* pa-linux.h (INCOMING_RETURN_ADDR_RTX): Move.
	(DWARF_FRAME_RETURN_COLUMN): Move.
	(ASM_PREFERRED_EH_DATA_FORMAT): Define.
	(ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX): Define.
	* pa.c (except.h, predict.h): Include.
	(FRP): Delete.
	(store_reg_modify, set_reg_plus_d): Revise prototypes.
	(output_ascii): Add cast.
	(store_reg_modify): Revise to add frame notes.
	(set_reg_plus_d): Likewise.
	(compute_frame_size): Include space for eh data registers in frame if
	the current function calls eh_return.
	(hppa_expand_prologue):  Ensure register %r2 is saved if the current
	function calls eh_return.  Save eh data registers if the current
	function calls eh_return.  Fix code to add frame notes.  Emit
	blockage to prevent insns with frame notes being scheduled in the
	delay slot of calls.
	(hppa_expand_epilogue): Restore eh data registers and do final stack
	adjustment if the current function calls eh_return.  Don't add frame
	notes.
	(output_call): Revise for change in length of call insn.  Don't do
	return pointer adjustment for an unconditional jump in the delay slot
	of a call when using frame notes.
	* pa.h (EH_RETURN_DATA_REGNO): Revise for TARGET_64BIT compatibility.
	(EH_RETURN_HANDLER_RTX): Use saved value on stack.
	(ARG_POINTER_CFA_OFFSET): Define.
	* pa.md (return_external_pic): New pattern.
	(prologue): Correct formatting.  Use return_external_pic if current
	function calls eh_return.
	(call_internal_symref, call_value_internal_symref,
	sibcall_internal_symref, sibcall_value_internal_symref): Change default
	lengths of short, long non-pic, and long pic calls to 8, 68, and 84,
	respectively.
	(exception_receiver): Use hppa_pic_save_rtx () to restore pic register.

	* configure.in ("assembler dwarf2 debug_line support"): Add hppa*-*-* to
	list of targets to check using "nop" insn.
	* configure: Rebuilt.
