I have been using Python target for Antlr4. Now I am planning to move to cpp as Antlr4 has support for cpp as the target language. Wanted to know if there are any major bugs/ performance issues etc with using cpp as the target language (since it's just been introduced recently)?
Links I have referred so far,

I recently wrote an entire programming language using ANTLR. It took quite a bit of work upfront, but my grammar became very flexible afterwards. I haven't noticed any performance issues.
If you want a more gentle introduction to ANTLR on C++, I wrote a simple calculator example that has all of the set-up.

The cmake in antlr repository is not perfect, if you can use Linux packages. I do remember seeing many suboptimal and potentially broken things in cpp runtime year ago.
However as a user I did not experience any problems, performance issues only from wrong grammars.
If you are planing to use cmake this may come handy (cmake script for automatic generating of a parser from .g4).
