Sorry, I did not see this until this morning, and at the moment have no active 64b hardware, so cannot bootstrap (replacement needs commissioning). However, this affects the build so the cross seems fine. I see you already landed the fix and I’ve confirmed a local cross works post that .. will queue a powerpc-darwin9 build for later, thanks Iain >> >> Thanks and regards, >> Avinash Jayakar >> >> Darwin maintains a separate array of register_names where the Dense Math >> Registers were not added.
