<div dir="ltr">Hi Nadav,<div><br></div><div style>I'm interested in knowing how you'll work up the ARM cost model and how easy it'd be to split the work.</div><div style><br></div><div style>As far as I can see, LoopVectorizationCostModel is the class that does all the work, with assistance from the target transform info.</div>
<div style><br></div><div style>Do you think that updating ARMTTI would be the best course of action now, and inspect the differences in the CostModel later?</div><div style><br></div><div style>I also haven't seen anything related to context switches and pipeline decisions on the cost model, another issue that will be quite different between targets and sub-targets (especially in ARM world). But that can wait...</div>
