toy compiler for a pascal-like language (in bison + flex)
just make it. You'll need flex, bison, and a C compiler.
Ah, and ruby, because I haven't written a C interpreter (yet?)
make test. If git diff is clean you didn't break anything.
You can add new .pas files to the tests/ folder and make test will
generate the .asm and .txt files for you. Don't forget to add
all the test files to git.
