+ * chipKIT Max32 board.
+ * Sparkfun UBW32 board.
+ * Maximite computer.
+ * Microchip Explorer 16 board, with PIC32 CAN-USB plug-in module and SD & MMC pictail.
+ * Microchip PIC32 USB or Ethernet Starter Kit, with I/O Expansion board and SD & MMC pictail.
+ * Olimex Duinomite, Duinomite-Mini and Duinomite-Mega boards.
+ * Olimex Pinguino-Micro board with PIC32MX795F512H microcontroller.
+ * eflightworks DIP board.
+
+
+Build
+~~~~~
+By default, the system is configured for the Max32 board.
+To select another target board, edit a top-level Makefile
+and change a TARGET value under section "Select target board":
+
+    TARGET = $(UBW32)       # for the UBW32 board with USB console
+    TARGET = $(UBW32UART)   # for the UBW32 board with UART console
+    TARGET = $(MAXIMITE)    # for the Maximite board
+    TARGET = $(EXPLORER16)  # for the Explorer 16 board
+    TARGET = $(STARTERKIT)  # for the PIC32 USB or Ethernet Starter Kit
+    TARGET = $(MAX32)       # default
+    TARGET = $(DUINOMITE)   # for the Duinomite board
+    TARGET = $(PINGUINO)    # for the Pinguino-Micro board
+    TARGET = $(DIP)         # for the DIP board
+
+You can also change a desired filesystem size and swap area size,
+as required.  Default is:
+
+    FS_KBYTES   = 16384
+    SWAP_KBYTES = 2048
+
+To compile the kernel and build a filesystem image, run:
+
+    make
+
+A resulting root filesystem image is in file `filesys.img`.
+A kernel is in file `unix.hex` in your target board subdirectory.
+
+
+Filesystem image
+~~~~~~~~~~~~~~~~
+You need to put a filesystem image on a SD card.  On Windows, use
+Win32DiskImager utility (https://launchpad.net/win32-image-writer/+download).
+On Linux, run:
+
+    sudo dd if=filesys.img of=/dev/XYZ
+
+Here `XYZ` is a device name of SD card, as recognized by Linux (sdb in my case).
+
+
+Install kernel
+~~~~~~~~~~~~~~
+Kernel image should be written to PIC32 flash memory.  The procedure depends
+on a board used.
+
+Max32 board:
+    cd sys/pic32/ubw32
+    AVRTOOLS=/Applications/Mpide.app/Contents/Resources/Java/hardware/tools
+    $AVRTOOLS/bin/avrdude -C$AVRTOOLS/etc/avrdude.conf -c stk500v2 -p pic32 \
+        -P /dev/tty.usbserial-* -b 115200 -v -U flash:w:unix.hex:i
+
+    Here you need to change AVRTOOLS path and tty name according to your system.
+
+UBW32 board:
+    Use a pic32prog utility (http://code.google.com/p/pic32prog/)
+    and a USB cable to install a kernel:
+
+    pic32prog sys/pic32/ubw32/unix.hex
+
+Maximite:
+    Use the bootload program for Windows, available for download by link:
+    http://geoffg.net/Downloads/Maximite/Maximite_Update_V2.7B.zip
+
+Explorer 16 board:
+    There is an auxiliary PIC18 chip on the Explorer 16 board, which can be
+    used as a built-in programmer device.  You will need a PICkit 2 adapter
+    to install a needed firmware, as described in article:
+    http://www.paintyourdragon.com/?p=51
+    (section "Hack #2: Lose the PICkit 2, Save $35").
+    This should be done only once.
+
+    Then, you can use a pic32prog utility (http://code.google.com/p/pic32prog/)
+    and a USB cable to install a kernel:
+
+    pic32prog sys/pic32/explorer16/unix.hex
+
+PIC32 Starter Kit:
+    Use PICkit 2 adapter and software to install a boot loader from

+Simulator
+~~~~~~~~~
+You can use a MIPS32 simulator to develop a debug a RetroBSD software,
+without a need for hardware board.  By default, a simulator is configured
+to imitate a Max32 board.  To build it:
+
+    cd tools/virtualmips
+    make
+
+Run it:
+
+    ./pic32
+
+Configuration of simulated board is stored in file `pic32_max32.conf`.

-
-
-## Build
-
-By default, the system is configured for the Max32 board.
