- Provide `Check::Dump(context, arg)` and similar. - gdb and lldb should do contextual lookup, and `call Dump(*this, Lex::TokenIndex::Invalid)` has been tested with gdb. - Since this is only for debug, keeps the functions fully separated from code. - Uses alwayslink to ensure objects are correctly linked, even though there are no calls. - `-Wno-missing-prototypes` is needed when we don't have forward declarations. - Code is not linked in opt builds, using `#ifndef NDEBUG`. - This probably could be doing something in BUILD files with a `select()`, but the `#ifndef` seemed easier. This is based on #4620, but uses free functions instead of member functions. Co-authored-by: Dana Jansens <danakj@orodu.net> --------- Co-authored-by: danakj <danakj@orodu.net>
