+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:: -disassemble
+
+  Display assembler mnemonics for the machine instructions
+ 
+.. 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:: -macho
+
+  Use Mach-O specific object file parser.
+
+.. 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**.
