...can tune the cost model ---- if other parts of the loop has enough speedup, we don't have to give up entire vectorization simply because masked load/store/gather/scatter aren't supported on the target. If anyone still thinks "early bailout" is valuable, splitting into a separate HWLegal class would be a cleaner approach than what we have today. We should be able to disable/enable it under an option. Let me know what you think. Thanks, Hideki Saito

...the compile time cost is non-negligible then I think we’d still like to keep the early >bailouts in some form.’ It's not like I have specific application code in mind. This all depends on what your code has and how often the emulated code has to kick-in. I'm more than happy to implement HWLegal class, and have early bailout available under the switch. I'm also fine having early bail out as the default if that helps sweeten the deal. :) My intention is to make LV components more modular, reusable, and easier to maintain. Moving things where they actually belong is part of that picture...
