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. + |
