 SYNOPSIS

-llvm-dis [options] &lt; filename&gt;
+llvm-dis [options] [filename]
 <h3>
 DESCRIPTION
 </h3>
 
 The llvm-dis command is the LLVM disassembler.  It takes an LLVM bytecode file
-and converts it into one of several human readable formats.
+and converts it into LLVM assembly language or C source code with equivalent
+functionality.
+<p>
+
+If filename is omitted, llvm-dis reads its input from standard input.
+<p>
+
+The default output file for llvm-dis 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>
 
-By default, llvm-dis places its output in filename.ll, removing the .bc suffix
-if it exists.
