@@ -28,6 +28,62 @@ DESCRIPTION
 The llc command compiles LLVM bytecode into assembly language for a specified
 architecture.  The assembly language output can then be passed through a native
 assembler and linker to generate native code.
+<p>
+The choice of architecture for the output assembly code is determined as
+follows:
+
+<ul>
+	<li>
+	If the user has specified an architecture with the -m option, use that
+	architecture.
+	<p>
+
+	<li>
+	Examine the input LLVM bytecode file:
+	<ul>
+		<li>
+		If it specifies little endian and a pointer size of 32 bits, select the
+		x86 architecture.
+		<p>
+		
+		<li>
+		If it specifies big endian and a pointer size of 64 bit pointers,
+		select the SparcV9 architecture.
+	</ul>
+	<p>
+
+	<li>
+	If llc was compiled on an architecture for which it can generate code,
+	select the architecture upon which llc was compiled.
+	<p>
+
+	<li>
+	Print a message to the user asking him or her to specify the output
+	architecture explicitly.
+</ul>
+
+<p>
+
+If filename is not specified, or if filename is -, llc reads its input from
+standard input.  Otherwise, it will read its input from filename.
+<p>
+
+If the -o option is left unspecified, then llc will send its output to standard
+output if the input is from standard input.  If the -o option specifies -, then
+the output will also be sent to standard output.
+<p>
+
+If no -o option is specified and an input file other than - is specified, then
+llc creates the output filename as follows:
+
+<ul>
+	<li>
+	If the file ends in .bc, then the .bc suffix is removed, and the .s suffix
+	is appended.
+	<p>
+	<li>
+	Otherwise, the .s suffix is appended to the input filename.
+</ul>

 DESCRIPTION
 </h3>
 
 The lli command is the LLVM interpreter.  It takes a program in LLVM bytecode
-format and executes it, either using an interpreter or a Just In Time (JIT)
-compiler.
+format and executes it using an interpreter or a Just In Time (JIT) compiler.
+<p>
+
+If filename is not specified, then lli reads its input from standard input.
+<p>
+The optional arguments specified on the command line are passed to the executed
+program as arguments.
+<p>
+
+<h3>
+MAIN FUNCTION
+</h3>
+
+The main() function of the bytecode program is where execution starts.  It
+is passed three arguments:
+
+<ul>
+    <li>
+    int argc - The number of command line arguments.
+    <p>
+
+    <li>
+    char ** argv - The arguments to the program.
+    <p>
+
+    <li>
+    char ** envp - An array of environment variables used by the program.
+</ul>
+
+The first argument to the program is the name of the executed bytecode file
+(with the .bc suffix removed).
