Chapter 1

Acorn C/C++

Acorn C/C++ is a set of C/C++ programming tools for
use under the RISC OS operating system. The tools use
the Norcroft compiler suite and were authored by Codemist
and Acorn Computers.[2] The tools provide some facilities
offered by a fully integrated development environment.
Acorn included a copy of the Norcroft compiler targeted at
the ARM architecture for RISC OS in the following devel-
opment software.

• Acornsoft ANSI C

• Acornsoft ANSI C (Release 2)

• Acorn ANSI C (Release 3) – 1989[3]

• Acorn Desktop C (Release 4)

• Acorn C/C++ (Release 5) – 1995[4]

1.1 History

Acorn’s work on ANSI C compilers was begun around
1987,[2] with a commercial release in 1988 for its
Archimedes computer.[5] Desktop C and Desktop Assem-
bler were released in 1991.[2] Codemist worked primarily
on the ANSI C standard, while Acorn concentrated on the
RISC OS specifics and optimisation for the ARM. Both par-
ties exchanged sources regularly.[2][6]

The tools were originally developed by university academics
Alan Mycroft and Arthur C Norman of Codemist.[7] Their
development was taken up by Acorn and subsequently taken
over by Castle Technology, who later added the lacking
C99[8] support. Castle funded further development by
means of a subscription scheme.[9] In early 2009, develop-
ment and sales of the tools were transferred to RISC OS
Open.[10]

1.2 Uses

The Norcroft compiler can be used to produce RISC OS
modules, as well as compiling parts of the operating system
itself. Before beginning development of the Inform pro-
gramming language, Graham Nelson originally used Nor-
croft C to develop his text adventure Curses.[11][12]

The suite of tools is currently the only means of building a
working copy of RISC OS, although it is ultimately intended
that this will also be possible using a cross compiler, e.g.
using the free software GCC system.[13]

development of the compiler was a joint venture between
Norcroft (at the time Arthur Norman and Alan Mycroft–two
academics from Cambridge University Computing Labs)
and the PLG at Acorn. Sources were regularly exchanged
between both parties but, generally, Norcroft were respon-
sible for adherence to the emerging ANSI standard, whilst
Acorn concentrated on the RISC OS specifics of the C li-
brary and on common subexpression elimination, register al-
location and peephole optimisation for the ARM.

Chapter 2

Amsterdam Compiler Kit

The Amsterdam Compiler Kit (ACK) is a retargetable
compiler suite and toolchain written by Andrew Tanenbaum
and Ceriel Jacobs, and is MINIX’s native toolchain. The
ACK was originally closed-source software (that allowed
binaries to be distributed for MINIX as a special case), but
in April 2003 it was released under an open source BSD
license. It has frontends for programming languages C,
Pascal, Modula-2, Occam, and BASIC.
The ACK’s notability stems from the fact that in the early
1980s it was one of the first portable compilation systems
designed to support multiple source languages and target
platforms.[1][2]

The ACK achieves maximum portability by using an
intermediate language using bytecode, called EM. Each lan-
guage front-end produces EM object files, which are then
processed through several generic optimisers before being
translated by a back-end into native machine code.
ACK comes with a generic linker and librarian capable of
manipulating files in the ACK’s own a.out-based format; it
will work on files containing EM code as well as native ma-
chine code. However, EM code cannot be linked to native
machine code without translating the EM binary first.

Aztec C

Aztec C is a C compiler for MS-DOS, Apple II DOS 3.3
and ProDOS, Commodore 64, early Macintosh, CP/M-80,
Amiga, and Atari ST.

3.1 History

Manx Software Systems of Shrewsbury, New Jersey, pro-
duced C compilers beginning in the 1980s targeted at pro-
fessional developers for a variety of platforms up to and in-
cluding PCs and Macs.
Manx Software Systems was started by Harry Suckow, with
partners Thomas Fenwick, and James Goodnow II, the two
principal developers. They were all working together at
another company at the time. Suckow had started several
companies of his own anticipating the impending growth of
the PC market, with each company specializing in different
kinds of software. A demand came for compilers first and
he disengaged himself from the other companies to pursue
Manx and Aztec C.
Suckow took care of the business side, Fenwick specialized
in front-end compiler development, and Goodnow special-
ized in back-end compiler development. Another devel-
oper, Chris Macey, worked with them for a while on 80XX
development and in other areas.
The name “Manx” was selected from a list of cats for no
particular reason except that the name Suckow wanted to
use was taken.
One of the main reasons for Aztec C’s early success was
the floating point support for the Z80 compiler which was
extended to the Apple II shortly after. Suckow insisted on
adding floating point.
During the move to ANSI C in 1989, Robert Sherry who
was with Manx at the time and interested in the minutiae of
standards represented them on the ANSI committee but left
shortly after. He also fixed numerous bugs in the Aztec C
after Chris Macey and Thomas Fenwick left the company.
By this time Microsoft had targeted competitors for their C

