The general position with regard to proprietary software (which LLVM
isn't, but there can be proprietary variants) is that we don't want to
support functionality that isn't supported by free software in order not
to provide an incentive to use non-free software.

Now anything supporting the free LLVM variant does not force one to use
non-free software, so the rule does not really apply.  However, we still
want to have people prefer GNU software over GPLed software, and GPLed
software over non-copylefted software, so this case may be considered
somewhat analogous.

In this particular case, gdb is already fully supported.  So my opinion
would be, for what it's worth, that "basic lldb support" should be
unproblematic as long as it does not involve functionality absent from

Naturally, it's best to wait what Richard has to say on that.
