FCOMPILE-FILE

       &key output-file (load nil) (message-file nil) 
       ;GCL specific keywords:
       system-p c-debug c-file h-file data-file)

Compiles the file specified by INPUT-PATHNAME and generates a fasl file
specified by OUTPUT-FILE.  If the filetype is not specified in INPUT-PATHNAME,
then ".lsp" is used as the default file type for the source file.  :LOAD
specifies whether to load the generated fasl file after compilation.
:MESSAGE-FILE specifies the log file for the compiler messages.  It defaults to
the value of the variable COMPILER:*DEFAULT-MESSAGE-FILE*.  A non-NIL value of
COMPILER::*COMPILE-PRINT* forces the compiler to indicate the form currently
being compiled.  More keyword parameters are accepted, depending on the
version.  Most versions of GCL can receive :O-FILE, :C-FILE, :H-FILE, and
:DATA-FILE keyword parameters, with which you can control the intermediate
files generated by the GCL compiler.  Also :C-DEBUG will pass the -g flag to
the C compiler.


By top level forms in a file, we mean the value of *top-level-forms* after
doing (TF form) for each form read from a file.  We define TF as follows:

(defun TF (x)
 (when (consp x)
  (setq x (macroexpand x))
  (when (consp x)
     (cond ((member (car x) '(progn  eval-when))
            (mapcar 'tf (cdr x)))
           (t  (push x *top-level-forms*))))))

Among the common lisp special forms only DEFUN and DEFMACRO will cause actual
native machine code to be generated.  The rest will be specially treated in an
init section of the .data file.  This is done so that things like putprop,setq,
and many other forms would use up space which could not be usefully freed, if
we were to compile to native machine code.  If you have other `ordinary' top
level forms which you need to have compiled fully to machine code you may
either set compiler::*COMPILE-ORDINARIES* to t, or put them inside a

(PROGN 'COMPILE ...forms-which-need-to-be-compiled)

The compiler will take each of them and make a temporary function which will be
compiled and invoked once.  It is permissible to wrap a (PROGN 'COMPILE ..)
around the whole file.  Currently this construction binds the
compiler::*COMPILE-ORDINARIES* flag to t.  Setting this flag globally to a non
nil value to cause all top level forms to generate machine code.  This might be
useful in a system such as PCL, where a number of top level lambda expressions
are given.  Note that most common lisps will simply ignore the top level atom
'compile, since it has no side effects.

Defentry, clines, and defcfun also result in machine code being generated.

Evaluation at Compile time:
--------------------------
  In GCL the eval-when behaviour was changed in order to allow
more efficient init code, and also to bring it into line with the resolution
passed by the X3j13 committee.  Evaluation at compile time is controlled by
placing eval-when special forms in the code, or by the value of the variable
compiler::*eval-when-defaults* [default value :defaults].  If that variable
has value :defaults, then the following hold:

Eval at Compile       Type of Top Level Form

Partial: 	  defstructs, defvar, defparameter
Full:	          defmacro, defconstant, defsetf, define-setf-method,
			deftype, package ops, proclaim
None:             defun, others


By `partial' we mean (see the X3J13 Common Lisp document
(doc/compile-file-handling-of-top-level-forms) for more detail), that functions
will not be defined, values will not be set, but other miscellaneous compiler
properties will be set: eg properties to inline expand defstruct accessors and
testers, defstruct properties allowing subsequent defstructs to include this
one, any type hierarch information, special variable information will be set up.

Example:
(defun foo () 3)
(defstruct jo a b)

As a side effect of compiling these two forms, foo would not have its function
cell changed.  Neither would jo-a, although it would gain a property which
allows it to expand inline to a structure access.  Thus if it had a previous
definition (as commonly happens from previously loading the file), this previous
definition would not be touched, and could well be inconsistent with the
compiler properties.  Unfortunately this is what the CL standard says to do,
and I am just trying to follow it.

If you prefer a more intuitive scheme, of evaling all forms in the file, so
that there are no inconsistencies, (previous behaviour of AKCL) you may set
compiler::*eval-when-defaults* to '(compile eval load).

The variable compiler::*FASD-DATA* [default t] controls whether an ascii output
is used for the data section of the object file.  The data section will be in
ascii if *fasd-data* is nil or if the system-p keyword is supplied to
compile-file and *fasd-data* is not eq to :system-p.

The old GCL variable *compile-time-too* has disappeared.

(integer -3 10) --> signed-char
si::best-array-element-type is the function doing this.  It
is also used by the compiler, for coercing array element types.
If you are going to declare an array you should use the same
element type as was used in making it.  eg
(setq my-array (make-array 4 :element-type '(integer 0 10)))
(the (array (integer 0 10)) my-array)
    When wanting to optimize references to an array you need to
declare the array eg: (the (array (integer -3 10)) my-array) if ar
were constructed using the (integer -3 10) element-type.  You could of
course have used signed-char, but since the ranges may be
implementation dependent it is better to use -3 10 range.  MAKE-ARRAY
needs to do some calculation with the element-type if you don't
provide a primitive data-type.  One way of doing this in a machine
independent fashion:

  (defvar *my-elt-type* #.
      (array-element-type (make-array 1 :element-type '(integer -3 10))))

Then calls to (make-array n :element-type *my-elt-type*) will not have to go
through a type inclusion computation.  The keyword STATIC (KCL specific) if non
nil, will cause the array body to be non relocatable.

FREAD-LINE
Function in LISP package:
Args: (&optional (stream *standard-input*) (eof-error-p t)
                 (eof-value nil) (recursive-p nil))
Returns a line of text read from STREAM as a string, discarding the newline
character.

