本次实验参照助教在文档中的提示，对符号表做了如下设计。注意本次实验中符号表不再依赖 `Symbol` 和 `Type` 包，而是直接存储 `String` 对 `LLVMValueRef` 的映射。 13 | 14 | ![](lab5/Lab5-Scope-1672913283336-4.png) 15 | 16 | 本次实验重新设计了 `LLVMVisitor` 类。 17 | 18 | ## 实验困难 19 | 20 | 试验过程中笔者通过和王星云同学交流掌握了部分 API 的使用方法。笔者向助教求助解决了 `expected instruction opcode` 的测试用例报错问题。 21 | --------------------------------------------------------------------------------

| 3 | ## 实现功能 4 | 5 | 本次实验完成了以下功能： 6 | 7 | 1. 全局变量声明和使用 8 | 1. 条件语句 9 | 10 | ## 实验设计 11 | 12 | 本次实验重新设计了 `LLVMVisitor` 类，其中全局变量相关内容主要是对 `visitVarDecl` 方法的修改。 13 | 14 | ## 实验困难 15 | 16 | 笔者实验过程中被三个困难的测试用例，报错信息如下： 17 | 18 | ``` 19 | hardtest1.sy：0（Aborted (core dumped) ） 20 | hardtest2.sy：0（Aborted (core dumped) ） 21 | hardtest3.sy：0（Aborted (core dumped) ） 22 | ``` 23 | 24 | 和顾龙助教沟通后，构建了引发错误的测试用例： 25 | 26 | ``` 27 | int a[10] = {}; 28 | 29 | int f(int a) { 30 | return 0; 31 | } 32 | 33 | int main() { 34 | a[1] = 1; 35 | return 0; 36 | } 37 | ``` 38 | 39 | 通过输出日志发现，函数参数 `a` 被定义在了全局作用域内，这是 `visitFuncDef` 方法当中的疏忽所致，修复了该 bug 后完成了本次实验。 40 | --------------------------------------------------------------------------------

/docus/lab1.md: -------------------------------------------------------------------------------- 1 | # 编译原理 Lab1 实验报告 2 | 3 | ## 实现功能 4 | 5 | 本次实验完成了以下功能： 6 | 7 | 1. 对 SysY 语言进行词法分析并报告错误的词法单元位置 8 | 2. 对不同进制的字面整型值进行转换 9 | 10 | ## 实验困难 11 | 12 | 实验所遇到的最大困难是使用 `make antlr` 时报错： 13 | 14 | ```bash 15 | eaglebear2002@EagleBear2002-HP:/mnt/c/Users/37756/Documents/NJU/2022Fall/Compilers/Lab$ make antlr 16 | java -jar /usr/local/lib/antlr-*-complete.jar -listener -visitor -long-messages ./src/SysYLexer.g4 17 | error(99): ./src/SysYLexer.g4::: grammar SysYLexer has no non-fragment rules 18 | make: *** [Makefile:32: antlr] Error 1 19 | ``` 20 | 21 | 笔者不理解该报错信息，反复检查词法规约，确认无误后在 Google 等搜索引擎需求帮助，未果。 22 | 23 | 笔者在检查项目目录时发现了问题所在： 24 | 25 | 笔者使用命令行编译项目在 `out` 目录中得到了 `SysYLexer.g4` 文件，并无意中注释掉该文件中所有词法规约内容。笔者之后未更改 `out/SysYLexer.g4` 内容，而是在修改 `src/SysYLexer.g4`。后面使用命令行编译时，系统总是默认先对 `out/SysYLexer.g4` 进行编译。 26 | 27 | 笔者删掉 `./out` 目录后解决了这一困难。

《编译原理》课程实验 2 | 3 | ## 项目功能 4 | 5 | 该项目完成了从 SysY 语言的子集到 LLVMIR 的编译过程。 6 | 7 | SysY 语言的介绍参考 [SysY语言定义](docus/SysY语言定义.pdf)。 8 | 9 | ## 实验报告 10 | 11 | 8 个实验的实验报告在 `/docus` 目录中，包含每个实验的功能、设计和问题解决。 12 | 13 | ## 运行说明 14 | 15 | ### 操作系统 16 | 17 | 使用 Windows + WSL2（Ubuntu 20.04）完成项目开发。 18 | 19 | 在 Windows 系统中，使用 IDEA 也可运行。 20 | 21 | 使用 JDK 11 完成实验。 22 | 23 | ### 配置 Antlr4 24 | 25 | 若使用 IDE，仅需安装 Antlr 的插件即可，以 IDEA 为例，在左上角，文件->设置->插件，搜索 ANTLR4 即可找到插件，下载后重启即可，之后可通过该插件处理 `.g4` 文件。 26 | 27 | 若文本编辑器则需自行安装 Antlr 28 | 29 | 前往 [Antlr 官网](https://www.antlr.org/download.html)，下载 Complete ANTLR 4.9.X.jar，对于 Linux 也可以选择从命令行，使用： 30 | 31 | ```shell 32 | curl -O https://www.antlr.org/download/antlr-4.9.1-complete.jar 33 | ``` 34 | 35 | ### 配置 LLVM 36 | 37 | Linux 下安装： 38 | 39 | ```bash 40 | sudo apt-get install llvm 41 | sudo apt-get install clang 42 | ``` 43 | 44 | 安装后可通过如下命令测试，出现版本信息即为安装成功： 45 | 46 | ```bash 47 | clang -v 48 | lli --version 49 | ``` 50 | 51 | ### 问题解决 52 | 53 | 配置过程中遇到的问题解决方案参见： 54
