/* 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.
