/* For BSD:

   The signal context structure pointer is always saved at the base
8
   of the frame + 0x4.

   We get the PC & SP directly from the sigcontext structure itself.
11
   For other registers we have to dive in a little deeper:

13
   The hardware save state pointer is at offset 0x10 within the
14
   signal context structure.

16
   Within the hardware save state, registers are found in the same order
17
   as the register numbers in GDB. */
