The LuaJIT maintainer is missing that Apple does not claim any conformance to ARM EABI. Apple's ABI is defined to be based on the AAPCS standard, but Apple makes no claims to it being exact.

In other words, it's not Linux, and it sounds like the LuaJIT maintainer is annoyed that it doesn't follow a common approach used on Linux.

Anyone that works on low-level implementations that sit below the standard platform compiler should expect this kind of thing when supporting multiple platforms.
