   2 version 2.0 05-02-96
   3 --------------------
   4
   5 * Switched to bfd library. Any supported format (elf, coff, ...) can be used.
   6 * The UART devices can be set through -uart1 and -uart2 switches.
   7 * Switched to GNU readline.
   8 * Added -c option to run batch files at startup
   9 * 'reg' command can show different register windows (eg 'reg w3').
  10 * Use 'help' for online help on simulator commands
  11
  12 version 1.8.1 20-01-96
  13 --------------------
  14
  15 * added -mevrev0 switch to simulate MEC rev.0 bugs in timer and uart
  16
  17 * added -iurev0 switch to simulate IU rev.0 jmpl/restore bug
  18
  19 * Added sis command 'batch' to run batch files
  20
  21
  22 version 1.8 30-10-95
  23 --------------------
  24
  25 * Added s-record support. Use the '-s' switch with sis or the 'load' command.
  26
  27 * IU load dependencies are now modelled
  28
  29 version 1.7 30-10-95
  30 --------------------
  31
  32 * Power-down mode implemented in erc32.c.
  33
  34 * Performance display shows the ratio between simulator-time and real-time.
  35
  36
  37 version 1.6.2 25-10-95
  38 --------------------
  39
  40 * The UARTs can now be run at a given speed (simulator time) to better
  41   simulate the behaviour of interrupt routines. The "true mode" is
  42   selected through a compile switch in the makefile.
  43
  44
  45 version 1.6 28-09-95
  46 --------------------
  47
  48 * Major reorganisation of the code. mec.c and mem.c merged into erc32.c.
  49
  50 * The load command does NOT longer load the initialised data at an address
  51   defined by .bdata. This is done in srt0.s using _environ.
  52
  53 * Additional MEC functionallity added - software reset, memory access
  54   protection and waitstate configuration register.
  55
  56 * interf.c - a GDB interface added
  57
  58 * -v switch (verbose) added
  59
  60 version 1.5 14-09-95
  61 --------------------
  62
  63 * Added a instruction trace buffer, enabled through the 'hist' command.
  64
  65 * Added a 'perf' command to display statistics such as instruction mix,
  66   CPI, FPU holds etc.
  67
  68 * Added -nfp switch to disable FPU.
  69
  70 * Added -freq switch to set simulated frequency.
  71
  72 version 1.4 22-08-95
  73 --------------------
  74
  75 * A -g is provided for those who have problems with GNU readline().
  76
  77 version 1.3 26-07-95
  78 --------------------
  79
  80 * No major news, just a bug fix release ...
  81
  82
  83 version 1.2 13-07-95
  84 --------------------
  85
  86 * Added setting of IU registers through the 'reg' command. See README.
  87
  88 * The GNU readline() function is used for command input. However, a
  89 ctrl-D still kills the simulator ...
  90
  91
  92 version 1.1 07-07-95
  93 --------------------
  94
  95
  96 * Added a 'go' command
  97
  98 * Added cycle counting for interrupt overhead.
  99
 100 * Function 'get_mem_ptr' takes one more parameter to avoid segmentation
 101    faults if a.out files are loaded outside the simulated memory. See README.
 102
 103 * Added user-defined function sim_stop().
 104
 105 * Added a reset command. See README.
 106
 107 * Implemented buffered output for MEC uarts to improve output speed.
