[1] 使用 LLVM 实现一门简单的语言 本文跟着LLVM Tutorial教程完成,加上了一些注释。本文中的代码并非工程最佳实践。 1 目标 用LLVM 实现一门简单的语言 Kaleidoscope,实现对如下代码的编译运行: 代码语言:txt 复制 # 斐波那契数列函数定义 def fib(x) if x < 3 then 1 else fib(x - 1) + fib(x - 2...

Then you will find an executable namediron-kaleidoscopein thetargetdirectory. Basic variant of the Kaleidoscope language In this tutorial we will use a simple functional language named Kaleidoscope. In this chapter its basic variant will be presented. New features will be added in the next chapters...
I'm interested in LLVM and want to try simple things with it. That's why I've started official LLVM tutorial -Kaleidoscope. What's it all about? This tutorial runs through the implementation of a simple language, showing how fun and easy it can be. This tutorial will get you up and ...
本节我们将让 Kaleidoscope 支持可变变量,首先我们看如下 C 代码: 由于变量 X 的值依赖于程序的执行路径,会加入一个 phi node 来选取分支结果。上面代码的 LLVM IR 如下: 上面的 X 是符合 SSA 格式的,但是这里真正的难题是给可变变量赋值时怎么自动添加 phi node。我们先了解一些信息,LLVM 要求寄存器变量是 SSA...
In this series I walkthrough the LLVM "Kaleidoscope" Tutorial, where you follow step by step to create your first programming language frontend using LLVM as the backend. Last time we updated the parser for binary operators to support custom operators. This time we'll work on the code generat...
这是默认的硬编码值,因为我们使用shell重定向将源代码放入Kaleidoscope编译器。在通常的前端,您会有一个输入文件名,它会放在那里。 通过DIBuilder发出调试信息的最后一件事是,我们需要“确定”调试信息。原因是DIBuilder的底层API的一部分,但请确保在Main的末尾,导出模块之前执行此操作: 代码语言:javascript 复制 D...
In this series I walkthrough the LLVM "Kaleidoscope" Tutorial, where you follow step by step to create your first programming language frontend using LLVM as the backend. Last time we updated the code for the custom binary operators, this time we'll try to finish up the custom unary operato...
Here you can see the big picture with all the functions referencing each other. This wraps up the third chapter of the Kaleidoscope tutorial. Up next, we’ll describe how to add JIT codegen and optimizer support to this so we can actually start running code!3.6. Full Code Listing Here is...