-To select another target board, edit a top-level user-specific Makefile called "Makefile.user"
-and set a TARGET value:
-
-```Makefile
-TARGET = $(UBW32)          # for the UBW32 board with USB console
-TARGET = $(UBW32UART)      # for the UBW32 board with UART console
-TARGET = $(UBW32UARTSDRAM) # for the UBW32 boars with UART console and 8MB SRAM ramdisk
-TARGET = $(MAXIMITE)       # for the Maximite board
-TARGET = $(MAXCOLOR)       # for the Colour Maximite board
-TARGET = $(EXPLORER16)     # for the Explorer 16 board
-TARGET = $(STARTERKIT)     # for the PIC32 USB or Ethernet Starter Kit
-TARGET = $(MAX32)          # default
-TARGET = $(MAX32-ETH)      # for the chipKIT MAX32 board with Arduino Ethernet shield
-TARGET = $(DUINOMITE)      # for the Duinomite board with USB console
-TARGET = $(DUINOMITEUART)  # for the Duinomite board with UART console
-TARGET = $(DUINOMITEE)     # for the Duinomite E board with USB console
-TARGET = $(DUINOMITEEUART) # for the Duinomite E board with UART console
-TARGET = $(PINGUINO)       # for the Pinguino-Micro board
-TARGET = $(DIP)            # for the DIP board
-TARGET = $(BAREMETAL)      # Bare PIC32 chip on a breakout board
-TARGET = $(FUBARINO)       # Fubarino SD board
-TARGET = $(FUBARINOBIG)    # Fubarino SD board with 8MB SRAM RAMDISK
-TARGET = $(MMBMX7)         # MMB MX7 board
-```
-
-You can also change a desired filesystem size and swap area size,
-as required.  Default is:
-```Makefile
-FS_KBYTES   = 16384
-SWAP_KBYTES = 2048
-```
-To compile the kernel and build a filesystem image, run:
-
-```shell
-$ make
-```
-
-A resulting root filesystem image is in file `sdcard.rd`.
-A kernel is in file `unix.hex` in your target board subdirectory.
-
-
-### Filesystem image
-
-You need to put a filesystem image on a SD card.  On Windows, use
-Win32DiskImager utility (https://launchpad.net/win32-image-writer/+download).
-On Linux, run:
-
-```shell
-$ sudo dd if=sdcard.rd of=/dev/XYZ
-```
-
-Here `XYZ` is a device name of SD card, as recognized by Linux (sdb in my case).
-
-
-### Install kernel
-
-Kernel image should be written to PIC32 flash memory.  The procedure depends
-on a board used.
-
-#### Max32 board:
-```shell
-$ cd sys/pic32/ubw32
-$ AVRTOOLS=/Applications/Mpide.app/Contents/Resources/Java/hardware/tools/avr
-    $AVRTOOLS/bin/avrdude -C$AVRTOOLS/etc/avrdude.conf -c stk500v2 -p pic32 \
-    -P /dev/tty.usbserial-* -b 115200 -v -U flash:w:unix.hex:i
-```
-
-Here you need to change AVRTOOLS path and tty name according to your system.
-
-#### UBW32 board:
-Use a pic32prog utility (http://code.google.com/p/pic32prog/)
-and a USB cable to install a kernel:
-
-```shell
-$ pic32prog sys/pic32/ubw32/unix.hex
-```
-
-#### Maximite:
-Use the bootload program for Windows, available for download by link:
-http://geoffg.net/Downloads/Maximite/Maximite_Update_V2.7B.zip
-
-#### Explorer 16 board:
-There is an auxiliary PIC18 chip on the Explorer 16 board, which can be
-used as a built-in programmer device.  You will need a PICkit 2 adapter
-to install a needed firmware, as described in article:
-http://www.paintyourdragon.com/?p=51
-(section "Hack #2: Lose the PICkit 2, Save $35").
-This should be done only once.
-
-Then, you can use a pic32prog utility (http://code.google.com/p/pic32prog/)
-and a USB cable to install a kernel:
-
-``` shell
-$ pic32prog sys/pic32/explorer16/unix.hex
-```
-
-#### PIC32 Starter Kit:
-Use PICkit 2 adapter and software to install a boot loader from
-file `sys/pic32/starter-kit/boot.hex`.  This should be done only once.
-
-Then, you can use a pic32prog utility (http://code.google.com/p/pic32prog/)
-and a USB cable to install a kernel:
-
-```shell
-$ pic32prog sys/pic32/starter-kit/unix.hex
-```
-

-without a need for hardware board.  By default, a simulator is configured
-to imitate a Max32 board.  To build it:
-
-```shell
-$ cd tools/virtualmips
-$ make
-```
-
-Run it:
-
-```shell
-$ ./pic32
-```
-
-Configuration of simulated board is stored in file `pic32_max32.conf`.
-
-## Build packages
-
-
-For building under Ubuntu you need the following packages installed:
-
-```shell
-$ sudo apt-get install byacc libelf-dev
-```

-====== A Tutorial Introduction to ADB ======
-
-//J. F. Maranzano, S. R. Bourne//
-//May 5, 1977//
-
-===== 1.  Introduction =====
-
-ADB  is  a  new  debugging program that is available on
-UNIX.  It provides capabilities to look  at  "core"  files
-resulting  from  aborted programs, print output in a variety
-of formats, patch files,  and  run  programs  with  embedded
-breakpoints.   This  document  provides examples of the more
-useful features of ADB.  The reader is expected to be familiar
-with the basic commands on UNIX with the C language, and
-with References 1, 2 and 3.