compiler and Aztec C was being pushed-out of the general
IBM-PC compiler market, followed by competition with
Apple’s MPW C on the Macintosh side and Lattice C on
the Amiga after SAS bought them.
In 1989 Thomas Fenwick left to work for Microsoft, and
James Goodnow worked on Aztec C occasionally but was
pursuing other projects outside the company and eventu-
ally left the company altogether. Suckow employed about
20 people at that time. Chris Macey returned as a consul-
tant but eventually left to become chief scientist for another
company. Mike Spille joined Manx as a developer along
with the late Jeff Davis (embedded systems).
Throughout the 1990s they continued to make their Aztec
C. As their market share dropped, they tried to make the
move to specializing in embedded systems development,[1]
but it was too late. They disappeared a few years back fol-
lowing the loss of market presence of some of their target
platforms (various 6502 machines, Atari and Amiga 68xxx,
etc.).[2]

In the end, Jeff Davis and Mike Spille helped Harry Suckow
keep the company going before Suckow finally closed it.
Suckow is still the Copyright holder for Aztec C.
Many professional developers used the Manx Software
Systems’ Aztec C compiler until it became operationally
extinct.[3][4]

3.2 Current status

Aztec C remains copyrighted and has not been placed into
the public domain. Harry Suckow, who started Manx Soft-
ware Systems with partners Thomas Fenwick and James
Goodnow II, is the copyright holder.
Manx Software Systems native Aztec C compilers for Ap-
ple II development have been available for free download
from the Internet for a number of years as disk images for
Apple II emulators without copyright infringement action
being sought by Manx Software Systems.

tribution exists for Aztec C for the Commodore Amiga.[5]
A fourth free Internet distribution exists for their MS-DOS
8086 native compiler,[5] and a fifth exists for a limited ver-
sion of their MS-DOS cross-compiler for Apple II ProDOS
8.

3.3 Current use

Emulators for these older now-obsolete platforms have be-
come popular with enthusiasts and hobbyists, and most em-
ulators are free or almost free. No commercial market ex-
ists for programs or development environments that run on
these older now-obsolete platforms.
Despite the fact that these compilers are no longer of any
commercial value, the native Aztec C Compilers for these
platforms are still as usable as they ever were on their re-
spective native platforms, and the MS-DOS Aztec C cross-
development compilers for these platforms work under
Windows XP. This means that a C programmer-enthusiast
can create programs in an emulator or in the Windows en-
vironment then run them on an emulator or transfer them
to a real (but obsolete) target computer using a serial cable
or some other means.

Chapter 4

BDS C

BDS C (or the BD Software C Compiler) is a compiler for a
sizeable subset of the C programming language, that ran on
and generated code for the Intel 8080 and Zilog Z80 proces-
sors. It was the first C compiler for CP/M.[1] It was written
by Leor Zolman[2] and first released in 1979 when he was
20 years old. “BDS” stood for “Brain Damage Software”.
BDS C was very popular and influential among CP/M users
and developers in the 8-bit microcomputer era. It ran much
faster and was more convenient to use than other Z80-
hosted compilers of the time. It was possible to run BDS C
on single-floppy machines with as little as 30K of RAM –
something of a minor miracle by comparison to most other
commercial compilers which required many passes and the
writing of intermediate files to disk. Around 75,000 copies
were sold, including a stripped down Japanese incarnation.
A number of important commercial CP/M products were
written in the BDS C subset of the C language, including
PeachText from PeachTree Software, MINCE and Scrib-
ble from Mark of the Unicorn, and most of the soft-
ware in the Perfect Software suite including Perfect Writer,
PerfectCalc, PerfectSpeller and PerfectFiler (which suite
was bundled with the Kaypro).
BDS C supported pointers and was very memory efficient,
with fast compilation speeds. Weak points were that the
floating point math routines were incompatible with the
Unix C compiler’s, and its relocatable object files were not
compatible with the Microsoft assembler, making it more
difficult to integrate C code with assembly language.[3]

