[llvm-dev] lldb-mi support for GNU emacs

[Adrian Prantl via llvm-dev]

As Mehdi said, the LLDB mailing list is the better place to ask this question.

The subset of MI commands that lldb-mi currently understands is very narrow and was added to support one specific consumer (I think it might have been Eclipse, but I could be misremembering). In any case, it looks like lldb-mi is missing the implementation for certain MI commands that Emacs is expecting. Adding these shouldn't be too much work if you're building on top of the LLDB scripting API.