-
-
-===== 2. A Quick Survey =====
-
-==== 2.1. Invocation ====
-
-ADB is invoked as:
-          **adb objfile corefile**
-where ''objfile'' is an executable UNIX file and ''corefile''  is  a
-core image file.  Many times this will look like:
-          **adb a.out core**
-or more simply:
-          **adb**
-where  the  defaults  are  ''a.out'' and ''core'' respectively.  The
-filename minus (-) means ignore this argument as in:
-          **adb - core**
-
-ADB has requests  for  examining  locations  in  either file.
-The **?**  request examines the contents of ''objfile'',
-the **/** request examines the ''corefile''.  The general form of  these
-requests is:
-          **address ? format**
-or
-          **address / format**
-
-==== 2.2. Current Address ====
-
-ADB maintains a current address, called dot, similar in
-function to the current pointer in the UNIX editor.  When an
-address is entered, the current address is set to that location,
-so that:
-          **0126?i**
-sets dot to octal 126 and prints  the  instruction  at  that
-address.  The request:
-          **.,10/d**
-prints  10  decimal  numbers  starting  at dot.  Dot ends up
-referring to the address of the  last  item  printed.   When
-used  with  the  **?** or **/** requests, the current address can be
-advanced by typing newline; it can be decremented by  typing **^**.
-
-Addresses  are represented by expressions.  Expressions
-are made up from decimal, octal, and  hexadecimal  integers,
-and  symbols from the program under test.  These may be combined
-with the operators +, -, *, %  (integer  division),  &
-(bitwise and), | (bitwise inclusive or),  # (round up to the
-next multiple), and ~ (not).  (All arithmetic within ADB  is
-32  bits.)   When typing a symbolic address for a C program,
-the user can type ''name'' or ''_name'';  ADB  will  recognize  both
-forms.
-
-==== 2.3. Formats ====
-
-To print data, a user specifies a collection of letters
-and characters that describe the  format  of  the  printout.
-Formats  are "remembered" in the sense that typing a request
-without one will cause the new printout  to  appear  in  the
-previous  format.   The following are the most commonly used
-format letters.
-
-|| b || one byte in octal ||
-|| c || one byte as a character ||
-|| o || one word in octal ||
-|| d || one word in decimal ||
-|| f || two words in floating point ||
-|| i || PDP 11 instruction ||
-|| s || a null terminated character string ||
-|| a || the value of dot ||
-|| u || one word as unsigned integer ||
-|| n || print a newline ||
-|| r || print a blank space ||
-|| ^ || backup dot ||
-
-(Format letters are also available for  "long"  values,  for
-example,  `**D**'  for long decimal, and `**F**' for double floating
-point.)  For other formats see the ADB manual.
-
-==== 2.4. General Request Meanings ====
-
-The general form of a request is:
-          **address,count command modifier**
-which sets `dot' to ''address'' and executes the  command  ''count''
-times.
-
-The  following  table illustrates some general ADB command meanings:
-
-^^ Command ^^ Meaning ^^
-|| ?       || Print contents from ''a.out'' file ||
-|| /       || Print contents from ''core'' file ||
-|| =       || Print value of "dot" ||
-|| :       || Breakpoint control ||
-|| $       || Miscellaneous requests ||
-|| ;       || Request separator ||
-|| !       || Escape to shell ||
-
-ADB catches signals, so a user cannot use a quit signal
-to  exit from ADB.  The request $q or $Q (or cntl-D) must be
-used to exit from ADB.
-
-===== 3. Debugging C Programs =====
-
-==== 3.1. Debugging A Core Image ====
-
-Consider the C program in Figure  1.   The  program  is
-used  to  illustrate  a  common error made by C programmers.
-The object of the program is to change the lower case "t" to
-upper  case in the string pointed to by ''charp'' and then write
-the character string to the file indicated  by  argument  1.
-The  bug  shown  is  that the character "T" is stored in the
-pointer ''charp'' instead of the string  pointed  to  by  ''charp''.
-Executing the program produces a core file because of an out
-of bounds memory reference.
-
-ADB is invoked by:
-          **adb a.out core**
-The first debugging request:
-          **$c**
-is used to  give  a  C  backtrace  through  the  subroutines
-called.   As  shown in Figure 2 only one function (''main'') was
-called and the arguments ''argc'' and ''argv'' have octal values  02
-and 0177762 respectively.  Both of these values look reasonable;
-02 = two arguments, 0177762  =  address  on  stack  of
-parameter vector.
-The next request:
-          **$C**
-is  used to give a C backtrace plus an interpretation of all
-the local variables in each function  and  their  values  in
-octal.   The  value of the variable ''cc'' looks incorrect since
-''cc'' was declared as a character.
