llvm-objdump ā€” 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:

-d, -disassemble

Display assembler mnemonics for the machine instructions. Disassembles all text sections found in the input file(s).

-D, -disassemble-all

Display assembler mnemonics for the machine instructions. Disassembles all sections found in the input file(s).

-help

Display usage information and exit. Does not stack with other commands.

-r

Display the relocation entries in the file.

-s

Display the content of each section.

-section-headers

Display summaries of the headers for each section.

-t

Display the symbol table.

-version

Display the version of this program. Does not stack with other commands.

Options

llvm-objdump supports the following options:

-arch=<architecture>

Specify the architecture to disassemble. see -version for available architectures.

-cfg

Create a CFG for every symbol in the object file and write it to a graphviz file (Mach-O-only).

-dsym=<string>

Use .dSYM file for debug info.

-g

Print line information from debug info if available.

-m, -macho

Use Mach-O specific object file parser. Commands and other options may behave differently when used with -macho.

-mattr=<a1,+a2,-a3,...>

Target specific attributes.

-mc-x86-disable-arith-relaxation

Disable relaxation of arithmetic instruction for X86.

-stats

Enable statistics output from program.

-triple=<string>

Target triple to disassemble for, see -version for available targets.

-x86-asm-syntax=<style>

When used with the -disassemble option, 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.
