* Compression header enumAlan Modra2022-12-061-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Define an enum instead of using ELFCOMPRESS_ZLIB and ELFCOMPRESS_ZSTD in bfd and binutils, and move some functions from bfd.c to compress.c. When looking at the COFF/PE debug compression support, I wondered about extending it to support zstd. I likely won't do that, but the compression header ch_type field isn't just ELF specific if these headers are to be used in COFF/PE too. bfd/ * bfd.c (bfd_update_compression_header), (bfd_check_compression_header, bfd_get_compression_header_size), (bfd_convert_section_size, bfd_convert_section_contents): Move to.. * compress.c: ..here.

* Don't use "long" in readelf for file offsetsAlan Modra2022-11-231-472/+505
| | | | | | | | | | | | | | | | | | | | | | | The aim here is to improve readelf handling of large 64-bit object files on LLP64 hosts (Windows) where long is only 32 bits. The patch changes more than just file offsets. Addresses and sizes are also changed to avoid "long". Most places get to use uint64_t even where size_t may be more appropriate, because that allows some overflow checks to be implemented easily (*alloc changes). * dwarf.c (cmalloc, xcmalloc, xcrealloc, xcalloc2): Make nmemb parameter uint64_t. * dwarf.h: Update prototypes. (struct dwarf_section): Make num_relocs uint64_t. * elfcomm.c (setup_archive): Update error format. * elfcomm.h (struct archive_info): Make sym_size, longnames_size, nested_member_origin, next_arhdr_offset uint64_t. * readelf.c (struct filedata): Make archive_file_offset, archive_file_size, string_table_length, dynamic_addr, dynamic_nent, dynamic_strings_length, num_dynamic_syms, dynamic_syminfo_offset uint64_t. (many functions): Replace uses of "unsigned long" with "uint64_t" or "size_t".
* Re: readelf: use fseeko64 or fseeko if possibleAlan Modra2022-11-231-51/+74

* readelf: use fseeko64 or fseeko if possibleBrett Werling2022-11-221-11/+19
| | | | | | | | | | | | | | | Changes readelf to make use first of fseeko64 and then fseeko, depending on which of those is available. If neither is available, reverts to the previous behavior of using fseek. This is necessary when building readelf for LLP64 systems, where a long will only be 32 bits wide. If the elf file in question is >= 2 GiB, that is greater than the max long value and therefore fseek will fail indicating that the offset is negative. On such systems, making use of fseeko64 or fseeko will result in the ability so seek past the 2 GiB max long boundary. Note that large archive handling in readelf remains to be fixed.
* readelf/objdump: support for SFrame sectionIndu Bhagat2022-11-151-0/+63
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for SFrame in readelf and objdump. The arguments of --sframe are optional for both readelf and objdump. include/ChangeLog: * sframe-api.h (dump_sframe): New function declaration.

* bfd: linker: merge .sframe sectionsIndu Bhagat2022-11-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The linker merges all the input .sframe sections. When merging, the linker verifies that all the input .sframe sections have the same abi/arch. The linker uses libsframe library to perform key actions on the .sframe sections - decode, read, and create output data. This implies buildsystem changes to make and install libsframe before libbfd. The linker places the output .sframe section in a new segment of its own: PT_GNU_SFRAME. A new segment is not added, however, if the generated .sframe section is empty. When a section is discarded from the final link, the corresponding entries in the .sframe section for those functions are also deleted. The linker sorts the SFrame FDEs on start address by default and sets the SFRAME_F_FDE_SORTED flag in the .sframe section. This patch also adds support for generation of SFrame unwind information for the .plt* sections on x86_64. SFrame unwind info is generated for IBT enabled PLT, lazy/non-lazy PLT. The existing linker option --no-ld-generated-unwind-info has been adapted to include the control of whether .sframe unwind information will be generated for the linker generated sections like PLT. Changes to the linker script have been made as necessary.

* Make dwarf_vma uint64_tAlan Modra2022-08-131-20/+20
| | | | | | | | | | | | | | This replaces dwarf_vma, dwarf_size_type and dwarf_signed_vma with uint64_t and int64_t everywhere. The patch also gets rid of DWARF_VMA_FMT since we can't use that with uint64_t, and all of the configure support for deciding the flavour of HOST_WIDEST_INT. dwarf_vmatoa also disappears, replacing most uses with one of PRIx64, PRId64 or PRIu64. Printing of size_t and ptrdiff_t values now use %z and %t rather than by casting to unsigned long. Also, most warning messages that used 0x%lx or similar now use %#lx and a few that didn't print the 0x hex prefix now also use %#. The patch doesn't change normal readelf output, except in odd cases where values previously might have been truncated.
* Don't use bfd_vma in readelf.cAlan Modra2022-08-131-221/+172
| | | | | | This replaces bfd_vma with uint64_t in readelf, defines BFD64 unconditionally, removes tests of BFD64 and sizeof (bfd_vma), and removes quite a few now unnecessary casts.
* Don't use bfd_size_type in readelf.c and dwarf.cAlan Modra2022-08-131-68/+61
| | | | | | | Replacing bfd_size_type with dwarf_size_type or uint64_t is mostly cosmetic. The point of the change is to avoid use of a BFD type in readelf, where we'd like to keep as independent of BFD as possible. Also, the patch is a step towards using standard types.
* Replace elf_vma with uint64_tAlan Modra2022-08-131-2/+2
| | | | | | This patch replaces all uses of elf_vma with uint64_t, removes tests of sizeof (elf_vma), and does a little tidying of byte_get_little_endian and byte_get_big_endian.
* Recognize the new ELF compression type for ZSTD.Cary Coutant2022-08-041-0/+2
| | | | | | | | | | There is more work to be done to actually support compression and decompression using the zstd library, but I will leave that to the champions of the new compression option. binutils/ * binutils/readelf.c (process_section_headers): Add support for ELFCOMPRESS_ZSTD.
* Don't use BFD_VMA_FMT in binutilsAlan Modra2022-08-041-76/+57
| | | | | | | | | | | | | BFD_VMA_FMT can't be used in format strings that need to be translated, because the translation won't work when the type of bfd_vma differs from the machine used to compile .pot files. We've known about this for a long time, but patches slip through review. So just get rid of BFD_VMA_FMT, instead using the appropriate PRId64, PRIu64, PRIx64 or PRIo64 and SCN variants for scanf. The patch is mostly mechanical, the only thing requiring any thought is casts needed to preserve PRId64 output from bfd_vma values, or to preserve one of the unsigned output formats from bfd_signed_vma values.
* Get rid of fprintf_vma and sprintf_vmaAlan Modra2022-08-011-26/+15