-
-The next request:
-          **$r**
-prints out the registers including the program  counter  and
-an interpretation of the instruction at that location.
-
-The request:
-          **$e**
-prints out the values of all external variables.
-
-A map exists for each file handled by ADB.  The map for
-the ''a.out'' file is referenced by **?** whereas the map  for  ''core**
-file  is referenced by **/**.  Furthermore, a good rule of thumb
-is to use **?** for instructions and **/** for data when looking  at
-programs.  To print out information about the maps type:
-          **$m**
-This  produces  a  report of the contents of the maps.  More
-about these maps later.
-
-In our example, it is useful to see the contents of the
-string pointed to by ''charp.''  This is done by:
-          ***charp/s**
-which says use ''charp'' as a pointer in the ''core'' file and print
-the  information  as  a  character  string.   This  printout
-clearly  shows  that  the  character  buffer was incorrectly
-overwritten and helps  identify  the  error.   Printing  the
-locations  around  ''charp''  shows that the buffer is unchanged
-but that the pointer is destroyed.  Using ADB similarly,  we
-could  print  information about the arguments to a function.
-The request:
-          **main.argc/d**
-prints the decimal ''core'' image value of the argument ''argc''  in
-the function //main.//
-The request:
-          ***main.argv,3/o**
-prints  the  octal  values  of  the  three consecutive cells
-pointed to by ''argv'' in the function ''main.''   Note  that  these
-values  are  the addresses of the arguments to main.  Therefore:
-          **0177770/s**
-prints the ASCII value of the first argument.   Another  way
-to print this value would have been
-          ***"/s**
-The " means ditto which remembers the last address typed, in
-this case ''main.argc'' ; the ** * ** instructs ADB to use the address
-field of the ''core'' file as a pointer.
-
-The request:
-          **.=o**
-prints the current address (not its contents) in octal which
-has been set to the address of the first argument.  The current
-address, dot, is used by ADB to "remember" its current
-location.  It allows the user to reference  locations  relative
-to the current address, for example:
-          **.-10/d**
-
-==== 3.2. Multiple Functions ====
-
-Consider  the  C program illustrated in Figure 3.  This
-program calls functions ''f,'' ''g,''  and  ''h''  until  the  stack  is
-exhausted and a core image is produced.
-
-Again you can enter the debugger via:
-          **adb**
-which  assumes  the  names ''a.out'' and ''core'' for the executable
-file and core image file respectively.  The request:
-          **$c**
-will fill a page of backtrace references to  //f,''  ''g,''  and  ''h.//
-Figure  4  shows an abbreviated list (typing ''DEL'' will terminate
-the output and bring you back to ADB request level).
-
-The request:
-          **,5$C**
-prints the five most recent activations.
-
-Notice that each function (''f,g,h'') has a counter of  the
-number of times it was called.
-
-The request:
-          **fcnt/d**
-prints  the decimal value of the counter for the function //f.//
-Similarly ''gcnt'' and ''hcnt'' could  be  printed.   To  print  the
-value  of  an  automatic  variable,  for example the decimal
-value of ''x'' in the last call of the function ''h,'' type:
-          **h.x/d**
-It is currently not possible  in  the  exported  version  to
-print  stack frames other than the most recent activation of
-a function.  Therefore, a user can print everything with  **$C**
-or the occurrence of a variable in the most recent call of a
-function.  It is possible with the **$C** request,  however,  to
-print the stack frame starting at some address as **address$C.**
-
-==== 3.3. Setting Breakpoints ====
-
-Consider  the  C  program  in  Figure 5.  This program,
-which changes tabs into blanks,  is  adapted  from  //Software//
-''Tools'' by Kernighan and Plauger, pp. 18-27.
-
-We  will run this program under the control of ADB (see
-Figure 6a) by:
-          **adb a.out -**
-Breakpoints are set in the program as:
-          **address:b  [request]**
-The requests:
-          **settab+4:b**
-          **fopen+4:b**
-          **getc+4:b**
-          **tabpos+4:b**
-set breakpoints at the start of these functions.  C does not
-generate  statement  labels.   Therefore it is currently not
-possible to plant breakpoints at locations other than  function
-entry points without a knowledge of the code generated
-by the C compiler.  The above addresses are entered as  **symbol+4**
-so that they will appear in any C backtrace since the
-first instruction of each function is a call to the  C  save
-routine (''csv'').  Note that some of the functions are from the
-C library.
-
-To print the location of breakpoints one types:
-          **$b**
-The display  indicates  a  ''count''  field.   A  breakpoint  is
-bypassed  //count'' ''-1'' times before causing a stop.  The ''command//
-field indicates the ADB requests to be  executed  each  time
-the  breakpoint  is  encountered.  In our example no //command//
-fields are present.
