OK, you reminded me of this. The x87 FP interface is still inspired by this old interface. FP exceptions were signaled not on the original instruction that caused the exception, but on the next FP instruction (just before it started executing). Which might be a long way off. By the time I started paying attention to x86, the ISA provided everything necessary to fix up such delayed exceptions: * FIP, the IP of the instruction that caused the exception * FOP, it's opcode * FEA, the effective address of the memory operand Q: I think that these features were present in the original x87, but unfortunately I have packed up those manuals and Now, you could simply take an FP exception, do nothing, and return. But if you wanted to emulate any features of the instruction, you would have to interpret FIP/FOP/FEA. Asynchronous interrupts that entered and returned? Not a problem IIRC, so long as they did not do FP, and obtain such a delayed FP exception. What if you wanted to use FP in the interrupt handler? Or context switch to a new process? Basically, you would have to drain any pending interrupt like this. I can't remember if there was a standard way to reload the state of FIP/FOP/FEA when context switching to a new process, or returning from an FP using interrupt. Can somebody remind me? IIRC the SMI, system management interrupt introduced for power management was the first interrupt to provide a way of saving and restoring FIP/FOP/FEA. I'm pretty sure that virtual machines do this in the VMCS. --- Things were complicated by the fact that the original x87s were wired up incorrectly. (Or, kluged to make up for pin architecture deficiencies.) Instead of producing a true x87 FP exception, they signalled such problems through an external interrupt. I can't remember how this interacted with FIP/FOP/FEA. By the time I was at Intel it was well enough behaved, but I can easily imagine that it might have broken when x87s were first hooked up to 8086s, or thereabouts. === Anyway: if I am remembering accurately, and if this is what you were referring to, Nick, then I think that it is relevant that this mess arose not because of asynchronous interrupts, but because of an optimization for semi-synchronous, deferred synchronous, exceptions. And possibly because FIP/FOP/FEA were not always treated as first class state. Here's my line in the sand: there must be a clean definition of architectural state. Anything that influences the results of execution, the data values, should be architectural state. And it should be possible to save/restore all such state. --- I also am not terribly fond of deferred exceptions. I am not terribly fond of an interrupt handler or exception handler having to emulate in SW some instructions. It's better to be able to return to a single instruction pointer, and have everything start up again. But if you are going to have to emulate instructions, then that should be a standard facility, a library function. And, as I have mentioned before, I think that there might be some ISA support to make decoding and emulation of instructions like this more portable - so that new instructions can be added to machines that will run old OSes.
