3 years ago Herzliche Grüsse aus Baden-Württemberg, as you didn't take the trouble to say.
The runtime (and especially the garbage collector) relies on using 32-bit pointers. There's a workaround that works on Linux/amd64 by arranging to allocate storage in the bottom 2GB of the address space -- it's enabled in the source by the ifdef M64X32. Perhaps the same will work in Linux/AArch64 if the mmap supports the MAP_32BIT flag. Would you like to paste the man page for mmap here?
This will give us a version of OBC that relies on a bytecode interpreter. It would be more work to write a JIT translator for AArch64. I haven't looked into it myself, but there is already a JIT for 32-bit ARM -- is that called AArch32 now?
