For examples, take a look at the related code in the LLVM tools:

tools/clang/lib/CodeGen/BackendUtil.cpp
tools/opt/opt.cpp
tools/llc/llc.cpp

  // Add an appropriate TargetLibraryInfo pass for the module's triple.
  TargetLibraryInfo *TLI = new TargetLibraryInfo(TheTriple);
  if (DisableSimplifyLibCalls)
    TLI->disableAllFunctions();
  PM.add(TLI);
