2024-02-19aarch64: Add new relocations and limit COFF AArch64 relocation offsetsZac Walker1-0/+31
The patch adds support for the IMAGE_REL_ARM64_REL32 coff relocation type. This is needed for 32-bit relative address. It also adds a check for relocation offsets over 21 bits. Offsets inside coff files are stored in instruction code. In the case of ADRP the actual value is stored, not a downshifted page offset. This means values over 21 bits would otherwise be truncated. Finally it adds a mapping for BFD_RELOC_AARCH64_ADR_GOT_PAGE and BFD_RELOC_AARCH64_LD64_GOT_LO12_NC that were previously skipped. ChangeLog: * bfd/coff-aarch64.c (coff_aarch64_reloc_type_lookup): Add BFD_RELOC_AARCH64_ADR_GOT_PAGE, BFD_RELOC_AARCH64_LD64_GOT_LO12_NC and IMAGE_REL_ARM64_REL32 relocations. (coff_pe_aarch64_relocate_section): Likewise. * gas/write.c (adjust_reloc_syms): COFF AArch64 relocation offsets need to be limited to 21bits (defined): Likewise.
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.
2023-08-03Remove PEI_HEADERS defineTom Tromey1-7/+0
I noticed a few files double-included libcoff.h, and digging deeper I found that the PEI_HEADERS define is a sort of external include guard. This patch adds include guards to the few files in include/coff that were missing one, and then removes the PEI_HEADERS workaround and the redundant includes. I didn't see anything in these files that indicated that double-inclusion would be useful, so it seems to me that this approach is ok. Tested by rebuilding with --enable-targets=all. 2023-08-02 Tom Tromey <tromey@adacore.com> * pei-x86_64.c (PEI_HEADERS): Do not define. * pei-loongarch64.c (PEI_HEADERS): Do not define. * pei-aarch64.c (PEI_HEADERS): Do not define. * pe-x86_64.c (PEI_HEADERS): Do not define. * pe-aarch64.c (PEI_HEADERS): Do not define. * libpei.h (_LIBPEI_H): Add include guard. * coff-x86_64.c (PEI_HEADERS): Do not check. * coff-loongarch64.c (PEI_HEADERS): Do not check. * coff-aarch64.c (PEI_HEADERS): Do not check. include/ChangeLog 2023-08-02 Tom Tromey <tromey@adacore.com> * coff/x86_64.h (COFF_X86_64_H): Add include guard. * coff/loongarch64.h (COFF_LOONGARCH64_H): Add include guard. * coff/aarch64.h (COFF_AARCH64_H): Add include guard.
2023-01-27segv in coff_aarch64_addr32nb_relocAlan Modra1-3/+4
* coff-aarch64.c (coff_aarch64_addr32nb_reloc): When output_bfd is NULL (which it is for objdump -W) get the output bfd via the input section.
2023-01-23Add support for secidx relocations to aarch64-w64-mingw32Mark Harmstone1-1/+35
This patch adds support for the .secidx directive and its corresponding relocation to aarch64-w64-mingw32. As with x86, this is a two-byte LE integer which gets filled in with the 1-based index of the output section that a symbol ends up in. This is needed for PDBs, which represent addresses as a .secrel32, .secidx pair. The test is substantially the same as for amd64, but with changes made for padding and alignment.
2023-01-19The fuzzers have found the reloc special functions in coff-aarch64.cAlan Modra1-42/+157
All of them need a bfd_reloc_offset_in_range check before accessing data + reloc_entry->address. This patch adds the missing checks and sanity checks reloc offsets in coff_pe_aarch64_relocate_section too. All of them also need changing to support objdump -W calls to bfd_simple_get_relocated_section_contents. At least, secrel_reloc needs the support, the others might not be present in dwarf debug sections. * coff-aarch64.c (coff_aarch64_rel21_reloc): Range check reloc offset. Support final-linking. (coff_aarch64_po12l_reloc): Likewise. (coff_aarch64_addr32nb_reloc): Likewise. (coff_aarch64_secrel_reloc): Likewise. (coff_pe_aarch64_relocate_section): Range check reloc offset.
