请教一个入门问题，如何编译 32 位的 bin ？ 🤣

[LYingSiMon]

我尝试使用如下命令编译了 9.0.1

git clone -b llvm-9.0.1 https://github.com/heroims/obfuscator
cd obfuscator
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -G "MinGW Makefiles" ../
mingw32-make.exe -j7

经过测试他是工作的，但我希望得到 32位的文件，而不是 64位的，请问我该如何修改？ 我尝试了使用 cmake 的 set(CMAKE_C_FLAGS "-m32")，set(CMAKE_CXX_FLAGS "-m32") 但这会导致 build 的时候失败：

CMake Warning at utils/benchmark/CMakeLists.txt:244 (message):
  Using std::regex with exceptions disabled is not fully supported

之后我又尝试了使用 -DCMAKE_GENERATOR_PLATFORM=x86 强制修改平台，但 cmake 会报错：

Generator

    MinGW Makefiles

  does not support platform specification, but platform

    x86

  was specified.

希望得到您的帮助 ，感谢 🙃

环境：Win10，vs2022+clang编译器，cmake 分支：llvm-13.x 代码路径：d:\obfuscator_32 生成32位vs的solution： ①开始菜单里搜索2022，找到"Developer Command Prompt for VS 2022"，打开 ②cd /d d:\obfuscator_32 ③cmake -G "Visual Studio 17 2022" -A Win32 -DLLVM_ENABLE_PROJECTS="clang" -DCMAKE_BUILD_TYPE=Release -DLLVM_INCLUDE_TESTS=OFF -DLLVM_ENABLE_NEW_PASS_MANAGER=OFF ./llvm
