	(ASM_OUTPUT_DWARF_VMS_DELTA: Define new macro.
	* dbxout.c (gcc_debug_hooks): New entry begin_epilogue.
	* debug.c: Likewise.
	* sdbout.c: Likewise.
	* vmsdbgout.c: Likewise.
	* debug.h: Likewise. (dwarf2out_vms_{begin,end}_prologue): Declare.
	* doc/tm.texi (ASM_OUTPUT_DWARF_VMS_DELTA): Document.
	* dwarf2asm.c (dw2_asm_output_vms_delta): New function.
	(ASM_OUTPUT_DWARF_VMS_DELTA): Call it.
	* dwarf2asm.h (dw2_asm_output_vms_delta): Declare.
	* dwarf2out.c (dw_fde_struct): New fields
	dw_fde_vms_{end,begin}_prologue.
	(PROLOGUE_END_LABEL, EPILOGUE_BEGIN_LABEL): New macros.
	(dwarf2out_begin_prologue): Set dw_fde_struct defaults for above.
	(dwarf2out_vms_end_prologue): New function.
	(dwarf2out_vms_begin_epilogue): New function.
	(dw_val_struct): New value dw_val_class_vms_delta.
	(gcc_debug_hooks): New entry begin_epilogue. Set end_prologue,
	begin_epilogue for VMS.
	(AT_vms_delta1, AT_vms_delta2, add_AT_vms_delta): Declare
	new static functions.
	(dwarf_attr_name): New cases DW_AT_HP_{prologue,epilogue}.
	(AT_vms_delta1, AT_vms_delta2, add_AT_vms_delta): New 
	static functions.
	(print_die): New case dw_val_class_vms_delta.
	(attr_checksum): Likewise.
	(same_dw_val_p: Likewise.
	(size_of_die): Likewise.
	(value_format): Likewise.
	(output_die): Likewise.
	(gen_subprogram_die): Call add_AT_vms_delta on VMS.