2023-01-19Correct coff-aarch64 howtos and delete unnecessary special functionsAlan Modra1-157/+44
The remaining special functions are still broken except when called by gas bfd_install_relocation. * coff-aarch64.c (coff_aarch64_addr64_reloc), (coff_aarch64_addr32_reloc, coff_aarch64_branch26_reloc), (coff_aarch64_branch19_reloc, coff_aarch64_branch14_reloc), (coff_aarch64_po12a_reloc): Delete. (HOWTO_INSTALL_ADDEND): Define as 1. (HOW): Remove pcrel_off. Correct all the howtos. (CALC_ADDEND): Define. (coff_aarch64_rtype_to_howto): New function. (coff_rtype_to_howto): Define.
2023-01-19coff-aarch64.c howtosAlan Modra1-67/+56
This is just a patch to fix overlong lines. Wrapping the HOWTO macro in a new HOW macro helps in this. No functional changes here. * coff-aarch64.c (HOW): Define and use for reloc howtos.
2023-01-10Add .secrel32 for pe-aarch64Mark Harmstone1-1/+46
Adds the .secrel32 pseudo-directive and its corresponding relocation.
2023-01-10Add pe-aarch64 relocationsMark Harmstone1-14/+660
This adds the remaining pe-aarch64 relocations, and gets them working. It also brings in the constant directives from ELF, as otherwise .word would be 2 rather than 4 bytes, and .xword and .dword wouldn't be defined.
2023-01-10Fix size of external_reloc for pe-aarch64Mark Harmstone1-4/+0
This patch series finishes off the work by Jedidiah Thompson, and adds support for creating aarch64 PE images. This should be essentially complete: I've used this to create a "hello world" Windows program in asm, and (with GCC patches) a UEFI program in C. I think the only things missing are the .secidx relocation, which is needed for PDBs, and the SEH pseudos used for C++ exceptions. This first patch fixes the size of RELSZ; I'm not sure why it was 14 in the first place. This is the size of the "Base Relocation Block" in https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, and AFAIK should be 10 for everything.
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.
2022-10-19aarch64-pe support for LD, GAS and BFDJedidiah Thompson1-26/+142
Allows aarch64-pe to be targeted natively, not having to use objcopy to convert it from ELF to PE. Based on initial work by Jedidiah Thompson Co-authored-by: Jedidiah Thompson <wej22007@outlook.com> Co-authored-by: Zac Walker <zac.walker@linaro.org>
2022-08-15aarch64_pei_vecAlan Modra1-0/+4
I know this target is just a skeleton, but let's not write out relocs with uninitialised garbage. * coff-aarch64.c (SWAP_IN_RELOC_OFFSET): Define. (SWAP_OUT_RELOC_OFFSET): Define.
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.
2021-11-23AArch64: Add support for AArch64 EFI (efi-*-aarch64).Tamar Christina1-0/+166
This adds support for efi-*-aarch64 by virtue of adding a new PEI target pei-aarch64-little. This is not a full target and only exists to support EFI at this time. This means that this target does not support relocation processing and is mostly a container format. This format has been added to elf based aarch64 targets such that efi images can be made natively on Linux. However this target is not valid for use with gas but only with objcopy. With these changes the resulting file is recognized as an efi image by third party tools: > pecli info hello.efi Metadata ================================================================================ MD5: 598c32a778b0f0deebe977fef8578c4e SHA1: 4580121edd5cb4dc40f51b28f171fd15250df84c SHA256: 3154bd7cf42433d1c957f6bf55a17ad8c57ed41b29df2d485703349fd6ff1d5c Imphash: Size: 47561 bytes Type: PE32+ executable (EFI application) (stripped to external PDB), for MS Windows Compile Time: 1970-01-01 00:00:00 (UTC - 0x0 ) Entry point: 0x2000 (section .text) Sections ================================================================================ Name RWX VirtSize VirtAddr RawAddr RawSize Entropy md5 .text R-X 0x5bb0 0x2000 0x400 0x5c00 6.39 551fbc264256a3f387de8a891500ae0d .reloc R-- 0xc 0x8000 0x6000 0x200 0.02 0c45f6d812d079821c1d54c09ab89e1d .data RW- 0x1d88 0x9000 0x6200 0x1e00 4.18 5d1137c09f01289dc62bf754f7290db3 .dynamic RW- 0xf0 0xb000 0x8000 0x200 0.34 5c94ed3206f05a277e6f04fbf131f131 .rela R-- 0xe58 0xc000 0x8200 0x1000 1.87 8b5c6bc30f3acb7ca7bf2e6789d68519 .dynsym R-- 0x138 0xd000 0x9200 0x200 0.96 bdcf5101da51aadc663ca8859f88138c Imports ================================================================================ Any magic number is based on the Microsoft PE specification [1].
