(m32r_skip_prologue): Extend search limit. Quit analyzing
prologue if pc's location is not readable.

functions that are done for .y.c files, plus special one
for yy_flex_realloc. Also, correct missing-file tests here.

functions.
* ada-exp.y (dummy_string_to_ada_operator): Temporary definition
to suppress warning.
RETURN_VALUE.
(sh_return_value_fpu): Ditto for CPUs with FPU.
(sh_gdbarch_init): Remove STORE_RETURN_VALUE, EXTRACT_RETURN_VALUE,
RETURN_VALUE_ON_STACK and USE_STRUCT_CONVENTION throughout.
Install sh_return_value_nofpu resp. sh_return_value_fpu as
RETURN_VALUE functions.

(struct dwarf2_pinfo, PST_PRIVATE, DWARF_INFO_OFFSET): Remove.
(struct dwarf2_queue_item, dwarf2_queue, dwarf2_queue_tail): New.
(dwarf2_create_include_psymtab): Update comment.
(find_partial_die): Remove third argument. Remove unreachable call
to error ().
(dwarf2_find_containing_comp_unit): Update comments. Change one
assertion to an error. Remove an unreachable error.
(dwarf2_find_comp_unit): Update comments.
(type_at_offset): Remove dead code.
(make_cleanup_free_die_list, dwarf2_empty_hash_tables): Remove.
(store_in_ref_table): Add CU argument.
(follow_die_ref): Take DIE, attribute, and CU arguments. Handle
inter-compilation-unit references.
(load_full_comp_unit, process_full_comp_unit): New functions, based
on psymtab_to_symtab_1.
(psymtab_to_symtab_1): Use them.
(dwarf2_add_dependence): New function.
(dwarf2_build_psymtabs_hard): Set the psymtab in per_cu. Always create
a per_cu structure, and save it in READ_PSYMTAB_PRIVATE.
(partial_die_parent_scope, guess_structure_name): Update for changes
to find_partial_die.
(dwarf2_psymtab_to_symtab): Initialize dwarf2_per_objfile here.
(queue_comp_unit, process_queue, dwarf2_release_queue): New.
(read_comp_unit): Don't call dwarf2_empty_hash_tables.
(read_die_and_children): Update call to store_in_ref_table.
(do_free_die_list_cleanup): Remove.
(fixup_partial_die): Update for changes to find_partial_die.
(read_full_die): Handle queueing absolute references.
(read_attribute_value): Use DW_ADDR for all DW_FORM_ref* forms.
(dwarf2_attr, die_specification, die_type)
(die_containing_type, dwarf2_extension): Update calls to
follow_die_ref.
(dump_die): Update DW_FORM_ref* handling.
(dwarf2_get_ref_die_offset): Likewise.
(free_one_comp_unit): Release the dies list.
(dwarf2_mark_helper): New function.
(dwarf2_mark): Use it.
* scripttempl/elf.sc (DATA_SEGMENT_RELRO_END): Add 0 as first
argument.
(DATA_SEGMENT_RELRO_GOTPLT_END): Pass $SEPARATE_GOTPLT as first
and . as second argument.
(GOTPLT): Move $DATA_SEGMENT_RELRO_GOTPLT_END before the section.
* ldexp.c (fold_unary): Remove DATA_SEGMENT_RELRO_END handling here.
(fold_binary): Add it here. Insert padding to make relro_end
COMMONPAGESIZE bytes aligned. For DATA_SEGMENT_ALIGN in
exp_dataseg_relro_adjust phase just use previously computed
exp_data_seg.base.
* ldlang.c (lang_size_sections): Set exp_data_seg.base for
relro_adjust here. Call lang_size_sections_1 once more if there
was too big padding at DATA_SEGMENT_RELRO_END.
* ld.texinfo (DATA_SEGMENT_RELRO_END): Add documentation.
