8 .Sh NAME
9 .Nm llvm-objdump
10 .Nd LLVM object file dumper
11 .Sh SYNOPSIS
12 .Nm llvm-objdump
13 .Op Ar options
14 .Ar objfile ...
15 .Sh DESCRIPTION
16 .Nm
17 prints the contents of object files and final linked images named on the
18 command line.
19 If no file name is specified,
20 .Nm
21 will attempt to read from
22 .Pa a.out .
23 If
24 .Pa -
25 is used as a file name,
26 .Nm
27 will process a file on its standard input stream.
28 .Nm
29 accepts many of the same command line arguments as GNU objdump.
