+date: 2025-03-19T20:57:31.1928528+08:00
+tags:
+- 技术笔记
+- LLVM
+---
+
+MLIR是多层次中间表示形式（Multi-Level Intermediate Representation），是LLVM项目中提供的一项新编译器开发基础设施，使得编译器开发者能够在源代码和可执行代码之间定义多层IR来保留程序信息指导编译优化。本博客指导如何创建一个独立（out-of-tree）的MLIR项目。
+
+<!--more-->
+
+## 编译LLVM和MLIR
+
+考虑到大多数的Linux发行版在打包LLVM时不会编译MLIR，因此自行编译安装包括MLIR项目的LLVM就成为开发独立MLIR项目的前置条件。
+
+首先在GitHub上下载LLVM的源代码包，我这里选择最新的稳定版本`20.1.0`。
+
+```shell
+wget https://github.com/llvm/llvm-project/releases/download/llvmorg-20.1.0/llvm-project-20.1.0.src.tar.xz
+```
+
+下载之后解压进入，准备进行构建。
+
+```shell
+tar xvf llvm-project-20.1.0.src.tar.xz
+cd llvm-project-20.1.0.src
+```
+
+创建`build`文件夹，使用下面的命令进行生成构建文件。在这里选择使用`Release`构建类型，安装的位置是`~/.local/share/llvm`文件夹，构建的项目包括`llvm`、`clang`和`mlir`三个项目，并指定使用系统上的`clang`和`clang++`编译器作为编译过程中使用的编译器。
+
+```shell
+mkdir build
+cd build
+cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="/home/ricardo/.local/share/llvm-20.1.0" -DLLVM_ENABLE_PROJECTS="llvm;clang;mlir" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_INSTALL_UTILS=true ../llvm
+```
+
+![image-20250319192618697](./mlir-standalone/image-20250319192618697.png)
+
+生成构建文件之后使用`ninja`进行构建。
+
+```shell
+ninja
+```
+
+![image-20250319194742171](./mlir-standalone/image-20250319194742171.png)
+
+构建在我的i5-13600K上大约需要20分钟。
+
+构建完成之后进行安装。
+
+```shell
+ninja install
+```
+
+## 编译MLIR官方的独立项目
+
+MLIR的官方提供了一个独立项目，项目文件夹在`mlir/examples/standalone`中，将这个文件夹中的内容复制到我们需要的地方，尝试使用上面构建的`mlir`进行构建。
+
+```shell
+cp -r ~/Downloads/llvm-project-20.1.0.src/mlir/examples/standalone mlir-standalone 
+cd mlir-standalone
+```
+
+### 不启用测试
+
+编译过程中可能遇到的最大问题是`llvm-lit`，这个使用`python`编写的LLVM集成测试工具，在`standalone`的`README.md`中要求编译过程中使用`LLVM_EXTERNAL_LIT`变量指定到LLVM编译过程中生成的`llvm-lit`可执行文件。
+
+> 也许就是因为`llvm-lit`是用Python撰写的，所以`llvm-lit`不会安装到`PREFIX`指定的位置。
+
+不过我们可以禁用测试（笑）。在`CMakeLists.txt`文件中注释对于测试文件夹的添加：
+
+```cmake
+add_subdirectory(include)
+add_subdirectory(lib)
+if(MLIR_ENABLE_BINDINGS_PYTHON)
+  message(STATUS "Enabling Python API")
+  add_subdirectory(python)
+endif()
+#add_subdirectory(test)
+add_subdirectory(standalone-opt)
+add_subdirectory(standalone-plugin)
+add_subdirectory(standalone-translate)
+
+```
+
+回到构建文件夹，使用如下的`cmake`指令生成构建文件。
+
+```shell
+export LLVM_DIR=/home/ricardo/.local/share/llvm-20.1.0
+cmake -G Ninja -DMLIR_DIR=$LLVM_DIR/lib/cmake/mlir  ..
+```
+
+可以顺利通过编译。
+
+![image-20250319202218503](./mlir-standalone/image-20250319202218503.png)
+
+### 启用测试
+
+但是测试还是非常重要的。我们尝试启动测试看看，取消对于测试文件夹的注释：
+
+```shell
+rm -rf build && mkdir build && cd build
+cmake -G Ninja -DMLIR_DIR=$LLVM_DIR/lib/cmake/mlir  ..
