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:: -arch=<architecture>

  Specify the architecture to disassemble. see -version for available
