	New functions.
	* dwarf2expr.h (dwarf_block_to_fb_offset, dwarf_block_to_sp_offset):
	New declarations.
	* dwarf2loc.c (dwarf2_find_location_expression): Support location list
	entry record.
	(dwarf_entry_parameter_to_value, value_of_dwarf_reg_entry)
	(value_of_dwarf_block_entry, locexpr_read_variable_at_entry): New
	functions.
	(dwarf2_locexpr_funcs): Install locexpr_read_variable_at_entry.
	(loclist_read_variable_at_entry): New function.
	(dwarf2_loclist_funcs): Install loclist_read_variable_at_entry.
	* dwarf2read.c (read_call_site_scope): Support also DW_OP_fbreg in
	DW_AT_location, call dwarf_block_to_sp_offset for it.
	* frame.h (print_entry_values_no, print_entry_values_only)
	(print_entry_values_preferred, print_entry_values_if_needed)
	(print_entry_values_both, print_entry_values_compact)
	(print_entry_values_default, print_entry_values): New declarations.

	arg->entry_kind.  Optionally print the `@entry' suffix.
	(list_args_or_locals): New variable entryarg, initialize it.
	Initialize also entry_kind of arg and entryarg.  Conditionalize
	list_arg_or_local for arg, add list_arg_or_local for entryarg.  Call
	xfree for entryarg.error.
	* stack.c (print_entry_values_no, print_entry_values_only)

	(print_entry_values_default, print_entry_values_choices)
	(print_entry_values): New variables.
	(print_frame_arg): New gdb_assert for arg->entry_kind.  Optionally
	print the `@entry' suffix, possibly in combination for
	print_entry_values_compact.
	(read_frame_arg): New parameter entryargp, new variables entryval,
	entryval_error and val_equal.  Read in also entryargp, respect
	print_entry_values, compare the values using val_equal, fill in also
	argp->entry_kind (together with entryargp->entry_kind).
	(print_frame_args): New variable entryarg, initialize it.
	Conditionalize print_frame_arg for arg, add print_frame_arg for
	entryarg.  Call xfree for entryarg.error.
	(_initialize_stack): Call add_setshow_enum_cmd for `entry-values'.
	* symtab.h (struct symbol_computed_ops): New field
	read_variable_at_entry.
