Add SHF_COMPRESSED section decompression to gold
This patch adds SHF_COMPRESSED section decompression to gold.
PR gold/18321
* compressed_output.h (decompress_input_section): Add arguments
for ELF class, big endian and sh_flags.
* compressed_output.cc (decompress_input_section): Likewise.
Support the SHF_COMPRESSED section.
* dynobj.h (Dynobj): Add elfsize and is_big_endian member
functions.
* plugin.h (Pluginobj): Likewise.
* layout.cc (Layout::get_output_section_flags): Also clear the
SHF_COMPRESSED bit.
* object.h (Compressed_section_info): Add flag to store sh_flags.
(Object): Add pure virtual elfsize and is_big_endian member
functions.
* object.cc (need_decompressed_section): Don't skip the ".zdebug"
prefix here.
(build_compressed_section_map): Check SHF_COMPRESSED for
uncompressed size. Store sh_flags in Compressed_section_info.
Pass size, big_endian and sh_flags to decompress_input_section.
Skip the ".debug"/".zdebug" prefix when passing section name to
need_decompressed_section.
(Sized_relobj_file<size, big_endian>::do_find_special_section):
Don't check ".zdebug_*" sections.
(Object::decompressed_section_contents): Pass ELF class, big
endian and sh_flags to decompress_input_section.
* reloc.cc (Sized_relobj_file<size, big_endian>::write_sections):
Likewise.
* testsuite/Makefile.am (check_DATA): Add
debug_msg_cdebug_gabi.err and gdb_index_test_2_gabi.stdout.
(MOSTLYCLEANFILES): Add debug_msg_cdebug_gabi.err and
gdb_index_test_2_gabi.stdout.
(debug_msg_cdebug_gabi.o): New.
(odr_violation1_cdebug_gabi.o): Likewise.
(odr_violation2_cdebug_gabi.o): Likewise.
(debug_msg_cdebug_gabi.err): Likewise.
(check_SCRIPTS): Add gdb_index_test_2_gabi.sh.
(gdb_index_test_cdebug_gabi.o): Likewise.
(gdb_index_test_2_gabi): Likewise.
(gdb_index_test_2_gabi.stdout): Likewise.
* testsuite/gdb_index_test_2_gabi.sh: New file.
* testsuite/Makefile.in: Regenerated.
