ideas: hw swap-out caller-saved regs so interrupt handler can just be a c function (In reply to Jacob Lifshay from comment #1) > ideas: hw swap-out caller-saved regs so interrupt handler can just be a c > function paul mentioned something about the e300? how it was a software-emulated MMU and consequently there was a bit in the MSR you could set which enabled swapping at exception time of the top 4 GPRs into SPRs *in addition* to SRR0/1 |
