2024-06-20Revert "Remove LIBINTL_DEP"Alan Modra2-2/+5
This reverts commit e874cbd3879843a83e4bcc4b54cd7107387b1df6. The patch was wrong. LIBINTL_DEP is needed with an in-tree gettext.

2024-06-20LoongArch: TLS IE needs only one dynamic relocXi Ruoyao1-1/+1
As the comment in the code says, TLS_IE needs only one dynamic reloc. But commit b67a17aa7c0c ("LoongArch: Fix the issue of excessive relocation generated by GD and IE") has incorrectly allocated the space for two dynamic relocs, causing libc.so to contain 8 R_LARCH_NONE. Adjust tlsdesc-dso.d for the offset changes and add two tests to ensure there are no R_LARCH_NONE with TLS. Signed-off-by: Xi Ruoyao <xry111@xry111.site>

2024-06-17Error messages emitted during bfd_check_format_matchesAlan Modra1-7/+27
Error/warning messages are only printed for the target that successfully matched, which makes sense for warnings, but not so much for errors where the errors cause no target to match. I noticed this when looking at the pr20520 testcase again with objdump, which just reports "file format not recognized" omitting the five "SHT_GROUP section [index n] has no SHF_GROUP sections" messages. They are omitted because multiple ELF targets match the object file. This is going to be true for all ELF objects due to at least the proper ELF target and the generic ELF target matching. * format.c (print_and_clear_messages): Print messages if all targets with messages have exactly the same set of messages.

2024-06-07aarch64: Fix DT_RELR support with discarded sectionsSzabolcs Nagy1-2/+3
In case of discarded sections, via /DISCARD/ or .gnu.linkonce, relr relocation accounting was wrong. This broke building linux. The issue was that the *_relocate_section logic was copied to record_relr_non_got_relocs to find the relative relocs that can be packed, however *_relocate_section is not called on sections that are discarded, while record_relr_non_got_relocs is called for all input sections. The fix is to filter out the discarded sections with the same logic that is used to count non-GOT relocs in *_late_size_sections for local symbols earlier. Use the discarded_section helper in both cases to clarify the intent and handle all corner-cases consistently. GOT relocations are affected too if all sections are discarded that reference the GOT entry of a particular symbol, however this can cause unused GOT entries independently of DT_RELR, and the only difference with DT_RELR is that a relative reloc may be emitted instead of a R_AARCH64_NONE for the unused GOT entry which is acceptable. A proper fix would require redoing the GOT refcounting after we know the discarded sections, see bug 31850.

2024-06-04LoongArch: Make align symbol be in same section with alignment directivemengqinggang4-29/+1
R_LARCH_ALIGN (psABI v2.30) requires a symbol index. The symbol is only created at the first time to handle alignment directive. This means that all other sections may use this symbol. If the section of this symbol is discarded, there may be problems. Search it in its own section. Remove elf_backend_data.is_rela_normal() function added at commit daeda14191c.

2024-05-31aarch64: Add DT_RELR supportSzabolcs Nagy2-1/+439
The logic to decide if an input relocation for a symbol becomes a particular kind of output relocation is one of the hard to maintain parts of the bfd ld backend, since it is partially repeated across elfNN_aarch64_check_relocs (where dynamic relocations are counted per symbol and input section), elfNN_aarch64_late_size_sections (where relocation sections are sized and GOT offsets assigned), elfNN_aarch64_relocate_section (where most relocations are applied and output to a relocation section), elfNN_aarch64_finish_dynamic_symbol (where some of the GOT relocations are applied and output). The DT_RELR support adds another layer to this complexity: after the output relocation sections are sized, so all dynamic relocations are accounted (in elfNN_aarch64_late_size_sections), we scan the symbols and input relocations again to decide which ones become relative relocations that can be packed. The sizes of the relocation sections are updated accordingly. This logic must be consistent with the code that applies the relocs later so each relative relocation is emitted exactly once: either in .rela.* or packed in .relr.dyn. Sizing of .relr.dyn is done via elfNN_aarch64_size_relative_relocs that may be called repeatedly whenever the layout changes since an address change can affect the size of the packed format. Then the final content is emitted in elfNN_aarch64_finish_relative_relocs, that is called after the layout is final and before relocations are applied and emitted. These hooks are only called if DT_RELR is enabled. We only pack relative relocs that are known to be aligned in the output during .relr.dyn sizing, the potentially unaligned relative relocs are emitted normally (in .rela.*, not packed), because the format requires aligned addresses.
