If building on Linux, pass
--no-build windows to
build.py to skip building Clang for Windows.
If you have an additional llvm tree built and present in your
build.py might fail during the Windows build of libcxxabi with the error

To rebuild a particular toolchain, find the manifest file for that release:
$ $TOOLCHAIN_DIR/bin/clang -v Android (6317467 based on r365631c1) clang version 9.0.8...
The build number for that toolchain is
6317467 and the manifest is found in
Rebuild the toolchain with that manifest:
$ mkdir llvm-toolchain && cd llvm-toolchain $ repo init -u https://android.googlesource.com/platform/manifest -b llvm-toolchain $ cp $TOOLCHAIN_DIR/manifest_6317467.xml .repo/manifests $ repo init -m manifest_6317467.xml $ repo sync -c # Optional: Apply any LLVM/Clang modifications to toolchain/llvm-project $ python toolchain/llvm_android/build.py
