But then, you need a C compiler to compile your C compiler! Of course, -the very first C compiler was not written in C (because how would it be -compiled?). Instead, it was slowly built up, starting from a very basic -assembler, eventually reacing a full-scale compiler. This process is known as -bootstrapping. In this repository, we'll explore how that's done. Each directory -represents a new "stage" in the process. The first one, "00", is a hand-written -executable, and the last one will be a C compiler. Each directory has its own -README.txt explaining in full what's going on. - --- instruction set -- -x86-64 has a *gigantic* instruction set. The manual for it is over 2,000 pages -long! So, it makes sense to select only a small subset of it to use for all the -stages of our compiler. The set I've chosen can be found in instructions.txt (a -work in progress). I think it achieves a pretty good balance between -having few enough instructions to be manageable and having enough -instructions to be useable. - --- license -- - -This software is in the public domain.
