A Naive Decaf Compiler

ACM1501 U201514613 苟桂霖

introduction

This project implements a Java-like language called decaf, which compiles .decaf code into LLVM middle code(.ll).
It features:

  1. use Flex as tokenizier;
  2. use Bison as Praser;
  3. support limited static analysis;
  4. use LLVM Builder to generate final middle code.

requirement

This project requires 0. Linux distribution

  1. GCC and Clang supporting C++17.
  2. latest bison and flex
  3. LLVM
  4. zlib1g-dev (to solve "-lz not found")
  5. /usr/bin/python3

usage

To run it, first run ./init.sh to generate necessary directory structure, and fix any error infomation if exists

After installing the tools above, run ./init.sh to generate necessary directory structure.

Then, run ./checker.sh to compile and link programs. You can modify ./checker.sh to test other program, or manually do it at your wish.