+```
+
+很好顺利报错，报错的提示是缺失`FileCheck`、`count`和`not`。
+
+![image-20250319202553644](./mlir-standalone/image-20250319202553644.png)
+
+那么按照`README.md`中的提示添加上来自构建目录的`llvm-lit`会怎么样呢？
+
+```shell
+rm -rf build && mkdir build && cd build
+export LLVM_BUILD_DIR=/home/ricardo/Downloads/llvm-project-20.1.0.src/build
+cmake -G Ninja -DMLIR_DIR=$LLVM_DIR/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$LLVM_BUILD_DIR/bin/llvm-lit ..
+```
+
+同样的报错，看来问题不是出在这里。
+
+经过对于LLVM文档的仔细研究，发现原来是没有启动这个变量：
+
+![image-20250319204057832](./mlir-standalone/image-20250319204057832.png)
+
+遂修改最初的LLVM编译指令。
+
+重新运行来自`README.md`的构建文件生成指令之后，测试也完美运行通过：
+
+```shell
+ninja test-standalone
+```
+
+![image-20250319204522857](./mlir-standalone/image-20250319204522857.png)
+
+不过这个还是有一点令我不是特别满意，这依赖了一个来自于构建目录的工具`llvm-lit`，如果我编译安装的时候眼疾手快的删除了编译目录不就完蛋了。而且我都**standalone**了还依赖似乎有点说不过去？
+
+于是发现了一篇从`pip`上下载使用`llvm-lit`的[博客](https://medium.com/@mshockwave/using-llvm-lit-out-of-tree-5cddada85a78)和一个LLVM Discourse上面的[帖子](https://discourse.llvm.org/t/running-llvm-lit-on-external-project-test-file-derived-from-standalone-fails/67787)，遂进行尝试。
+
+首先在当前目录下创建一个虚拟环境，并下载安装`llvm-lit`。
+
+```shell
+python -m venv .llvm-lit
+source .llvm-lit/bin/activate
+pip install lit
+```
+
+~~不过这个库似乎没有提供运行入口点，需要我们手动创建一个可执行的`python`文件：~~
+
+```python
+#!/usr/bin/env python
+from lit.main import main
+if __name__ == '__main__':
+    main()
+```
+
+经哥们纠正说`lit`包在某个版本之后会安装`lit`的可执行文件，在安装之后可以直接在命令行调用`lit`。因此在激活虚拟环境之后，`cmake`中直接在`LLVM_EXTERNAL_LIT`配置为`$(which lit)`即可。
+
+```shell
+cmake -G Ninja -DMLIR_DIR=$LLVM_DIR/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$(which lit) ..
+ninja test-standalone

+ 如何使用`MSBuild`将构建过程中生成文件复制到生成目录中？
+
+<!--more-->
+
+### 遇到的问题
+
+最近在尝试在`blazor`项目中使用`tailwindcss`作为`css`工具类的提供工具，而不是使用老旧的`bootstrap`框架，不过使用`tailwindcss`需要在项目构建时使用`tailwindcss`工具扫描文件中使用到的`css`属性并生成最终的`css`文件，这就带来了在构建时运行`tailwindcss`生成并复制到输出目录的需求。
+
+由于我是使用`pnpm`作为前端管理工具，我在项目的`csproj`文件中添加了下面的`Target`来生成文件：
+
+```xml
+<Target Name="EnsurePnpmInstalled" BeforeTargets="BeforeBuild">
+    <Message Importance="low" Text="Ensure pnpm is installed..."/>
+    <Exec Command="pnpm --version" ContinueOnError="true">
+      <Output TaskParameter="ExitCode" PropertyName="ErrorCode"/>
+    </Exec>
+
+    <Error Condition="$(ErrorCode) != 0" Text="Pnpm is not installed which is required for build."/>
+
+    <Message Importance="normal" Text="Installing pakages using pnpm..."/>
+    <Exec Command="pnpm install"/>
+  </Target>
+
+  <Target Name="TailwindGenerate" AfterTargets="EnsurePnpmInstalled" BeforeTargets="BeforeBuild">
+    <Message Importance="normal" Text="Generate css files using tailwind..."/>
+     <Exec Command="pnpm tailwindcss -i wwwroot/tailwind.css -o wwwroot/tailwind.g.css"/>
+  </Target>
+```
+
+这套生成逻辑在本地工作良好，但是却在CI上运行时出现了问题：`CI`上打包的`Docker`镜像中没有`tailwind.g.css`文件，导致最终部署的站点丢失了所有的格式。
+
+### 产生问题的原因
+
+经过反复实验，我发现只有在构建之前`wwwroot`目录中已经存在`tailwind.g.css`文件的情况下，`MSBuild`才会将生成的文件复制到最终的输出目录中。但是在`CI`环境下，因为使用`.gitignore`没有将`*.g.css`文件添加到代码管理，因此`CI`运行构建之前没有该文件，因此构建的结果中也没有该文件。