-
-By displaying the original instructions at the function
-''settab''  we  see  that the breakpoint is set after the jsr to
-the C save routine.  We can display the  instructions  using
-the ADB request:
-          **settab,5?ia**
-This  request  displays five instructions starting at //settab//
-with the addresses  of  each  location  displayed.   Another
-variation is:
-          **settab,5?i**
-which  displays  the  instructions  with  only  the starting
-address.
-
-Notice that we accessed the addresses  from  the  //a.out//
-file  with  the  **?**  command.   In  general when asking for a
-printout of multiple items, ADB  will  advance  the  current
-address  the  number  of  bytes  necessary  to  satisfy  the
-request; in the above example five  instructions  were  displayed
-and  the  current  address was advanced 18 (decimal)
-bytes.
-
-To run the program one simply types:
-          **:r**
-To delete a breakpoint, for instance the entry to the  function
-''settab,'' one types:
-          **settab+4:d**
-To  continue  execution  of  the program from the breakpoint
-type:
-          **:c**
-
-Once the program has  stopped  (in  this  case  at  the
-breakpoint  for  ''fopen),'' ADB requests can be used to display
-the contents of memory.  For example:
-          **$C**
-to display a stack trace, or:
-          **tabs,3/8o**
-to print three lines of 8  locations  each  from  the  array
-called ''tabs.''  By this time (at location ''fopen)'' in the C program,
-''settab'' has been called and should have set  a  one  in
-every eighth location of //tabs.//
-
-==== 3.4. Advanced Breakpoint Usage ====
-
-We continue execution of the program with:
-          **:c**
-See Figure 6b.  ''Getc'' is called three times and  the contents
-of the variable ''c'' in the function ''main''  are  displayed  each
-time.   The  single  character  on the left hand edge is the
-output from the C program.  On the third occurrence of  //getc//
-the  program  stops.   We  can  look  at  the full buffer of
-characters by typing:
-          **ibuf+6/20c**
-When we continue the program with:
-          **:c**
-we hit our first breakpoint at ''tabpos'' since there is  a  tab
-following the "This" word of the data.
-
-Several breakpoints of ''tabpos'' will occur until the program
-has changed the tab into equivalent blanks.   Since  we
-feel that ''tabpos'' is working, we can remove the breakpoint at
-that location by:
-          **tabpos+4:d**
-If the program is continued with:
-          **:c**
-it resumes normal execution after ADB prints the message
-          **a.out:running**
-
-The UNIX quit and interrupt signals act on  ADB  itself
-rather than on the program being debugged.  If such a signal
-occurs then the program being debugged is stopped  and  control
-is returned to ADB.  The signal is saved by ADB and is
-passed on to the test program if:
-          **:c**
-is typed.  This can be useful when  testing  interrupt  handling
-routines.   The  signal  is not passed on to the test
-program if:
-          **:c  0**
-is typed.
-
-Now let us reset the breakpoint at ''settab''  and  display
-the instructions located there when we reach the breakpoint.
-This is accomplished by:
-          **settab+4:b  settab,5?ia**  (*
-It  is  also  possible  to execute the ADB requests for each
-occurrence of the breakpoint but only stop after  the  third
-occurrence by typing:
-          **getc+4,3:b  main.c?C**   (*
-This request will print the local variable ''c'' in the function
-''main'' at each occurrence of the breakpoint.  The semicolon is
-used to separate multiple ADB requests on a single line.
-
-Warning:  setting  a breakpoint causes the value of dot
-to be changed; executing the  program  under  ADB  does  not
-change dot.  Therefore:
-          **settab+4:b  .,5?ia**
------------
-(* Owing to a bug in early versions of ADB (including
-the  version  distributed  in Generic 3 UNIX)
-these statements must be written as:
-          **settab+4:b     settab,5?ia;0**
-          **getc+4,3:b     main.c?C;0**
-          **settab+4:b     settab,5?ia; ptab/o;0**
-Note that **;0** will set dot to zero and stop at  the
-breakpoint.
-
-          **fopen+4:b**
-will  print  the  last  thing dot was set to (in the example
-''fopen+4'') ''not'' the current location (''settab+4'')  at  which  the
-program is executing.
-
-A  breakpoint can be overwritten without first deleting
-the old breakpoint.  For example:
-          **settab+4:b  settab,5?ia; ptab/o**  (*
-could be entered after typing the above requests.
-
-Now the display of breakpoints:
-          **$b**
-shows the above request for the ''settab'' breakpoint.  When the
-breakpoint  at  ''settab''  is  encountered the ADB requests are
-executed.  Note that  the  location  at  ''settab+4''  has  been
-changed  to  plant  the  breakpoint; all the other locations
-match their original value.
