to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

// 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
|
|
// 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.
