Tiny C Compiler - Make the best x86 Linux C compiler in less than 8192 bytes.
|
|
-----------------------------------------------------------------------------
|
|
|
|
Differences with ANSI C:
|
|
-----------------------
|
|
|
|
- Preprocessor: only '#define xx yy' is supported. Recursive defined
|
|
supported. All other directives are not supported.
|
|
|
|
- Types: int, char, void, pointers and functions are
|
|
supported. Function pointers are also supported. struct, union and
|
|
typedef not supported.
|
|
|
|
- Operations: 'x=' not supported.
|
|
|
|
- Keywords: the following keywords are supported: int void char if
|
|
else while break return for.
|
|
|
|
- Symbol scope: local variables supported, but they cannot have the
|
|
same name as global variables.
|
|
|
|
Features:
|
|
--------
|
|
|
|
- SMALL! You can compile and execute C code everywhere, for example on
|
|
rescue disks.
|
|
|
|
- FAST! tcc generate x86 code. No byte code overhead.
|
|
|
|
- Compile and execute C source directly. No linking necessary.
|
|
|
|
- C script supported : just add '#!/usr/bin/tcc' at the first line of
|
|
your C source, and execute it directly from the command line !
|
|
|
|
- All C library functions can be used via dynamic linking.
|
|
|
|
-------------------------------------------------------------------------
|
|
An even smaller compiler can be build from tcc by activating the
|
|
define 'TINY'. The following changes from tcc:
|
|
|
|
- Comments are not supported.
|
|
|
|
- Parsing: No char constants. No '\r' and '\t' in strings. Only base
|
|
10 numbers are supported.
|
|
|
|
- no 'for' loops.
|
|
|
|
- Operations: '?:', ',', 'x=', shifts, '&&', '||', '!', '~' not supported.
