2022-02-03Support symbol+offset lookup in addr2lineAndi Kleen2-13/+80
The Linux kernel usually ouputs symbol+offset instead of plain code addresses these days, to avoid leaking ASLR secrets and to handle dynamically loaded modules. Converting those with addr2line is somewhat involved: it requires looking up the symbol first using nm and then manually compute the offset, and then pass it to addr2line. This patch implements the necessary steps directly in addr2line, by looking up the symbol (with demangling if needed) and computing the offset. It's possible that a symbol is ambigious with a hex number. In this case it uses the symbol lookup if the string contains a +. When it isn't ambigious the + is optional.

2022-01-29objcopy --only-keep-debugAlan Modra1-3/+3
From: Peilin Ye <peilin.ye@bytedance.com> objcopy's --only-keep-debug option has been broken for ELF files since commit 8c803a2dd7d3. 1. binutils/objcopy.c:setup_section() marks non-debug sections as SHT_NOBITS, then calls bfd_copy_private_section_data(); 2. If ISEC and OSEC share the same section flags, bfd/elf.c:_bfd_elf_init_private_section_data() restores OSEC's section type back to ISEC's section type, effectively undoing "make_nobits". * objcopy.c (setup_section): Act on make_nobits after calling bfd_copy_private_section_data.

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.
