2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

2022-09-30LoongArch: Update ELF e_flags handling according to specification.liuzhensong1-3/+18
Update handling of e_flags according to the documentation update [1] (discussions [2][3]). Object file bitness is now represented in the EI_CLASS byte. The e_flags field is now interpreted as follows: e_flags[2:0]: Base ABI modifier - 0x1: soft-float - 0x2: single-precision hard-float - 0x3: double-precision hard-float e_flags[7:6]: ELF object ABI version - 0x0: v0 - 0x1: v1 [1]: https://github.com/loongson/LoongArch-Documentation/blob/main/docs/LoongArch-ELF-ABI-EN.adoc#e_flags-identifies-abi-type-and-version [2]: https://github.com/loongson/LoongArch-Documentation/pull/61 [3]: https://github.com/loongson/LoongArch-Documentation/pull/47
2022-09-20LoongArch: Fix R_LARCH_IRELATIVE insertion after elf_link_sort_relocsXi Ruoyao1-17/+24
loongarch_elf_finish_dynamic_symbol is called after elf_link_sort_relocs if -z combreloc. elf_link_sort_relocs redistributes the contents of .rela.* sections those would be merged into .rela.dyn, so the slot for R_LARCH_IRELATIVE may be out of relplt->contents now. To make things worse, the boundary check dyn < dyn + relplt->size / sizeof (*dyn) is obviously wrong ("x + 10 < x"? :), causing the issue undetected during the linking process and the resulted executable suddenly crashes at runtime. The issue was found during an attempt to add static-pie support to the toolchain. Fix it by iterating through the inputs of .rela.dyn to find the slot.
2022-09-20LoongArch: Don't write into GOT for local ifuncXi Ruoyao1-2/+3
Local ifuncs are always resolved at runtime via R_LARCH_IRELATIVE, so there is no need to write anything into GOT. And when we write the GOT we actually trigger a heap-buffer-overflow: If a and b are different sections, we cannot access something in b with "a->contents + (offset from a)" because "a->contents" and "b->contents" are heap buffers allocated separately, not slices of a large buffer. So stop writing into GOT for local ifunc now.

2022-07-25bfd: Delete R_LARCH_NONE from dyn info of LoongArch.liuzhensong1-0/+11
Some R_LARCH_64 in section .eh_frame will to generate R_LARCH_NONE, we change relocation to R_LARCH_32_PCREL from R_LARCH_64 in setction .eh_frame and not generate dynamic relocation for R_LARCH_32_PCREL. Add New relocate type R_LARCH_32_PCREL for .eh_frame. include/elf/ loongarch.h bfd/ bfd/bfd-in2.h libbfd.h reloc.c elfxx-loongarch.c elfnn-loongarch.c gas/config/ tc-loongarch.c binutils/ readelf.c ld/testsuite/ld-elf/ eh5.d

Delete R_LARCH_IRELATIVE from dynamic loader (glibc ld.so) when loading lazy function (rela.plt section). In dynamic programes, move ifunc dynamic relocate info to section srelgot from srelplt. bfd/ elfnn-loongarch.c

2022-05-05loongarch: Don't check ABI flags if no code sectionXi Ruoyao1-0/+21
Various packages (glib and gtk4 for example) produces data-only objects using `ld -r -b binary` or `objcopy`, with no elf header flags set. But these files also have no code sections, so they should be compatible with all ABIs. bfd/ * elfnn-loongarch.c (elfNN_loongarch_merge_private_bfd_data): Skip ABI checks if the input has no code sections.

Replace the magic numbers in gas(tc-loongarch.c) and bfd(elfnn-loongarch.c) with the functions defined in the howto table(elfxx-loongarch.c). gas/ * config/tc-loongarch.c: use functions. bfd/ * elfnn-loongarch.c: use functions. * elfxx-loongarch.c: define functions. * elfxx-loongarch.h
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
