This page describes how to use ThreadSanitizer on Android devices. The instructions are raw. Ideally all that is integrated into llvm/android build systems. But that's what we have now.
download aosp_master by following instructions in https://source.android.com/source/downloading.html
download compiler-rt from github https://github.com/llvmmirror/compilerrt
1. replace aosp_master/external/compiler_rt with compilerrt in upstream.
$mv aosp_master/external/compiler_rt aosp_master_compiler_rt
$cd aosp_master/external
$ln s ../../compiler_rt compiler_rt
2. copy build files from aosp_master compiler_rt to upstream compiler_rt.
$cd aosp_master_compiler_rt
$find . name Android.bp
./Android.bp
./lib/tsan/Android.bp
./lib/profile/Android.bp
./lib/sanitizer_common/Android.bp
./lib/sanitizer_common/tests/Android.bp
./lib/interception/Android.bp
./lib/ubsan/Android.bp
./lib/asan/Android.bp
./lib/lsan/Android.bp
copy all Android.bp from aosp_master_compiler_rt to corresponding directories in upstream compiler_rt. except lib/asan/Android.bp (because it has a wrap file which doesn’t appear in upstream)
$ cp Android.bp ../aosp_master/external/compilerrt/
$ cp lib/tsan/Android.bp ../aosp_master/external/compilerrt/lib/tsan/
$ cp lib/profile/Android.bp ../aosp_master/external/compilerrt/lib/profile/
$ cp lib/sanitizer_common/Android.bp ../aosp_master/external/compilerrt/lib/sanitizer_common/
$ cp lib/interception/Android.bp ../aosp_master/external/compilerrt/lib/interception/
$ cp lib/ubsan/Android.bp ../aosp_master/external/compilerrt/lib/ubsan/
$ cp lib/lsan/Android.bp ../aosp_master/external/compilerrt/lib/lsan/
3. change build files add following lines in lib/tsan/Android.bp, and remove tests build:

4. bulid libtsan_shared.so
$cd aosp_master
$. build/envsetup.sh
$lunch aosp_arm64userdebug
$mmma external/compilerrt/lib/tsan j30
after building successfully, libtsan_shared.so for aarch64 is in aosp_master/out/target/product/generic_arm64/system/lib64/libtsan_shared.so
5. Link app with libtsan_shared.so Then you can use tsan by link libtsan_shared.so. Note that libtsan_shared.so only works with libc.so on N devices or built in aosp_master. So you may need to find a way to link libc.so built in aosp_master instead of the one running on device.
6. you may also need to build llvm-symbolizer and download llvm-symbolizer on device.
