NAME
pcc - APE C compiler driver
SYNOPSIS
pcc [ option ... ] [ name ... ]
DESCRIPTION
Pcc compiles and loads C programs, using APE (ANSI C/POSIX)
include files and libraries. Named files ending with .c are
preprocessed with cpp(1), then compiled with one of the com-
pilers described in 8c(1), as specified by the environment
variable $objtype. The object files are then loaded using
one of the loaders described in 8l(1). The options are:
-+ Accept C++ // comments.
-o out Place loader output in file out instead of the
default 8.out, v.out, etc.
-P Omit the compilation and loading phases; leave the
result of preprocessing name.c in name.i.
-E Like -P, but send the result to standard output.
-c Omit the loading phase.
-p Insert profiling code into the executable output.
-w Print compiler warning messages.
-W Print all the messages that -w would print as warn-
ings, but make them errors.
-llib Include /$objtype/lib/ape/liblib.a as a library dur-
ing the linking phase.
-B Don't complain about functions used without ANSI
function prototypes.
-V Enable void* conversion warnings, as in 8c(1).
-v Echo the preprocessing, compiling, and loading com-
mands before they are executed.
-x file Produce an export file in the executable, as
described in 8l(1).
-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 Undefine the name to the preprocessor, as if by
`#undef'.
-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 /$objtype/include/ape.
-N Don't optimize compiled code.
-S Print an assembly language version of the object
code on standard output.
-T Pass type signatures on all external and global
entities. The signature is based on the C signof
operator. See dynld(2).
-a Instead of compiling, print on standard output acid
functions (see acid(1)) for examining structures
declared in the source files.
-aa Like -a except that functions for structures
declared in included header files are omitted.
-F Enable vararg type checking as described in 8c(1).
This is of limited use without the appropriate
#pragma definitions.
-f (ARM only) Generate VFP hardware floating point
instructions.
The APE environment contains all of the include files and
library routines specified in the ANSI C standard (X3.159-
1989), as well as those specified in the IEEE Portable Oper-
ating System Interface standard (POSIX, 1003.1-1990, ISO
9945-1). In order to access the POSIX routines, source pro-
grams should define the preprocessor constant _POSIX_SOURCE.
FILES
/sys/include/ape directory for machine-independent
#include files.
/$objtype/include/ape directory for machine-dependent
#include files.
/$objtype/lib/ape/libap.a ANSI C/POSIX library.

BUGS
The locale manipulation functions are minimal. Signal func-
tions and terminal characteristic handlers are only mini-
mally implemented. Link always fails, because Plan 9
doesn't support multiple links to a file. The functions
related to setting effective user and group ids cannot be
implemented because the concept doesn't exist in Plan 9.
