# 构建LLVM指导

在 Arch Linux 上编译 bloomberg/clang-p2996 小记

https://zzhx2006.github.io/blog/compiling-clang-p2996-on-arch-linux/

```shell
git clone https://github.com/bloomberg/clang-p2996 --depth 1 --branch=p2996
cd clang-p2996
mkdir build
cd build
```

```shell
laozu@laozu-Virtual-Machine:~/code/clang-p2996/build$ cmake -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_ENABLE_RUNTIMES="libc;libcxx;libcxxabi;libunwind" -DCMAKE_C_FLAGS="-O3 -march=native -mtune=native" -DCMAKE_CXX_FLAGS="-O3 -march=native -mtune=native" -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_TOOLS=OFF -DLLVM_BUILD_EXAMPLES=OFF -DLLVM_BUILD_TESTS=OFF -DLLVM_INCLUDE_TESTS=OFF -DLLVM_INCLUDE_DOCS=OFF -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-build -G "Unix Makefiles" ../llvm
```

windows版使用x64 Native Tools Command Prompt for VS 2022

注意：windows命令行不一定全对
```shell
cmake -Wno-dev ^
-DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ^
-DCMAKE_BUILD_TYPE=Release ^
-DCMAKE_C_FLAGS="/O2" ^
-DCMAKE_CXX_FLAGS="/O2" ^
-DLLVM_BUILD_TOOLS=OFF ^
-DLLVM_BUILD_EXAMPLES=OFF ^
-DLLVM_BUILD_TESTS=OFF ^
-DLLVM_INCLUDE_TESTS=OFF ^
-DLLVM_INCLUDE_DOCS=OFF ^
-DLLVM_TARGETS_TO_BUILD="X86" ^
-DCMAKE_INSTALL_PREFIX="C:\llvm-build" ^

../llvm
