 104
 105         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't

 153
 154         * func.c(bfd_load): Don't try to print the filename if the pfbd is
 155         NULL.
 156         * interf.c(sim_load): Pass the whole string, not just the first
 157         byte.
 158
 159 Version 2.1 26-02-96
 160 --------------------
 161
 162 * Fixed bug in "go" command.
 163
 164 version 2.0 05-02-96
 165 --------------------
 166
 167 * Fixed bug in interrupt force register (erc32.c).
 168
 169 * Change file load function to use bfd_openr.
 170
 171 * SIS should now be endian independent.
 172
 173 version 1.8 24-11-95
 174 --------------------
 175
 176 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 177   the resource dependencies right.
 178
 179 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 180   but no FPU trap is generated.
 181
 182 version 1.7.1 31-10-95
 183 --------------------
 184
 185 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 186   the FPU stays in execute mode.
 187
 188 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 189
 190
 191 version 1.7 25-10-95
 192 --------------------
 193
 194 * Interrupt during annuled instruction corrupted return address - fixed.
 195
 196
 197 version 1.6.2 25-10-95
 198 --------------------
 199
 200 * Added -DFAST_UART to Makefile
 201
 202
 203 version 1.6.1 24-10-95
 204 --------------------
 205
 206 * Fixed bug in STDFQ which caused bus error
 207
 208
 209 version 1.6 02-10-95
 210 --------------------
 211
 212 * Modified srt0.s to include code that initiates registers in IU and FPU
 213   and initializes the data segment. The simulator 'load' command does not
 214   longer initialize the data segment!
 215
 216 * Corrected MEC timer operation; scalers now divide the frequency by
 217   (scaler_value + 1).
 218
 219 * MEC breakpoints are not checked during store operation
 220
 221
 222 version 1.5 14-09-95
 223 --------------------
 224
 225 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 226
 227 * Fixed bug that allowed an annuled instruction to cause memory exception.
 228
 229 * The *ws parameter in mem.c should now contain the number of waitstates
 230   required by the memory access (was total number of cycles).
 231
 232 * The supplied srt0.s now clears the BSS (thanks Joel).
 233
 234 version 1.4 22-08-95
 235 --------------------
 236
 237 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 238 some problems on solaris 2.x machines.
 239
 240 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 241 may suffer a bit ...
 242
 243 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 244
 245 version 1.3 26-07-95
 246 --------------------
 247
 248 * Fixed bug in mulscc instruction (how could that ever have worked?)
 249
 250 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 251
 252 version 1.2 13-07-95
 253 --------------------
 254
 255 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 256 one interrupt pending)
 257
 258 * Fixed updating of condition codes during logical instructions (carry and
 259 overflow were not reset)
 260
 261 * Fixed bug in WRTBR (tt field was wrongly over-written)
 262
 263 version 1.1 07-07-95
 264 --------------------
 265
 266 * Fixed several bugs in the interrupt handler and callback routines.
 267 (reported by Paul Warren, Alsys)
