/* We implement setjmp/longjmp much like the way gcc implements
|
||||||
|
exceptions - we create new stack frames, then switch to them and
|
||||||
|
return. Thus, the two setjmp's below each push all the relevent
|
||||||
|
registers, then copy the whole frame into the buffer (first $sp is
|
||||||
|
moved, then smovf copies the frame itself), and the two longjmps
|
||||||
|
restore $sp, copy the frame back into place, and issue the same
|
||||||
|
return as the setjmp would have used.
|
||||||
|
|
||||||
|
Since the sizes of registers differs between the 16 and 24 bit
|
||||||
|
models, we provide separate implementations for each rather than
|
||||||
|
trying to parameterize them.
|
||||||
|
|
||||||
|
Jump buffer sizes: 21 bytes for 16 bit, 34 bytes for 24 bit.
