-
- The signal context structure pointer is always saved at the base
- of the frame which "calls" the signal handler. We only want to find
- the hardware save state structure, which lives 10 32bit words into
- sigcontext structure.
-
- Within the hardware save state structure, registers are found in the
- same order as the register numbers in GDB.
-
- The kernel apparently sets %r31 in the saved state structure to point
- to the active instruction when the signal was taken. Everything
- else looks fairly reasonable. (I assume the kernel fixes %r31 from
