2015-04-23Delay setting up compressed debug section namesH.J. Lu3-63/+151
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.

2015-04-23Don't change compressed input debug section namesH.J. Lu5-56/+126
Change compressed input debug section name for objdump is very confusing. But we need to change it for linker so that linker will consider the input section as a debug section.

commit 9ad5cbcfb23cb74d34bd04f88f4e47c0f5de5155 added the initial support for more than 64k ELF sections with holes for reserved section indices in section header table and set entries of reserved section indices in section header table to index 0: for (secn = 1; secn < section_number; ++secn) - i_shdrp[secn]->sh_name = _bfd_elf_strtab_offset (elf_shstrtab (abfd), - i_shdrp[secn]->sh_name); - + if (i_shdrp[secn] == NULL) + i_shdrp[secn] = i_shdrp[0]; + else + i_shdrp[secn]->sh_name = _bfd_elf_strtab_offset (elf_shstrtab (abfd), + i_shdrp[secn]->sh_name); commit 4fbb74a6055f7d48f09c44064073d3b1e99c6642 removed holes in section header table.
