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