-
-Using the functions, ''f,'' ''g'' and ''h'' shown in Figure  3,  we
-can  follow  the execution of each function by planting non-stopping
-breakpoints.  We call ADB with the executable  program
-of Figure 3 as follows:
-          **adb ex3 -**
-Suppose we enter the following breakpoints:
-          **h+4:b  hcnt/d;  h.hi/;  h.hr/**
-          **g+4:b  gcnt/d;  g.gi/;  g.gr/**
-          **f+4:b  fcnt/d;  f.fi/;  f.fr/**
-          **:r**
-Each  request  line indicates that the variables are printed
-in decimal (by the specification **d**).  Since  the  format  is
-not  changed,  the  **d**  can  be  left  off  all but the first
-request.
-
-The output in Figure 7 illustrates two points.   First,
-the  ADB  requests  in  the breakpoint line are not examined
-until the program under test is run.  That means any  errors
-in  those  ADB  requests is not detected until run time.  At
-the location of the error ADB stops running the program.
-
-The second point is the way ADB handles register  variables.
-ADB  uses  the  symbol  table to address variables.
-Register variables, like ''f.fr'' above, have pointers to uninitialized
-places on the stack.  Therefore the message "symbol
-not found".
-
-Another way of getting at the data in this  example  is
-to print the variables used in the call as:
-          **f+4:b  fcnt/d;  f.a/;  f.b/;  f.fi/**
-          **g+4:b  gcnt/d;  g.p/;  g.q/;  g.gi/**
-          **:c**
-The  operator  /  was used instead of ?  to read values from
-the ''core'' file.  The output for each function,  as  shown  in
-Figure  7,  has  the  same  format.  For the function ''f'', for
-example, it  shows  the  name  and  value  of  the  //external//
-variable  ''fcnt.''   It also shows the address on the stack and
-value of the variables //a,'' ''b'' and ''fi.//
-
-Notice that the addresses on the stack will continue to
-decrease  until  no address space is left for program execution
-at which time (after many pages of output) the  program
-under  test  aborts.  A display with names would be produced
-by requests like the following:
-          **f+4:b  fcnt/d;  f.a/"a="d;  f.b/"b="d;  f.fi/"fi="d**
-In this format the quoted string is  printed  literally  and
-the  **d**  produces  a  decimal  display of the variables.  The
-results are shown in Figure 7.
-
-==== 3.5. Other Breakpoint Facilities ====
-
-(*) Arguments and change of standard input  and  output  are
-passed to a program as:
-              **:r  arg1  arg2 ... <infile  >outfile**
-This  request  kills any existing program under test and
-starts the ''a.out'' afresh.
-
-(*) The program being debugged can be single stepped by:
-              **:s**
-If necessary, this request will  start  up  the  program
-being  debugged  and  stop  after  executing  the  first
-instruction.
-
-(*) ADB allows a program to be entered at a specific address
-by typing:
-              **address:r**
-
-(*) The  count  field can be used to skip the first ''n'' breakpoints as:
-              **,n:r**
-The request:
-              **,n:c**
-may also be used for skipping the  first  ''n''  breakpoints
-when continuing a program.
-
-
-(*) A  program can be continued at an address different from
-the breakpoint by:
-              **address:c**
-
-(*) The program being debugged runs as  a  separate  process
-and can be killed by:
-              **:k**
-
-
-===== 4. Maps =====
-
-UNIX  supports  several executable file formats.  These
-are used to tell the loader how to load  the  program  file.
-
-File  type  407  is  the most common and is generated by a C
-compiler invocation such as **cc pgm.c**.  A 410  file  is  produced
-by  a  C  compiler  command  of the form **cc -n pgm.c**,
-whereas a 411 file is produced by **cc -i pgm.c**.   ADB  interprets
-these  different  file formats and provides access to
-the different segments through a set of maps (see Figure 8).
-To print the maps type:
-          **$m**
-
-In  407  files,  both  text (instructions) and data are
-intermixed.  This makes it impossible for ADB to differentiate
-data from instructions and some of the printed symbolic
-addresses  look  incorrect;  for  example,   printing   data
-addresses as offsets from routines.
-
-In  410 files (shared text), the instructions are separated
-from data and **?* ** accesses the data part of  the  ''a.out**
-file.   The  **?* ** request tells ADB to use the second part of
-the map in the ''a.out'' file.  Accessing data in the ''core''  file
-shows the data after it was modified by the execution of the
-program.  Notice also that the data segment may  have  grown
-during program execution.
-
-In  411 files (separated I & D space), the instructions
-and data are also separated.  However, in this  case,  since
-data is mapped through a separate set of segmentation registers,
-the base of the  data  segment  is  also  relative  to
-address  zero.   In this case since the addresses overlap it
-is necessary to use the **?* ** operator to access the data space
-of  the  ''a.out''  file.   In both 410 and 411 files the corresponding
-core file does not contain the program text.
