...hat it will do is cause the loop header to be excessively heavy wrt its parent in the block frequency analysis. In this particular case, you get something like: ---- Block Freqs ---- entry = 1.0 entry -> if.else = 0.375 entry -> if.then = 0.625 if.then = 0.625 if.then -> if.end3 = 0.625 if.else = 0.375 if.else -> for.cond.preheader = 0.37487 if.else -> if.end3 = 0.00006 for.cond.preheader = 0.37487 for.cond.preheader -> for.body.lr.ph = 0.37463 for.cond.preheader -> for.end = 0.00018 for.body.lr.ph = 0.37463 for.body.lr.ph -> for.body =...

I am starting to use the sample profiler to analyze new performance opportunities. The loop unroller has popped up in several of the benchmarks I'm running. In particular, libquantum. There is a ~12% opportunity when the runtime unroller is triggered. This helps functions like quantum_sigma_x (http://sourcecodebrowser.com/libquantum/0.2.4/gates_8c_source.html#l00149). The function accounts
