sparc64 work.

  • Modify before_thread_runs_arch() to store addresses of the kernel stack and

userspace window buffer, resp., to registers %g6 and %g7, resp, in the
alternate and interrupt global sets.

  • Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
  • Implement trap handler for spilling register windows into userspace window buffer.
  • Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
  • Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,

spill_0_other and fill_1_normal handlers. These handlers are used in different situations
and for different purposes.
  • Property mode set to 100644
