  43 Mon Aug 12 17:04:58 1996  Stu Grossman  (grossman@critters.cygnus.com)
  44
  45         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
  46         necessary.
  47         * (port_init):  Don't even *try* to open pty's under _WIN32.
  48         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.

  63         when can't open pty's.
  64         * exec.c:  Add two new instructions: smul, and divscc.
  65         * interf.c (flush_windows):  New routine to flush the register
  66         windows out to the stack just before returning to GDB.  Makes
  67         backtraces work much better.

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