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.

Compiler Time(s) lines/second MBytes/second

TinyCC 0.9.22 2.27 859000 29.6

GCC 3.2 -O0 20.0 98000 3.4
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.
