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.
