  43
  44         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
  45         necessary.

  47         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.

  63         * exec.c:  Add two new instructions: smul, and divscc.
  64         * interf.c (flush_windows):  New routine to flush the register
  65         windows out to the stack just before returning to GDB.  Makes
  66         backtraces work much better.

  88
  89         * Makefile.in (end.h): Use explicit ./ when running end.
  90
  91 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
  92
  93         * func.c(bfd_load): Don't try to print the filename if the pfbd is
  94         NULL.
  95         * interf.c(sim_load): Pass the whole string, not just the first
  96         byte.
  97
  98 Version 2.1 26-02-96
  99 --------------------
 100
 101 * Fixed bug in "go" command.
 102
 103 version 2.0 05-02-96
 104 --------------------
 105
 106 * Fixed bug in interrupt force register (erc32.c).
 107
 108 * Change file load function to use bfd_openr.
 109
 110 * SIS should now be endian independent.
 111
 112 version 1.8 24-11-95
 113 --------------------
 114
 115 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 116   the resource dependencies right.
 117
 118 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 119   but no FPU trap is generated.
 120
 121 version 1.7.1 31-10-95
 122 --------------------
 123
 124 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 125   the FPU stays in execute mode.
 126
 127 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 128
 129
 130 version 1.7 25-10-95
 131 --------------------
 132
 133 * Interrupt during annuled instruction corrupted return address - fixed.
 134
 135
 136 version 1.6.2 25-10-95
 137 --------------------
 138
 139 * Added -DFAST_UART to Makefile
 140
 141
 142 version 1.6.1 24-10-95
 143 --------------------
 144
 145 * Fixed bug in STDFQ which caused bus error
 146
 147
 148 version 1.6 02-10-95
 149 --------------------
 150
 151 * Modified srt0.s to include code that initiates registers in IU and FPU
 152   and initializes the data segment. The simulator 'load' command does not
 153   longer initialize the data segment!
 154
 155 * Corrected MEC timer operation; scalers now divide the frequency by
 156   (scaler_value + 1).
 157
 158 * MEC breakpoints are not checked during store operation
 159
 160
 161 version 1.5 14-09-95
 162 --------------------
 163
 164 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 165
 166 * Fixed bug that allowed an annuled instruction to cause memory exception.
 167
 168 * The *ws parameter in mem.c should now contain the number of waitstates
 169   required by the memory access (was total number of cycles).
 170
 171 * The supplied srt0.s now clears the BSS (thanks Joel).
 172
 173 version 1.4 22-08-95
 174 --------------------
 175
 176 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 177 some problems on solaris 2.x machines.
 178
 179 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 180 may suffer a bit ...
 181
 182 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 183
 184 version 1.3 26-07-95
 185 --------------------
 186
 187 * Fixed bug in mulscc instruction (how could that ever have worked?)
 188
 189 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 190
 191 version 1.2 13-07-95
 192 --------------------
 193
 194 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 195 one interrupt pending)
 196
 197 * Fixed updating of condition codes during logical instructions (carry and
 198 overflow were not reset)
 199
 200 * Fixed bug in WRTBR (tt field was wrongly over-written)
 201
 202 version 1.1 07-07-95
 203 --------------------
 204
 205 * Fixed several bugs in the interrupt handler and callback routines.