Note that when using line at a time input under unix,
input forms will always be followed by a #\newline.   Thus if you
do

>(read-line)
""
nil

the empty string will be returned.  After lisp reads the (read-line)
it then invokes (read-line).  This happens before it does anything
else and so happens before the newline character immediately following
(read-line) has been read.  Thus read-line immediately encounters a
#\newline and so returns the empty string.  If there had been other
characters before the #\newline it would have been different:

>(read-line) how are you
" how are you"
nil

If you want to throw away "" input, you can do that with
the following:

(sloop::sloop while (equal (setq input (read-line)) ""))

You may also want to use character at a time input, but that
makes input editing harder.

FDEFENTRY
Macro in LISP package:
Syntax: (defentry name arg-types c-function)

KCL specific: The compiler defines a Lisp function whose body consists of a
calling sequence to the C language function specified by C-FUNCTION.  The
interpreter ignores this form.  The ARG-TYPES specifies the C types of the
arguments which C-FUNCTION requires.  The list of allowed types is (object
char int float double string).  Code will be produced to coerce from a lisp
object to the appropriate type before passing the argument to the C-FUNCTION.
The c-function should be of the form (c-result-type c-fname) where
c-result-type is a member of (void object char int float double string).
c-fname may be a symbol (in which case it will be downcased) or a string.  If
c-function is not a list, then (object c-function) is assumed.

  Sample usage:
--File begin-----
;; JOE takes X a lisp string and Y a fixnum and returns a character.
(clines "#include \"foo.ch\"")
(defentry joe (string int) (char "our_c_fun"))
---File end------

             all symbols which are similarly declared for currently
             traced functions.  Each form  is evaluated immediately.
                                         i
             Upon any invocation of a traced function when not already
             inside a traced function call, each var  is bound to
                                                    i
             that value of form .
                               i
:COND            DEFAULT: T
               Here, FORM is any Lisp form to be evaluated (by EVAL)
             upon entering a call of FN, in the environment where si::ARGLIST
             is bound to the current list of arguments of FN.  Note that
             even if the evaluation of FORM changes the value of SI::ARGLIST
             (e.g. by evaluation of (SETQ si::ARGLIST ...)), the list of
             arguments passed to FN is unchanged.  Users may alter args passed
	     by destructively modifying the list structure of SI::ARGLIST
	     however. The call is traced 
             (thus invoking the :ENTRYCOND and :EXITCOND forms, at least)
             if and only if FORM does not evaluate to NIL.

:ENTRYCOND       DEFAULT: T
               This is evaluated (by EVAL) if the :COND form evaluates to
             non-NIL, both in an environment where SI::ARGLIST is bound to the
             current list of arguments of FN.  If non-NIL, the :ENTRY form
             is then evaluated and printed with the trace "prompt".

:ENTRY           DEFAULT: (CONS (QUOTE x) SI::ARGLIST),
                           where x is the symbol we call FN
               If the :COND and :ENTRYCOND forms evaluate to non-NIL,
             then the trace "prompt" is printed and then this FORM is
             evaluated (by EVAL) in an environment where SI::ARGLIST is bound
             to the current list of arguments of FN.  The result is then
             printed.

:EXITCOND        DEFAULT: T
               This is evaluated (by EVAL) in the environment described
             below for the :EXIT form.  The :EXIT form is then evaluated
             and printed with the "prompt" if and only if the result here
             is non-NIL.

:EXIT            DEFAULT: (CONS (QUOTE x) VALUES),
                          where x is the symbol we call FN
               Upon exit from tracing a given call, this FORM is
             evaluated (after the appropriate trace "prompt" is printed),
             using EVAL in an environment where SI::ARGLIST is bound to the
             current list of arguments of FN and VALUES is bound to the
             list of values returned by FN (recalling that Common Lisp
             functions may return multiple values).

:DEPTH           DEFAULT:  No depth limit
               FORM is simply a positive integer specifying the maximum
             nesting of traced calls of FN, i.e. of calls of FN in which
             the :COND form evaluated to non-NIL.  For calls of FN in
             which this limit is exceeded, even the :COND form is not
             evaluated, and the call is not traced.
FDEFCONSTANT

FFORMAT
Function in LISP package:
Args: (destination control-string &rest arguments)
Provides various facilities for formatting output.
DESTINATION controls where the result will go.  If DESTINATION is T, then
the output is sent to the standard output stream.  If it is NIL, then the
output is returned in a string as the value of the call.  Otherwise,
DESTINATION must be a stream to which the output will be sent.

CONTROL-STRING is a string to be output, possibly with embedded
formatting directives, which are flagged with the escape character
"~".  Directives generally expand into additional text to be output,
usually consuming one or more of ARGUMENTs in the process.



A few useful directives are:

~A, ~nA, ~n@A	Prints one argument as if by PRINC
~S, ~nS, ~n@S	Prints one argument as if by PRIN1
~D, ~B, ~O, ~X	Prints one integer in decimal, binary, octal, and hexa
~%		Does TERPRI
~&		Does FRESH-LINE

where n is the minimal width of the field in which the object is printed.
~nA and ~nS put padding spaces on the right; ~n@A and ~n@S put on the left.

~R  is for printing numbers in various formats.

  ~nR   prints arg in radix n.
  ~R    prints arg as a cardinal english number: two
  ~:R   prints arg as an ordinal english number: third
  ~@R   prints arg as an a Roman Numeral: VII
  ~:@R   prints arg as an old Roman Numeral: IIII

~C prints a character.
  ~:C represents non printing characters by their pretty names,eg Space
  ~@C uses the #\ syntax to allow the reader to read it.