-
-Figure 9 shows the display of three maps for  the  same
-program  linked  as a 407, 410, 411 respectively.  The b, e,
-and f fields are used by ADB  to  map  addresses  into  file
-addresses.   The  "f1"  field is the length of the header at
-the beginning of the file (020 bytes for an ''a.out''  file  and
-02000  bytes  for  a ''core'' file).  The "f2" field is the displacement
-from the beginning of the file to the data.  For a
-407  file  with  mixed text and data this is the same as the
-length of the header; for 410 and  411  files  this  is  the
-length of the header plus the size of the text portion.
-
-The  "b"  and  "e"  fields  are the starting and ending
-locations for a segment.  Given an address, A, the  location
-in the file (either ''a.out'' or ''core'') is calculated as:
-          **b1<=A<=e1 => file address = (A-b1)+f1**
-          **b2<=A<=e2 => file address = (A-b2)+f2**
-A  user  can access locations by using the ADB defined variables.
-The **$v** request prints the variables  initialized  by
-ADB:
-
-|| b || base address of data segment ||
-|| d || length of the data segment ||
-|| s || length of the stack ||
-|| t || length of the text ||
-|| m || execution type (407,410,411) ||
-
-In  Figure 9 those variables not present are zero.  Use
-can be made of these variables by expressions such as:
-          **<b**
-in the address field.  Similarly the value of  the  variable
-can be changed by an assignment request such as:
-          **02000>b**
-that  sets  **b**  to octal 2000.  These variables are useful to
-know if the file under examination is an executable or  //core//
-image file.
-
-ADB reads the header of the ''core'' image file to find the
-values for these variables.  If the  second  file  specified
-does  not  seem  to be a ''core'' file, or if it is missing then
-the header of the executable file is used instead.
-
-
-===== 5. Advanced Usage =====
-
-It is possible with ADB to combine formatting  requests
-to provide elaborate displays.  Below are several examples.
-
-==== 5.1. Formatted dump ====
-
-The line:
-          **<b,-1/4o4^8Cn**
-prints  4 octal words followed by their ASCII interpretation
-from the data space of the core image  file.   Broken  down,
-the various request pieces mean:
-
-|| <b    || The base address of the data segment. ||
-|| <b,-1 || Print  from  the base address to the end of file.  A negative count is  used  here  and elsewhere  to  loop  indefinitely  or until some error condition (like end of file)  is detected. ||
-
-The format **4o4^8Cn** is broken down as follows:
-
-|| 4o || Print 4 octal locations. ||
-|| 4^ || Backup  the current address 4 locations (to the original start of the field). ||
-|| 8C || Print 8  consecutive  characters  using  an escape  convention;  each  character in the range 0 to 037 is printed as @ followed  by the  corresponding  character  in the range  0140 to 0177.  An @ is printed as @@. ||
-|| n  || Print a newline. ||
-
-The request:
-          **<b,<d/4o4^8Cn**
-could have been used instead to allow the printing  to  stop
-at the end of the data segment (<d provides the data segment
-size in bytes).
-
-The formatting requests  can  be  combined  with  ADB's
-ability  to  read  in  a script to produce a core image dump
-script.  ADB is invoked as:
-          **adb a.out core < dump**
-to read in a script file, ''dump,'' of requests.  An example  of
-such a script is:
-          **120$w**
-          **4095$s**
-          **$v**
-          **=3n**
-          **$m**
-          **=3n"C Stack Backtrace"**
-          **$C**
-          **=3n"C External Variables"**
-          **$e**
-          **=3n"Registers"**
-          **$r**
-          **0$s**
-          **=3n"Data Segment"**
-          **<b,-1/8ona**
-
-The  request  **120$w** sets the width of the output to 120
-characters (normally, the  width  is  80  characters).   ADB
-attempts to print addresses as:
-          **symbol + offset**
-The  request **4095$s** increases the maximum permissible offset
-to the nearest symbolic address from 255 (default) to  4095.
-The  request  **=** can be used to print literal strings.  Thus,
-headings are provided in this ''dump'' program with requests  of
-the form:
-          **=3n"C Stack Backtrace"**
-that  spaces three lines and prints the literal string.  The
-request **$v** prints all non-zero ADB variables (see Figure 8).
-The  request  **0$s** sets the maximum offset for symbol matches
-to zero thus suppressing the printing of symbolic labels  in
-favor  of octal values.  Note that this is only done for the
-printing of the data segment.  The request:
-          **<b,-1/8ona**
-prints a dump from the base of the data segment to  the  end
-of  file with an octal address field and eight octal numbers
-per line.
-
-Figure 11 shows the results of some formatting requests
-on the C program of Figure 10.
-
-==== 5.2. Directory Dump ====
-
-As  another  illustration (Figure 12) consider a set of
-requests to dump the contents of a directory (which is  made
-up of an integer ''inumber'' followed by a 14 character name):
-          **adb dir -**
-          **=n8t"Inum"8t"Name"**
-          **0,-1? u8t14cn**
-In  this  example,  the  **u** prints the ''inumber'' as an unsigned
-decimal integer, the **8t** means that ADB  will  space  to  the
-next  multiple  of  8 on the output line, and the **14c** prints
-the 14 character file name.
