NAME
cc, CC - C compilers
SYNOPSIS
cc [ option ] ... file ...
CC [ option ] ... file ...
DESCRIPTION
Cc compiles the language C; and CC compiles C++. File arguments ending
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 nor‐
mally deleted, however, if a single C program is compiled and
loaded all at one go.
.s are taken to be assembly source programs and are assembled, pro‐
ducing a `.o' file.
The following options are interpreted by cc and CC. See ld(1) for
load-time options.
-c Suppress the loading phase of the compilation, and force an ob‐
ject file to be produced even if only one program is compiled.
-g Have the compiler produce additional symbol table information
for sdb(1) or pi(9.1). Also pass the -lg flag to ld(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 arranges to
gather profiling data for later examination by prof(1).
-O Invoke an object-code improver.
-R Passed on to as, 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 programs, and
send the result to the standard output.
-F[c] Run only the macro preprocessor and the C++ front end cfront on
the named C programs, and send the result to the standard ouput.
If c is present, produce output suitable for input to cc.
-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 di‐
rectories named in -I options, then in directories on a standard
list.
These options are peculiar to cc:
-Bstring
Find substitute compiler passes in the files named string with
the suffixes cpp, ccom and c2. If string is empty, use a stan‐
dard 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/'.
These options are peculiar to CC:
-.suffix
Instead of the standard output, place -E and -F output in files
whose name is that of the source with .suffix substituted for
`.c'.
+E Use C rules for scope of non-local names.
+S Print debugging information from cfront on the standard error
file.
+d Don't expand inline functions.
+xname Take size and alignment information from file name for cross
compiling.

ccC=/bin/cc
environment parameters and their defaults; see FILES below
Other arguments are taken to be either loader options 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 the compilers are intended to be self-ex‐
planatory. Occasional messages may be produced by the assembler as(1)
or loader ld(1).
BUGS
CC can not yet handle certain constructs, for which it reports, "sorry,
not implemented."
To permit the use of standard, untyped C libraries, CC makes the loader
name of the first function having a given name agree with the loader
name from cc. Thus
overload read(int,char*,int), read(vector*);
arranges for read(2) to be called, as well as another `read' for a
newly defined type. Reversing the declarations would cause chaos, even
in programs that do not directly call read(2), but do use stdio(3) in‐
put.
