The historical LLP64 and LLP64-v2 on https://github.com/OpenSmalltalk/opensmalltalk- have been integrated back in Cog branch for some time now (by way of cherry-picking).vm/branches
They won't be merged (they can't because of generated VMMaker code).They served for building a win64 artifact in 2016. But this artifact is obsolete IMO.
Does anybody mind if I delete them?