Unfortunately they depend on both target and host, which means that the output for 32-bit targets may be either 8 or 16 hex digits. Replace them in most cases with code that prints a bfd_vma using PRIx64. In some cases, deliberately lose the leading zeros. This change some output, notably in base/offset fields of m68k disassembly which I think looks better that way, and in error messages. I've kept leading zeros in symbol dumps (objdump -t) and in PE header dumps. bfd/ * bfd-in.h (fprintf_vma, sprintf_vma, printf_vma): Delete. * bfd-in2.h: Regenerate. * bfd.c (bfd_sprintf_vma): Don't use sprintf_vma.

* [AArch64] Support AArch64 MTE memory tag dumps in core filesLuis Machado2022-07-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | The Linux kernel can dump memory tag segments to a core file, one segment per mapped range. The format and documentation can be found in the Linux kernel tree [1]. The following patch adjusts bfd and binutils so they can handle this new segment type and display it accordingly. It also adds code required so GDB can properly read/dump core file data containing memory tags. Upon reading, each segment that contains memory tags gets mapped to a section named "memtag". These sections will be used by GDB to lookup the tag data. There can be multiple such sections with the same name, and they are not numbered to simplify GDB's handling and lookup. There is another patch for GDB that enables both reading and dumping of memory tag segments. Tested on aarch64-linux Ubuntu 20.04.

* binutils/readelf: build against msgpack, dump NT_AMDGPU_METADATA note contentsSimon Marchi2022-03-161-14/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AMDGPU HSA OS ABI (code object v3 and above) defines the NT_AMDGPU_METADATA ELF note [1]. The content is a msgpack object describing, among other things, the kernels present in the code object and how to call them. I think it would be useful for readelf to be able to display the content of those notes. msgpack is a structured format, a bit like JSON, except not text-based. It is therefore possible to dump the contents in human-readable form without knowledge of the specific layout of the note. Add configury to binutils to optionally check for the msgpack C library [2]. Add There is a new --with{,out}-msgpack configure flag, and the actual library lookup is done using pkg-config. If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks like: $ readelf --notes amdgpu-code-object Displaying notes found in: .note Owner Data size Description AMDGPU 0x0000040d NT_AMDGPU_METADATA (code object metadata) { "amdhsa.kernels": [ { ".args": [ { ".address_space": "global", ".name": "out.coerce", ".offset": 0, ".size": 8, ".value_kind": "global_buffer", }, <snip> If msgpack support is disabled, dump the contents as hex, as is done with notes that are not handled in a special way. This allows one to decode the contents manually (maybe using a command-line msgpack decoder) if really needed.

But the NONE, PAL and MESA3D OS ABIs are not well documented nor versioned. Taking a peek at the LLVM source code, we see that they encode their flags the same way as HSA v3. For example, for PAL: https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601 So for those other OS ABIs, we read them the same as HSA v3. binutils/ChangeLog: * readelf.c: Include elf/amdgcn.h.

* RISC-V: Support STO_RISCV_VARIANT_CC and DT_RISCV_VARIANT_CC.Nelson Chu2021-11-191-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the original discussion, https://github.com/riscv/riscv-elf-psabi-doc/pull/190 And here is the glibc part, https://sourceware.org/pipermail/libc-alpha/2021-August/129931.html For binutils part, we need to support a new direcitve: .variant_cc. The function symbol marked by .variant_cc means it need to be resolved directly without resolver for dynamic linker. We also add a new dynamic entry, STO_RISCV_VARIANT_CC, to indicate there are symbols with the special attribute in the dynamic symbol table of the object. I heard that llvm already have supported this in their mainline, so I think it's time to commit this. bfd/ * elfnn-riscv.c (riscv_elf_link_hash_table): Added variant_cc flag. It is used to check if relocations for variant CC symbols may be present. (allocate_dynrelocs): If the symbol has STO_RISCV_VARIANT_CC flag, then raise the variant_cc flag of riscv_elf_link_hash_table. (riscv_elf_size_dynamic_sections): Added dynamic entry for variant_cc. (riscv_elf_merge_symbol_attribute): New function, used to merge non-visibility st_other attributes, including STO_RISCV_VARIANT_CC. binutils/ * readelf.c (get_riscv_dynamic_type): New function.
