  14 // GCC in LTO mode interoperates poorly with non-standard libraries that
  15 // provide implementations of compiler intrinsics such as memcpy/memset
  16 // or the stack protector entry points.
  17 //
  18 // By referencing these functions from a non-LTO object that can be passed
  19 // to the linker via the -plugin-opt=-pass-through=-lxxx options, the
  20 // intrinsics are included in the link in a way that allows them to be
  21 // pruned again if no other references to them exist.
