NAME
cc - C compiler
SYNOPSIS
cc [ option ] ... file ...
DESCRIPTION
_C_c is the UNIX C compiler. N.B.: _c_c has been recently modi-
fied to accept arbitrary length identifiers and to produce a
new object file format; see _o_l_d(8) for information on deal-
ing with old format programs.
_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.
-g Have the compiler produce additional symbol table
information for _s_d_b(1). Also pass the -lg flag to
_l_d(1).
-w Suppress warning diagnostics.
-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 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.
-R Passed on to _a_s, making initialized variables shared
and read-only.

-S Compile the named C programs, and leave the
assembler-language output on corresponding files
suffixed `.s'.
-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.
-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, ccom 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, short or unsigned short variables in registers. It
previously produced poor, and in some cases incorrect, code
for such declarations.