~F prints a floating point number arg.
  The full form is ~w,d,k,overflowchar,padcharF
  w represents the total width of the printed representation (variable if
    not present)
  d the number of fractional digits to display
    (format nil "~,2f" 10010.0314) --> "10010.03"
  k arg is multiplied by 10^k before printing it as a decimal number.
  overflowchar width w characters copies of the overflow character will
    be printed.   eg(format t "X>~5,2,,'?F<X" 100.034) --> X>?????<X
  padchar is the character to pad with
    (format t "X>~10,2,1,'?,'bF<X" 100.03417) -->X>bbb1000.34<X
  @ makes + sign print if the arg is positive

~@[print-if-true~]
   if arg is not nil, then it is retained as an arg for further printing,
   otherwise it is used up 
   (format nil "~@[x = ~d~]~a" nil 'bil) --> "BIL"
   (format nil "~@[x = ~d ~]~a" 8) --> "x = 8 BIL"


FASSERT
Macro in LISP package:

symbol '*', but not to NIL.  When the type system of KCL encounters a
type specifier (NAME arg1 ... argn), it calls the expansion function with
the arguments arg1 ... argn, and uses the returned value instead of the
original type specifier.  When the symbol NAME is used as a type specifier,
the expansion function is called with no argument.  The doc-string DOC, if

Returns the tail of LIST beginning with the first ITEM.

FSTRING-LESSP
Function in LISP package:
Args: (string1 string2
       &key (start1 0) (end1 (length string1))
            (start2 0) (end2 (length string2)))
Similar to STRING<, but ignores cases.

FRANDOM
Function in LISP package:
Args: (number &optional (state *random-state*))
Generates a uniformly distributed pseudo-random number between zero
(inclusive) and NUMBER (exclusive), by using the random state object STATE.

Args: (i)
KCL specific: Returns the symbol of the i-th entity in the bind stack.

FERROR-SET
Function in SI package:
Args: (form)
KCL specific: Evaluates the FORM in the null environment.  If the evaluation
of the FORM has successfully completed, SI:ERROR-SET returns NIL as the first
value and the result of the evaluation as the rest of the values.  If, in the
course of the evaluation, a non-local jump from the FORM is atempted,
SI:ERROR-SET traps the jump and returns the corresponding jump tag as its
value.

FCOMPILED-FUNCTION-NAME
Function in SI package:
Args: (compiled-function-object)
KCL specific: Returns the name of the COMPILED-FUNCTION-OBJECT.

FSTRUCTUREP
Function in SI package:

FIHS-VS
Function in SI package:
Args: (i)
KCL specific: Returns the value stack index of the i-th entity in the
invocation history stack.

FUNIVERSAL-ERROR-HANDLER
Function in SI package:
Args: (error-name correctable function-name
       continue-format-string error-format-string
       &rest args)
KCL specific: Starts the error handler of KCL.  When an error is detected,
KCL calls SI:UNIVERSAL-ERROR-HANDLER with the specified arguments.
ERROR-NAME is the name of the error.  CORRECTABLE is T for a correctable
error and NIL for a fatal error.  FUNCTION-NAME is the name of the function
that caused the error.  CONTINUE-FORMAT-STRING and ERROR-FORMAT-STRING are
the format strings of the error message.  ARGS are the arguments to the
format strings.
     To change the error handler of KCL, redefine SI:UNIVERSAL-ERROR-
HANDLER.

V*INTERRUPT-ENABLE*
Variable in SI package:
KCL specific: If the value of SI:*INTERRUPT-ENABLE* is non-NIL, KCL signals
an error on the terminal interrupt (this is the default case).  If it is NIL,
KCL ignores the interrupt and assigns T to SI:*INTERRUPT-ENABLE*.

FCHDIR
Function in SI package:
Args: (pathname)
KCL/UNIX specific: Changes the current working directory to the specified
pathname.

FCOPY-STREAM
Function in SI package:
Args: (in-stream out-stream)
KCL specific: Copies IN-STREAM to OUT-STREAM until the end-of-file on IN-
STREAM.

FINIT-SYSTEM
Function in SI package:
Args: ()
KCL specific: Initializes the library and the compiler of KCL.  Since they
have already been initialized in the standard image of KCL, calling SI:INIT-
SYSTEM will cause an error.

V*INDENT-FORMATTED-OUTPUT*
Variable in SI package:
KCL specific: The FORMAT directive ~% indents the next line if the value of
this variable is non-NIL.  If NIL, ~% simply does Newline.

FSET-HOLE-SIZE
Function in SI package:
Args: (fixnum)
KCL specific: Sets the size of the memory hole (in pages).

FFRS-BDS
Function in SI package:
Args: (i)
KCL specific: Returns the bind stack index of the i-th entity in the frame
stack.

FIHS-FUN
Function in SI package:
Args: (i)
KCL specific: Returns the function value of the i-th entity in the invocation
history stack.

F*MAKE-CONSTANT
Function in SI package:
Args: (symbol value)
KCL specific: Makes the SYMBOL a constant with the specified VALUE.

FFIXNUMP
Function in SI package:
Args: (object)
KCL specific: Returns T if the OBJECT is a fixnum; NIL otherwise.

FBDS-VAL
Function in SI package:
Args: (i)
KCL specific: Returns the value of the i-th entity in the bind stack.

FSTRING-TO-OBJECT
Function in SI package:
Args: (string)
KCL specific: (SI:STRING-TO-OBJECT STRING) is equivalent to
(READ-FROM-STRING STRING), but much faster.

V*SYSTEM-DIRECTORY*
Variable in SI package:
KCL specific: Holds the name of the system directory of KCL.

FFRS-IHS
Function in SI package:
Args: (i)
KCL specific: Returns the invocation history stack index of the i-th entity
in the frame stack.

FRESET-GBC-COUNT
Function in SI package:
Args: ()
KCL specific: Resets the counter of the garbage collector that records how
many times the garbage collector has been called for each implementation
type.

FCATCH-BAD-SIGNALS
Function in SI package:
Args: ()
KCL/BSD specific: Installs a signal catcher for bad signals:
	SIGILL, SIGIOT, SIGEMT, SIGBUS, SIGSEGV, SIGSYS.
The signal catcher, upon catching the signal, signals an error (and enter
the break-level).  Since the internal memory of KCL may be broken, the user
should check the signal and exit from KCL if necessary.  When the signal
is caught during garbage collection, KCL terminates immediately.

FRESET-STACK-LIMITS
Function in SI package:
Args: ()
KCL specific: Resets the stack limits to the normal state.  When a stack has
overflowed, KCL extends the limit for the stack in order to execute the error
handler.  After processing the error, KCL resets the stack limit by calling
SI:RESET-STACK-LIMITS.

