◆ CrashHandler()

CrashHandler - This callback is run if a fatal signal is delivered to the process, it prints the pretty stack trace.
Definition at line 105 of file PrettyStackTrace.cpp.

◆ LLVMEnablePrettyStackTrace()
| void LLVMEnablePrettyStackTrace | ( | void | ) |
Enable LLVM's built-in stack trace code.
This intercepts the OS's crash signals and prints which component of LLVM you were in at the time if the crash.
