Subject: 	* gdbarch.sh (software_single_step): Replace REGCACHE argument
 by 	FRAME argument. 	* gdbarch.c, gdbarch.h: Regenerate. 	*
 infrun.c (resume): Pass current frame to SOFTWARE_SINGLE_STEP.

	* alpha-tdep.c (alpha_next_pc): Add FRAME argument.  Retrieve
	registers from FRAME instead of using read_register.
	(alpha_software_single_step): Replace REGCACHE by FRAME.  Pass FRAME
	to alpha_next_pc.  Use get_frame_pc instead of read_pc.
	* alpha-tdep.h (alpha_software_single_step): Replace REGCACHE
	argument by FRAME.

	* arm-tdep.c (shifted_reg_val): Add FRAME argument.  Read registers
	from FRAME instead of using read_register.
	(thumb_get_next_pc): Likewise.
	(arm_get_next_pc): Likewise.
	(arm_software_single_step): Replace REGCACHE by FRAME.  Pass FRAME
	to arm_get_next_pc.  Use get_frame_pc instead of read_register.
	* arm-tdep.h (arm_software_single_step): Replace REGCACHE
	argument by FRAME.

	* cris-tdep.c (find_step_target): Add FRAME argument.  Read registers
	from FRAME instead of using read_register.
	(cris_software_single_step): Replace REGCACHE by FRAME.  Pass FRAME
	to find_step_target.

	* mips-tdep.c (mips32_next_pc): Add FRAME argument.  Read registers
	from FRAME instead of using read_register / read_signed_register.
	(extended_mips16_next_pc): Likewise.
	(mips16_next_pc): Likewise.
	(mips_next_pc): Likewise.
	(mips_software_single_step): Replace REGCACHE by FRAME.  Pass FRAME
	to mips_next_pc.  Use get_frame_pc instead of read_pc.
	* mips-tdep.h (mips_software_single_step): Replace REGCACHE
	argument by FRAME.

	* rs6000-tdep.c (branch_dest): Add FRAME argument.  Use it instead
	of current frame.  Read registers from FRAME.
	(deal_with_atomic_sequence): Add FRAME argument.  Pass it to
	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.
	* sparc-linux-tdep.c (sparc32_linux_step_trap): Likewise.
	* sparcnbsd-tdep.c (sparcnbsd_step_trap): Likewise.
	* sparc-tdep.c (sparc_address_from_register): Remove.
	(sparc_analyze_control_transfer): Pass FRAME argument instead of
	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.
	(sparcnbsd_step_trap): Add FRAME argument.

	* spu-tdep.c (spu_software_single_step): Replace REGCACHE argument
	by FRAME.  Read registers from FRAME instead of REGCACHE.