V*GBC-MESSAGE*
Variable in SI package:
KCL specific: If the value of SI:*GBC-MESSAGE* is non-NIL, the garbage
collector prints some information on the terminal.  Usually SI:*GBC-MESSAGE*
should be set NIL.

F*MAKE-SPECIAL
Function in SI package:
Args: (symbol)
KCL specific: Makes the SYMBOL globally special.

FMAKE-STRING-OUTPUT-STREAM-FROM-STRING
Function in SI package:
Args: (string)
KCL specific: Creates a string-output-stream corresponding to the STRING and
returns it.  The STRING should have a fill-pointer.

V*IGNORE-EOF-ON-TERMINAL-IO*
Variable in SI package:
KCL specific: If the value of SI:*IGNORE-EOF-ON-TERMINAL-IO* is non-NIL, KCL
ignores the eof-character (usually ^D) on the terminal and the terminal never
becomes end-of-file.  The default value of SI:*IGNORE-EOF-ON-TERMINAL-IO* is
NIL.

FADDRESS
Function in SI package:
Args: (object)
KCL specific: Returns the address of the OBJECT as a fixnum.  The address of
an object depends on the version of KCL.  E.g. (SI:ADDRESS NIL) returns
1879062044 on KCL/AOSVS dated March 14, 1986.

V*LISP-MAXPAGES*
Variable in SI package:
KCL specific: Holds the maximum number of pages (1 page = 2048 bytes) for the
KCL process.  The result of changing the value of SI:*LISP-MAXPAGES* is
unpredictable.

FARGC
Function in SI package:
Args: ()
KCL specific: Returns the number of arguments on the command line that invoked
the KCL process.

FNANI
Function in SI package:
Args: (fixnum)
KCL specific: Returns the object in the address FIXNUM.  This function is
the inverse of SI:ADDRESS.  Although SI:ADDRESS is a harmless operation,
SI:NANI is quite dangerous and should be used with care.

V*NOTIFY-GBC*
Variable in SI package:
KCL specific: If the value of this variable is non-NIL, then the garbage
collector notifies that it begins to run whenever it is invoked.  Otherwise,
garbage collection begins silently.

FSAVE-SYSTEM
Function in SI package:
Args: (pathname)
KCL specific: Saves the current KCL core imange into a program file specified
by PATHNAME.  This function differs from SAVE in that the contiguous and
relocatable areas are made permanent in the saved image.  Usually the
standard image of KCL interpreter/compiler is saved by SI:SAVE-SYSTEM.
This function causes an exit from lisp.  Various changes are made
to the memory of the running system, such as closing files and
resetting io streams.   It would not be possible to continue normally.   

FUNCATCH-BAD-SIGNALS
Function in SI package:
Args: ()
KCL/BSD specific: Undoes the effect of SI:CATCH-BAD-SIGNALS.

FVS
Function in SI package:
Args: (i)
KCL specific: Returns the i-th entity in the value stack.

FDISPLACED-ARRAY-P
Function in SI package:
Args: (array)
KCL specific: Returns T if the ARRAY is a displaced array; NIL otherwise.

FARGV
Function in SI package:
Args: (fixnum)
KCL specific: Returns the FIXNUM-th argument on the command line that invoked
the KCL process.

V*DEFAULT-TIME-ZONE*
Variable in SI package:
KCL specific: Holds the default time zone.  The initial value of SI:*DEFAULT-
TIME-ZONE* is -9 (the time zone of Japan).

FGETENV
Function in SI package:
Args: (string)
KCL/UNIX specific: Returns the environment with the name STRING as a string;
if the environment specified by STRING is not found, returns NIL.

FFASLINK
Function in SI package:
Args: (file string)
KCL/BSD specific: Loads the FASL file FILE while linking the object files and
libraries specified by STRING.  For example,
	(faslink "foo.o" "bar.o boo.o -lpixrect")
loads foo.o while linking two object files (bar.o and boo.o) and the library
pixrect.  Usually, foo.o consists of the C language interface for the
functions defined in the object files or the libraries.

A more portable way of making references to C code, is to build it
in at the time of the original make.   If foo.c references things
in -lpixrect, and foo.o is its compilation in the gcl/unixport directory

(cd gcl/unixport ; make "EXTRAS= foo.o -lpixrect ")

should add them.   If EXTRAS was already joe.o in the unixport/makefile
you should of course add joe.o to the above "EXTRAS= joe.o foo.o.."

Faslink does not work on most UNIX systems which are derived from SYS V or AIX.



FTOP-LEVEL
Function in SI package:
Args: ()
KCL specific: Starts the standard top-level listner of KCL.  When the KCL
process is invoked, it calls SI:TOP-LEVEL by (FUNCALL 'SI:TOP-LEVEL).
     To change the top-level of KCL, redefine SI:TOP-LEVEL and save the core
imange in a file.  When the saved imange is invoked, it will start the
redefined top-level.

FFRS-VS
Function in SI package:
Args: (i)
KCL specific: Returns the value stack index of the i-th entity in the frame
stack.

FUSE-FAST-LINKS
Function in LISP package:
Args: (turn-on)
GCL specific: If TURN-ON is not nil, the fast link mechanism is enabled,
so that ordinary function calls will not appear in the invocation stack,
and calls will be much faster.  This is the default.   If you anticipate
needing to see a stack trace in the debugger, then you should turn this
off.

FWRITE-DEBUG-SYMBOLS
Function in the SI package:
Args: (start file
  &key (main-file "/usr/local/schelter/xkcl/unixport/raw_kcl")
  (output-file "debug-symbols.o" ))
Write out a file of debug-symbols using address START as the place
where FILE will be loaded into the running executable MAIN-FILE.  The
last is a keyword argument.



