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