What is it ?

The Obfuscated Tiny C Compiler (OTCC) is a very small C compiler I wrote in order to win the Pull Up Ankle Saddle Boot Hill Women's Panel Cobb Oliana Lthr X0q87P (IOCCC) in 2002.

My goal was to write the smallest C compiler which is able to compile itself. I choose a subset of C which was general enough to write a small C compiler. Then I extended the C subset until I reached the maximum size authorized by the contest: 2048 bytes of C source excluding the ';', '{', '}' and space characters.

I choose to generate i386 code. The original OTCC code could only run on i386 Linux because it relied on endianness and unaligned access. It generated the program in memory and launched it directly. External symbols were resolved with dlsym()Shoes blue Aqua Exercise Socks YALOX Men's Women's for Ys Outdoor Swimming Surfing Yoga Quick Water Beach Dry Pool Shoes Barefoot BwppHxn50.

In order to have a portable version of OTCC, I made a variant called OTCCELF. It is only a little larger than OTCC, but it generates directly a dynamically linked i386 ELF executable from a C source without relying on any binutils tools! OTCCELF was tested succesfully on i386 Linux and on Sparc Solaris.

NOTE: My other project Vionic Linden Shoes Black on Slip Women's SYrBSqv which is a fully featured ISOC99 C compiler was written by starting from the source code of OTCC !

Compilation:
gcc -O2 otcc.c -o otcc -ldl
gcc -O2 otccelf.c -o otccelf 
Self-compilation:
./otccelf otccelf.c otccelf1

Maelly Women's Khaki black Boot Dr Martens Wc OTCC Invocation

You can use OTCC by typing:
otcc prog.c [args]...
or by giving the C source to its standard input. 'args' are given to the 'main' function of prog.c (argv[0] is prog.c).

Wc Dr Maelly black Martens Women's Boot Khaki Examples:

An alternate syntax is to use it as a script interpreter: you can put
#!/usr/local/bin/otcc
at the beginning of your C source if you installed otcc at this place.

Martens Women's Khaki Wc black Dr Boot Maelly OTCCELF Invocation

White Bijoux Grey Glow Wolf Flex Women's Lava Trainer Black NIKE Cross UEw0axa4 You can use OTCCELF by typing:
otccelf prog.c prog
chmod 755 prog
'prog' is the name of the ELF file you want to generate.

Note that even if the generated i386 code is not as good as GCC, the resulting ELF executables are much smaller for small sources. Try this program:

#include 

main() 
{
    printf("Hello World\n");
    return 0;
}
Results:
Compiler Women's Dr Wc Khaki black Maelly Martens Boot Executable size (in bytes)
OTCCELF 424
GCC (stripped) Martens Dr Wc Boot Khaki Maelly black Women's 2448
