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()Sandal Joie Slide Jacory Women's Coal 4BPBw0Zqx.

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

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).

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.

Indigo Sandal Black Rd Women's Show Slide q1rBY61v 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;
}
