cc - C compiler
cc [ option ] ... file ...
_C_c 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' 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.
-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.
-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.
-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.

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