NAME
     cc - C compiler (2BSD)

SYNOPSIS
     cc [ option ] ... file ...

DESCRIPTION
     _C_c is the UNIX C compiler.  _C_c 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' sub-
     stituted for `.c'.  The `.o' file is normally deleted, how-
     ever, 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 programs and are assembled, pro-
     ducing a `.o' file.

     The following options are interpreted by _c_c.  See _l_d(1) for
     load-time options.

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

     -w      Suppress warning diagnostics.

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

     -O      Invoke an object-code improver.

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

     -M      Run only the macro preprocessor on the named C pro-
	     grams, requesting it to generate Makefile dependen-
	     cies and send the result to the standard output.

     -E      Run only the macro preprocessor on the named C pro-
	     grams, and send the result to the standard output.

     -C      prevent the macro preprocessor from eliding com-
	     ments.

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

     -D_n_a_m_e=_d_e_f
     -D_n_a_m_e  Define the _n_a_m_e to the preprocessor, as if by
	     `#define'.  If no definition is given, the name is
	     defined as "1".

     -U_n_a_m_e  Remove any initial definition of _n_a_m_e.

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

     -L_d_i_r   Library archives are sought first in directories
	     named in -L options, then in directories on a stan-
	     dard list.

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

     -t[p012]
	     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 _s_t_r_i_n_g is taken
	     to be `/usr/c/'.

     Other arguments are taken to be either loader option argu-
     ments, or C-compatible object programs, typically produced
     by an earlier _c_c 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.

DIAGNOSTICS
     The diagnostics produced by C itself are intended to be
     self-explanatory.	Occasional messages may be produced by
     the assembler or loader.

BUGS
     The compiler currently ignores advice to put char, unsigned
     char, long, float, or double variables in registers.
