2017-07-28gold: Add put_ch_reserved to 64-bit Chdr_writeH.J. Lu1-0/+4
The 64-bit ELF compression header has a reserved field. It should be cleared to avoid random bits in it. elfcpp/ PR gold/21857 * elfcpp.h (Chdr_write): Add put_ch_reserved. (Chdr_write<64, true>::put_ch_reserved): New. (Chdr_write<64, false>::put_ch_reserved): Likewise. gold/ PR gold/21857 * compressed_output.cc (Output_compressed_section::set_final_data_size): Call put_ch_reserved to clear the reserved field for 64-bit ELF.

2015-07-14Make default compression gABI compliantH.J. Lu1-4/+3
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.
