创作一个简单的编程语言3 加上VLLM后端
让AI帮助完成加上VLLM后端
我看到您想要为八皇后问题解决方案添加LLVM后端。让我先检查一下当前的工作环境,看看是否已经有LLVM相关的文件或配置:
Search codebase for 'llvm|LLVM'
让我查看一下Arc编译器的源代码结构,了解如何添加LLVM后端:
ArcCompiler_UTF8.java1-50
让我继续查看编译器的更多结构,特别是关于代码生成的部分:
Search codebase for 'visitChildren|apply|eval'
现在让我查看Arc编译器的完整结构,特别是关于代码生成和输出的部分:
ArcCompiler_UTF8.java800-843
现在让我查看ANTLR语法文件,了解语言结构:
arc
现在让我查看ANTLR语法文件,了解Arc语言的结构:
custom_arc_parser.g41-100
现在让我查看词法文件,了解所有支持的token:
custom_arc_lexer.g41-100
现在让我查看Arc编译器的main方法,了解当前的执行流程:
ArcCompiler_UTF8.java1-50
现在让我查看Arc编译器的完整结构,特别是关于函数调用和代码生成的部分:
Search codebase for 'visitFunction_call|visitChildren|apply'
现在让我查看Arc编译器的visitFunction_call方法,了解当前的函数调用机制:
ArcCompiler_UTF8.java547-650
现在我了解了Arc编译器的结构。当前的实现是一个解释器,它直接执行AST节点,而不是生成代码。要添加LLVM后端,我需要:
- 1.
创建一个新的LLVM代码生成器
- 2.
修改编译器以支持代码生成模式
- 3.
添加LLVM依赖
让我先创建一个新的LLVM编译器版本:

提示:
=== LLVM编译信息 ===
如需完整LLVM编译,请安装LLVM工具链:
1. 下载LLVM: https://github.com/llvm/llvm-project/releases
2. 安装后添加llc和clang到PATH环境变量
3. 运行 compile_llvm.bat 脚本
但是有时候github下载特别慢....
官网在这:The LLVM Compiler Infrastructure Project
但是也需要到github下载....
