Description
https://developer.apple.com/documentation/apple_silicon/addressing_architectural_differences_in_your_macos_code?language=objc The C++ ABI for Apple silicon matches the ABI for iOS devices, and not the ABI for Intel-based Mac computers. For information about the ABI, see iOS ABI Function Call Guide. https://developer.apple.com/library/archive/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARM64FunctionCallingConventions.html In the generic procedure call standard, all function arguments passed on the stack consume slots in multiples of 8 bytes. In iOS, this requirement is dropped, and values consume only the space required. For example, on entry to the function in Listing 1, s0 occupies 1 byte at sp and s1 occupies 1 byte at sp+1. Padding is still inserted on the stack to satisfy arguments’ alignment requirements This Jira sub-task tracks implementation for interpreter.
