Make default compression gABI compliant
All programs in binutils+gdb git repo now support gABI compression
with the SHF_COMPRESSED bit. This patch makes the zlib-gabi option
as compression default for gas, gold, ld and objcopy, instead of the
zlib-gnu option whose outputs are incompatible with gABI.
binutils/
* objcopy.c (copy_file): Set BFD_COMPRESS_GABI if not
zlib-gnu.
* doc/binutils.texi: Change --compress-debug-sections and
--compress-debug-sections=zlib to zlib-gabi.
binutils/testsuite/
* binutils-all/compress.exp: Update.
gas/
* as.c (parse_args): Make --compress-debug-sections and
--compress-debug-sections=zlib the same as
--compress-debug-sections=zlib-gabi.
* doc/as.texinfo: Change --compress-debug-sections and
--compress-debug-sections=zlib to zlib-gabi.
gold/
* compressed_output.cc (Output_compressed_section::set_final_data_size):
Make --compress-debug-sections=zlib the same as
--compress-debug-sections=zlib-gabi.
* testsuite/Makefile.am (flagstest_compress_debug_sections.check):
Expect ".debug_.*" with the SHF_COMPRESSED bit, instead of
".zdebug_".
* testsuite/Makefile.in: Regenerated.
ld/
* emultempl/elf32.em (gld${EMULATION_NAME}_handle_option): Make
--compress-debug-sections=zlib the same as
--compress-debug-sections=zlib-gabi.
* ld.texinfo: Change --compress-debug-sections=zlib to zlib-gabi.
ld/testsuite/
* ld-elf/zlibbegin.rS: Updated to .debug_.* with the
SHF_COMPRESSED bit.
* ld-elf/zlibnormal.rS: Likewise.
