	branch_dest.  Use get_frame_pc instead of read_pc.
	(rs6000_software_single_step): Likewise.
	(bl_to_blrl_insn_p): Do not call branch_dest.
	* rs6000-tdep.h (rs6000_software_single_step): Replace REGCACHE
	argument by FRAME.

	* sparc64-linux-tdep.c (sparc64_linux_step_trap): Add FRAME argument.
	Read registers from FRAME instead of current regcache.

	GDBARCH.  Pass FRAME to step_trap callback.
	(sparc_step_trap): Add FRAME argument.
	(space_software_single_step): Replace REGCACHE by FRAME.  Pass FRAME
	to sparc_analyze_control_transfer.  Read registers from FRAME instead
	of calling sparc_address_from_register.
	* sparc-tdep.h (struct gdbarch_tdep): Add FRAME argument to
	step_trap callback.
	(sparc_address_from_register): Remove prototype.
	(sparc_software_single_step): Replace REGCACHE argument by FRAME.
