Options

tree.h (BLOCK_IN_COLD_SECTION_P): Define. 

	* tree.h (BLOCK_IN_COLD_SECTION_P): Define.
	* final.c (final_scan_insn): Set BLOCK_IN_COLD_SECTION_P.
	* dwarf2out.c (rnglist_idx): New variable.
	(struct dw_ranges): Add label, idx and maybe_new_sec fields.
	(DEBUG_RNGLISTS_SECTION): Define.
	(ranges_base_label): New variable.
	(size_of_die) <case dw_val_class_range_list>: If using
	DW_FORM_rnglistx, count size of uleb128 of range list index.
	(value_format) <case dw_val_class_range_list>: For
	-gdwarf-5 -gsplit-dwarf return DW_FORM_rnglistx.
	(output_range_list_offset): Handle -gdwarf-5 .debug_rnglists
	offsets.  Multiply dwarf < 5 offsets by 2 * DWARF_ADDR_SIZE.
	(add_ranges_num): Remove useless prototype.  Don't multiply
	by 2 * DWARF2_ADDR_SIZE.  Add maybe_new_sec argument, adjust
	for new fields added to dw_ranges struct.
	(add_ranges): Add maybe_new_sec argument and pass it
	through to add_ranges_num.
	(note_rnglist_head): New function.
	(add_ranges_by_labels): Pass true as maybe_new_sec to
	add_ranges_num, call note_rnglist_head on the head of the list.
	(output_ranges): Add function comment.  Switch to
	.debug_ranges section here and emit .Ldebug_ranges0 label.
	(index_rnglists, output_rnglists): New functions.
	(gen_subprogram_die): Formatting fixes.
	(add_high_low_attributes): Don't divide offsets
	by 2 * DWARF2_ADDR_SIZE.  Call note_rnglist_head on the
	first list element or when pointing into the middle of
	a list.  Pass true as second argument to add_ranges on the
	first block fragment after cold/hot section switch.
	(init_sections_and_labels): For -gdwarf-5 use .debug_rnglists
	section instead of .debug_ranges.  Initialize
	ranges_base_label if -gdwarf-5 -gsplit-dwarf.
	(dwarf2out_finish): For -gdwarf-5 -gsplit-dwarf call
	index_rnglists and add DW_AT_rnglists_base attr.  Don't switch
	to dwarf_ranges_section here or emit .Ldebug_ranges0 label.
	Call output_rnglists for -gdwarf-5.
	(dwarf2out_c_finalize): Clear rnglist_idx.
