<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>
