+llvm-objdump - LLVM's object file dumper
+========================================
+
+SYNOPSIS
+--------
+
+:program:`llvm-objdump` [*commands*] [*options*] [*filenames...*]
+
+DESCRIPTION
+-----------
+The :program:`llvm-objdump` utility prints the contents of object files and
+final linked images named on the command line. If no file name is specified,
+:program:`llvm-objdump` will attempt to read from *a.out*. If *-* is used as a
+file name, :program:`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:
+
+.. option:: -d, -disassemble
+
+ Display assembler mnemonics for the machine instructions. Disassembles all
+ text sections found in the input file(s).
+
+.. option:: -D, -disassemble-all
+
+ Display assembler mnemonics for the machine instructions. Disassembles all
+ sections found in the input file(s).
+
+.. option:: -help
+
+ Display usage information and exit. Does not stack with other commands.
+
+.. option:: -r
+
+ Display the relocation entries in the file.
+
+.. option:: -s
+
+ Display the content of each section.
+
+.. option:: -section-headers
+
+ Display summaries of the headers for each section.
+
+.. option:: -t
+
+ Display the symbol table.
+
+.. option:: -version
+
+ Display the version of this program. Does not stack with other commands.
+
+OPTIONS
+-------
+:program:`llvm-objdump` supports the following options:
+
+.. option:: -arch=<architecture>
+
+ Specify the architecture to disassemble. see ``-version`` for available
+ architectures.
+
+.. option:: -cfg
+
+ Create a CFG for every symbol in the object file and write it to a graphviz
+ file (Mach-O-only).
+
+.. option:: -dsym=<string>
+
+ Use .dSYM file for debug info.
+
+.. option:: -g
+
+ Print line information from debug info if available.
+
+.. option:: -m, -macho
+
+ Use Mach-O specific object file parser. Commands and other options may behave
+ differently when used with ``-macho``.
+
+.. option:: -mattr=<a1,+a2,-a3,...>
+
+ Target specific attributes.
+
+.. option:: -mc-x86-disable-arith-relaxation
+
+ Disable relaxation of arithmetic instruction for X86.
+
+.. option:: -stats
+
+ Enable statistics output from program.
+
+.. option:: -triple=<string>
+
+ Target triple to disassemble for, see ``-version`` for available targets.
+
+.. option:: -x86-asm-syntax=<style>
+
+ When used with the ``-disassemble`` option, choose style of code to emit from
+ X86 backend. Supported values are:
+
+ .. option:: att
+
+ AT&T-style assembly
+
+ .. option:: intel
+
+ Intel-style assembly
+
+
+ The default disassembly style is **att**.
