我想用ASAN构建LLVM。文档说明使用LLVM_USE_SANITIZERS。那没用我试过不同的组合旗，浪费了很多时间搜索，但一无所获。我尝试的最后一个是：
cmake -G Ninja ../llvm \
-DCMAKE_INSTALL_PREFIX=/home/mikadore/local/llvm15-debug \
-DCMAKE_BUILD_TYPE=Debug \
-DLLVM_ENABLE_PROJECTS='lld;clang;clang-tools-extra;compiler-rt' \
-DLLVM_USE_RUNTIMES='compiler-rt' \
-DLLVM_ENABLE_LIBXML2=OFF \
-DLLVM_ENABLE_TERMINFO=OFF \
-DLLVM_ENABLE_LIBEDIT=OFF \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DLLVM_USE_SANITIZER='Address;Undefined' \
-DCMAKE_CXX_COMPILER=clang++ \
-DCMAKE_C_COMPILER=clang我还将compiler-rt从llvm-project复制到llvm子文件夹中。但它们都失败了，都犯了同样的错误：

消毒器，包括ASAN，实际上是compiler-rt项目的一部分，该项目包含消毒器库，包括在启用消毒器时在编译时插入到代码中的消毒器函数（在使用ASAN的情况下为
__asan_函数）。我能够使用CMake构建启用ASAN的LLVM 16：
