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