opt [options] &lt; filename&gt;
opt [options] [filename]

DESCRIPTION
</h3>
The opt command is the LLVM optimizer. It takes LLVM bytecode as input, runs
the specified optimizations on it, and then outputs the optimized code in LLVM
the specified optimizations on it, and then outputs the optimized LLVM
bytecode.
<p>
The optimizations available via opt depend upon what libraries it was linked
with, as well as any additional libraries that have been loaded with the -load
option. Use the -help option to determine what optimizations you can use.

If no filename is specified on the command line, opt reads its input from

If an output filename is not specified with the -o option, opt writes its
