at the moment there is no JIT support for 64-bit and in result no debug metadata ( JITMetadata from core.cfg in sourcemod)
having some kind of debug metadata on x64 would be quite helpful although I am not sure how viable it is performance wise on non-JIT
What sort of info are you after from it? I don't think any of the standard stuff could work with interpreter stacks, but they should already have relevant info available.
