2020-02-26PR25593, --as-needed breaks DT_NEEDED order with linker pluginAlan Modra3-1/+29
This patch delays setting up DT_NEEDED dynamic tags until all object files and libraries have been opened and their symbols processed, rather than adding the tags while processing symbols. Tags are ordered according to the position of the associated library on the command line and linker scripts. It is still possible with --as-needed libs that are mentioned more than once for tags to be ordered according to which mention was needed. For example with "--as-needed a.so b.so c.so b.so" when b.so is not needed by a.so or any other prior object file but is needed by c.so, the order of tags will be "A C B". bfd/ PR 25593 * elf-bfd.h (struct elf_link_hash_table): Rename "loaded" to "dyn_loaded". (bfd_elf_add_dt_needed_tag): Declare. * elf-strtab.c (_bfd_elf_strtab_restore): Handle NULL buf. * elflink.c (bfd_elf_add_dt_needed_tag): Make global and rename from elf_add_dt_needed_tag.

Mark libs loaded via DT_NEEDED entries of other libs with DYN_NO_NEEDED if they should not be mentioned in DT_NEEDED of the output.

2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu4-7/+14
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.
