What order does Exec save the registers on the stack during a context switch?
What order does Exec save the registers on the stack during a context switch?
My guess is D0 through to D7, followed by A0 through to A6, SR, and then A7 stored in the task control block. So should I want to examine the contents of a waiting task's, D0 (for example) I would look at tc_SPReg + 68? Cheers. |
