10 // Due to C++17 inline variables ASAN flags this test as containing an ODR
11 // violation because Clock::is_steady is defined in both the dylib and this TU.
14 // Starting with C++17, Clock::is_steady is inlined (but not before LLVM-3.9!),
15 // but before C++17 it requires the symbol to be present in the dylib.
