Re: [Tinycc-devel] Can a biggener (and idiot) like me read and understand TCC's backend so I can create my own frontend with it?

Thanks! However, I don't understand how this will help me. I mean, I don't even 
want to create an intepreter to begin with. So this has nothing to do with what 
I want to make. Unless you are referring to the frontend so in this case, It 
will probably be a good idea to read this book. Or maybe I should make an 
intepreter in the end? Hmmmmm....
