/* Parameters for execution on an HP PA-RISC machine running BSD, for GDB.
Contributed by the Center for Software Science at the
University of Utah (pa-gdb-bugs@cs.utah.edu). */
/* For BSD:
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. */
