参考My First Language Frontend with LLVM Tutorial的C++代码实现的swift版Kaleidoscope。
Kaleidoscope是LLVM教程中实现的demo语言，以下是它的介绍:
This tutorial introduces the simple “Kaleidoscope” language, building it iteratively over the course of several chapters, showing how it is built over time. This lets us cover a range of language design and LLVM-specific ideas, showing and explaining the code for it all along the way, and reduces the overwhelming amount of details up front. We strongly encourage that you work with this code - make a copy and hack it up and experiment.
brew install llvm
brew install pkg-config
# 在.bash_profile下配置llvm命令行，具体情况根据你所安装的llvm版本不同
export PATH=/usr/local/Cellar/llvm/8.0.0_1/bin:$PATH;
# 来自LLVMSwift的脚本
swift utils/make-pkgconfig.swift
# 编译工程
