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.
