Function Documentation
◆ CrashHandler()
|
static |
This callback is run if a fatal signal is delivered to the process, it prints the pretty stack trace.
Definition at line 146 of file PrettyStackTrace.cpp.
References llvm::errs(), PrintCurStackTrace(), and setCrashLogMessage().
Referenced by RegisterCrashPrinter().
◆ 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.
Definition at line 298 of file PrettyStackTrace.cpp.
References llvm::EnablePrettyStackTrace().
◆ PrintCurStackTrace()
|
static |
Print the current stack trace to the specified stream.
Marked NOINLINE so it can be called from debuggers.
Definition at line 93 of file PrettyStackTrace.cpp.
