FFT with SIMD Instructions
++++++++++++++++++++++++++

This script generates an FFT that uses AVX intrinsics.  Compare the first two lines
to those in the previous simpler script.

.. code-block:: none

    opts := SIMDGlobals.getOpts(AVX_4x64f);
    transform := TRC(DFT(16)).withTags(opts.tags);
    ruletree := RandomRuleTree(transform, opts);
    icode := CodeRuleTree(ruletree, opts);
    PrintTo("AVX_DFT16.c", PrintCode("AVX_DFT16", icode, opts));
	

PrintTo() writes the code generated by PrintCode() into a file.