-
-==== 5.3. Ilist Dump ====
-
-Similarly the contents of the ''ilist'' of a  file  system,
-(e.g. /dev/src, on UNIX systems distributed by the UNIX Support
-Group; see UNIX Programmer's Manual Section V) could be
-dumped with the following set of requests:
-          **adb /dev/src -**
-          **02000>b**
-          **?m <b**
-          **<b,-1?"flags"8ton"links,uid,gid"8t3bn",size"8tbrdn"addr"8t8un"times"8t2Y2na**
-In  this  example  the  value  of  the  base for the map was
-changed to 02000 (by saying **?m<b**) since that is the start of
-an  ''ilist'' within a file system.  An artifice (**brd** above) was
-used to print the 24 bit size field as a byte, a space,  and
-a  decimal  integer.   The  last access time and last modify
-time are printed with the **2Y** operator.  Figure 12 shows portions
-of  these requests as applied to a directory and file
-system.
-
-==== 5.4. Converting values ====
-
-ADB may be used to convert values from one  representation
-to another.  For example:
-          **072 = odx**
-will print
-          **072    58      #3a**
-which  is the octal, decimal and hexadecimal representations
-of 072 (octal).  The format is  remembered  so  that  typing
-subsequent  numbers  will  print  them in the given formats.
-Character values may be converted similarly, for example:
-          **'a' = co**
-prints
-          **a      0141**
-It may also be used to evaluate expressions  but  be  warned
-that  all binary operators have the same precedence which is
-lower than that for unary operators.
-
-
-===== 6. Patching =====
-
-Patching files with ADB is accomplished with the //write,// **w**  or  **W**,
-request  (which  is  not like the ''ed'' editor write
-command).  This  is  often  used  in  conjunction  with  the
-''locate,''  **l** or **L** request.  In general, the request syntax
-for **l** and **w** are similar as follows:
-          **?l value**
-The request **l** is used to match on two bytes, **L** is  used  for
-four  bytes.   The  request  **w**  is  used to write two bytes,
-whereas **W** writes four bytes.   The  **value**  field  in  either
-''locate'' or ''write'' requests is an expression.  Therefore, decimal
-and octal numbers, or character strings are supported.
-
-In order to modify a file, ADB must be called as:
-          **adb -w file1 file2**
-When called with this option, ''file1'' and ''file2'' are created if
-necessary and opened for both reading and writing.
-
-For example, consider the C program shown in Figure 10.
-We can change the word "This" to "The "  in  the  executable
-file for this program, ''ex7'', by using the following requests:
-          **adb -w ex7 -**
-          **?l 'Th'**
-          **?W 'The '**
-The request **?l** starts at dot and stops at the first match of
-"Th" having set dot to the address of  the  location  found.
-Note  the  use of **?** to write to the ''a.out'' file.  The form **?* **
-would have been used for a 411 file.
-
-More frequently the request will be typed as:
-          **?l 'Th'; ?s**
-and locates the first  occurrence  of  "Th"  and  print  the
-entire  string.   Execution of this ADB request will set dot
-to the address of the "Th" characters.
-
-As another example  of  the  utility  of  the  patching
-facility,  consider  a  C program that has an internal logic
-flag.  The flag could be set by the user through ADB and the
-program run.  For example:
-          **adb a.out -**
-          **:s arg1 arg2**
-          **flag/w 1**
-          **:c**
-The  **:s**  request  is  normally used to single step through a
-process or start a process in single  step  mode.   In  this
-case it starts ''a.out'' as a subprocess with arguments **arg1** and **arg2**.
-If there is a subprocess running  ADB  writes  to  it
-rather  than  to the file so the **w** request causes ''flag'' to be
-changed in the memory of the subprocess.
-
-
-===== 7. Anomalies =====
-
-Below is a list  of  some  strange  things  that  users
-should be aware of.
-
-  - Function  calls  and  arguments are put on the stack by the C save routine.  Putting breakpoints at  the  entry point  to  routines means that the function appears not to have been called when the breakpoint occurs.
-
-  - When printing addresses, ADB uses either text  or  data symbols  from  the  ''a.out''  file.  This sometimes causes unexpected symbol names to be printed with  data  (e.g. ''savr5+022'').  This does not happen if **?** is used for text (instructions) and **/** for data.
-
-  - ADB cannot handle C  register  variables  in  the  most recently activated function.

-The authors are grateful for the thoughtful comments on
-how to organize this document from R. B. Brandt, E. N.  Pinson
-and B. A. Tague.  D. M. Ritchie made the system changes
-necessary to accommodate tracing within ADB. He also participated
-in  discussions during the writing of ADB.  His earlier
-work with DB and CDB led to many of the features  found in ADB.
