- /* Parameters for execution on an HP PA-RISC machine running OSF1, for GDB.

- University of Utah (pa-gdb-bugs@cs.utah.edu). */

- /* For OSF1 (Should be close if not identical to BSD, but I haven't
- tested it yet):
-
- The signal context structure pointer is always saved at the base
- of the frame + 0x4.
-
- We get the PC & SP directly from the sigcontext structure itself.
- For other registers we have to dive in a little deeper:
-
- The hardware save state pointer is at offset 0x10 within the
- signal context structure.
-
- Within the hardware save state, registers are found in the same order
- as the register numbers in GDB. */