FPROF
Function in the SI package:
Args: (x y)
These functions in the SI package are GCL specific, and allow monitoring
the run time of functions loaded into GCL, as well as the basic functions.
 Sample Usage:
    (si::set-up-profile 1000000) (si::prof 0 90)
     run program
    (si::prof 0 0)   ;; turn off profile
    (si::display-prof)
    (si::clear)
    (si::prof 0 90)  ;; start profile again
    run program
   ..
  Profile can be stopped with (si::prof 0 0) and restarted with (si::prof 0 90)
The START-ADDRESS will correspond to the beginning of the profile array, and
the SCALE will mean that 256 bytes of code correspond to SCALE bytes in the
profile array.

Thus if the profile array is 1,000,000  bytes long and the code segment is 
5 megabytes long you can profile the whole thing using a scale of 50
Note that long runs may result in overflow, and so an understating of the
time in a function.

You must run intensively however since, with a scale of 128 it takes
6,000,000 times through a loop to overflow the sampling in one part of
the code.

FCATCH-FATAL
Function in the SI package:
Args: (i)

Sets the value of the C variable catch_fatal to I which should be an integer.
If catch_fatal is 1, then most unrecoverable fatal errors will be caught.
Upon catching such an error catch_fatal becomes -1, to avoid recursive errors.
The top level loop automatically sets catch_fatal to 1, if the value is less
than zero.  Catching can be turned off by making catch_fatal = 0.



V*MULTIPLY-STACKS*
Variable in SI package:

If this variable is set to a positive fixnum, then the next time through the
TOP-LEVEL loop, the loop will be exited.  The size of the stacks will be
multiplied by the value of *multiply-stacks*, and the TOP-LEVEL will be called
again.  Thus to double the size of the stacks:

>(setq si::*multiply-stacks* 2)
[exits top level and reinvokes it, with the new stacks in place]
>

We must exit TOP-LEVEL, because it and any other lisp functions
maintain many pointers into the stacks, which would be incorrect when the
stacks have been moved.    Interrupting the process of growing the stacks,
can leave you in an inconsistent state.

FEMIT-FN
Function in the COMPILER package:
Args: (turn-on)
If TURN-ON is t, the subsequent calls to  COMPILE-FILE will
cause compilation of foo.lisp to emit a foo.fn as well as foo.o.
The .fn file contains cross referencing information as well as
information useful to the collection utilities in cmpnew/collectfn
This latter file must be manually loaded to call emit-fn.

VDYNAMIC-EXTENT
Variable in the KEYWORD package:
Declaration to allow locals to be cons'd on the C stack.
For example
(defun foo (&rest l) (declare (:dynamic-extent l)) ...)
will cause l to be a list formed on the C stack of the foo function
frame.
Of course passing L out as a value of foo will cause havoc.
(setq x (make-list n))
(setq x (cons a b))
(setq x (list a  b c ..))
also are handled on the stack, for dynamic-extent x.


FGBC-TIME
Function in the SI package:
Args: (&optional x)
Sets the internal C variable gc_time to X if X is supplied and then
returns gc_time.  If gc_time is greater or equal to 0, then gc_time is
incremented by the garbage collector, according to the number of
internal time units spent there.   The initial value of gc_time is -1.


FFWRITE
Function in the SI package:
Args: (string start count stream)
Write from STRING starting at char START (or 0 if it is nil) COUNT characters
(or to end if COUNT is nil) to STREAM.  STREAM must be a stream such as
returned by FP-OUTPUT-STREAM.  Returns nil if it fails.


FFREAD
Function in the SI package:
Args: (string start count stream)
Read characters into STRING starting at char START (or 0 if it is nil) COUNT
characters (or from start to length of STRING if COUNT is nil).  Characters
are read from STREAM.  STREAM must be a stream such as returned by
FP-INPUT-STREAM.  Returns nil if it fails.  Return number of characters read
if it succeeds.

V*CMPINCLUDE-STRING*
Variable in the COMPILER package:
If it is a string it holds the text of the cmpinclude.h file appropriate for
this version.  Otherwise the usual #include of *cmpinclude* will be used.  To
disable this feature set *cmpinclude-string* to NIL in the init-form.

FEMIT-FN
Function in the COMPILER package:
Args: (turn-on)

If TURN-ON is t, then subsequent calls to compile-file on a file foo.lisp
cause output of a file foo.fn.  This .fn file contains lisp structures
describing the functions in foo.lisp.  Some tools for analyzing this data base
are WHO-CALLS, LIST-UNDEFINED-FUNCTIONS, LIST-UNCALLED-FUNCTIONS, and
MAKE-PROCLAIMS.

Usage:
(compiler::emit-fn t)
(compile-file "foo1.lisp")
(compile-file "foo2.lisp")

This would create foo1.fn and foo2.fn.  These may be loaded using LOAD.  Each
time compile-file is called the data base is cleared.  Immediately after the
compilation, the data base consists of data from the compilation.  Thus if you
wished to find functions called but not defined in the current file, you could
do (list-undefined-functions), immediately following the compilation.  If you
have a large system, you would load all the .fn files before using the above
tools.

FMAKE-ALL-PROCLAIMS
Function in the COMPILER package:
Args: (&rest directories)

For each D in DIRECTORIES all files in (directory D) are loaded.

For example 
(make-all-proclaims "lsp/*.fn" "cmpnew/*.fn")
would load any files in lsp/*.fn and cmpnew/*.fn.

[See EMIT-FN for details on creation of .fn files] 

Then calculations on the newly loaded .fn files are made, to determine
function proclamations.  If number of values of a function cannot be
determined [for example because of a final funcall, or call of a function
totally unknown at this time] then return type * is assigned.

Finally a file sys-proclaim.lisp is written out.  This file contains function
proclamations.

(load "sys-proclaim.lisp")
(compile-file "foo1.lisp")
(compile-file "foo2.lisp")



FMAKE-PROCLAIMS
Function in the COMPILER package:
Args: (&optional (stream *standard-output*))

Write to STREAM the function proclaims from the current data base.  Usually a
number of .fn files are loaded prior to running this.  See EMIT-FN for details
on how to collect this.  Simply use LOAD to load in .fn files.

