<h3>NAME</h3>
|
|
<tt>gccas</tt>
|
|
|
|
<h3>SYNOPSIS</h3>
|
|
<tt>gccas [options] < filename></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>
|
|
|
|
