LLVM-DWARFDUMP(1) LLVM LLVM-DWARFDUMP(1) NAME llvm-dwarfdump - dump and verify DWARF debug information SYNOPSIS llvm-dwarfdump [options] [filename ...] DESCRIPTION llvm-dwarfdump parses DWARF sections in object files, archives, and .dSYM bundles and prints their contents in human-readable form. Only the .debug_info section is printed unless one of the section-specific options or --all is specified. If no input file is specified, a.out is used instead. If - is used as the input file, llvm-dwarfdump reads the input from its standard input stream. OPTIONS -a, --all Dump all supported DWARF sections. --arch=<arch> Dump DWARF debug information for the specified CPU architecture. Architectures may be specified by name or by number. This op- tion can be specified multiple times, once for each desired ar- chitecture. All CPU architectures will be printed by default. -c, --show-children Show a debug info entry's children when selectively printing with the =_offset_ argument of --debug-info, or options such as --find or --name. --color Use colors in output. -f <name>, --find=<name> Search for the exact text <name> in the accelerator tables and print the matching debug information entries. When there is no accelerator tables or the name of the DIE you are looking for is not found in the accelerator tables, try using the slower but more complete --name option. -F, --show-form Show DWARF form types after the DWARF attribute types. -h, --help Show help and usage for this command. --help-list Show help and usage for this command without grouping the op- tions into categories. -i, --ignore-case Ignore case distinctions when using --name. -n <name>, --name=<name> Find and print all debug info entries whose name (DW_AT_name at- tribute) is <name>. --lookup=<address> Look up <address> in the debug information and print out the file, function, block, and line table details. -o <path> Redirect output to a file specified by <path>, where - is the standard output stream. -p, --show-parents Show a debug info entry's parents when selectively printing with the =_offset_ argument of --debug-info, or options such as --find or --name. --parent-recurse-depth=<N> When displaying debug info entry parents, only show them to a maximum depth of <N>. --quiet Use with --verify to not emit to STDOUT. -r <N>, --recurse-depth=<N> When displaying debug info entries, only show children to a max- imum depth of <N>. --statistics Collect debug info quality metrics and print the results as ma- chine-readable single-line JSON output. --summarize-types Abbreviate the description of type unit entries. -x, --regex Treat any <name> strings as regular expressions when searching with --name. If --ignore-case is also specified, the regular ex- pression becomes case-insensitive. -u, --uuid Show the UUID for each architecture. --diff Dump the output in a format that is more friendly for comparing DWARF output from two different files. -v, --verbose Display verbose information when dumping. This can help to debug DWARF issues. --verify Verify the structure of the DWARF information by verifying the compile unit chains, DIE relationships graph, address ranges, and more. --version Display the version of the tool. --debug-abbrev, --debug-addr, --debug-aranges, --debug-cu-index, --de- bug-frame [=<offset>], --debug-gnu-pubnames, --debug-gnu-pubtypes, --debug-info [=<offset>], --debug-line [=<offset>], --debug-line-str, --debug-loc [=<offset>], --debug-loclists [=<offset>], --debug-macro, --debug-names, --debug-pubnames, --debug-pubtypes, --debug-ranges, --debug-rnglists, --debug-str, --debug-str-offsets, --debug-tu-index, --debug-types, --eh-frame [=<offset>], --gdb-index, --apple-names, --apple-types, --apple-namespaces, --apple-objc Dump the specified DWARF section by name. Only the .debug_info section is shown by default. Some entries support adding an =_offset_ as a way to provide an optional offset of the exact entry to dump within the respective section. When an offset is provided, only the entry at that offset will be dumped, else the entire section will be dumped. @<FILE> Read command-line options from _FILE_. EXIT STATUS llvm-dwarfdump returns 0 if the input files were parsed and dumped suc- cessfully. Otherwise, it returns 1. SEE ALSO dsymutil(1) AUTHOR Maintained by the LLVM Team (https://llvm.org/).