FLIST-UNDEFINED-FUNCTIONS
Function in the COMPILER package:
Args: ()

Return a list of all functions called but not defined, in the current data
base (see EMIT-FN).

Sample:
(compiler::emit-fn t)
(compile-file "foo1.lisp")
(compiler::list-undefined-functions)
or
(mapcar 'load (directory "*.fn")) (compiler::list-undefined-functions)

FWHO-CALLS 
Function in the COMPILER package:
Args: (function-name)

List all functions in the data base [see emit-fn] which call FUNCTION-NAME.

FLIST-UNCALLED-FUNCTIONS
Function in the COMPILER package:
Args: ()

Examine the current data base [see emit-fn] for any functions or macros which
are called but are not: fboundp, OR defined in the data base, OR having
special compiler optimizer properties which would eliminate an actual call.



FSGC-ON
Function in the SI package:
Args: (&optional ON)
If ON is not nil then SGC (stratified garbage collection) is turned
on.   If ON is supplied and is nil, then SGC is turned off.
If ON is not supplied, then it returns T if SGC is on, and NIL if
SGC is off.

The purpose of SGC is to prevent paging activity during garbage
collection.  It is efficient if the actual number of pages being
written to form a small percentage of the total image size.  The image
should be built as compactly as possible.  This can be accomplished by
using a settings such as (si::allocate-growth 'cons 1 10 50) to limit
the growth in the cons maxpage to 10 pages per time.    Then
just before calling si::save-system to save your image you can
do something like:

(si::set-hole-size 500)(gbc nil) (si::sgc-on t) (si::save-system ..)

This makes the saved image come up with SGC on.  We have set a
reasonably large hole size.  This is so that allocation of pages
either because they fill up, or through specific calls to
si::allocate, will not need to move all the relocatable data.  Moving
relocatable data requires turning SGC off, performing a full gc, and
then turning it back on.  New relocatable data is collected by SGC,
but moving the old requires going through all pages of memory to
change pointers into it.

Using si::*notify-gbc* gives information about the number of pages
used by SGC.   

Note that SGC is only available on operating systems which provide
the mprotect system call, to write protect pages.   Otherwise we
cannot tell which pages have been written too.


FALLOCATE-SGC
Function in the SI package:
Args: (type min-pages max-pages percent-free)
If MIN-PAGES is 0, then this type will not be swept by SGC.    Otherwise
this is the minimum number of pages to make available to SGC.   MAX-PAGES
is the upper limit of such pages.   Only pages with PERCENT-FREE objects
on them, will be assigned to SGC.
A list of the previous values for min, max and percent are returned.

FALLOCATE-GROWTH
Function in the SI package:
Args: (type min max percent)
The next time after a GC for TYPE, if there are not sufficient objects
free, as a percent of all such objects, and if the maximum number of
pages for this type has already been allocated, then the maximum
number will be increased by PERCENT of the old maximum,
subject to the condition that this is at least MIN and at most MAX.
A list of the previous values for min, max and percent are returned.

Using (si::allocate-growth 'cons 1 10 50) would cause growth to be reasonably
slow.   This would be a reasonable setting during building of a large system
in order to pack the data together.   When running, a higher max and
percent might be useful.
FOPEN-FASD
Function in the SI package:
Args: (stream direction eof-value table)
Given file STREAM open for input or output in DIRECTION,
set it up to start writing or reading in fasd format.   When
reading from this stream the EOF-VALUE will be returned when
the end a fasd end of dump marker is encountered.   TABLE should
be an eq hashtable on output, a vector on input, or nil.   In this
last case a default one will be constructed.

We shall refer to the result as a `fasd stream'.   It is
suitable as the arg to CLOSE-FASD, READ-FASD-TOP, and as the second
second arg to WRITE-FASD.   As a lisp object it is actually a vector,
whose body coincides with:

struct fasd {
  object stream;   /* lisp object of type stream */
  object table;  /* hash table used in dumping or vector on input*/
  object eof;      /* lisp object to be returned on coming to eof mark */
  object direction;    /* holds Cnil or Kinput or Koutput */
  object package;  /* the package symbols are in by default */
  object index;     /* integer.  The current_dump index on write  */
  object filepos;   /* nil or the position of the start */ 
  object table_length; /*    On read it is set to the size dump array needed
		     or 0
		     */
  object macro ; }

We did not use a defstruct for this, because we want the compiler to use this
and it makes bootstrapping more difficult.   It is in "cmpnew/fasdmacros.lsp"


FWRITE-FASD-TOP
Function in the SI package:
Args: (X FASD-STREAM)
Write X to FASD-STREAM.

FREAD-FASD-TOP
Function in the SI package:
Args: (FASD-STREAM)
Read the next object from FASD-STREAM.   Return the eof-value of FASD-STREAM if we
encounter an eof marker put out by CLOSE-FASD.   Encountering end of actual file
stream causes an error.

FCLOSE-FASD
Function in the SI package:
Args: (FASD-STREAM)
On output write an eof marker to the associated file stream, and then
make FASD-STREAM invalid for further output.   It also attempts to write
information to the stream on the size of the index table needed to read from the
stream from the last open.    This is useful in growing the array.
It does not alter the file stream, other than for writing this information to it.
The file stream may be reopened for further use.   It is an error
to OPEN-FASD the same file or file stream again with out first calling CLOSE-FASD.




FFIND-SHARING-TOP
Function in the SI package:
Args: (x table)
X is any lisp object and TABLE is an eq hash table.  This walks through X
making entries to indicate the frequency of symbols,lists, and arrays.
Initially items get -1 when they are first met, and this is decremented by 1
each time the object occurs.  Call this function on all the objects in a fasd
file, which you wish to share structure.

