- Look for “ClangDefaultVersion” and/or “clang-” in build/soong/cc/config/global.go.
  - AOSP Code Search link
Android Platform LLVM binutils
- Currently clang-r510928
- These are symlinks to llvm tools and can be updated by running update-binutils.py.

  - Look for “clang-” in android15-6.1 build configs
- When adding or removing a clang prebuilt, the list in kleaf/versions.bzl needs to be updated.
- Internal LLVM developers should look in the partner gerrit for more kernel configurations.

- Currently clang-r487747c
- Linux emulator is temporarily hardcoded to clang-r487747c, see b/268674933
- Look for “clang-” in external/qemu/android/build/toolchains.json.
  - Note that they work out of the emu-master-dev branch.

Stage 1 compiler
- Currently clang-r510928
- Look for “clang-r” in toolchain/llvm_android/constants.py
