I want to know if is possible to use the LLVM debugger with the Emacs, something like the M-x gdb interface standard. Thanks in advance.
Adding LLVM debugger support to Emacs is surprisingly (or not, depending on your level of cynicism) contentious.
In February, 2015, Richard Stallman wrote:
The LLVM source repository includes a patch adding basic lldb support to gud.el.
It looks like there is a systematic effort to attack GNU packages. The GNU Project needs to respond strategically, which means not by having each GNU package cooperate with each attack. For now, please do NOT install this change.
Stefan Monnier, one of the current maintainers, is much less hostile to the change:
Thanks, Andrew. I'd be happy to incorporate such a patch. I took a quick look at the code, and seen from afar, there's no problem with it, so all that is really needed is to clear the copyright status of this code.
As of March, 2015, I don't believe that the LLVM debugger patch has been accepted.
