  // Funny Darwin hack: This flag tells the linker that no global symbols

  // contain code that falls through to other global symbols (e.g. the obvious

  // implementation of multiple entry points).  If this doesn't occur, the

  // linker can safely perform dead code stripping.  Since LLVM never generates

  // code that does this, it is always safe to set.
