Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler

-----------------------------------------------------------------------

Features:

--------

- SMALL! You can compile and execute C code everywhere, for example on

  rescue disks.

- FAST! tcc generates optimized x86 code. No byte code

  overhead. Compile, assemble and link about 7 times faster than 'gcc

  -O0'.

- UNLIMITED! Any C dynamic library can be used directly. TCC is

  heading torward full ISOC99 compliance. TCC can of course compile

  itself.

- SAFE! tcc includes an optional memory and bound checker. Bound

  checked code can be mixed freely with standard code.

- Compile and execute C source directly. No linking or assembly

  necessary. Full C preprocessor included. 

- C script supported : just add '#!/usr/local/bin/tcc -run' at the first

  line of your C source, and execute it directly from the command

  line.

Documentation:

-------------

1) Installation on a i386 Linux host (for Windows read tcc-win32.txt)

   ./configure

   make

   make test

   make install

Alternatively, out-of-tree builds are supported: you may use different

directories to hold build objects, kept separate from your source tree:

   mkdir _build

   cd _build

   ../configure

   make

   make test

   make install

By default, tcc is installed in /usr/local/bin.

./configure --help  shows configuration options.

2) Introduction

We assume here that you know ANSI C. Look at the example ex1.c to know

what the programs look like.

The include file  can be used if you want a small basic libc

include support (especially useful for floppy disks). Of course, you

can also use standard headers, although they are slower to compile.

You can begin your C script with '#!/usr/local/bin/tcc -run' on the first

line and set its execute bits (chmod a+x your_script). Then, you can

launch the C code as a shell or perl script :-) The command line

arguments are put in 'argc' and 'argv' of the main functions, as in

ANSI C.

3) Examples

ex1.c: simplest example (hello world). Can also be launched directly

as a script: './ex1.c'.

ex2.c: more complicated example: find a number with the four

operations given a list of numbers (benchmark).

ex3.c: compute fibonacci numbers (benchmark).

ex4.c: more complicated: X11 program. Very complicated test in fact

because standard headers are being used ! As for ex1.c, can also be launched

directly as a script: './ex4.c'.

ex5.c: 'hello world' with standard glibc headers.

tcc.c: TCC can of course compile itself. Used to check the code

generator.

tcctest.c: auto test for TCC which tests many subtle possible bugs. Used

when doing 'make test'.

4) Full Documentation

Please read tcc-doc.html to have all the features of TCC.

Additional information is available for the Windows port in tcc-win32.txt.
