I am running v8plus binaries, which are a horrible mix of v8 and v9 code.
But you are right, "wim" was deleted for v9. The reason I did the code
the way I did was because the restore_window() function was updating the
register (even on sparc64).
So I guess the real fix is to implement proper save_window() and
restore_window(), and also flush_window(). Then make sure that "ta 3" on
v9 calls the proper flush_window() code.
As a temporary workaround though the patch I posted seems to work.
