Antlr4 alternative for Antlr3's `-report` option

[Nathan Burles]

Hi,

I was looking at using Antlr3 with its C++ target and came across the `-report` option, which generates a very handy output file telling me the k-values for each rule as well as backtracking information.

I then found the Antlr4 C++ target, which seems to be working excellently, so am using that instead... is there anything within Antlr4 that can generate such a report? (I can't find an option on the command line, but maybe there's a tool instead?)

Thanks
Nathan
