2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
2023-12-28ld: Mention support for Intel APX relocations in NEWSH.J. Lu1-0/+2
2023-12-28RISC-V: PR31179, The SET/ADD/SUB fix breaks ABI compatibility with 2.41 objectsNelson Chu1-0/+5
* Problematic fix commit, 2029e13917d53d2289d3ebb390c4f40bd2112d21 RISC-V: Clarify the behaviors of SET/ADD/SUB relocations * Bugzilla, https://sourceware.org/bugzilla/show_bug.cgi?id=31179#c5 The addend of SUB_ULEB128 should be zero if using .uleb128, but we make it non-zero by accident in assembler before. This causes troubles by applying the above commit, since the calculation is changed to support .reloc *SUB* relocations with non-zero addend. We encourage people to rebuild their stuff to get the non-zero addend of SUB_ULEB128, but that might need some times, so report warnings to inform people need to rebuild their stuff if --check-uleb128 is enabled. Since the failed .reloc cases for ADD/SET/SUB/ULEB128 are rarely to use, it may acceptable that stop supproting them until people rebuld their stuff, maybe half-year or a year later. Or maybe we should teach people that don't write the .reloc R_RISCV_SUB* with non-zero constant, and then report warnings/errors in assembler. bfd/ * elfnn-riscv.c (perform_relocation): Ignore the non-zero addend of R_RISCV_SUB_ULEB128. (riscv_elf_relocate_section): Report warnings to inform people need to rebuild their stuff if --check-uleb128 is enabled. So that can get the right non-zero addend of R_RISCV_SUB_ULEB128. * elfxx-riscv.h (struct riscv_elf_params): Added bool check_uleb128. ld/ * NEWS: Updated. * emultempl/riscvelf.em: Added linker risc-v target options, --[no-]check-uleb128, to enable/disable checking if the addend of uleb128 is non-zero or not. So that people will know they need to rebuild the objects with binutils 2.42 and up, to get the right zero addend of SUB_ULEB128 relocation, or they may get troubles if using .reloc. * ld/testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated. * ld/testsuite/ld-riscv-elf/pr31179*: New test cases.

PR29397 PR29563: Add new configure option --with-zstd which defaults to auto.

The bfd change references zstd symbols, so gdb has to link against -lzstd in this patch. If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this is too heavyweight, so don't do it for now. ``` % ld/ld-new a.o ld/ld-new: a.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... % ld/ld-new a.o --compress-debug-sections=zstd ld/ld-new: --compress-debug-sections=zstd: ld is not built with zstd support % binutils/objcopy --compress-debug-sections=zstd a.o b.o binutils/objcopy: --compress-debug-sections=zstd: binutils is not built with zstd support % binutils/objcopy b.o --decompress-debug-sections binutils/objcopy: zstd.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... ```

The configure option --enable-jansson has to be used to explicitly enable it (error out when not found).
