Micro-cc

A toy compiler made for compiler principle course's lab, using flex/bison/LLVM.

How to compile micro-cc

My development environment:

macOS Catalina 10.15.7

Apple clang version 12.0.0 (clang-1200.0.32.2)
Target: x86_64-apple-darwin19.6.0

flex 2.5.35 Apple(flex-32)

bison (GNU Bison) 3.7

LLVM 11.0.0 (prebuilt binarys)

Only macOS is tested, but it should run on Linux.

Set LLVM_DIR in CMakeList.txtbefore compiling.
