I don't know.

You mean LLDB support in Creator?

Peu à peu. Slower than hoped for, faster than expected...

You can check out the 2.8 branch at any time to see the current state,
but it's not yet ripe for production.

The main obstacle currently is basic event handling, I don't seem to be
able find a robust method to get hold of _all_ interesting events with
one approach.

_If_ the process starts and properly stops, either by breakpoint or
interrupt, it's rather nice. The LLDB interface to access state and data
is very rich, there's no need to jump through hoops there.

Thanks to Python's "duck typing" it looks like we can re-use most of the
data dumpers unchanged, or mostly unchanged.  QString, QList, std::vector,
std::string work already, I haven't really looked at the rest yet.

Of course, there's a lot of missing features (on the integration side, not
on what LLDB could provide) The disassembler view is very basic, stepping
there doesn't work yet, module list needs a manual kick, no thread
switching yet, etc etc. But most of those features will only translate to
a handful lines of code each, so this part is more grunt work than rocket

In any case, we will have "something" for 2.8 Final. How this "something"
will compare to the GDB interface depends pretty much on whether the event
handling can be stabilized in time.

[And this is, "of course", Mac-only. LLDB on Linux seems to be stuck
somewhere between non-compilable and non-functional, depending on the
exact phase of the moon]
