Totally agree. I have experienced 'ideal' circumstances of 33% taken/untaken branches where you will be hard pressed to make cmov perform better on real life workloads. Pass along other data inputs that do predict better and your cmov becomes a liability.
It's pretty hard to make modern compilers reliably emit cmovs in my experience. I had to resort to inline asm.
