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 machine code for i386, x86_64, arm, aarch64 or
 riscv64. Compiles and links about 10 times faster than 'gcc -O0'.
- UNLIMITED! Any C dynamic library can be used directly. TCC is
 heading toward 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 Linux, BSD variants or macOS hosts:
 ./configure
 make
 make test
 make install
 Notes: On BSD hosts, gmake should be used instead of make.
 For Windows read tcc-win32.txt.
makeinfo must be installed to compile the doc. 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 <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.
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'.

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