They aren't necessarily enough (they won't be for me, at least with the way that I'm currently writing the parser), but they do provide a good starting point, since you don't have to put as much time into the lexer & first-stage parser. > Actually i want to do something at low level , like some micro controller > and linux device drivers project by which i can explore my C at lower > level. but as i don't know much about those thing, i thought that i have to > start from this. > Have you considered a virtual machine & assembly language? There's all sorts of interesting low-level stuff you can do in that field (for example, why have I been using more C than C++ recently? So I can work on a virtual machine that uses a file as it's memory! C++ gives you enough tools that you can't safely use in that context that it slows you down). If the virtual machine was small enough, then you could even run it ON microcontrollers. Also, an assembler wouldn't necessarily be AS complex to write, as long as you restricted it to 1 operation per line, with a fixed format for the operations: thus, it could be a good introduction to Bison & Flex. If you decide afterwards that you wanted to run C on the virtual machine, then you would be in a better position to write your own compiler, or you could modify TCC to compile for it. _______________________________________________ Tinycc-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/tinycc-devel
