Hey everyone, I've got some preliminary but functioning work in place in order to support self-debugging. Immediately forthcoming is two patches, summarized below, which implement basic support for self-debugging on Linux. I've leveraged the ProcessMonitor architecture on Linux in order to do this, so the first patch is a refactor of ProcessMonitor to allow me to create a different implementation of it. The second patch actually fills in the self-debugging implementation.
[PATCH 1/2] Refactor ProcessMonitor into an abstract base class. [PATCH 2/2] Support debugging yourself on Linux. There's still some issues: * I needed to disable JITLoaderGDB [1] in order to prevent lldb from attempting to set a breakpoint at attach. I'm also not clear on what JITLoaderGDB does even after perusing the code, so I'm not sure if disabling it is the right thing to do. * I needed to disable LLDB copying it's stdin to it's inferior's [1] as it would result in multiple threads reading from stdin - making it impossible to use the prompt. This behavior makes sense to me if the debugee is launched from LLDB, but I'm not clear on why LLDB attempts to do it when you've attached to your debugee. * "thread list" returns nothing. I think there's a larger problem here. Needs investigation.
