This is a simple C compiler that created with lex and yacc and it is my compiler design course project :)
In archlinux simply install byacc and use it for creating y.tab.c and lex for creating y.lex.c.
I think that fairly simple packages are needed for this porject. It would be just byacc and bison and lex.
sudo pacman -S byacc
sudo apt-get install byacc lex
yacc is the fundamental parts of a compiler. Parsers are integrated in .yacc file and there is no optimization for it. However, we have a simple semantic analyzer available to be used here. I try to generate llvm assembly in order to use llvm's code optimizer and other benefits of it.
you can do it by using assembler.py. You need to just give three address code which is generated by compiler to python the script as first argument python2 assmebler.py threeaddresscode.txt.
Follow the mybash.sh script so that you can figure out how this project is working.