BDS C was bundled with a significant subset of the Unix
system written in about 1980, called MARC (Machine As-
sisted Resource Coordinator). This effort in some ways re-
sembled GNU, though MARC was to be able to run CP/M
software through emulation. Unfortunately MARC’s au-
thor, Ed Ziemba, perished in a snorkeling accident before
he could complete the project.[4]

In 2002, with its commercial viability long past, Leor Zol-
man released BDS C’s source code into the public domain,
thus making it free and open-source software. Written in
8080 assembly language, the code is now mostly of histor-

ical rather than practical interest, but it is interesting to pe-
ruse for anyone wishing to see how sizeable programs for
small computers were written in those days.

(Prentice-Hall, 1978), but it does contain a large subset of
the important features.

Borland Turbo C

For technical reasons, “Turbo C#” redirects here. For the
article on the Turbo C# IDE, see Turbo C Sharp.

Turbo C is a discontinued Integrated Development En-
vironment and compiler for the C programming language
from Borland. First introduced in 1987, it was noted for its
integrated development environment, small size, fast com-
pile speed, comprehensive manuals and low price.
In May 1990, Borland replaced Turbo C with Turbo C++.
In 2006, Borland reintroduced the Turbo moniker.

5.1 Early history

In the early 1980s, Borland enjoyed considerable success
with their Turbo Pascal product and it became a popular
choice when developing applications for the PC. Borland
followed up that success by releasing Turbo Basic, Turbo
Prolog and Turbo C. Turbo C had the same properties as
Turbo Pascal: an integrated development environment, a
fast compiler (though not near the speed of Turbo Pascal[1]),
a good editor, and a competitive price.
Turbo C was not as successful as the Pascal-sister prod-
uct. First, C was a language for professional programming
and systems development rather than a school language.
Turbo C competed with other professional programming
tools (Microsoft C, Lattice C, Watcom C, etc.). Turbo C
did, however, have advantages in speed of compiled code,
large project support and price. It is developed in C.

5.2 Version history

Version 1.0 (May 13, 1987) offered the first integrated de-
velopment environment for C on IBM PCs. Like many Bor-
land products of the time, the software was bought from
another company (in this case Wizard C by Bob Jervis[2]),
and branded with the “Turbo” name. It ran in 384 kB of
memory. It allowed inline assembly with full access to C

symbolic names and structures, supported all memory mod-
els, and offered optimizations for speed, size, constant fold-
ing, and jump elimination.[3]

Version 1.5 (January 1988) was an incremental improve-
ment over version 1.0. It included more sample programs,
improved manuals and bug fixes. It was shipped on five 360
KB diskettes of uncompressed files, and came with sample
C programs, including a stripped down spreadsheet called
mcalc. This version introduced the header file
(which provided fast, PC-specific console I/O routines).
Version 2.0 (late 1988) featured the first “blue screen” ver-
sion, which would be typical of all future Borland releases
for MS-DOS. The American release did not have Turbo As-
sembler or a separate debugger. (These were sold separately
as Turbo Assembler.) Turbo C, Asm, and Debugger were
sold together as a suite. This seems to describe another re-
lease: Featured Turbo Debugger, Turbo Assembler, and an
extensive graphics library. This version of Turbo C was
also released (in Germany only) for the Atari ST; the pro-
gram was not maintained by Borland, but sold and renamed
PureC.
With the release of Turbo C++ 1.0 (in 1990), the two prod-
ucts were folded into one and the name “Turbo C” was dis-
continued. The C++ compiler was developed under con-
tract by a company in San Diego, and was one of the first
“true” compilers for C++ (until then, it was common to use
pre-compilers that generated C code, ref. Cfront).

