* The exception table consists of pairs of addresses: the first is the |
|
* address of an instruction that is allowed to fault, and the second is |
|
* the address at which the program should continue. No registers are |
|
* modified, so it is entirely up to the continuation code to figure out |
|
* what to do. |
|
* |
|
* All the routines below use bits of fixup code that are out of line |
|
* with the main instruction path. This means when everything is well, |
|
* we don't even have to jump over them. Further, they do not intrude |
|
* on our cache or tlb entries. |
