NAME
cc - C compiler (2BSD)
SYNOPSIS
cc [ option ] ... file ...
DESCRIPTION
Cc is the UNIX C compiler. Cc accepts several types of arguments: Arguments whose names end with `.c' are taken to be C source programs; they are compiled, and each object pro- gram 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 programs and are assem- bled, 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 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 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). -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 programs, 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 programs, and send the result to the standard output. -C prevent the macro preprocessor from eliding comments. -o output Name the final output file output. If this option is used the file `a.out' will be left undisturbed. -Dname=def -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. -Ldir Library archives are sought first in directories named in -L options, then in directories on a stan- dard list. -Bstring 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. -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 string is taken to be `/usr/c/'. 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.

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 regis- ters. 3rd Berkeley Distribution June 7, 1985 CC(1)
