/* These are the jmp_buf registers I could guess. There are 13 registers
 * in the buffer. There are 8 data registers, 6 general address registers,
 * the Frame Pointer, the Stack Pointer, the PC and the SR in the chip. I would
 * guess that 12 is the SR, but we don't need that anyway. 0 and 1 have
 * me stumped. 4 appears to be a5 for some unknown reason. If you care
 * about this, disassemble setjmp to find out. But don't do it with gdb :)
