For sure. I seem to recall that Ed Jaffe reported great success in using vector instructions for character searches.

I haven't had a chance to use it yet, but it's on my list of vector instructions potentially useful for general coding.

(It's probably model-dependent.) The CLI chain might be optimized by CLI first for the median value and using the outcome to bypass half the remaining tests. -- gil