5.3 Freeware release

In 2006, Borland’s successor, Embarcadero Technologies,
re-released Turbo C and the MS-DOS versions of the Turbo
C++ compilers as freeware.[4][5][6]

cc65

cc65 is a complete cross development package for 65(C)02
systems, including a powerful macro assembler, a C
compiler, linker, librarian and several other tools.
It is based on a C compiler that was originally adapted for
the Atari 8-bit computers by John R. Dunning. The original
C compiler is a Small C descendant but has several exten-
sions, and some of the limits of the original Small C com-
piler are gone.
The toolkit has largely been expanded by Ullrich von Basse-
witz and other contributors. The actual cc65 compiler, a
complete set of binary tools (assembler, linker, etc.) and
runtime library are under a license identical to zlib’s.[1] The
ca65 cross-assembler is one of the most powerful 6502
cross-assemblers available under an open-source license.
The compiler itself is almost completely ANSI C compati-
ble, though not completely. The C library is quite extensive,
and allows extensive usage of the target platform’s hard-
ware. stdio is supported on many platforms, as is Borland-
style conio.h screen handling. GEOS is also supported
on the Commodore 64 and even the Apple II. The library
supports many of the Commodore platforms (C64, C128,
C16/116/Plus/4, P500 and 600/700 family), Apple II fam-
ily, Atari 8-bit family, Oric Atmos, Nintendo Entertainment
System, Watara Supervision game console and Ohio Scien-
tific Challenger 1P.[2]

The officially supported host systems include Linux,
Microsoft Windows, DOS and OS/2, but the source code
itself is quite portable and has been reported to work almost
unmodified on many platforms beside these.

6.1 Supported API

6.1.1 static

• conio (text-based console I/O non-scrolling)

• dio (block-oriented disk I/O bypassing the file system)

6.1.2 dynamic

• em (expanded memory, used for all kinds of memory
beyond the 6502’s 64K barrier, similar EMS)

• joystick (relative input devices)

• mouse (absolute input devices)

• serial (communication)

• tgi (2D graphics primitives inspired by BGI)

Note: For static libraries, “Yes” means the feature is avail-
able. For dynamic libraries, the columns list the number of
available drivers.

ccache

ccache is a software development tool that caches the output
of C/C++ compilation so that the next time, the same com-
pilation can be avoided and the results can be taken from
the cache. This can greatly speed up recompiling time. The
detection is done by hashing different kinds of information
that should be unique for the compilation and then using the
hash sum to identify the cached output. Ccache is licensed
under the GNU General Public License.

Chapter 8

CFLAGS

CFLAGS and CXXFLAGS are either the name of
environment variables or of Makefile variables that can be
set to specify additional switches to be passed to a compiler
in the process of building computer software.
These variables are usually set inside a Makefile and are
then appended to the command line when the compiler is
invoked. If they are not specified in the Makefile, then
they will be read from the environment, if present. Tools
like autoconf’s ./configure script will usually pick them up
from the environment and write them into the generated
Makefiles. Some package install scripts, like SDL, allow
CFLAGS settings to override their normal settings (instead
of append to them), so setting CFLAGS can cause harm in
this case.
CFLAGS enables the addition of switches for the C com-
piler, while CXXFLAGS is meant to be used when invok-
ing a C++ compiler. Similarly, a variable CPPFLAGS ex-
ists with switches to be passed to the C or C++ preproces-
sor.
These variables are most commonly used to specify
optimization or debugging switches to a compiler, as for ex-
ample -g, -O2 or (GCC-specific) -march=athlon.

Clang

This article is about the Clang compiler. For the phe-
nomenon of rhyming word association, see Clanging.

Clang /ˈklæŋ/[4] is a compiler front end for the pro-
gramming languages C, C++, Objective-C, Objective-C++,
OpenMP,[5] OpenCL, and CUDA. It uses LLVM as its
back end and has been part of the LLVM release cycle since
LLVM 2.6.
It is designed to be able to replace the full GNU Com-
piler Collection (GCC). Its contributors include Apple,
Microsoft, Google, ARM, Sony, Intel and Advanced Micro
Devices (AMD). It is open-source software,[6] with source
code released under the University of Illinois/NCSA Li-
cense, a permissive free software licence.
The Clang project includes the Clang front end and the
Clang static analyzer and several code analysis tools.[7]

9.1 Background

Starting in 2005, Apple made extensive use of LLVM in
a number of commercial systems,[8] including the iPhone
software development kit (SDK) and integrated develop-
ment environment (IDE) Xcode 3.1.
One of the first uses of LLVM was an OpenGL code com-
piler for OS X that converts OpenGL calls into more fun-
damental calls for graphics processing units (GPU) that do
not support certain features. This allowed Apple to sup-
port the entire OpenGL application programming inter-
face (API) on computers using Intel Graphics Media Ac-
celerator (GMA) chipsets, increasing performance on those
machines.[9] For GPUs that support it, the code is compiled
to exploit fully the underlying hardware, but on GMA ma-
chines, LLVM compiles the same OpenGL code into sub-
routines to ensure continued proper function.
LLVM was intended originally to use GCC’s front end, but
GCC turned out to cause some problems for developers of
LLVM and at Apple. The GCC source code is a large and

somewhat cumbersome system for developers to work with;
as one long-time GCC developer put it, “Trying to make the
hippo dance is not really a lot of fun”.[10]

