  33 // This code logically belongs in stacktrace.cc, but
  34 // it is moved into (this) separate file in order to
  35 // prevent inlining of routines defined here.
  36 //
  37 // Inlining causes skip_count to be incorrect, and there
  38 // is no portable way to prevent it.
  39 //
  40 // Eventually LTO (link-time optimization) and/or LLVM
  41 // may inline this code anyway. Let's hope they respect
  42 // ATTRIBUTE_NOINLINE.
