-// Fake Address Sanitizer run-time support.
-// Enough for programs to link and run, but will not find any errors.
-// Also, linking this to shared libraries voids the warranty.
-//
-// We need this fake thunks if we build Chrome with ASAN support because
-// pyautolib DSO is instrumented with ASAN and is loaded to regular python
-// process that has no ASAN runtime.
-//
-// We have three options here:
-// 1) use our custom build of Python that have ASAN runtime linked in,
-// 2) do not instrument pyautolib with ASAN support,
-// 3) use this fake asan thunks linked to pyautolib so that instrumented code
-//    does not complain.
-//
-// Note that we should not use real ASAN runtime linked with DSO because it will
-// not have information about memory allocations made prior to DSO load.
-//
-// Option (2) is not easy because pyautolib uses code from Chrome
-// (see chrome_tests.gypi, dependencies for target_name: pyautolib) that
-// has been instrumented with ASAN. So even if we disable -sanitize=address
-// for pyautolib own sources, ASAN instrumentation will creep in from there.
-// To avoid ASAN instrumentation, we might force Chrome build to compile all our
-// dependencies one more time without -fsanitize=address.
-//
-// Note also that using these empty stubs prevents ASAN from catching bugs in
-// Python-pyautolib process. But we do not need it, we are interested in Chrome
-// bugs.