Apple software makes heavy use of Objective-C, but the
Objective-C front-end in GCC is a low priority for GCC
developers. Also, GCC does not fit smoothly into Apple’s
IDE.[11] Finally, GCC is licensed under GNU General Pub-
lic License (GPL) version 3, which requires developers who
distribute extensions for, or modified versions of, GCC to
make their source code available, whereas LLVM has a
BSD-like license[12] which does not force users to release
their source code changes when publishing compiled bina-
ries of those changes.
Apple chose to develop a new compiler front end from
scratch, supporting C, Objective-C and C++.[11] This
“clang” project was open-sourced in July 2007.[13]

9.2 Design

Clang is intended to work atop LLVM.[12] The combina-
tion of Clang and LLVM provides most of the toolchain,
to allow replacing the full GCC stack. Because it is built
with a library-based design, like the rest of LLVM, Clang
is easy to embed into other applications. This is one reason
why most OpenCL implementations are built with Clang
and LLVM.
One of Clang’s main goals is to provide a library-based ar-
chitecture,[14] to allow the compiler to be more tightly tied
to tools that interact with source code, such as an integrated
development environment (IDE) graphical user interface
(GUI). In contrast, GCC is designed to work in a classic
compile-link-debug cycle, and integrating it with other tools
is not always easy. For instance, GCC uses a step called fold
that is key to the overall compile process, which has the side
effect of translating the code tree into a form that looks un-
like the original source code. If an error is found during or
after the fold step, it can be difficult to translate that back
into one location in the original source. Also, vendors us-

14 CHAPTER 9. CLANG

ing the GCC stack within IDEs use separate tools to index
the code, to provide features like syntax highlighting and
autocomplete.
Clang is designed to retain more information during the
compiling process than GCC, and to preserve the overall
form of the original code. The goal of this is to make it eas-
ier to map errors back into the original source. The error
reports offered by Clang are also aimed to be more detailed
and specific, as well as machine-readable, so IDEs can in-
dex the output of the compiler during compiling. Modular
design of the compiler can offer source code indexing, syn-
tax checking, and other features normally associated with
rapid application development systems. The parse tree is
also more suitable for supporting automated code refactor-
ing, as it directly represents the original source code.
Clang is a compiler for only C-like languages, including C,
C++, Objective-C, Objective-C++, OpenCL, and CUDA.
For other languages, including Java, Fortran, and Ada,
LLVM remains dependent on GCC or another compiler
frontend. In many cases, Clang can be used or swapped out
for GCC as needed, with no other effects on the toolchain
as a whole. It supports most of the commonly used GCC
options.

9.3 Performance and GCC compati-
bility

Clang is designed to be highly compatible with GCC.[15]
Clang’s command-line interface is similar to and shares
many flags and options with GCC. Clang implements many
GNU language extensions and enables them by default.
Clang implements many GCC compiler intrinsics purely
for compatibility. For example, even though Clang imple-
ments atomic intrinsics which correspond exactly with C11
atomics, it also implements GCC’s __sync_* intrinsics for
compatibility with GCC and libstdc++. Clang also main-
tains ABI compatibility with GCC-generated object code.
In practice Clang can often be used as a drop-in replace-
ment for GCC.
Clang’s developers aim to reduce memory footprint and
increase compilation speed compared to competing com-
pilers, such as GCC. In October 2007, they report that
Clang compiled the Carbon libraries well over twice as fast
as GCC, while using about one-sixth GCC’s memory and
disk space.[16] However, as of 2011 this was not a typical
result.[17][18] As of mid-2014, Clang won more than a third
of the benchmarks, with GCC winning most.[19]

While there are still a few tests where performance of a
Clang-compiled program lags behind performance of the
GCC-compiled program, by large factors (up to 5.5x),[19]

it has been reported that Clang “continues to be under very
active development,” and a hope was expressed for further
improvement.[17]
