Your analysis is correct -- the kernel uses the bitwidth of the tracer (not the tracee) when deciding whether to use the compatibility interface. However, copying the code sounds like a fairly fragile solution. It'd be better to figure out a way to share the code somehow.

The x86 classes don't have this problem because NativeRegisterContextLinux_x86_64 knows how to debug both 32 and 64-bit processes. That may not be the right solution here, but it's one thing you can use for inspiration.
