<h3>NAME</h3>
|
|
<tt>llvm-dis</tt>
|
|
|
|
<h3>SYNOPSIS</h3>
|
|
<tt>llvm-dis [options] [filename]</tt>
|
|
|
|
<h3>DESCRIPTION</h3>
|
|
|
|
The <tt>llvm-dis</tt> command is the LLVM disassembler. It takes an LLVM
|
|
bytecode file and converts it into LLVM assembly language or C source code with
|
|
equivalent functionality.
|
|
<p>
|
|
|
|
If filename is omitted, <tt>llvm-dis</tt> reads its input from standard input.
|
|
<p>
|
|
|
|
The default output file for <tt>llvm-dis</tt> is determined by the following logic:
|
|
<ul>
|
|
<li>
|
|
If the input is standard input or the file -, then the output is
|
|
standard output.
|
|
<p>
|
|
|
|
<li>
|
|
If the input filename ends in .bc, then the output filename will be
|
|
identical, except that the .bc suffix will be replaced by the .ll or .c
|
|
suffix (for LLVM assembly language and C code, respectively).
|
|
<p>
|
|
|
|
<li>
|
|
If the input filename does not end in .bc, then the output filename will
|
|
be identical to the input filename, except that the .ll or .c suffix
|
|
will be appended to the filename (for LLVM assembly language and C code,
|
|
respectively).
|
|
</ul>
|
|
|
|
<h3>OPTIONS</h3>
|
|
|
|
<ul>
|
|
<li> -llvm
|
|
<br>
|
|
Instruct <tt>llvm-dis</tt> to generate LLVM assembly code in human
|
|
readable format. This is the default behavior.
|
|
<p>
|
|
|
|
<li> -c
|
|
<br>
|
|
Instruct <tt>llvm-dis</tt> to generate C source code.
|
|
<p>
|
|
|
|
<li> -f
|
|
<br>
|
|
Force overwrite. Normally, <tt>llvm-dis</tt> will refuse to overwrite
|
|
an output file that already exists. With this option, <tt>llvm-dis</tt>
|
|
will overwrite the output file.
|
|
<p>
|
|
|
|
<li> -help
|
|
<br>
|
|
Print a summary of command line options.
|
|
<p>
|
|
|
|
<li> -o <filename>
|
|
<br>
|
|
Specify the output filename. If filename is -, then the output is sent
|
|
to standard output.
|
|
<p>
|
|
|
|
<li> -time-passes
|
|
<br>
|
|
Record the amount of time needed for each pass and print it to standard
|
|
error.
|
|
<p>
|
|
</ul>
|
|
|
|
<h3>EXIT STATUS</h3>
|
|
|
|
If <tt>llvm-dis</tt> succeeds, it will exit with 0. Otherwise, if an error
|
|
occurs, it will exit with a non-zero value.
