46
   The signal context structure pointer is always saved at the base
47

48
   the hardware save state structure, which lives 10 32bit words into

   sigcontext structure.

   Within the hardware save state structure, registers are found in the

   At one time we peeked at %r31 rather than the PC queues to determine
55
   what instruction took the fault.  This was done on purpose, but I don't
56
   remember why.  Looking at the PC queues is really the right way, and
57
   I don't remember why that didn't work when this code was originally
58
   written.  */
