llvm-objdump - LLVM's object file dumper
llvm-objdump [commands] [options] [filenames...]
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.
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 executable 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 symbol 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).
This operation is only currently supported for COFF and Mach-O
object files.
- -v, --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 specifying
--archive-headers, --file-headers, --private-headers,
--reloc, --section-headers, and --syms.
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 52 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. Available options:
- reg-names-std: ARM only (default). Print in ARM 's instruction set
documentation, with r13/r14/r15 replaced by sp/lr/pc.
- reg-names-raw: ARM only. Use r followed by the register
number.
- no-aliases: AArch64 and RISC-V only. Print raw instruction mnemonic
instead of pseudo instruction mnemonic.
- numeric: RISC-V only. Print raw register names instead of ABI
mnemonic. (e.g. print x1 instead of ra)
- att: x86 only (default). Print in the AT&T syntax.
- intel: x86 only. Print in the intel syntax.
- --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 --mattr=help to
display the available attributes.
- --no-leading-addr
- When disassembling, do not print leading addresses.
- --no-print-imm-hex
- Do not use hex format for immediate values in disassembly output
(default).
- --no-show-raw-insn
- When disassembling, do not print the raw bytes of each instruction.
- --prefix=<prefix>
- When disassembling with the --source option, prepend prefix
to absolute paths.
- --prefix-strip=<level>
- When disassembling with the --source option, strip out level
initial directories from absolute paths. This option has no effect without
--prefix.
- --print-imm-hex
- Use hex format when printing immediate values in disassembly output.
- -S, --source
- When disassembling, display source interleaved with the disassembly.
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.
- --symbolize-operands
- When disassembling, symbolize a branch target operand to print a label
instead of a real address.
When printing a PC-relative global symbol reference, print it
as an offset from the leading symbol.
Only works with PowerPC objects or X86 linked images.
- Example:
- A non-symbolized branch instruction with a local target and pc-relative
memory access like
cmp eax, dword ptr [rip + 4112]
jge 0x20117e <_start+0x25>
might become
<L0>:
cmp eax, dword ptr <g>
jge <L0>
- --triple=<string>
- Target triple to disassemble for, see --version for available
targets.
- -w, --wide
- Ignored for compatibility with GNU objdump.
- --x86-asm-syntax=<style>
- Deprecated. When used with --disassemble, choose style of code to
emit from X86 backend. Supported values are:
- 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>.
- --arch=<architecture>
- Specify the architecture to disassemble. see --version for
available architectures.
