As Pavel mentioned, the code has a definite LLDB feel to it, but more importantly it depends on StringExtractor which I think probably doesn't belong in LLVM.  If you want to go down this route, I would start by deleting the StringExtractor changes from this CL.  90% of the stuff StringExtractor is used for, like hex string to number, string to integer, etc are covered by existing LLVM classes or methods.


My rationale was that reusing parser from a child project is better than building anything new from scratch.

I can't actually find json parser within clang-tidy. Only references that I see lead eventually to YAML parsing:
