2022-01-18PR28029, debuginfod testsAlan Modra1-50/+62
binutils/NEWS says of the change in --process-links semantics: If other debug section display options are also enabled (eg --debug-dump=info) then the contents of matching sections in both the main file and the separate debuginfo file *will* be displayed. This is because in most cases the debug section will only be present in one of the files. Implying that debug info is dumped without --process-links. Indeed that appears to be the case for readelf. This does the same for objdump. PR 28029 * objdump.c (dump_bfd): Do not exit early when !is_mainfile && !processlinks, instead just exclude non-debug output. (dump_dwarf): Add is_mainfile parameter and pass to dump_dwarf_section. (dump_dwarf_section): Only display debug sections when !is_mainfile and !process_links.
2022-01-18PowerPC64 DT_RELRAlan Modra1-1/+3
PowerPC64 takes a more traditional approach to DT_RELR than x86. Count relative relocs in check_relocs, allocate space for them and output in the usual places but not doing so when enable_dt_relr. DT_RELR is sized in the existing ppc stub relaxation machinery, run via the linker's ldemul_after_allocation hook. DT_RELR is output in the same function that writes ppc stubs, run via ldemul_finish. This support should be considered experimental. bfd/ * elf64-ppc.c (struct ppc_local_dyn_relocs): Renamed from ppc_dyn_relocs. Add rel_count field. Update uses. (struct ppc_dyn_relocs): New.

2022-01-12objdump, readelf: Emit "CU:" format only when wide output is requestedHans-Peter Nilsson3-3/+3
As pre-approved by Alan in https://sourceware.org/pipermail/binutils/2021-September/118019.html and I believe people have run into getting testsuite failures for test-environments with "long" directory names, at least once more since that time. Enough. I grepped the gas, binutils and ld testsuites for "CU:" to catch target-specific occurrences, but I noticed none. I chose to remove "CU:" on the objdump tests instead of changing options to get the wide format, so as to keep the name of the test consistent with actual options; but added it to the readelf options for the gas test as I believe the "CU:" format is preferable. Tested for cris-elf and native x86_64-pc-linux-gnu. binutils: * dwarf.c (display_debug_lines_decoded): Don't check the string length of the directory, instead emit the "CU: dir/name" format only if wide output is requested. * testsuite/binutils-all/dw5.W, testsuite/binutils-all/objdump.WL: Adjust accordingly. gas: * testsuite/gas/elf/dwarf-5-loc0.d: Add -W to readelf options.

2021-11-23AArch64: Add support for AArch64 EFI (efi-*-aarch64).Tamar Christina4-0/+68
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].

2021-11-19RISC-V: Support STO_RISCV_VARIANT_CC and DT_RISCV_VARIANT_CC.Nelson Chu1-0/+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. (get_dynamic_type): Called get_riscv_dynamic_type for riscv targets. (get_riscv_symbol_other): New function. (get_symbol_other): Called get_riscv_symbol_other for riscv targets. gas/ * config/tc-riscv.c (s_variant_cc): Marked symbol that it follows a variant CC convention. (riscv_elf_copy_symbol_attributes): Same as elf_copy_symbol_attributes, but without copying st_other. If a function symbol has special st_other value set via directives, then attaching an IFUNC resolver to that symbol should not override the st_other setting. (riscv_pseudo_table): Support variant_cc diretive. * config/tc-riscv.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Defined. * testsuite/gas/riscv/variant_cc-set.d: New testcase. * testsuite/gas/riscv/variant_cc-set.s: Likewise. * testsuite/gas/riscv/variant_cc.d: Likewise. * testsuite/gas/riscv/variant_cc.s: Likewise. include/ * elf/riscv.h (DT_RISCV_VARIANT_CC): Defined to (DT_LOPROC + 1). (STO_RISCV_VARIANT_CC): Defined to 0x80. ld/ * testsuite/ld-riscv-elf/variant_cc-1.s: New testcase. * testsuite/ld-riscv-elf/variant_cc-2.s: Likewise. * testsuite/ld-riscv-elf/variant_cc-now.d: Likewise. * testsuite/ld-riscv-elf/variant_cc-r.d: Likewise. * testsuite/ld-riscv-elf/variant_cc-shared.d: Likewise. * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated.
