|
|
========================================
|
|
|
|
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.
|
|
|
|

|
differently when used with ``-macho``.
