.SH NAME
llvm-objdump \- LLVM's object file dumper
.SH SYNOPSIS
.sp
\fBllvm\-objdump\fP [\fIcommands\fP] [\fIoptions\fP] [\fIfilenames...\fP]
.SH DESCRIPTION
.sp
The \fBllvm\-objdump\fP utility prints the contents of object files and
final linked images named on the command line. If no file name is specified,
\fBllvm\-objdump\fP will attempt to read from \fIa.out\fP\&. If \fI\-\fP is used as a
file name, \fBllvm\-objdump\fP will process a file on its standard input
stream.
.SH COMMANDS
.sp
At least one of the following commands are required, and some commands can be
combined with other commands:
.INDENT 0.0
.TP
.B \-d, \-disassemble
Display assembler mnemonics for the machine instructions. Disassembles all
text sections found in the input file(s).
.UNINDENT
.INDENT 0.0
.TP
.B \-D, \-disassemble\-all
Display assembler mnemonics for the machine instructions. Disassembles all
sections found in the input file(s).
