Just a toy compiler for me to avoid the regret of never implemented any compiler from scratch in the future.
Currently my intention is to implement a simple jit compiler (of course this interpreter which is actually a semantic analyzer may be deprecated in the future), using llvm to generate machine code. The completely handwritten part is actually just an llvm front end. I plan to write some llvm optimize pass in the future just for fun
- lexer
- parser
- interpreter
- jit compiler
- opt passes
使用访问者模式重构代码生成部分。同时抛弃解释器，实现一个独立的语法分析器。
clang-12+llvm is needed as the jit compiler will use llvm ir. In ubuntu20.04, just use apt to install them.
sudo apt install clang
sudo apt install llvm
this project use CMake for building
use following command to build
mkdir build && cd ./build
cmake .. -DLLVM_DIR=$(llvm-config --cmakedir) -DCMAKE_CXX_COMPILER="clang++"
make all -j$(nproc) # this will make all the tests
both the output of lexer and parser used the "unix-liked terminal color setting", so it may not output nicely in windows (windows terminal can display the color correctly)
