core.internal.backtrace.handler

Libunwind-based implementation of TraceInfo

This module exposes an handler that uses libunwind to print stack traces. It is used when druntime is packaged with DRuntime_Use_Libunwind or when the user uses the following in main:

import core.runtime;
import core.internal.backtrace.handler;
Runtime.traceHandler = &libunwindDefaultTraceHandler;

Note that this module uses dladdr to retrieve the function's name. To ensure that local (non-library) functions have their name printed, the flag -L--export-dynamic must be used while compiling, otherwise only the executable name will be available.
