       cc, pcc - C compiler

       cc [ option ] ... file ...

       pcc [ option ] ... file ...

       Cc is the UNIX C compiler.  It accepts several types of arguments:

       Arguments  whose names end with `.c' are taken to be C source programs; they are compiled,
       and each object program is left on the file whose name is that of  the  source  with  `.o'
       substituted  for  `.c'.	The `.o' file is normally deleted, however, if a single C program
       is compiled and loaded all at one go.

       In the same way, arguments whose names end with `.s' are taken to be assembly source  pro-
       grams and are assembled, producing a `.o' file.

       The following options are interpreted by cc.  See ld(1) for load-time options.

       -c      Suppress the loading phase of the compilation, and force an object file to be pro-
	       duced even if only one program is compiled.

       -p      Arrange for the compiler to produce code which counts the  number  of  times  each
	       routine is called; also, if loading takes place, replace the standard startup rou-
	       tine by one which automatically calls monitor(3) at  the  start	and  arranges  to
	       write out a mon.out file at normal termination of execution of the object program.
	       An execution profile can then be generated by use of prof(1).

       -f      In systems without hardware floating-point, use a version of the C compiler  which
	       handles	floating-point	constants and loads the object program with the floating-
	       point interpreter.  Do not use if the hardware is present.

       -O      Invoke an object-code optimizer.

       -S      Compile the named C programs, and leave the assembler-language  output  on  corre-
	       sponding files suffixed `.s'.

       -P      Run  only the macro preprocessor and place the result for each `.c' file in a cor-
	       responding `.i' file and has no `#' lines in it.

       -E      Run only the macro preprocessor and send the result to the standard  output.   The
	       output is intended for compiler debugging; it is unacceptable as input to cc.

       -o output
	       Name  the  final output file output.  If this option is used the file `a.out' will
	       be left undisturbed.

       -Dname  Define the name to the preprocessor, as if by  `#define'.   If  no  definition  is
	       given, the name is defined as 1.

       -Uname  Remove any initial definition of name.

       -Idir   `#include'  files whose names do not begin with `/' are always sought first in the
	       directory of the file argument, then in directories named in -I options,  then  in
	       directories on a standard list.

	       Find  substitute  compiler passes in the files named string with the suffixes cpp,
	       c0, c1 and c2.  If string is empty, use a standard backup version.

	       Find only the designated compiler passes in the files whose names are  constructed
	       by  a  -B  option.   In	the  absence  of  a  -B option, the string is taken to be

       Other arguments are taken to be either loader option  arguments,  or  C-compatible  object
       programs,  typically  produced  by an earlier cc run, or perhaps libraries of C-compatible
       routines.  These programs, together with the results of any  compilations  specified,  are
       loaded (in the order given) to produce an executable program with name a.out.

       The  major  purpose  of the `portable C compiler', pcc, is to serve as a model on which to
       base other compilers.  Pcc does not support options -f, -E, -B, and -t.	It  provides,  in
       addition to the language of cc, unsigned char type data and initialized bit fields.

       The diagnostics produced by C itself are intended to be self-explanatory.  Occasional mes-
       sages may be produced by the assembler or loader.  Of these, the most mystifying are  from
       the  assembler,	as(1),	in particular `m', which means a multiply-defined external symbol
       (function or data).

       Pcc is little tried on the PDP11; specialized code generated for that machine has not been
       well shaken down.  The -O optimizer was designed to work with cc; its use with pcc is sus-
