baohongde	f490b4ddfe	hli: don't spill registers, instead save them to a separate region ... Level 4 interrupt has a chance of preempting a window overflow or underflow exception. Therefore it is not possible to use standard context save functions, as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4). Instead, mask window overflows and save the entire general purpose register file, plus some of the special registers. Then clear WindowStart, allowing the C handler to execute without spilling the old windows. On exit from the interrupt handler, do everything in reverse.	2020-04-17 23:09:50 +08:00
