(sparc64_supply_rwindow, sparc64_fill_rwindow): Remove prototypes. (sparc_supply_rwindow, sparc_fill_rwindow): New prototypes. * sparc64-tdep.c (sparc64_pseudo_register_read): Add missing `case' keyword. (sparc64_register_info): Give the reister with number SPARC64_STATE_REGNUM a name. (sparc64_pseudo_register_write): Add support for %cwp, %pstate, %asi and %ccr. (sparc64_push_dummy_call): Take BIAS into account when checking stcak alignment. (sparc_software_single_step): Remove assertions that check whether NPC and NNPC were zero. (sparc_supply_rwindow): Make public. Merge functionality with sparc64_supply_rwindow. (sparc_fill_rwindow): Make public. Merge functionality with sparc64_fill_rwindow. (sparc64_supply_rwindow, sparc64_fill_rwindow): Remove. * sparc64fbsd-nat.c (_initialize_sparc64fbsd_nat): Set SPARCBSD_FPREG_SUPPLIES_P to sparc64fbsd_fpreg_supplies_p. * sparc64fbsd-tdep.c (sparc64fbsd_supply_reg): Call sparc_supply_rwindow instead of sparc64_supply_rwindow.
