LLVM-OBJDUMP(1) LLVM LLVM-OBJDUMP(1) NAME llvm-objdump - LLVM's object file dumper SYNOPSIS llvm-objdump [commands] [options] [filenames...] DESCRIPTION The llvm-objdump utility prints the contents of object files and final linked images named on the command line. If no file name is specified, llvm-objdump will attempt to read from a.out. If - is used as a file name, llvm-objdump will process a file on its standard input stream. COMMANDS At least one of the following commands are required, and some commands can be combined with other commands: -a, --archive-headers Display the information contained within an archive's headers. -d, --disassemble Disassemble all text sections found in the input files. -D, --disassemble-all Disassemble all sections found in the input files. --disassemble-symbols=<symbol1[,symbol2,...]> Disassemble only the specified symbols. Takes demangled symbol names when --demangle is specified, otherwise takes mangled sym- bol names. Implies --disassemble. --dwarf=<value> Dump the specified DWARF debug sections. The supported values are: frames - .debug_frame -f, --file-headers Display the contents of the overall file header. --fault-map-section Display the content of the fault map section. -h, --headers, --section-headers Display summaries of the headers for each section. --help Display usage information and exit. Does not stack with other commands. -p, --private-headers Display format-specific file headers. -r, --reloc Display the relocation entries in the file. -R, --dynamic-reloc Display the dynamic relocation entries in the file. --raw-clang-ast Dump the raw binary contents of the clang AST section. -s, --full-contents Display the contents of each section. -t, --syms Display the symbol table. -T, --dynamic-syms Display the contents of the dynamic symbol table. -u, --unwind-info Display the unwind info of the input(s). --version Display the version of the llvm-objdump executable. Does not stack with other commands. -x, --all-headers Display all available header information. Equivalent to specify- ing --archive-headers, --file-headers, --private-headers, --reloc, --section-headers, and --syms. OPTIONS llvm-objdump supports the following options: --adjust-vma=<offset> Increase the displayed address in disassembly or section header printing by the specified offset. --arch-name=<string> Specify the target architecture when disassembling. Use --version for a list of available targets. -C, --demangle Demangle symbol names in the output. --debug-vars=<format> Print the locations (in registers or memory) of source-level variables alongside disassembly. format may be unicode or ascii, defaulting to unicode if omitted. --debug-vars-indent=<width> Distance to indent the source-level variable display, relative to the start of the disassembly. Defaults to 40 characters. -j, --section=<section1[,section2,...]> Perform commands on the specified sections only. For Mach-O use segment,section to specify the section name. -l, --line-numbers When disassembling, display source line numbers. Implies --disassemble. -M, --disassembler-options=<opt1[,opt2,...]> Pass target-specific disassembler options. Currently supported for ARM targets only. Available options are reg-names-std and reg-names-raw. --mcpu=<cpu-name> Target a specific CPU type for disassembly. Specify --mcpu=help to display available CPUs. --mattr=<a1,+a2,-a3,...> Enable/disable target-specific attributes. Specify --mcpu=help to display the available attributes. --no-leading-addr When disassembling, do not print leading addresses. --no-show-raw-insn When disassembling, do not print the raw bytes of each instruc- tion. --print-imm-hex Use hex format when printing immediate values in disassembly output. -S, --source When disassembling, display source interleaved with the disas- sembly. Implies --disassemble. --show-lma Display the LMA column when dumping ELF section headers. Defaults to off unless any section has different VMA and LMAs. --start-address=<address> When disassembling, only disassemble from the specified address. When printing relocations, only print the relocations patching offsets from at least address. When printing symbols, only print symbols with a value of at least address. --stop-address=<address> When disassembling, only disassemble up to, but not including the specified address. When printing relocations, only print the relocations patching offsets up to address. When printing symbols, only print symbols with a value up to address. --triple=<string> Target triple to disassemble for, see --version for available targets. -w, --wide Ignored for compatibility with GNU objdump. --x86-asm-syntax=<style> When used with --disassemble, choose style of code to emit from X86 backend. Supported values are: att AT&T-style assembly intel Intel-style assembly The default disassembly style is att. -z, --disassemble-zeroes Do not skip blocks of zeroes when disassembling. @<FILE> Read command-line options and commands from response file <FILE>. MACH-O ONLY OPTIONS AND COMMANDS --arch=<architecture> Specify the architecture to disassemble. see --version for available architectures. --archive-member-offsets Print the offset to each archive member for Mach-O archives (requires --archive-headers). --bind Display binding info --cfg Create a CFG for every symbol in the object file and write it to a graphviz file. --data-in-code Display the data in code table. --dis-symname=<name> Disassemble just the specified symbol's instructions. --dylibs-used Display the shared libraries used for linked files. --dsym=<string> Use .dSYM file for debug info. --dylib-id Display the shared library's ID for dylib files. --exports-trie Display exported symbols. -g Print line information from debug info if available. --full-leading-addr Print the full leading address when disassembling. --indirect-symbols Display the indirect symbol table. --info-plist Display the info plist section as strings. --lazy-bind Display lazy binding info. --link-opt-hints Display the linker optimization hints. -m, --macho Use Mach-O specific object file parser. Commands and other options may behave differently when used with --macho. --no-leading-headers Do not print any leading headers. --no-symbolic-operands Do not print symbolic operands when disassembling. --non-verbose Display the information for Mach-O objects in non-verbose or numeric form. --objc-meta-data Display the Objective-C runtime meta data. --private-header Display only the first format specific file header. --rebase Display rebasing information. --universal-headers Display universal headers. --weak-bind Display weak binding information. XCOFF ONLY OPTIONS AND COMMANDS --symbol-description Add symbol description to disassembly output. BUGS To report bugs, please visit <https://bugs.llvm.org/>.
