TCC : Tiny C Compiler

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.

Compilation Speed

Compilation speed for the Links
Browser project. There are 76936 lines (including
headers). 1950947 lines (67.2 MBytes) are compiled because the same headers are
included in many files. TinyCC is about 9 times faster than
GCC.

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