Description

Get the cost estimate ignoring thresholds. This is similar to getInlineCost when passed InlineParams::ComputeFullInlineCost, or a non-null ORE. It uses default InlineParams otherwise. Contrary to getInlineCost, which makes a threshold-based final evaluation of should/shouldn't inline, captured in InlineResult, getInliningCostEstimate returns: - None, if the inlining cannot happen (is illegal) - an integer, representing the cost.
