That's fascinating. How does it do so? I thought it only separated the address space into user space and OS space.
- coliveira 5y agoI imagine that this was possible because the compiler had help from the AS400 architecture. In other words, doing this for a complex architecture like i64 would be much more difficult.
- pjmlp 5y agoModern AS/400 runs on PowerPC, the hardware is completly different from the early 1980's models.
- tambourine_man 5y agoI understand the ISA abstraction. That’s pretty common. I’m interested in how the compiler ensures process isolation.