+
+仔细研究`MSBuild`的文档和网络上的[分享](https://gist.github.com/BenVillalobos/c671baa1e32127f4ab582a5abd66b005)，我意识到这是由于`MSBuild`的构建流程导致的，MSBuild`的构建流程分成两个大的阶段：
+
+- 评估阶段（Evaluation Phase）
+
+  在这个阶段，`MSBuild`将会运行读取所有的配置文件，创建需要的属性，展开所有的`glob`，建立好整个构建流程。
+
+- 执行阶段（Execution Phase）
+
+  在这个阶段，`MSBuild`将按照上一阶段执行的属性执行实际的构建指令。
+
+这两个阶段的划分就导致在生成阶段才生成的文件不会被包含在复制文件的指令中，因此他们不会被拷贝到最终的输出目录中。
+
+>这和`cmake`的构建过程很像，首先调用`cmake`生成一些构建指令，在调用实际的构建指令构建二进制文件。
+
+因此这类问题的推荐解决办法是手动将这些文件添加到构建流程中，即在`BeforeBuild`目标调用之前使用`Content`和`None`等项。
+
+### 解决问题
+
+总结上述的解决问题方法，我在上面的构建流程中添加了如下的`None`项：
+
+```xml
+<Target Name="EnsurePnpmInstalled" BeforeTargets="BeforeBuild">
+    <Message Importance="low" Text="Ensure pnpm is installed..."/>
+    <Exec Command="pnpm --version" ContinueOnError="true">
+      <Output TaskParameter="ExitCode" PropertyName="ErrorCode"/>
+    </Exec>
+
+    <Error Condition="$(ErrorCode) != 0" Text="Pnpm is not installed which is required for build."/>
+
+    <Message Importance="normal" Text="Installing pakages using pnpm..."/>
+    <Exec Command="pnpm install"/>
+  </Target>
+
+  <Target Name="TailwindGenerate" AfterTargets="EnsurePnpmInstalled" BeforeTargets="BeforeBuild">
+    <Message Importance="normal" Text="Generate css files using tailwind..."/>
+    <Exec Command="pnpm tailwindcss -i wwwroot/tailwind.css -o wwwroot/tailwind.g.css"/>
+
+    <!-- Make sure generated file will be copied to output directory-->
+    <ItemGroup>
+      <Content Include="wwwroot/tailwind.g.css" Visible="false" CopyToOutputDirectory="PreserveNewest"/>
+    </ItemGroup>
+  </Target>
+```
+
+在运行构建之后，在最终的`publish`文件夹的`wwroot`文件夹中就可以找到`tailwind.g.css`文件。
+
+不过我还想进行一点优化，`MSBuild`文档中建议将自动生成的文件放在`IntermediateOutputPath`，也就是`obj`文件加中，因此这里尝试将`tailwind.g.css`文件生成到`IntermediateOuputPath`中，优化之后的`Target`项长这个样子：
+
+```xml
+  <Target Name="EnsurePnpmInstalled" BeforeTargets="BeforeBuild">
+    <Message Importance="low" Text="Ensure pnpm is installed..."/>
+    <Exec Command="pnpm --version" ContinueOnError="true">
+      <Output TaskParameter="ExitCode" PropertyName="ErrorCode"/>
+    </Exec>
+
+    <Error Condition="$(ErrorCode) != 0" Text="Pnpm is not installed which is required for build."/>
+
+    <Message Importance="normal" Text="Installing pakages using pnpm..."/>
+    <Exec Command="pnpm install"/>
+  </Target>
+
+  <Target Name="TailwindGenerate" AfterTargets="EnsurePnpmInstalled" BeforeTargets="BeforeBuild">
+    <Message Importance="normal" Text="Generate css files using tailwind..."/>
+    <Exec Command="pnpm tailwindcss -i wwwroot/tailwind.css -o $(IntermediateOutputPath)tailwind.g.css"/>
+
+    <!-- Make sure generated file will be copied to output directory-->
+    <ItemGroup>
+      <Content Include="$(IntermediateOutputPath)tailwind.g.css" Visible="false" TargetPath="wwwroot/tailwind.g.css"/>
+    </ItemGroup>
+  </Target>
+```
+
+经过测试，这套生成逻辑在`blazor`类库环境下也可以正常运行，类库的文件会被正确地生成到`wwwroot/_content/<ProjectName>/`文件夹下面。
