* layout.cc (Layout::layout): If we see an input section with a
name that needs sorting, set the must_sort flag for the output
section.
(Layout::make_output_section): If the name of the output section
indicates that it might require sorting, set the may_sort flag.
* output.h (Output_section::may_sort_attached_input_sections): New
function.
(Output_section::set_may_sort_attached_input_sections): New
function.
(Output_section::must_sort_attached_input_sections): New
function.
(Output_section::set_must_sort_attached_input_sections): New
function.
(class Output_section): Declare Input_section_sort_entry. Define
Input_section_sort_compare. Declare
sort_attached_input_sections. Add new fields:
may_sort_attached_input_sections_,
must_sort_attached_input_sections_,
attached_input_sections_are_sorted_.
* output.cc (Output_section::Output_section): Initialize new
fields.
(Output_section::add_input_section): Add an entry to
input_sections_ if may_sort or must_sort are true.
(Output_section::set_final_data_size): Call
sort_attached_input_sections if necessary.
(Output_section::Input_section_sort_entry): Define new class.
(Output_section::Input_section_sort_compare::operator()): New
function.
(Output_section::sort_attached_input_sections): New function.
* configure.ac: Check whether the compiler supports constructor
priorities. Define a CONSTRUCTOR_PRIORITY automake conditional.
* testsuite/initpri1.c: New file.
* testsuite/Makefile.am (check_PROGRAMS): Add initpri1 if
CONSTRUCTOR_PRIORITY.
