  # to get it, but they're unfree. Since LLVM is rather central to the stdenv, we patch out TSAN support so that Hydra
  # can build this. If we didn't do it, basically the entire nixpkgs on Darwin would have an unfree dependency and we'd
  # get no binary cache for the entire platform. If you really find yourself wanting the TSAN, make this controllable by

      The compiler-rt project provides highly tuned implementations of the
      low-level code generator support routines like "__fixunsdfdi" and other
      calls generated when a target doesn't have a short sequence of native
      instructions to implement a core IR operation. It also provides
      implementations of run-time libraries for dynamic testing tools such as
      AddressSanitizer, ThreadSanitizer, MemorySanitizer, and DataFlowSanitizer.