V*CC*
Variable in the COMPILER package:
Has value a string which controls which C compiler is used by GCL.
Usually this string is obtained from the machine.defs file, but
may be reset by the user, to change compilers or add an include path.

V*SPLIT-FILES*
Variable in the COMPILER package:
This affects the behaviour of compile-file, and is useful for cases where
the C compiler cannot handle large C files resulting from lisp compilation.
This scheme should allow arbitrarily long lisp files to be compiled.

If the  value [default NIL] is a positive integer, then the source file will
be compiled into several object files whose names have 0,1,2,.. prepended,
and which will be loaded by the main object file.     File 0 will
contain compilation of top level forms thru position *split-files* in the
lisp source file, and file 1 the next forms, etc.   Thus a 180k file
would probably result in three object files (plus the master object file
of the same name) if *split-files* was set to 60000.
The package information will be inserted in each file.

V*LOAD-PATHNAME*
Variable in the SI package:
Load binds this to the pathname of the file being loaded.

V*COMPILE-ORDINARIES*
Variable in the COMPILER package:
If this has a non nil value [default = nil], then all top level
forms will be compiled into machine instructions.    Otherwise
only defun's, defmacro's, and top level forms beginning
with (progn 'compile ...) will do so.

FDEFINE-INLINE-FUNCTION
Macro in the SI package:
Args: (fname vars &body body)
This is equivalent to defun except that VARS may not contain
&optional, &rest, &key or &aux.   Also a compiler property is
added, which essentially saves the body and turns this into
a let of the VARS and then execution of the body.   This
last is done using si::DEFINE-COMPILER-MACRO
Example:
(si::define-inline-function myplus (a b c) (+ a b c))

FDEFINE-COMPILER-MACRO
Macro in the SI package:
Args:(fname vars &body body)
FNAME may be the name of a function, but at compile time the macro
expansion given by this is used.

(si::define-compiler-macro mycar (a) `(car ,a))

TDBL
Function in the SI package:
Args:()
Invoke a top level loop, in which debug commands may be entered.
These commands may also be entered at breaks, or in the error
handler.
See SOURCE-LEVEL-DEBUG

TNLOAD
Function in the SI package:
Args:(file)
Load a file with the readtable bound to a special readtable, which
permits tracking of source line information as the file is loaded.
see SOURCE-LEVEL-DEBUG

TSOURCE-LEVEL-DEBUG

PRELIMINARY:

In emacs load (load "dbl.el") from the gcl/doc directory.
[ It also requires gcl.el from that directory.    Your system
administrator should do make in the doc directory, so that
these files are copied to the standard location.]

OVERVIEW:

   Lisp files loaded with si::nload will have source line information about
them recorded.  Break points may be set, and functions stepped.  Source code
will be automatically displayed in the other window, with a little arrow beside
the current line.  The backtrace (command :bt) will show line information and
you will get automatic display of the source as you move up and down the stack.

FUNCTIONS:
break points which have been set.
   si::nload (file)
      load a lisp file collecting source line information.
    
   si::break-function (function &optional line absolute)
     set up a breakpoint for FUNCTION at LINE relative to start or ABSOLUTE

EMACS COMMANDS:
M-x dbl makes a dbl buffer, suitable for running an inferior gcl.
It has special keybindings for stepping and viewing sources.

Inferior Dbl Mode:
Major mode for interacting with an inferior Dbl process.
The following commands are available:

C-c l           dbl-find-line

ESC d           dbl-:down
ESC u           dbl-:up
ESC c           dbl-:r
ESC n           dbl-:next
ESC i           dbl-:step
ESC s           dbl-:step


M-x dbl-display-frame displays in the other window
the last line referred to in the dbl buffer.

ESC i and ESC n in the dbl window,
call dbl to step and next and then update the other window
with the current file and position.

If you are in a source file, you may select a point to break
at, by doing C-x SPC.

Commands:
Many commands are inherited from shell mode. 
Additionally we have:

M-x dbl-display-frame display frames file in other window
ESC i advance one line in program
ESC n advance one line in program (skip over calls).
M-x send-dbl-command used for special printing of an arg at the current point.
C-x SPACE sets break point at current line.

----------------------------

   When visiting a lisp buffer (if gcl.el is loaded in your emacs) the command
c-m-x evaluates the current defun into the process running in the other window.
Line information will be kept.  This line information allows you to set break
points at a given line (by typing C-x \space on the line in the source file
where you want the break to occur.  Once stopped within a function you may
single step with M-s.  This moves one line at a time in the source code,
displaying a little arrow beside your current position.  M-c is like M-s,
except that function invocations are skipped over, rather than entered into.
M-c continues execution.

   Keywords typed at top level, in the debug loop have
a special meaning:

  :delete  [n1] [n2] .. -- delete all break points or just n1,n2
  :disable [n1] [n2] .. -- disable all break points or just n1,n2
  :enable  [n1] [n2] .. -- enable all break points or just n1,n2
  :info  [:bkpt]      --print information about 
  :break [fun] [line] -- break at the current location, or if
     fun is supplied in fun.   Break  at the beginning unless a
     line offset from the beginning of fun is supplied.
  :fr [n] go to frame n   When in frame n, if the frame is interpreted,
    typing the name of locals, will print their values.   If it is compiled
    you must use (si::loc j) to print `locj'.   Autodisplay of the source
    will take place if it is interpreted and the line can be determined.
  :up [n] go up n frames from the current frame.
  :down [n] go down n frames
  :bt [n] back trace starting at the current frame and going to top level
     If n is specified show only n frames.
  :r  If stopped in a function resume.   If at top level in the dbl
   loop, exit and resume an outer loop.
  :q  quit the computation back to top level dbl loop.
  :step step to the next line with line information
  :next  step to the next line with line information skipping over function
    invocations.

TLOW-LEVEL-DEBUG

Use the following functions to directly access KCL stacks.

