 version 1.7 25-10-95
 184 --------------------
 185
 186 * Interrupt during annuled instruction corrupted return address - fixed.
 187
 188
 189 version 1.6.2 25-10-95
 190 --------------------
 191
 192 * Added -DFAST_UART to Makefile
 193
 194
 195 version 1.6.1 24-10-95
 196 --------------------
 197
 198 * Fixed bug in STDFQ which caused bus error
 199
 200
 201 version 1.6 02-10-95
 202 --------------------
 203
 204 * Modified srt0.s to include code that initiates registers in IU and FPU
 205   and initializes the data segment. The simulator 'load' command does not
 206   longer initialize the data segment!
 207
 208 * Corrected MEC timer operation; scalers now divide the frequency by
 209   (scaler_value + 1).
 210
 211 * MEC breakpoints are not checked during store operation
 212
 213
 214 version 1.5 14-09-95
 215 --------------------
 216
 217 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 218
 219 * Fixed bug that allowed an annuled instruction to cause memory exception.
 220
 221 * The *ws parameter in mem.c should now contain the number of waitstates
 222   required by the memory access (was total number of cycles).
 223
 224 * The supplied srt0.s now clears the BSS (thanks Joel).
 225
 226 version 1.4 22-08-95
 227 --------------------
 228
 229 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 230 some problems on solaris 2.x machines.
 231
 232 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 233 may suffer a bit ...
 234
 235 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 236
 237 version 1.3 26-07-95
 238 --------------------
 239
 240 * Fixed bug in mulscc instruction (how could that ever have worked?)
 241
 242 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 243
 244 version 1.2 13-07-95
 245 --------------------
 246
 247 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 248 one interrupt pending)
 249
 250 * Fixed updating of condition codes during logical instructions (carry and
 251 overflow were not reset)
 252
 253 * Fixed bug in WRTBR (tt field was wrongly over-written)
 254
 255 version 1.1 07-07-95
 256 --------------------
 257
 258 * Fixed several bugs in the interrupt handler and callback routines.
 259 (reported by Paul Warren, Alsys)
