This patch adds the end prologue and begin epilogue markers in Dwarf2
that are needed by the VMS debugger on I64.
* config/ia64/vms.h (ASM_OUTPUT_DWARF_DELTA_UNITS): Remove.
(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.
(dwarf2out_begin_epilogue): Rename to dwarf2out_cfi_begin_epilogue
* dwarf2out.h (dwarf2out_begin_epilogue): Rename to
dwarf2out_cfi_begin_epilogue
* final.c (final_scan_insn): Likewise. Call begin_epilogue.