(SI:VS i)	Returns the i-th entity in VS.
(SI:IHS-VS i)	Returns the VS index of the i-th entity in IHS.
(SI:IHS-FUN i)	Returns the function of the i-th entity in IHS.
(SI:FRS-VS i)	Returns the VS index of the i-th entity in FRS.
(SI:FRS-BDS i)	Returns the BDS index of the i-th entity in FRS.
(SI:FRS-IHS i)	Returns the IHS index of the i-th entity in FRS.
(SI:BDS-VAR i)	Returns the symbol of the i-th entity in BDS.
(SI:BDS-VAL i)	Returns the value of the i-th entity in BDS.

(SI:SUPER-GO i tag)
	Jumps to the specified tag established by the TAGBODY frame at
	FRS[i].  Both arguments are evaluated.  If FRS[i] happens to be
	a non-TAGBODY frame, then (THROW (SI:IHS-TAG i) (VALUES)) is
	performed.

For the KCL stacks, refer to Appendix B of the KCL Report.

TENVIRONMENT
The environment in GCL which is passed to macroexpand and
other functions requesting an environment, should be a
list of 3 lists.    The first list looks like ((v1 val1) (v2 val2) ..)
where vi are variables and vali are their values.    
The second is a list of ((fname1 . fbody1) (fname2 . fbody2) ...)
where fbody1 is either (macro lambda-list lambda-body) or
(lambda-list lambda-body) depending on whether this is a macro
or a function.   The third list contains tags and blocks.


FBREAK-FUNCTION
Function in the SI package:
Args: (function &optional line absolute)
Set a breakpoint for a FUNCTION at LINE if the function has source
information loaded.  If ABSOLUTE is not nil, then the line is understood to be
relative to the beginning of the buffer.  See also dbl-break-function, the
emacs command.

FXDR-OPEN
Function in the SI package:
Args: (stream)
Returns an object suitable for passing to XDR-READ if the stream
is an input stream, and XDR-WRITE if it was an output stream.
Note the stream must be a unix stream, on which  si::fp-input-stream
or si::fp-output-stream would act as the identity.


FFP-INPUT-STREAM
Function in the SI package:
Args: (stream)
Return a unix stream for input associated to STREAM if possible,
otherwise return nil.

FFP-OUTPUT-STREAM
Function in the SI package:
Args: (stream)
Return a unix stream for output associated to STREAM if possible,
otherwise return nil.


FXDR-READ
Function in the SI package:
Args: (stream element)
Read one item from STREAM of type the type of ELEMENT.    The representation
of the elements is machine independent.    The xdr routines are what is
used by the basic unix rpc calls.    

FXDR-WRITE
Function in the SI package:
Args: (stream element)
Write to STREAM the given ELEMENT.



FCOND-ERROR
Macro in the SERROR package: Args: (variables body-form &body clauses) If a
condition is signalled during evaluation of body-form, The first of VARIABLES
is bound to the condition, and the clauses are evaluated like cond clauses, If
the cond falls off the end, then the error is signaled at this point in the
stack.  For the moment the rest of the VARIABLES are ignored.  This form is in
the lsp/serror.lsp file, which is not automatically loaded.

>(import 'serror::cond-error)
>(defun joe(x) (+ 1 x))
JOE
>(defun te (n)
  (cond-error (er) (progn (1+ n))
     ((null n) (print n) (print er) n)
     ((symbolp n) (print n))))
TE
>(te 2)
3
>(te 'a)
A 
>(te "a")

Error: "a" is not of type NUMBER.
Error signalled by +.
Broken at APPLY.  Type :H for Help.
>>:bt
#0   APPLY {loc0=#<compiled-function system:universal-error-handler>} [ihs=19]
#1   + {loc0=1,loc1="a",loc2=:wrong-type-argument,loc3=nil,loc4=+,loc5="",loc6="~S is n...} [ihs=15]
#2   JOE {} [ihs=14]
#3   TE {} [ihs=6]
#4   EVAL {loc0=nil,loc1=nil,loc2=nil,loc3=(lambda-block te (n) ...),loc4="a"} [ihs=5]


FCOND-ANY-ERROR
Macro in the SERROR package: Args: (variables body-form &body clauses) If a
This is similar to COND-ERROR but is faster.  It uses catch and throw rather
than closures.  The main difference is where the error handler (if the error
is not handled automatically)

V*TOP-LEVEL-HOOK*
Variable in the SI package:
If this variable is has a function as its value at start up time, then
it is run immediately after the init.lsp file is loaded.    This is useful
for starting up an alternate top level loop.

TINIT
If the file init.lsp exists in the current directory, it is
loaded at startup.  The first argument passed to the executable image
should be the system directory.  Normally this would be gcl/unixport.
This directory is stored in the si::*system-directory* variable.  If
the file sys-init.lsp exists in the system directory, it is loaded
before init.lsp.  See also si::*TOP-LEVEL-HOOK*.

FMULTIPLY-BIGNUM-STACK
Function in the SI package:
Args: (n)
Increase the internal bignum stack by a factor of N.  Normally space on this
stack is recovered after each complete lisp expression is evaluated.  However
if you are dealing with large integers, you may need to use this function 
to increase the stack.


TWINDOW
A sample program for drawing things on X windows from lisp
is included in the file gcl/lsp/littleXlsp.lsp

That routine invokes the corresponding C routines in XLIB.
So in order to use it you must `faslink' in the X routines.
Directions are given at the beginning of the lisp file,
for either building them into the image or using faslink.

This program is also a good tutorial on invoking C from lisp.

FRUN-PROCESS
Function in the SI package:
Args: (string arglist)

Execute the command STRING in a subshell passing the strings in the
list ARGLIST as arguments to the command.  Return a two way stream
associated to this.  Use si::fp-output-stream to get an associated
output stream or si::fp-input-stream.

Bugs: It does not properly deallocate everything, so that it will fail
if you call it too many times.

TFOREIGN-FUNCTIONS

See documentation on defentry and faslink.
The documentWindow discusses some examples.
The file lsp/littleXlsp.lsp provides a good example.
