* options.h (class General_options): Add --ctors-in-init-array. * layout.cc (Layout::get_output_section): Treat SHT_INIT_ARRAY and friends as SHT_PROGBITS for merging sections. (Layout::layout): Remove special handling of .init_array and friends. Don't sort if doing relocatable link. Sort for .ctors and .dtors if ctors_in_init_array. (Layout::make_output_section): Force correct section types for .init_array and friends. Don't sort if doing relocatable link, Don't sort .ctors and .dtors if ctors_in_init_array. (Layout::section_name_mapping): Remove .ctors. and .dtorso. (Layout::output_section_name): Add relobj parameter. Change all callers. Handle .ctors. and .dtors. in code rather than table. Handle .ctors and .dtors if ctors_in_init_array. (Layout::match_file_name): New function, moved from output.cc. * layout.h (class Layout): Update declarations. * output.cc: Include "layout.h". (Input_section_sort_entry::get_priority): New function. (Input_section_sort_entry::match_file_name): Just call Layout::match_file_name. (Output_section::Input_section_sort_init_fini_compare::operator()): Handle .ctors and .dtors. Sort by explicit priority rather than by name. * configure.ac: Remove CONSTRUCTOR_PRIORITY test and conditional. * testsuite/initpri2.c: New test. * testsuite/Makefile.am: Don't test CONSTRUCTOR_PRIORITY. (check_PROGRAMS): Add initpri2. (initpri2_SOURCES, initpri2_DEPENDENCIES): New variables. (initpri2_LDFLAGS, initpri2_LDADD): New variables. * configure, testsuite/Makefile.in: Rebuild.
