NAME
cc - C compiler
SYNOPSIS
cc [ -c ] [ -p ] [ -f ] [ -O ] [ -S ] [ -P ] file ...
DESCRIPTION
Cc is the UNIX C compiler. It accepts three types of argu-
ments:
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.
The following flags are interpreted by cc. See ld (I) for
load-time flags.
-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 rou-
tine by one which automatically calls the monitor sub-
routine (III) 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 gen-
erated by use of prof (I).
-f In systems without hardware floating-point, use a ver-
sion of the C compiler which handles floating-point
constants and loads the object program with the
floating-point interpreter. Do not use if the hard-
ware is present.
-O Invoke an object-code optimizer.
-S Compile the named C programs, and leave the
assembler-language output on corresponding files suf-
fixed `.s'.
-P Run only the macro preprocessor on the named C pro-
grams, and leave the output on corresponding files
suffixed `.i'.
Other arguments are taken to be either loader flag argu-
ments, 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
1
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. Of these, the most mystifying are
from the assembler, in particular ``m,'' which means a
multiply-defined external symbol (function or data).
