In the llgs world, ProcessWindows will eventually go away and we'll implement a different protocol. This patch decouples ProcessWindows from the core debug loop so that this transition will not be more difficult than it needs to be. llvm-svn: 221405

// LocalDebugDelegate
|
|
//
|
|
// LocalDebugDelegate creates a connection between a ProcessWindows and the
|
|
// debug driver. This serves to decouple ProcessWindows from the debug driver.
|
|
// It would be possible to get a similar decoupling by just having
|
|
// ProcessWindows implement this interface directly. There are two reasons why
|
|
// we don't do this:
|
|
//
|
|
// 1) In the future when we add support for local debugging through LLGS, and we
|
|
// go through the Native*Protocol interface, it is likely we will need the
|
|
// additional flexibility provided by this sort of adapter pattern.
|
|
// 2) LLDB holds a shared_ptr to the ProcessWindows, and our driver thread also
|
|
// also needs access to it as well. To avoid a race condition, we want to
|
|
// make sure that we're also holding onto a shared_ptr.
|
|
// lldb_private::Process supports enable_shared_from_this, but that gives us
|
|
// a ProcessSP (which is exactly what we are trying to decouple from the
|
|
// driver), so this adapter serves as a way to transparently hold the
|
|
// ProcessSP while still keeping it decoupled from the driver.
