| // 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. |
