2015-04-23Delay setting up compressed debug section namesH.J. Lu1-10/+5
When we set up st_name for output section name in elf_fake_sections, we don't know if the compressed DWARF debug section will be smaller. We may end up with compressed DWARF debug sections which are bigger than the uncompressed ones. This patch delays setting up st_name for output DWARF debug section to _bfd_elf_assign_file_positions_for_non_load which will compress the output debug section. We also postpone placement of shstrtab section after DWARF debug sections have been compressed. The net effect is .shstrtab section is now placed after .symtab and .strtab sections. bfd/ PR ld/18277 * compress.c (bfd_compress_section_contents): Remove the write_compress argument.

2015-04-14Add --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi]H.J. Lu1-4/+47
This patch adds --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] to ld for ELF targets to support generating compressed DWARF debug sections.

2015-04-10Use bfd_alloc for compressed section contentsH.J. Lu1-3/+6
Compressed section contents should be bfd_alloced to avoid memory leak. This patch replaces bfd_malloc and free with bfd_alloc and bfd_release on compressed buffer in bfd_compress_section_contents.

This patch adds --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi} options to gas and objcopy for ELF files. They control how DWARF debug sections are compressed. --compress-debug-sections=none is equivalent to --nocompress-debug-sections. --compress-debug-sections=zlib and --compress-debug-sections=zlib-gnu are equivalent to --compress-debug-sections. --compress-debug-sections=zlib-gabi compresses DWARF debug sections with SHF_COMPRESSED from the ELF ABI.
