(sparc_unwind_dummy_id): Likewise. * sparc64-tdep.c (sparc64_frame_prev_register): Adjust for new frame base address convention. (sparc64_push_dummy_call): Likewise. * sparc64nbsd-tdep.c: Update copyright year. (sparc64nbsd_sigcontext_frame_cache): Adjust cached frame base address for 64-bit code. (sparc64nbsd_init_abi): Tweak comment. * sparc64obsd-tdep.c: Update copyright year. (sparc64obsd_frame_cache): Adjust cached frame base address for 64-bit code.
