 <h3>NAME</h3>
 <tt>gccas</tt>

 <h3>SYNOPSIS</h3>
 <tt>gccas [options] &lt; filename&gt;</tt>

 <h3>DESCRIPTION</h3>

 The <tt>gccas</tt> utility takes an LLVM assembly file generated by the <a
 href="llvmgcc.html">C</a> or <a href="llvmgxx.html">C++</a> frontends and
 converts it into an LLVM bytecode file.  It is primarily used by the GCC front
 end, and as such, attempts to mimic the interface provided by the default system
 assembler so that it can act as a "drop-in" replacement.<p>

 <tt>gccas</tt> performs a number of optimizations on the input program.<p>

 <h3>
 OPTIONS
 </h3>

 <ul>
 	<li> -help
 	<br>
 	Print a summary of command line options.
 	<p>

 	<li> -o &lt;filename&gt;
 	<br>
 	Specify the output filename which will hold the assembled bytecode.
 	<p>

 	<li>-disable-inlining
 	<br>
 	Disable the inlining pass.  By default, it is enabled.
 	<p>

 	<li> -disable-opt
 	<br>
   Disable all assemble-time optimization passes.
 	<p>

 	<li>-enable-correct-eh-support
 	<br>
 	Instruct the -lowerinvoke pass to insert code for correct exception handling
   support.  This is expensive and is by default omitted for efficiency.
 	<p>

 	<li> -stats
 	<br>
 	Print statistics.
 	<p>

 	<li> -time-passes
 	<br>
 	Record the amount of time needed for each pass and print it to standard
 	error.
 	<p>

 	<li> -verify
 	<br>
 	Verify each pass result.
 	<p>
 </ul>

 <h3>
 EXIT STATUS
 </h3>

 If <tt>gccas</tt> succeeds, it will exit with 0.  Otherwise, if an error occurs,
 it will exit with a non-zero value.
