After a little research it looks like aarch64 (Arm ARCHitecture 64-bit) is the official name. ARM64 comes from the previously closed source llvm backend for aarch64 made by Apple: https://www.phoronix.com/scan.php?page=news_item&px=MTY5ODk https://www.phoronix.com/scan.php?page=news_item&px=MTY5ODk, but is now used as shorthand, like x64.
- cellularmitosis 6y ago> like x64 I seem to recall reading somewhere that "x64" actually referred to something which was distinct from x86_64 (was it a special mode of using 32-bit pointers with a 64-bit kernel? I can't remember exactly now), but now that I am googling for it, I can't seem to find anything.
