For this ghc release cycle, I imagine it's ok to stay Arm 32bit only abi. ESP since the apple upstream arm 64 bit stuff for apple hardware hasn't landed in llvm main afaik.
For any new abis for ghc, I really want to be systematic In how we design and test changes. Austin Seipp may have a more accurate / precise opinion since he's spent a lot of time making arm support work this year. Do we need to do anything to support targeting arm 64?
