Tiny C Compiler

News

[Note: I am no longer working on TCC. Check the mailing list to get
up to date information.]

Features

  * SMALL! You can compile and execute C code everywhere, for example
    on rescue disks (about 100KB for x86 TCC executable, including C
    preprocessor, C compiler, assembler and linker).
  * FAST! tcc generates x86 code. No byte code overhead. Compile,
    assemble and link several times faster than GCC.
  * 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 and GNU-like assembler 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.
  * With libtcc, you can use TCC as a backend for dynamic code
    generation.

Measures were done on a 2.4 GHz Pentium 4. Real time is measured.
Compilation time includes compilation, assembly and linking.

More up to date tests are available: 1, 2, 3, 4.
