RegisterContextCoreLinux_x86_64 inherits from RegisterContextLinux_x86_64 which inherits from RegisterContext_x86_64 which uses has:
ProcessMonitor &GetMonitor();
This register context used by the core file can't use this since the process plug-in will be ProcessElfCore and the implementation of GetMonitor() does:
ProcessMonitor &
RegisterContext_x86_64::GetMonitor()
{
ProcessSP base = CalculateProcess();
ProcessPOSIX *process = static_cast<ProcessPOSIX*>(base.get());
return process->GetMonitor();
}
ProcessELFCore doesn't, nor should it inherit from ProcessPOSIX and any call to GetMonitor() will fail for ELF core files.
Suggested cleanups:
- Make a register context class that is a base class that doesn't have any reading smarts, then make one that uses ProcessPOSIX and the has the GetMonitor() call, and one that gets its data straight from the core file.
