Tiny C Compiler

C Scripting Everywhere - The Smallest ANSI C compiler

这是一个 翻译提示文本的补丁 . 可能也会在未来Merge其它patch.

对于TCC来说, 加入太多语言支持会增加它的体积, 这是不明智的. 这个分支只会包含中文的提示本地化.

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:

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

   ./configure
   make
   make test
   make install

By default, tcc is installed in /usr/local/bin. ./configure --help shows configuration options.

Introduction

We assume here that you know ANSI C. Look at the example hello_world.c to know what the programs look like.

The include file <tcclib.h> 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.

Examples

hello_world.c: simplest example (hello world). Can also be launched directly as a script: './hello_world.c'.

find_num.c: more complicated example: find a number with the four operations given a list of numbers (benchmark).

fib.c: compute fibonacci numbers (benchmark).

gui.c: more complicated: X11 program. Very complicated test in fact because standard headers are being used !

glic_hello.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'.
